Question about 1989 Jeep Comanche
I have an 89 Jeep Comanche, 6 cyl. 5 speed. The mechanic said the fuel pump was going out because it was hesitating really bad when you stepped on the accelerator. I replaced the fuel pump and it ran great for one day. The next morning I went to start it and it just cranked and cranked but wouldn't start. I took the fuel pump out and replaced it again. (The old pump worked fine at the auto parts store when the manager hooked it up to a battery). Again, it started right up and ran great for a day. The next morning it wouldn't start. I am wondering if it is something electrical. Any ideas?
On mine the fuel pump power wire retainer (the plastic piece holding it to truck)broke. wire touched driveshaft fuel pump did what you were saying at first. then shorted the lead to fuel pump inside the fuel tank. pump didn't work at all after that.shorted to fuel pump mounting frame. has done it 3 times no fire yet .just freaks me out a wire melting inside the gas tank.(the lowest gauge wire in the circuit) what i'm saying is the power wire to the fuel pump could be damaged on what the fuel pump is mounted to(the wire outside the tank)
