In this video I discuss some tips on diagnosing early model Volvo Penta EGC engines which have the round white Data link connector for connecting to Diacom.
Very helpful. I need to know more about my 8.1 lol. Should have realized two years ago when i bought my bought for 70 k these engines are obsolete. Hard to get parts for.ie knock sensors. I just bought an 8.1 gm knock sensor and a Diacom scanner. So wish me luck. I have multiple issues. Check engine lights and in limp mode. Low oil pressure 6psi at idle. So we will see how deep this goes. Shake my head at this.I hope you have more videos on the Volvo penta
Great explanation on the older models. I have a 2007 Volvo Gi-G motor. ECM # 3818613. New rebuilt Jasper motor installed this winter. Weird problem started at idle. After its warmed up (around 10 minutes) The idle will start to incrementally rise until it hits 1300 rpm then stop and stay there. If I stop the motor for 10 seconds and restart it... It goes right back to 650 rpm for another 10 minutes or so then climbs again. My shop scanned it with the Rinda tool and no DTC codes. All parameters normal. Test TPS didn't help. Runs perfect at speed. vacuum test ok, fuel pressure high/low ok. Replaced IAC Valve, TPS, T-Map, ECT Sensor, precautionary. Battery terminals cleaned & 12.6v, alternator is new with 14v charging, Block ground has zero resistance, Cleaned ECM pins and plug as well as mounting surfaces & hardware. Nothing helps. Before pulling the trigger on a super expensive ECM to swap & see if it follows.... Do you have any words of wisdom or things to possibly check. I am going to check the ECM plug grounds for resistance next. I can't find any info on this crazy issue anywhere. Thanks. Keep up the good work. I hope this helps someone else someday.
@@tedsmarinerepair8956 So are you saying the Jasper Engine is bad? Still waiting on my backordered ECM. While waiting, I re-cleaned my throttle body and verified the throttle cable is adjusted properly. Still doing the same RPM rise after 10 minutes or so.
I have Volvo penta 8.1 GXI gasoline engines I was traveling down river both engines running great picked up a mooring settle for about a half an hour to an hour started them back up headed up river and my starboard engine decided it wanted to not stay running, so I ended up coming back on one engine, but the starboard engine. Every time I started it it would vibrate, not severely, but it had a slight vibration, and it would not throttle up, and when I left it running, eventually it would shut down, almost like if it was starving for fuel what should I be looking for?
My 8.1 Volvo could not get on plain, it kept surgin between 2500-3000 RPM. I replaced one of the spark plugs and cleaned the rest. That seems to fix the issue but I am still thinkning that it could be something else. Any ideas what would cauze engine to hezitate and stater at highter RPM? Thank youi
I've been told that volvo penta stopped painting the inside of their fuel cells about 10 years ago and now coat them with black chromate that wont flake like the previous units did. Any idea how you can tell which units or model #'s are chromate?
What is a good scanner tool to buy for a 2005 Volvo penta 8.1 gii-f ? I would like to read codes and troubleshoot my own boat. Thanks great video- subscribed
Hi, I have a pair of 5.7 GXi-C’s and my starboard motor will die when coming off plane and returning to idle. Port is fine. Where to start trying to diagnose ? I can take parts from port and move to starboard for troubleshooting
Hi Ted. Enjoy you videos. I have a question if you dont mind trying to figure out. I have a 2006 volvo penta 5.7 Gi. It starts cold every time(no problem). After running boat for 15 min or so it will not start. I have to give it throttle. Then it will start. It is a gas fuel injected engine. Any thoughts. Thanks Brian seaford Long Island
Hi Ted, I came across your videos and now I'm a fan. I'm sure you are pretty busy, but if you could spare a few minutes to help me I would really appreciate it. I have a 2006 Volvo Penta 5.7 Gi-F. When its cold it start right up and it runs great for hours as long as I do not turn it off. If I turn it off after its warm 20min later or an hour later it will not start back up unless I put it in neutral and throttle it forward and try starting it again its starts revved high and I slowly bring it back to neutral and then I can be on my way. To avoid this I leave it on for hours while fishing in the ocean. I've taken it to two different shops and none have been able to resolve it. It;s been this way for the last 10yrs at least. I would greatly appreciate any insight as with gas prices going up again here in CA I can't afford to waste all that fuel on every trip out. - Thx
@@peterhoffmann3536 not yet unfortunately. Switch out the fuel pressure regulator with no luck. Next up is swapping out the throttle position sensor. Tested the high and low fuel pressure pumps and those are fine. So not sure what it could be and BTW I dis take it to a shot that said it turned on and off no problem but the problem persists once you’re actually on the water.
Hello I had a similar problem on a VP 5.0 Gi PEFS. It was the water temperature sensor which did not sent the right information to the ECU. Hope this can help you.
