I was installing a power antenna and forgot to disconnect the negative battery cable. When I was hooking up to the power lead to the radio, it dropped from my hand and fell on the radio. This produced a sizable spark and the Trooper would not start after that. I had it towed to my mechanic who replaced the gas pedal sensor, the throttle position sensor and the crankshaft position sensor with no success.
As stated before, before my mechanic replaced the other parts, I sent the ECU to a company in Jacksonville, FL. They returned it without telling me it was unrepairable. In the meantime, this accounted for the part changes. Only when I called them to tell them the ECU was not working did they tell me they are refunding my money, and the ECU was unrepairable. So, I can't blame my mechanic. I got burned because of the ECU repair shop's negligence.
