The issue I've been having is getting worse. I used to be able to let it sit for about 20 minutes and it would crank back up. Now it's pretty much done for when it quits.
Here is what I posted aon another forum weeks ago when it first started doing it...
quote:OK my truck started this a few weeks ago. I was driving along and it just dies cold, didnt shake, spit, sputter.. nothing just dies. I coast over to the side of the road and it takes like 2 tries and it fires up, drive it home and let it set over night. Get up the next day and drive all over town and then I'm just about home and it does it again. Try to crank it and it runs for a few seconds and then dies again. Let it set for a couple minutes and after about 5 times trying to crank it it fires up and I drive it on home.
After this I let it set for about a week, it starts fine every time I try it. So I start driving it again and it runs great for a few days. Now it does this thing where I'm just cruisin down the road with normal pressure on the gas and its like it jerks, and stalls for a few seconds but the engine comes back on after those few seconds and it runs fine for a little while. Most of the time it runs fine now but after it warms up it will do this latest thing a few times over the course of a 20 or 30 mile trip. Yesterday it died on me in town and it took about 15 minutes to get it started. It ran a once or twice for about 5 seconds in that time.
I changed the filter last fall, I have a new one to put on now, but I really dont think thats the issue. My uncle who is a mechanic told me it sounds like fuel pump issues, I tend to agree but hoping it could be something small like a regulator or throttle sensor maybe. It's a 96 ext. cab short bed 4x4 with two tanks, do these things have pumps in both tanks or just one? It doesnt have one on the frame rail and switching back and forth between the tanks makes no difference when its having one of the no start issues. You can hear the pump kick on when you turn the key on too...
I'm just not sure what to replace first as money is tight. It threw a code a while ago but went off in the parking lot of advance auto when I was gonna have it read...
I also done a tune up on it about 30,000 miles ago... (plugs, wires, dist. cap, rotor button, pcv valve and also replaced the DPFE on the egr vavle)
Help please!
I have replaced... Fuel relay, ignition coil, crank shaft position sensor and the ignition control module. The fuel pump kicks on and sounds fine and the fuel filter isnt that old.
Every time I replaced something it ran great for a day or two and then it was right back to the same old crap.
I took it down last week and had the codes read... 2 showed up....
P0320 - Ignition/Distributor Engine Speed Input Circuit Malfunction
P0171 - Fuel Trim System Lean (Bank 1)
I'm pretty much at a loss here. It's a 96 F-150 4x4 with the 5.8.
It runs AWESOME when i can get it fired up, full power on tap and it idles perfect... So I dont think it is a vacuum leak but I dunno.
Help me please!
