Does the '89 Isuzu Trooper II have a gas tank


Depending on how good the guage is, when the yellow light comes on telling you that your fuel is low, you have approx 2 gallon left in the tank. It is never good to run on a tank that low due to heat buildup of the pump which causes pump failure. The gas acts as a coolant for the pump.

1990 isuzu trooper will not start in cold weather


Well, could be many things, but first and easiest, check the dist. cap and rotor, and all the plug connections. Any moisture will freeze and short out the ignition system. Also change the fuel filter. If you get the slightest moisture in the fuel it will lock up the filter when the water freezes. Could be a relay, probably "engine relay" that sticks when it gets too cold.

Some starting points I hope.
