It Runs!

I made up the last hose in the week, and poured in a load of fuel to test the pipework. A few leaks from loose joints but no real dramas. I set the regulator to 40psi to get me roughly where I should be to start it and called it quits. I only had a few hours to work on the ’55 on Saturday, so I built the coil unit up with the new module and the MSD coil I got off eBay. It needed drilling out to suit, and I mounted it where it sits on a stock LT1 for now so I could test it. I fitted the elbow, MAF and an air filter and realised it was ready to go. I got in and fitted all the PCM fuses, connected the battery and flicked on the ignition to make sure it all worked. Nothing. No fault light, no fuel pump noise. After a lot of testing I found that I hadn’t connected the earth for the fuel pump relay, and after a load more testing realised I hadn’t put the feed fuse in. Lotsofbitsfitted.jpg With that fitted, I turned the key and the pump buzzed into life. I pulled the fuse back out and spun it over on the starter till I got some oil pressure, then re-fitted the fuse. I was really nervous, and turned the key to start. It fired immediately and ran for a few seconds then died. I was out of time then, but managed to get a few more hours later to have another go. I pulled the MAF plug and gave it another quick go and it ran much better but stalled on returning to idle. You can see a video of it here. I temporarily spliced in the ALDL plug and checked for fault codes with a laptop. It was showing a knock sensor fault, so I checked the wiring then realised it had a Caprice program on the computer which is a 2 knock sensor car. I re-flashed it with a stock Camaro one on Sunday, and fitted the headers and the radiator to check for clearance for the pipework. A quick test fire and it ran like a watch with the MAF connected. It still stalls on return to idle, so I need to check the throttle position sensor is correct and go from there. Pretty chuffed with it all tho. RadPlaced.jpg
