Ford mechanics, I need help!!

[syoungs]

well all the wiring for the fuel pump checks out, couldnt get the truck to exhibit the same symptoms that it was showing before.

I replaced the alternator and battery, charging system checks out perfect now, where it was very finicky before, somtimes charging at 12.x other times right at 14.0v. new alternator is putting out 13.9-14.1
replaced the crank sensor, did not have a chance to test before I replaced, no one here to crank on the engine, and not having long enough test leads, but Ive gambled more then 25$ on a lot worse. Old crank sensor did collect quite a bit of metal shavings on the magnet, and the magnet was recessed about 1/16 of an inch on one side, like it wasn't built plumb.

I also tore through the grounds that the fuel system components use, cleaned them all, they were not terrible, but there was some buildup on them.
i replaced the battery terminals with military style, and crimped new lugs onto all the battery wiring to match. the old terminals looked ok on the outside, but they were pretty hammered after they were removed and inspected closer. also cleaned main battery ground points.

started truck, started easier and faster then it has sense ive owned it. let it idle for 10 min in the shop, all sensors appeared rock steady on the monitor, so I took it outside in the cold and the snow, and let it idle for approx 45 minutes. with no issues showing, i went ahead and road tested it. runs with more power, sounds better in the high rpm band,and showed no issues.

hopefully it is fixed! Dont know if it was the electrical system or the crank sensor that did it, hopefully i am not being fooled by randomness here and it keeps running good!

Nice, hope you got it. Just the other day I fought a toast alternator in my 03' 350 V10,
Grabbed a short term replacement at P.A.W and then the cold snap killed my battery. Think I got it all worked out but kind of strange chain of events the way it showed itself. If not, your shop heated?

It's been about 6 months since I replaced a COP so, that should be coming soon.

 Crank sensor or cam position sensor?

 Hope you got it fixed.

Shop is heated, and getting to be well equiped, your welcome to come over anytime 

It was crankshaft sensor phool.

yall know what "Ford" stands for right?

Yep. First on race day 

[coachcw]

I hope you got it. The crank sensor won't cause the fuel pressure drop though?

[syoungs]

Yeah I agree it wouldn't cause pressure drop, I think cleaning up the electrical system is what fixed the fuel pressure issue. My experience with other Ford modulars has shown a bad charging system plays havoc with these things.
I forgot to mention I also took apart and cleaned every electrical sensor connection that I could find. Maybe that did it...

Or maybe I'm fooled by randomness, and it's just running good at this point, and will fail again. Unfortunately until something else fails, all testing shows everything working as it should be. 

I did buy AAA, cause I don't trust the thing yet! I parked it outside last night, haven't got to the shop today to see how it will react when fully cold. Fingers crossed.

Hope it stays running good for you.
I'm sticking with the grounds. 

[syoungs]

Well trucks home,  ram good on the 11 mile trip back from my shop to my house, hopefully it stays running this way, really like it when it's running good.

Still don't trust it enough to drive it out to work, gonna put some more miles on it around town first.


Now on to the Subaru, and the Ford 6.0 repairs... Gonna be a busy few weeks it seems!

[syoungs]

Well, back to square one.

Trucks on the side of the road with a po191 code....

Guess it's time to drop the $$ on autoenginuity so I can start looking more in depth, I've got a gut feeling that the fuel pump relay may have issues, which is integrated I to the fuse box

go back and look at my reply # 27 and follow it
