1989 Isuzu Trooper Won't Start

Finally got on.. Yes, I wrote a long answer and ws unable to "copy" it so it is lost... Ok, the oil level is easially missread so triple wipe and check for clean line. If the level is too low or the sensor is broke it won't allow the fuel pump to turn on... It is a great safty mechanism but a real pain if you've gon through the pain in the Donkey to remove the gasse tank and replace fuel pump. always, find connector on right rear wheel well (square plug) two wires, red and black... Hot wire it and see if it works. BEFORE REPLACING pain in the Donkey fuel pump.

Also check all vacume hoses, especially the three block right under the intake manifold and the large one under the intake manifold.. you can't see it without a mirror. Another pain in the Donkey!! Still doesn't work? I onoly think it might be the timing belt has jumped or broken.. another pain in the Donkey!! Replace everything while your in there!! and the ac can be moved out of the way without discharging. Compressor and air wrench (rachet type ) is essential for working on this car, along with lots of extention, extentions and odd sized box end wrenches!!! I love this car but it is a pain to work on... What were they thinking?? Like I've thought it would be so simple to have an access pannel for the fuel pump!!!!! I could go on. Also I have heard that there are two temp sending units and one is used by the computer, if it goes bad is screws things up badly and you'll flood the car out when it is hot and thinks it is cold. All the best.. Colin Finally got on.. Yes, I wrote a long answer and ws unable to "copy" it so it is lost... Ok, the oil level is easially missread so triple wipe and check for clean line.
