The intake air temperature sensor can be found in the air intake duct, or threaded into the intake manifold depending on which engine you have.

SOURCE: 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.

My 1990 isuzu trooper was driven to town when it started to heat up and miss a lot. No power on acceleration. Shop took compression test. # 1 piston 150 # 2 50 # 3-0- # 4.-0- I had the auto shop replace...


replacing the head gasket solved one problem.
But, you have a leakage problem with oil and/or antifreeze now.
The head gasket could be failing again, or you have a cracked block or cylinder head.

Take it back to where it was worked on and say that you want it fixed, please.

good luck on this.

Where is the diagnostic plug to get codes from check engine light


The 1990 Isuzu Trooper with a 2.8L GM engine, the diagnostic connector is located directly beneath the coin try in the front of your center console!!
Along with the typical OBD connector is two wires with a spade connector on each, one female and one male. Connect the two wires to display the diagnostic codes on your check engine lamp on the instrument cluster panel.
As for finding out your codes meanings, go to your nearest public library and locate a 1990 Trooper service manual.
