Ranger wont start
Hey guys, not much on fords, trying to help Fiancées Dad.
Info: 85 ranger 2.3 L gas.
Problem: Engine running and shut off as if you turned off ignition switch. Tried to restart but wouldn't.
Diagnostics: yellow spark from plugs. fuel coated spark plugs when pulled. suction on exhaust (dollar test - while turning engine over it sucked dollar bill into exhaust pipe instead of blowing it out and away)
Repairs so far: Coil, motorcraft Plugs, Ignition control module, fuel pump relay
So heres where I am now. spark is now blue since coil and ICM were replaced. after replacing plugs it almost started for a brief second but then went back to just turning over. Noticed fuel smell in engine compartment around intake manifold. positive vacuum on hose going to back side of butterfly valve. (thought maybe no air flow). Only other things I can think of is EGR valve, CKP sensor, distributor issue, but none of those would explain heavy fuel smell...or would they??? vacuum lines appear to be intact and non-corroded. Any help or thoughts would be greatly appreciated.
