I yanked my engine and transmission to replace seals. I also replaced the timing belt and the catalytic converter. I put everything back together (perfectly), but now the car won't start. I am positive the engine is in time--I took the timing cover back off, turned the crank to top dead center on the compression stroke--watched a screwdriver being pushed up to maximum through number one spark plug hole, crank and cam timing marks lined up, rotor pointed at #1 spark plug position. I also put a timing light on it while cranking--10 deg BTDC. At one point, I did get the car to start and run (idle) for a minute or two after cranking it for an extended period of time. It cut off suddenly. I was able to start it one more time, but It died when I took my foot off the accelerator, and I have not been able to start it again. I have replaced the plugs and the wires and have seen a plug fire when held against ground. I have seen a "shot" through each wire via the timing light. I know compression is good because I kept the plugs in while working on the engine and turning the crankshaft was very difficult. I replaced the fuel filter and have now checked fuel pressure--it's right up around 40 PSI when cranking. I have checked all connectors, grounds, and vacuum hoses--I labeled hoses and connectors before disassembly, and I never loosened the grounds on the intake manifold, presumably the grounds for the injectors. I opened the exhaust line before the catalytic converter to ensure I did not have a back pressure problem. I'm about to jumper a test light across the injector connectors. Any suggestions, precautions, surefire trouble shooting techniques--the problem is solid; I should be able to track it down! The can ran before I fixed it!! (Any thoughts on spark strenghth?)
