#47 of 83 Electrical Issues
Sep 03, 2011 (12:11 pm)
I have a 2000 Isuzu Trooper. I have had continuous electrical problems. I have replaced the following components. control Unit, mass air flow sensor, throttle position sensor and the starter. I'll start it up and about 10 minutes into a ride, the RPM does not go below 1,000 RPM. Another 5 to 10 minutes of riding, when I come to a stop sign, the engines shuts down or it just surges. Example, I place it in neutral, the engines idles from 1,000 to 1,500 continuously.
Sometimes when it shuts off at a stop sign, it will start however, I have a Check Engine light and a Reduced Power light. When I get it back home and try starting it the next day, it starts without any issues and none of the warning lights are visible????
#48 of 83 Gauge lights, headlights, and tail lights went out

i was driving in the evening and my gauge lights, headlights, and running lights went out at the same time. My blinkers and brake lights still function. I can also hold my brights on. Please help.

I have a '94 Trooper 5-speed that blows the fuse for the turn signal and back-up lights. Sometimes it will blow soon after replacing it or it may work for several days. There are no obvious breaks in any of the visible wiring. Should I now suspect the turn signal switch or should I continue to look for a wiring short elsewhere? Any suggestions would be greatly appreciated!

Have you checked the fuse block for blown fuses. I have a headlight problem but all my gauges work fine. Fuses would be my first to check. If you need to replace a fuse, and it blows again, you have a short somewhere.

I would suspect the turn signal switch first, simply because of the wear and tear issue. If you can get ahold of a wiring manual, you might be able to see what circuits are linked. A turn signal r/r would be an easy fix.

i own a 2001 trooper 3.5 ltr. manual,and trust me i have had all the same issues as everyone else that owns one..have your mechanic check this out..
i used to have and issue with my vehicle check engine light coming on and the vehicle going into "limp mode" or reduced power light.. i had my first mechanic check the engine codes and they all came back to the throttle body..i had the throttle body replaced,egr,and had bg products blown through the intake system..got the truck back and a week later the same issue appeared after costing me about $1200 parts and labor..after taking my vehicle back to the same mech. 3 times i had a backyard mech. look at my vehicle and he stated that there are two wires in the harness connected to the throttle body,coming from the ecu that short out and
he repinned the connecter at the throttle body because the connectors inside the harness were moving around inside the connector loosing connectivity also..the mech reran two wires from the harness outside the
harness bundle straight to the connection at the ecu and i have not had that issue since...in my opinion i would check this first before spending time and money chasing your tail...

I have the answer to your problem. I have a 98 trooper I bought new. I am an aircraft mechanic and I had the same problem you have now. Many other trooper drivers will experience this problem too. Your answer is to take the allen head screws from the sensor which goes into the air intake of your engine. When you open your hood follow your air filter inlet from the air cleaner box to where the intake goes into the engine. Right there you will see a sensor with a plug on it. It has two allen head screws. remove that sensor and spray it off with electrical cleaner. You will find it has a bunch of black soot on it. If you spray it off with cleaner, dry it and reinstall it you will have your trooper back in good shape I promise....Kevin

Check your wiring connections to the starter first. You may have a loose wire. If all the wires are tight, you may have a fusible link in the circuit or there may be a short in the wiring. The bottom line is there is a bad connection somewhere. When you charge the circuit it breaks, once it heats up. Just my thoughts. Let me know how it goes!
