Ok, so I have a 2004 converted to a 3V
Today I changed the cam sensor and road test and it was fine. The car came with an SCT tuner and the check engine light was not illuminating, so I programmed the car back to stock. After that the car will not start. I checked the fuel pump out and all wires at the connector are getting power to them. I can't find any wiring diagrams anywhere. I am starting to lean towards the ECM being no good.
Any other input would be great

 

Ok, here's some input... Don't post the same exact post you did here yesterday:

Because what you then do is split the attention and you'll get nowhere. Stay in the original thread for the best help, and be patient. More there, go there now.
