Okay, it started with the alternator. Came home one day and it was smoking, so I replace alternator but it was not charging.
I replace it with another new still no charge, test battery all my fuses and relays all are good, so the PCM was the only thing to stop it from charging. So yes I replace the PCM still not charging. I went around the block the check engine light and the lighting bolt light came on. All at once I had no throttle car will only go 20 MPH got home pulled PCM sent it back to have it check and they sent me another one in between of it all I replace the crank and the cam sensor also the fuse box under the hood. Now at this time I have no spark from the coils, fuel pump is good. I checked for codes, have no codes. Help please!

Good morning.

When you turn on the key, does the check engine light come on?

Do you have fuel pressure?

When you crank the engine, does the tachometer move up a little while cranking? This will tell me if the crank sensor is working.

Smoking? Do you mean electrical smoking? If it is, check the harness carefully for any damaged or burned wires.

Did you check all fuses with a test light for power on both sides?

A lot to check, sorry, but I am not there.
