Re: Car cranks but no spark
Spoon12 Assuming what you said in first post is correct and you aren't getting spark at any of your coils, the problem is common to all coils. That indicates a ground problem.
First thing to do is unscrew the nut at ground 101 which is below the neck of the fill tank of the windshield washer and clean it really well. A little carbon black applied is always a good idea. That ground 101 is for the PTCM. The other ground common to the coils is 104 which is located at the front of the engine. Both grounds will have brown wires connected to them. Be certain they are clean with good contact. The engine itself is grounded under the car with a braided large wire on the driver's side which has been know to developed corrosion, so be certain to check that also as many have replaced it.
If that doesn't work then it is time to break out the wiring diagrams and do some diagnostics.
PS Use only Bosch CPS
