Hello again fellas.

My 95 EB F150 (5.8) has an intermittent issue that making me crazy! It's a great running truck that has been well cared for, but the past few days, it just stops running at will. I believe it's an electrical issue because it just cuts out. Sometimes it will start back up in a minute and other times it takes 5-10 minutes. I tried to get to stop running yesterday so I could at least try to find what the problem is and ran great all day. Just worried that it will stop again when I'm away from home.

Any ideas?

 

next time it stops like that get out and kick the bottom of what ever fuel tank your using. lol if it starts right back up your pumps might be working when they want.

 

The fuel pump is new. I replaced it when I bought two new gas tanks last summer. I understand that it could be bad but, when the truck stops running, it stops like right now. No hesitation at all, it just stops. If it was fuel pump related, wouldn't the truck run sluggishly (is that even a word?) before it stopped running?

Also, it has not quit running for days now.

Gotta be something stupid!

 

Two components are prone to this behavior. The symptoms are the same for both.

The TFI module (ICM/ Ignition Module). I believe on your year, located mounted on the driver side wheel well.

This component can easily be removed, then tested by most auto parts stores.

Then the PIP sensor (Stator), mounted inside the distributor. Much more "labor friendly to replace the distributor as a unit. "Cardone" brand has a high "out of the box" failure rate.

Either can fail intermittently in the beginning, but will eventually fail completely. In they're twilight of life. they become temperature sensitive. After some cool down time, will begin to work again, just like nothing happened.

 

Thats kinda what I was thinking too Ymeski. The Ignition Mod was replaced about 5 months ago, but it's easy enough to take out and check. I actually had the dealer replace the distributer and the stator last fall. The stator was causing intermittment issues then, but the truck wasn't stopping, just running rough.

 

Soooo...withholding information are we? (Ever since the Forum outlawed "water boarding")

The KOEO (key On/ Engine Off) Error Scan is designed to help identify causes for "no start" conditions.

PIP will produce a code, but only if you catch it in an intermittent function state.

TFI will not produce a code directly, but can produce a "Spout circuit" error code. Bench testing will rule it out.

I recommend one of these puppy's, available in stores & online: http://www.handsontools.com/Equus-In...ol_p_5574.html
(cable is optional/ not required)

This tool will also help you optimize engine function by identifying conditions that might impede function & efficiency. "Invaluable" would be a good word for it!

Side bar: Possibly a hairline fracture in the distributor cap. If replacing, go w/ a "brass" cap & rotor set. (Once you go "Brass"...you'll never go back!)
