The car is back again. I have tried the suggestions. Sprayed carb cleaner in intake and it did fire. I swiched the ignition and it would not turn over. I then switched the body control computer, main computer and ignition,(diconected the factory radio so it would not lock) from a known good running car. Did the same thing it cranks over has spark but no fuel pressure. I had a friend crank it over while I checked to see if power went to relay, it does. Pulled the fuel pump cover of and it is not getting power there. Put power to fuel pump and it turned on and car will start. I do not think it is the security as when i switched just the ignition it would not even turn over with the security light on. Any other ideas? Thank you
