had the use of a garage for a few hours today so I finally replaced my leaky valve cover gaskets. Got it all buttoned back up and now the fucking thing wont start - It cranks and cranks and sounds like it wants to but won't stay running. Throttle position when cranking makes no change. Fuel pump primes, car cranks but doesn't fire.
I changed:
PCV trifecta
valve cover gaskets
I took off all of the plug wires because they were in my way, but they're all back on in the correct order. 15426378....at least that's from memory. Went through the firing order countless (pun intended..i'm tired) times and it's wired correctly. I was going by whatever was on the fan shroud. To be sure, Ford V8s are numbered 1234 on the p/s bank and 5678 on the d/s bank, yes? a chev cris-crosses if memory serves. I didn't have my books with me when I was working on it so I tried it with a chev firing order just in case, and obviously it did not work...made a nice backfire too.
I obviously had to disconnect all of the manifold vacuum lines but they're all back on where they should be...the vac T, FPR, and MAP sensor all have a source of vacuum.
Plugs/cap/rotor are new as of earlier this week. Ran fine with them for a few days up until this.
The plot thickens: There's a lone purple wire coming from the firewall area that used to run to the area of the ignition coil bracket in front of the motor - I must have nicked it when I was putting things back together because the purple wire is now not attached to anything at the end - Looks as though it belongs in a wiring harness, but it is all by its lonesome. Didn't have the time to trace it back to the source but there's no lone purple wire indicated anywhere in my EVTM that has anything to do with starting/running. My car has an aftermarket remote starter wired in and I always dismissed that lone (non-stock looking) wire as part of the remote system.
readers digest version: My car worked this morning until I replaced valve cover gaskets and PCV system. I had to unplug all of the sensors and actuators needed to do access the valve covers, and as far as I know, everything is back where it should be. Where would you look first? I tried providing as much info as I could but if you need more ask away.
I will be reunited with my car in the morning and will continue troubleshooting at that time. thanks all!
