Guys, I haven't been active on this forum for over a year because I've been out in the garage building. My 1977 280Z conversion to a 5.7L (350 cid) TPI V8 with World Class T5 is now complete, sort of... After weeks of startup attempts and reading SES codes I'm not much closer to firing it up. I did find a bad fuel pump relay and replaced that. I temporarily relocated my battery from the cargo area back to the front to shorten the cables, just in case. I verified 46 psi of fuel pressure at the rails, and spark at the plugs. I've tried to start it so many times now I'm getting concerned about re-priming the oil pump. I've been very careful over the two year build using the Helms and GM factory manuals as well as JTR Z V8 and TPI/TBI manuals. My wiring connections were done well. I've added temp-switch controlled electric cooling, Vintage Air AC, upgraded the suspension and brakes, and replaced the fuel and return lines with 3/8" steel tubing and AN-8 fittings. Both cars ran when I started this project. I think it is time to enlist the expertise of a professional auto electrician to figure out what I have missed, or what I may have wired wrong. I kept detailed notes and made new wiring diagrams for everything I changed or added. I kept the VATS, Resistor key, VSS, and all sensors. I've been back over all of those looking for any mistakes and don't see any. But electrical work is not my area of expertise. Can anyone recommend an electrical expert in So. Calif. (I'm willing to trailer the car) who really knows, and is willing to work on a Z conversion? For those of you with years of experience, I know the 5.7L never came with the T5, so I swapped out the 5.0 for a 5.7 in the original car to sort everything out before starting the Z swap. I even had to have it smogged that way before the swap due to bad timing (it passed). The WC T5 is for insurance against excessive torque, but I did not use/test it before starting the swap. It has no impact on my current problems. I also welcome informed input from members of this forum who has successfully done what I'm attempting to do. Any help is appreciated. Thanks, Steve
