Fuel filter? There's also a filter on the suction intake inside the gas tank, it can get plugged up. I'd definitely try the filter if you haven't. Good luck. Have you checked the fuel psi coming from the tank? If it's fuel injection, it should be pretty high, 55 - 60 psi. Let me know if I can help.

1988 ford ranger 2.9 ltr engine stalls while driving , restarts in a few minutes usually


There are several possibilities, but based on how you described the symptoms I suggest a profile igniton pickup. On these systems the failure usually begins as dropping a cylinder occasionally,like a misfire,mostly during high underhood temperatures,will manifest into stalling and finally into a stall with no resart condition. Symptoms are most likely to occur in summer. The pickup is inside the distributor and the distributor must be disassembled to install it,the trickiest part being the removal and installation of the distributor drive gear. They are iron and easily broken. The simplest solution is another distributor. The ignition modules typically do not fail in this manner,but this is classic for the pickup coil. A code for loss of pip signal should be present, it is possible for a code to not be present,though very unlikely. Having worked on these systems for years this would be my first area of diagnosis.

Fuel caps have breather holes in them - once clogged the fuel tank is sucked vacuum and the engine stalls. Check the fuel tank cap for clogged breather holes.

1988 ford ranger ( 4 cyl ) Fuel pump kicks on, motor starts and runs approx. 5 to10 min. and dies. Turn key back on and can't here fuel pump.


It sounds like your fuel pump is overheating. Once it gets too hot the bearings swell and the pump locks up. When it cools, they contract and the pump works again. It is also possible the fuel pump relay is having a thermal failure. You can determine this by hooking a voltmeter into the fuel pump supply wire and keep it where you can see it while it is running. If the voltage goes down and then the truck stalls, it would be the relay, if the voltage goes down after the truck stalls, it would be the fuel pump. Since the pump is only running when the engine is running, once the engine dies it'll turn off the fuel pump so it is important to pay attention to what happens first.

I got a 1990 ford ranger 2.9 v6 its running very crappy


Fluctuating an high RPMs sounds like a leaking or missing vaccume hose to me, I had simmilar problem found open hole with hose off, replaced it now the RPMs are under 1000 again.
As for the stalling I also am having a simmilar problem, and am finding air in the fuel rail, I suspect the fuel pump is going.
I cant go more than a mile without problems.