Hello there , I have a 2001 regal fastrac with a Volvo penta engine 6 cylinder . I have a couple of questions. I did a compression test on all cylinder and all of them read 150 and 1 reads 120. Is that still good ? Second I finally got the engine running nice and smooth until I put it in the water to test . It kept shutting off every time I put it into gear . I kept doing it like 7 times till it won’t start any more and if it does starts it would die right away . Y Thanks in advance
Hi Ted, thanks for your video. I have a question about my Volvo Penta GICE - 300R Red engine. Last weekend while underway it stalled and it showed camshaft failure on my screen, I waited a few minutes and the engine started right away and when I tried to accelerate to get on plane the alarm came on and it showed misfires on some of the cylinders. We were able to get back in at about eight miles an hour. The engine went on safety mode. Can you please help me with what could be causing this.Thank you in advance.Carmelo Galea.
My Volvo Penta 4.3 Gxi from 2004 starts directly and runs perfectly at low speed (max 2500 to 3000 rpm)... but when I go 3500 rpm high speed he stops directly (like everything falls out). When I restart he doesn't run anymore. When I unleashed the high pressure fuel pump the fuel flow a few seconds when turning the contact key. After reinstalling the high pressure pump connection at the top and I want to start the motor runs perfect without any problem. So it means there must be falls air or mealy a electrical problem with the fuel pump a high speed... What could it be? Thank you for your advice ;-)
@@tedsmarinerepair8956 Thank you for your reaction. The debate mode is only when I go more than +- 3000 rpm, under I can navigate for hours. When I turn the contact key the motor sounds alarm, then I can hear the full pump for a few seconds and he starts perfect. Also the motor runs great. I'm thinking about the high pressure pump, fuel sensor or meaby the fuel pressure regulator ????
@bartoers7735 I really don't want to speculate on the cause without some more testing. I would suggest taking the boat for a ride with a fuel pressure gauge installed to determine if the fuel pressure is indeed dropping off. Also a Diacom recording while running it from low to high speed would be very informative.
@@tedsmarinerepair8956 we found it 😅… it was a problem in the cable connection to the crankshaft sensor. New cable and problem solved. 🤷♂️… thank you for your reply and help … with the diacam we found it very quickly btw
I have a 2006 5.0l gxi, crank, no start. last year i goosed the throttle in neutral at idle and it quit and would not restart.....sound like a timing issue....pulled distributor because I found it loose, gear is worn....waiting for a new distributor. Is there anything i should be looking out for? I don't have a scan tool but i'm a certified automotive mechanic.....just looking for a couple tricks or tips to get back in the water. any help would be greatly appreciated.
Hi Ted. I have a 8.1 penta and it will crank but won’t start if I turn the key and not hear an audible beep. If the beep is there I can start no problem. It does it quite a lot now. Is that relating to the purple wire you were mentioning?
A little more info on the engine model and Serial # to determine if it's a MEFI or EGC engine will help. They are different and I want to b e sure to point you in the right direction
Hey Ted iv got a volvo penta 8.1 just like the one in the video the starter has strait power to key side of the starter all the time. It cranked and cranked wouldnt shut off I went to the key tested theres no power also removed the ignition fuse and ignition relay still has power to the starter I can't find a wiring diagram any where for these egc models to be back feeding into the key side of the starter ? and feeding power all the time I see something about a 1 way diode but with no diagrams its hard thanks so much if you reply
@@tedsmarinerepair8956 3869370 is the top number 4012203628 is the bottom number 8.1 GI-H THANKS alot for any info you can provide very much apreciated!!
hi, i have volvo penta 8.1 Gi-H once i start the fuel pump start but engine doesn't crank and temperature cage is full up please guide me with some tips
hi Ted thanks for response i done some testing the engine does crank but no spark i found rust and in side the throttle body stuck and does not move once i switch the power key i clean the rust and test throttle body does move and go back but still crank and no spark do you think the throttle body is damage and i need to replace
@@walterbuti9988 if it is an EVC engine then it's capable and the can wires are in the main harness already. If not then your stuck with what you have in the engine harness.
@@tedsmarinerepair8956 I’m a student at MMI and I’m having trouble identifying what mefi type like when I’m looking at a engine wiring diagram and model numbers. Like would mefi pertain to the version in the model number? Feel like I should know all this already a week into the 3 week course and still trying to pull it together with identification.
@@tedsmarinerepair8956 I know what all the letters mean in the model number but unsure what mefi type it is. Guess in short I’m asking how would I look at a engine wiring diagram and know right off the bat what one it is?
@@shisuiuchiha399 Sorry to hear that, you should have come to New England Tech for an associates degree in Marine Technology. I teach our Fuel Injection class and that is one of the first lessons on identification of which MEFI or EGC or Motorola or Delphi processor you are working on. MEFI is variable depending on the year not so much the model of the engine.
@@tedsmarinerepair8956 it’s in my notes I was just curious if you would be able to see the engine wiring diagram of different engines and know without any other info except engine diagram
