My Mom's 90 2.5 was having intermittent starting issues. It's had new plugs, wires, cap, rotor and coil all within the last month or so. I just replaced the fuel pump along with the tank, but that didn't solve the problem. I then took the ignition control module to autozone to have it tested, and they said it was fine. I put it back in, and now it idles real rough, has no acceleration and nearly stalls coming to a stop. I however think I solved the starting issues by replacing the crank position sensor.
So, I'm wondering could the guy at autozone somehow messed up the ICM when he tested it, and that's causing it to run bad? I assume it's getting fuel because it ran fine for a couple days with the new pump, but I plan on testing the fuel pressure anyway. Also, what kind of fitting do I need for the fuel pressure test port on the 2.5 TBI?
If anyone has some other ideas I'd greatly appreciate it.
One more thing, the previous owner found this part, and thought it came off the Jeep. It's about 2" long and 1" in diameter. Any ideas what it is?
