Newbie here; newly fostered pristine '86 5-speed, FI and Distributor.
Went from running absolutely fabulously to Absolute Zero. Cranks, but no ignition rough or otherwise.
-Spark at plug: check
-fuel pressure at rail: check
No surprise, eh?
I followed some similar threads here and my situation seems different in that I just replaced the timing belt (fudging the aux pulley until correct) and therefore have confirmed that this is absolutely NOT timing-related. The car was running better than ever for three hours of driving, at which point I parked and decided to do a leak-down and compression test to evaluate the engine (zero leakage and 150-160# across all four).
After completing the leak-down/comp tests, I went to fire it up and nothing but crank. Plugs were all removed during comp-test cranking so the flood-damaged plugs theory doesn't seem to apply.
Is it possible that the FI injectors aren't pulsing? Could there be fuel at the rail and no cylinder-spray? Do Rangers have a relay or fuse that could shut down the injector pulse?
Any ideas very much appreciated.
