See my profile, not great w/ newer stuff, do attempt repairs on them, but I do alot of research before I jump in. But take him to Autozone or Advance Auto. FREE CODING. FREE ADVICE. FREE SHOW ME WHERE AND WHAT TO DO. PARTS NOT FREE. Some rigs will STORE a code even if light does not stay on. Have 2 books on codes, don't know years they go up to or might still apply to. If free coding gets you no where, or other inputs here or somewhere else is NO-GO. I will attempt to research possibilities. Better w/ real JEEPs. Wadda you think. Love, Turddog

Crank up runs fine for twenty minutes or so. Then will start until quits. Both check engine light and engine light will come on. Will do while driving or just at idle. Then wait an hour or so. Can get in drive back home.

When it stalls do you have spark? Check this guide toward the bottom to see what I am talking about.

Please let us know what happens.

Will still start and idle. Just cannot give any gas. Or stall then can crank couple more times before will not any more. If get underneath and pull fuel line off put back on it will start again. But will not go to far and do it again. I suppose spark would be issue?

Yes is sounds ignition related. These trucks had a problem with the ignition module on the side of the distributor I would also do the pick up coil as well.

Check out the diagrams (below).

With the ignition key on does the coil have power on the positive side?

When the engine cranks over the negative side of the coil should flash.

Why doesn't the check light work when you run the codes? It just stays on, does not flash.

RETRIEVING CODES

Tips Click a link to view tip
Tip: ABS CONNECTOR - 1987 F150
Tech1
To obtain stored trouble code, momentarily ground diagnostic connector and record number of times light flashes. See Fig. 2. DO NOT turn ignition off before grounding connector or code will be lost.
Only the first code stored will appear until that problem is corrected.

I have looked every where on this truck but have not found it. The only thing I have found is a connector in my glove box, but it doesn't fit my code readers connector. I am using a Innova 3120 code reader that reads both OBD I and OBD II.

If you have a paper clip and test light I can tell you how to hook them up and count the blinks on the test light to retrieve the codes.

I have a 01 f150 4.2 2x2 5-speed man. About 6 months ago my engine light came on. The code came up EGR pressure and bank 2 fuel too lean. I changed the EGR valve, sensor and solenoid, and I also cleaned out the tube from the exhuast to the EGR valve. A day after clearing the code the light came back on. To make a long story short i'll just tell you what I replaced through the 6 month period; Coil pack, maf sensor, spark plugs & wires, and both O2 sensors. After changing all these parts, my light is still coming on with the same code a day or two after I clear it. I am at a loss. Can you please help.
