Question
yes please, I replaced the timing chain, and sprockets, plus cam sprocket magnet. now car will not start.When trouble shooting I had spark and fuel injector signal and proper fuel pressure. Put the chain on ,now nothing no spark or injector signal. Replaced the computer and ignition model with known working unit. Still nothing. replaced crank sensor and cam sensor with new parts. Still nothing. Have voltage at the coil   and crank seensor. Engine turns over fine. Can you help?

Answer
If you have ignition to the spark plugs and you have fuel to the engine then you need to run a compression test to see what kind of cylinder pressure you have.

Do you have any computer codes ?.

Do you know how to access the computer to get the codes ?.
