trying to work out the last few bugs in my trooper. its a '92 3.2L DOHC auto 4x4. when i bought it, it was completely empty of gas, so i figured that was the reason it took a few seconds to start up. after getting it home and filled up, its still having the problem. so, heres what ive gathered so far:
-when trying to start, it WILL start, just takes 5-10 seconds.
-once running, white smoke comes from the exhaust, as it warms up the smoke disappears(previous owner removed the cat, could be the problem)
-has no problem cranking, new battery, alternator is good as well
-once started, there is a small hint of a gas smell for maybe 15 seconds(not sure if this is a gas leak, or just extra gas from trying to crank it over?)
-last weekend on its first offroad test/drive, made it out to our trails fine. once there, turned it off, then maybe 5 minutes later tried to go run some trails with friends. wouldnt start. tried cranking again, with the hood up so my friend could watch, and he said he saw sparks. upon inspection, the positive battery connector had melted partially and was dripping onto the battery.
-traced positive wire/positive electrical accessory wires back to fuse box, and found both of them cut in the same place, with corrosion in them.(im assuming this is from when the previous owner wrecked it, something must have been pushed into them.
i dug out as much of the corrosion as i could with a knife, installed a new battery terminal connector, and she started right up, better then before. got her home, tried starting her later, and it was hard to start again.
so, im thinking the corrosion is creating too much resistance, cause the battery terminal connector to heat up, hence the melting. the extra resistance would also make it difficult to start. planning on replacing both positive wires this weekend with new ones. as for the smoke, is this just because of the cat being removed, or something else like a head gasket?
thoughts? kinda stuck on this one. not sure where to start?
