Short background: I tore down the top end to replace the head gasket, which had a leak. It started prior to me doing so. This is the first time I've ever done it, but everything seems to have gone well enough. I got the head machined, and the valves looked at from a highly reputable machine shop in my city, and put back together more or less without issue. I gapped the valves to spec when putting everything together. While I was doing that I also replaced the timing belt, drive belts, thermostat, water pump, fan clutch, radiator, throttle body gasket, exhaust manifold gaskets, intake manifold gaskets, and return line gasket (little triangular one off of the intake manifold to the fuel pressure regulator). Now it won't start. The engine cranks, and I'm getting a nice even churn from the starter. It feels and sounds strong, but it won't turn over. Not even a little bit.
So far I've done/checked the following:
- new crankshaft position sensor
- new spark plugs (NGK)
- spark plugs are gapped and seated correctly
- new ignition coil
- new distributor cap
- new distributor rotor
- new fuel hoses and hose clamps, all three (main line was cracked and leaking)
- tank drained and new gas put in (it had been sitting a while, and wanted to make sure i wasn't putting bad gas through)
- physically made sure fuel was coming from the main line
- since fuel is coming through the line i'm assuming the fuel pump and subsequent relays are working
- checked the fuses, and anything that seemed like it would be pertinent looked unbroken and functional
What I haven't checked yet (and is a constantly diminishing list):
- other relays, not really sure how to check those
- ignition wire harness (though that's next to be replaced since i'm already here replaced everything else)
- fuel pressure could be a problem, and i haven't checked it yet
- DME (i really don't know how or why this would've gotten borked in this whole process, so I haven't figured it as a possible issue)
- Fuel injectors, maybe?
-Compression
Really that's it. I'm a novice at most of this, and all the knowledge I have is academic from a metric ton of googling and reading. Are the things I haven't checked yet even a likely culprit? Are there things I'm not finding or thinking of? Any and all advice would be greatly appreciated.
Thanks!
