I pulled out the motor to paint the inside of the hood. (I'm getting the whole car done, so I wanted to paint the engine bay black.) I removed every wiring harness I could remove and rad hoses going to the firewall. I reinstalled everything, and added a 255lp/h fuel pump, 42 lbs/h injectors, 75mm Throttle body, 76mm C&L Maf with correct sampling tube and also sent my SCT Chip to Dave to get it reprogrammed. I also replace the fuel regulator with a new one (for good measure..)
So I turn the key, fires up for 2 seconds... dies. If i want to keep it alive, I have to step on the gas, and even flooring it doesn't do much. If I let go of the gas, it will idle real rough and then die. checked all the plug wires, all in order, plugs are new autolite 103s... checked vacuum lines, all connected. Next morning we tried to fire it up, now it wouldn't even start, but a few times we got BIG backfires. I plugged all the vacuum lines except for the pcv and jammed the bypass valve open, still nothing. Pulled the plugs, smelled like gas very bad, replaced plug started again, and back to square one, runs when you give it some gas, you let it go, it sputters and stalls... not sure what to check next, I don't have a fp gage, but pushing on the shraeder valve gas sprays out, even after the ignition is off. So I know I have pressure (not sure if I have enough though..) So we are thinking I don't have strong spark maybe?. I just need a direction on what to check, change or try?
Thanks,
