OK, for sure... you have a loose ground. Somewhere you lost a ground wire to the engine block, the chassis or at the battery. Try not to crank it. This could blow your modules (computers) and make things worse. Just turn the ignition key and hunt down the open ground circuit. I am assuming that your battery is fully charged. Post back with more...
Hi ,im new here.i have a loose ground while trying to start my ford everest.did i just blew my pcm?i checked my pos.supply of my ckp sensor but im only getting 2.3v.
dear sir . could you tell me what is happening with my cruise car . i changed the crankshaft it was damaged but i have P0300,P0303 and P0304 no one knew whats the problem !!!! I replaced ( ignition coils,fuelpump,plugs) and( no leaks ) i checked the injectors no problem with them . I checked the crankshaft with voltmeter ( 2.5vdc wite and blue wire, 2.5vdc green wire and the third wire is black for ground) these readings with ideal engine. are these correct readings I need your helpe sir.
thanks! i recently put in a NEW (but bad) CKP sensor and its apparently shorted internally- screwing up my fuel level gauge, ignition coil/ignitor(?) and setting off a host of other selonoids- et al! I cleaned all grounds, rebuilt my fuse box, new ECU, cleaned everything........no changes UNTIL i just now decided to swap back in the old CKP sensor. All the electrical clicking, etc went away immediately and Im not going thru the KEY RELEARN process for the new ECU
Crank sensor may share 5 volt reference with other sensors. You're not giving me much, such as year make model engine size. Looks to me that something else is the cause.
My cam sensor (3wires) has probably a bad ground form the ECM. With a disconnected sensor the gound measures +3voltage. Looks very suspicious to me. Can i cut the ground wire and mount it directly to the ground? Or does it need to come from the ECM?
The issue is this, if you run a different ground, then the ECM will compare the signal to whatever the ECM thinks it's a ground. That will never work. You need to find where the ECM is grounded.
Dear Sir, Can you plz elaborate the ECU connections in future videos? Such as assigning the connection name @ ECU i-e NE+ and NE- in case of CRK Sensor. It would augment the lesson for sure.
Thank you... I also invite you to review our current SERIES "How to Build Your own Diagnostic Equipment", right here on our FREE channel. Click the link towards the end of the video or click ADPTraining and choose the playlist. Thanks again.
Can a Lighting Control Module on Ford's can cause the engine not to spin? My interior lights head lights are not functioing properly, the car stop on me today then that LCM started to click like crazy and I also had a P0443 code on it evaporated small detection
Can you Mr. Ive been struggling trying to figure out whats been going on 3 mechanical decline shops couldn't figure out what was going on with my cousins 1994 s10 blazer tahoe edition 4.3 cpi or ipc- pci obd none after intake gasket replaced motor would be fine one day the next rain would wash the blazer away. Cousin handed the keys over to me, came with the original window tag $ 21,350 with caset about the csi blazer. Doesn't explain my situation car now starts up runs at tdc 0 prrrr warms up then dies wont restart i noticed the crank sensor on passenger rear head was wobbling around and hand tightened. My question is this would that create my problem?
I have a 1997 Jeep Grand Cherokee Laredo. It lost power and shut down. During my testing of the CPS I found I no longer have 12 volts at my wiring harness to the CPS. Didn't know if there is an actual test or how to see where I am losing the power.
Hi..my car cps sensor hv 3 wire, can u make vid using 3wires sensor and how to chck the reading 2. What is the sensor type? Magnetic or proximity or else
Good day sir thanks for these useful information and knowledge shared I just want to ask some issue regarding IMRC solenoid malfunction on chevrolette lumina model 2007 v6 engine intermittent issue how does it really works? thanks a lot and more power
My1999supercharge estimate not getting any egnition current change coil and.crank sensor and the still. No current check ecu its OK need some help.please
I have a 2003 Mercury Grand Marquis Gs When I turn the key the motor doesn't spin and the light on the dash dime a little but when turn the key I see no charging light but when I turn the key to start the brake light get brighter
