I have the 2.6L Trooper. It has basically sat for the last few years, driven sporadically. I've driven it last about a month ago then parked it until now. I am stumped with the following while trying to start it;
Truck would crank but not start. Found the fuel pump was not running. I looked in the fuse box and checked all the fuses, then swapped out the engine relay with the fuel pump relay, I then heard the fuel pump start working. I bought a new fuel pump relay, plugged it in, cranked the key....nothing. Fuel pump not working again. I then pulled the engine relay out with the key turned and lo and behold the fuel pump kicked in and I could start the vehicle. I bought a new engine relay, plugged it in, fuel pump does not work. Only by removing the engine relay entirely and turning the key will the fuel pump come on. If I do this and then insert the relay, it cuts out again. I left the key turned to power everything and then played around with the engine relay, when it made contact I could hear a click from what turns out to be another relay in behind the headlight. I pulled that and cleaned everything but it made no difference. I am at a loss with this.
I basically want to get this thing going so I can sell it and not sink a whole lot of money in it to do so.
