I finally have my car ready to run but it wont. It cranks and throws out some good flames out of the open headers but will not start. Heres what I have checked so far with no luck. Kind of long but this is what I need expanded on.
turn key halfway, fuel pressure up to 38lbs.
checked and have good spark at least to the number 1 and number 4 cylinders
cranks over fine, starter seems extra loud, don't know if that is normal
timing is set where it should be, we moved dist. gear to every position possible just in case and still no start. We did notice that it at least kind of fires when distributor is in its correct place
Put a known to work DIS and cam sensor in to test that, no change.
Listened while cranking over engine looking for enormous vaccum leaks that may cause a run issue, none found.
Computer is out of a 90 5-speed never used in this car, fyi
Other things that come to mind:
While cranking the vaccum gauge does not move, I have seen it fluctuate slightly a couple times.
While cranking, bypass valve does not move at all.
Vehicle has no coolant in it, gotta fix the leak at the thermostat housing. The coolant temp sensor to the computer wont shut me down will it?
crank sensor is brand new motorcraft, lined up good, firm ride light shuts off after 5 seconds with key turned halfway and does not come on while cranking. Does this mean it is most definitely good?
New bhj balancer.
I'm still back to the drawing board on this one.
Possibilities that I have thought of
Huge vaccum leak that I'm not seeing, *noting the boost gauge with pretty well no movement while cranking.
Compression problem, I don't have a gauge but when we cranked it over with no #1 spark plug in, it blew out some pretty hard air on my hand. On my hand meter, it seemed pretty normal . I had the engine bored .030 over with .030 over pistons. Installation seemed normal. I don't have the tools to check ring gaps though.
Everything is tight I ziptighted every small line and tighted my intercooler pipes nice and snug. The only possible vaccum leak that I can think of could be the inlet plenum to the blower. I never took the plenum apart from the blower to make sure magnum powers sealed them together.
Ok, I'm done rambling guys. Can you think of anything else that I am missing or should check? I think I've pretty well covered all the easy dumb possibilities. At this point I am officially lost!!
