Details: Ford Ranger w/ 2.3 liter overhead cam, manual trans.

Truck starts and runs fine, but engine goes dead (appears to be fuel starvation) after a mile or two. Let it sit a couple of minutes, and it restarts and then drives fine with no problems until it's allowed to sit for a couple of hours.

Fuel filter & pumps recently replaced, along with a new fuel tank, pick up assembly, etc.

Starting to really scratch my head on this one: Did a complete tune-up: New timing belt, distributor cap & rotor, ignition module, coil, plugs and wires, etc...

I drove it this weekend, and it went dead on me about a mile after I was on the road. Restarted five minutes later and ran fine the rest of the day, under a variety of load conditions.

Letting the truck sit and idle a few minutes before driving it in the morning seems to prevent stall from occuring.

When truck is running, it runs like a sewing machine. But this trouble with it going dead it driving me nuts, since this is my teenage daughter's truck.

So the problem is related to temperature: It occurs during initial warm-up. But for the life of me, I can't think of what could cause the truck to go dead like that; then, restart and run fine all day with no more problems.

Thoughts? Theories? Experiences?

My Tempo used to do that too...but it was the fuel pump...when it was warm outside only...ran without issue all winter and then sporadically did it in wamer weather...had the fuel pump replaced three times...nothing wrong with the pump itself, but a seal goes wonky on them and they can no longer pump gas (not sure if it was the diaphram in the pump or what)...the car would otherwise run great...

Could also be a wonky inertia switch as that was what caused my last issue...it will cut out and the fuel will stop flowing...had one other guy on here with a problem with the inertia switch, but it is not common on Rangers...

It certainly is a frustrating situation...hope you find it soon for both you and your daughter's sake...
 
It appears to have been the intertia fuel pump switch. I read and re-read the description posted here on the Ranger Station site (http://www.therangerstation.com/tech_library/InertiaSwitch.html). His description was almost identical to the symptoms my daughter was seeing with her truck. I checked the interia switch, and the wire connector plug was half melted on one side: clearly evidence that something had gone wrong there, sometime.

I bypassed the intertia switch as a test, and so far, no more problems. I'm ordering a new switch from Ford, and repairing the wiring at the plug. I'm going to give it a few more days before I pronounce it "cured," but I'm very sure at this point that the random problems were a result of intermittent voltage drops caused by a bad intertia switch.
 
:icon_thumby: Good to hear you figured it out...

That was actually a very interesting article about the inertia switch...thanks!
 
A month later, and happy to report: No problems. Hard to believe that a light corrosion inside that switch could cause all those problems.

Awesome Rick!

How much was the switch from Ford, or did you get one from somewhere else?
