you taught us how to test for a regulator thats running rich, how about if it is running lean? if its lean it means there will be no fuel coming out of the vacuum hose right? i know its lean coz i checked the spark plug and it is clean almost white.
2015 Hyundai genesis coupe 3.8 v6 the regulator is ticking/clicks on every time we try to start it, obviously that might be the problem but just want some feedback on what we can do or more things we can confirm confirm that it’s bad, can we use a multimeter
i’m getting a fuel pressure regulator open circuit code when it rains or snows and was wondering if i should replace my regulator or look for damaged wires? only comes on when it rains or snows or super moist out. (2018 gmc Sierra)
My car drives well on fairly flat roads,problem comes when i have go up hill (fairly steep road),the car does not accelerate beyond 40km/hr then it violently stops with bang which sounds like its from the engine bay.it almost stops,gets to a lower gear.If i need to go up steep hills,i have to be gentle on accelerator.Disturbing
My car seem to lose fuel pressure after it's been sitting overnight...... could that be due to a bad fuel pressure regulator not holding pressure? When I go to start up in the morning, it feels like the fuel line is half-empty when I turn car to ON position to prime the fuel pump. Sounds like the pump is also making gurgling sounds like it's having trouble running pressure through the line.
My situation is kinda similar , but my problem Is I was driving home one night and I lost power like it drove for a few more miles and then suddenly brakes got harder to use and I could no longer go faster got harder to accelerate all my lights were still on still it jus got to crank no start , few weeks after I bought an obd reader it read code p0001 “fuel regulator “ but before I bought it more than 1 person told me it was my fuel pump , I’m jus really lost on which part to purchase
Probably both. I just changed my fuel pump, filter, and injectors. My car is running better but it's still taking a tad longer to start than it should and it stalled after starting once. So I'm going to change the pressure regulator and hope that's the final problem. But if you want to go for the cheapest option, do the pressure regulator first.
My car starts up fine it just sometimes while I'm idling at a stop it loses power and turns off then I could smell raw fuel can this be my pump or the regulator
Sounds like clogged fuel injectors my injector was cracked and it smelled like bad gas check ur fuel injectors are damaged or if u can smell fuel near the injector
Get a Hayes/Haynes manual for your car. Also they have a website online. Part store could also help you locate where that part is. The manual is great, I learned how to do my first brake job with it!
Yes it can it could be bleeding down into the cylinder filling it with gas smell your oil and check to see if the oil smells like gas if it does change the oil and filter asap and fix the injector / injectors the ones that are leaking fuel could also be fuel pressure regulator you can check and test it with a fuel pressure gauge on the fuel rail
Thank you, do you have a video which explains how to check if diesel leaked down and mixed with the oil? I tried to smell the oil but I’m not sure if it’s a normal smell or not
BTW, I performed injectors flow rate test and in 5 minutes all injectors returned equally a 5ml of fuel. But this test is did after i replaced 1 injector that i was suspected that it’s faulty
