94 trooper intermittent ly dies
With my 93 trooper 3.2dohc, I have found that it runs extremely rough and will not maintain more than idle if I disconnect the battery terminals. I don't know if this is normal or not, however it runs fine as long as the battery is connected even if the battery is completely dead and won't start a vehicle. Wondering if you have a bad connection at your battery terminal?

You can solve the problem
The tank was spotless when I changed the fuel pump, but I do appreciate your advice. I think I have it narrowed down now to the Camshaft Postion Sensor or the Throttle Position Sensor. I have yet to get the problem to occurr in front of a mechanic is probably the most frustrating factor in this process. A mechanic told me the Throttle Position Sensor is unlikely because it wouldn't do that while driving so I am going to replace the Camshaft sensor and see what happens. The weather got nicer so I have been riding my motorcycle most days now. But hopefully this will be the final thing to fix it right.
Hello,
I have a 1994 Trooper with the 3.2 DOHV engine. About six weeks ago, I was driving when all of a sudden my vehicle died. I pulled over to the side of the road and tried to start it back up. It seemed to be having a fuel issue and was attempting to start as I feathered the gas pedal but continued to keep stalling. About the 5th attempt, it suddenly started up and ran as if the problem had never even happened. About 2 days later the same thing happened. I figured I would change my fuel filter and start there. This didn't cure the problem, as it happened again about 4 days later. Next, I tested my fuel pressure regulator and it tested fine. So my thoughts led me to begin to suspect the fuel pump. I changed the fuel pump and all seemed to have been cured when suddenly after almost 90 miles driven on the new fuel pump, said problem happened again. This time, I had went to the grocery store and when I came out and started the vehicle, it was evident that it was running extremely rough. The gauges on the dash (RPM) were slightly bouncing as the engine began to stall out and the check engine light was flashing some but I could feather the pedal to keep it running (very rough, but running). And like all the other times it seemed to just go away and begin to run correctly again. I have now ordered a new ECM MAIN RELAY as my next venue of guess work. If there is anyone who has dealt with this issue and has any advice as to where to go next if this relay doesn't fix the problem it would be greatly appreciated. I have had the Trooper for just over 3 years now and I really do enjoy driving it. But it has become very frustrating to have no confidence in my ride. It has 162K miles on it. I didn't mention that before.
