I started the vehicle and it ran perfect until my wife took a 65 mile journey. She turned the car off and did her thing then came back to leave and it would not start. The starter would engage and turn the engine over but it wouldn't start. I had a look at it and found out there was not a spark to be found from the coil pack.
I pulled out the trusty multimeter and went to work on it. I tested the coil pack and it was within spec and was not malfunctioning. I tested the signal wire going to the coil and it was not sending a signal from the PCM to the coil to spark. I then tested the CKP sensor and I found it perfectly within spec and even replaced it again to be certain. Whil replacing it I looked at the crankshaft an noticed nothing wrong. No wear and tear to it and it looked in good shape for what I could see through a 3/4 inch hole. I then tested the CMP sensor and it checked out fine as well. Both sensor wires had perfect voltage of 5 volts and were sending signal.
Now I'm not throwing ANY codes. Not a one. The CKP/CMP sensor timing belt code no longer showed as it shouldn't since every one of them was replaced. My question is, could my PCU or ECM have gone bad or even my power distribution unit? I dont see what else could cause the coil to not recieve signal and NOT throw any codes.
One time there was a momentary charge on the ASD relay output (harness side) but after that nothing. After several attempts to get a reading off of it there was nothing.
ANY HELP ON THIS HEADACHE WOULD BE MOOOOOSSSSSST APPRECIATED! Thank you in advance.
have the same problem?
