I'm experiencing a crank, but no start on my 1996 Cadillac Deville. The car was running previously and it stalled in traffic out of nowhere to which it would no longer start again, I was able to get it towed back home. I checked the fuel pressure when turning the key to the ON position, not START and it goes up to 10psi and then drops to zero within about a second. I am also not receiving any DTC codes pointing me to any issues. From my research I found that 3 of the main problems could be the fuel pump, fuel pressure regulator, or the fuel filter. I am looking for some help and some tips to help me further my investigation into pinpoint what the actual problem could be. Any ideas?
Ok so here is my problem everyone. I have a 1991 Eldorado touring coupe. Recently after driving I stopped to get gas, attempted to start the car and nothing. After trying to start it the in car diagnostic system said the battery was at 11.9. I left, and came back after 40 minutes and it started right up, and the battery read normal again. Now when ever I drive it and turn it off i have to wait at least 45 minutes before starting it up, or it wont start. Everything else inside the car works, stereo, subs, windows etc. Needless to say this is extremely inconvenient, especially with kids in the car. The only code that pops up is E046, left to right fuel imbalance (paraphrased). It come on intermittently, and did not come on the first time this happened. I also notice a ticking noise from the cap and rotor area, so im thinking of replacing that. Can a bad cap and rotor cause that? Just for a background I recently got all motor mounts replaced, and a new fuel pump. When they put the new mounts on they split the hose that connect to the ac (r12). I had them remove it and repair it, and all this started while the hose was removed.They fixed it and put it back on but forgot to plug the compressor back up. I also had to tighten clamps on a fuel line in the back to stop it from leaking fuel. I am new to all this but absolutely love my Eldo, and plan to never get rid of it. I am also a working man who only knows a small amount about cars. Please help me guys so I dont blow my savings dealing with these crooked mechanics in my area.
P0001 Fuel Volume Regulator Control Circuit/Open V0001 [is possibly U0001?] U0001 Controller Area Network (CAN) Bus Communication (ECM) P0300 Engine Misfire Detected P0107 Manifold Absolute Pressure (MAP) Sensor Circuit Low Voltage P0108 Manifold Absolute Pressure (MAP) Sensor Circuit High Voltage P0325 PCM Knock Sensor Circuit P0306 [is possbily P0326?] P0326 Knock Sensor Circuit Excessive Spark Retard It looks like the wiring harness to the sensors under the beauty cover is pulled off. The MAP sensor is in the center of the intake manifold toward the rear. The spark sensor is under the intake manifold in the "lifter valley" (where the cam and lifters are in an OHV V8). I would start by looking for wiring harness damage or things disconnected when your friend pulled off the FPR. Run the codes again, and this time note which ones are CURRENT.
