Help! I have a 1986 Jeep Cherokee Pioneer 4 cyl 2.5l 5 speed manual. I can start the engine and drive for a while, then when the engine warms up, it stalls and won't start up until the car cools down for at least 30 minutes.
This problem started with the car not starting if I stopped the car after driving a short distance (like when I got gas then couldn't get it started again). It cranks but won't catch. Now it will stall while I'm driving. Three times I've slowed down or come to a stop and when I hit the gas, nothing. It sputters and backfires from the engine like it's not getting enough or any gas. Both times I was able to get it into a parking lot and let it cool down.
I've replaced the spark plugs, wires, distributor cap, rotor, MAP sensor, and TPS.
The fuel pump comes on, but I think it may be staying on as I drive (sounds kind of like a jet engine).
I have purchased a new CPS, a fuel pump and filter but haven't attempted to replace these yet. I replaced the easy to get to stuff first.
So...does anyone have a guess as to what it wrong? I've been reading that the CPS can cause a bunch of problems but it looks like getting to it is a challenge. But so does the fuel pump.
Any suggestions are appreciated! I love this Jeep and want it to run well
