Replying to: bobparker (Jan 17, 2008 4:03 pm) As you are learning, electrical problems seem to top the list on any forum but maybe even more on the Isuzu's! I don't have your model truck, but.......... Very often the alternator is the culprit....when it goes bad it wreaks havoc on the rest of the system. Try just unhooking it and see if you get any different result. Cleaning the grounds is also another must do, and IIRC there is a fuse or link in the circuit in the eng. compt. Also, there may be a voltage regulator on the firewall, it depends on the model I believe, Under hood, center, rear engine area, mounted on upper firewall. I hope this helps. Good luck. |

I have a '94 Trooper, original owner, 140+K miles. I've had 4+ starters and alternators, automatic trans, but all in all a pretty good car. But like a fool, I love it. I' ve had several local mechanics work on it, but have never really been satisfied. In all cases they made good on the work (the valve cover gasket job took two tries and a week and $600 to do right) Any way the brakes were done at the 60K service around 2000. So at 140K I'm thinking maybe time to check. Pulled the wheels and Holy cow, over half the pads left. But since I had the whells off I did the pads anyway.When I got to the left rear, the last one, the inboard pad was GONE and the rotor slightly scored. In taking off the caliper, the bottom bolt snapped,leaving about an inch and a half of the nonthreaded post in the outboard part of the pad frame. Now this 60K brake job was done at the dealer, remember? So calling around looking for the part Ifind out the two caliper mount bolts are different diameters! Well I guess dumb luck and a 50/50 chance let me get it right on all the other wheels. Not having the ability to replace the pad frame and bolts at the time I put it back together the way it was, figuring it worked for 80K miles, I'll do it next weekend. Well, then I get a high pitched squeak from that wheel at a crawl. So, I go to take that bolt out and it snaps again! Now I have the bolt head,an inch of thread and an inch of post in my hand and the rest of it in the frame. Meanwhile I'm driving the car, it stops fine and I'll get around to it soon. But what still gets me is that the problem started with the "dealer brake job" and that except for that right rear wheel,after stopping a 4400 pound car for 80K miles it didn't need a brake job ??? What kind of pads were those.

When I bought my Trooper used, it had aftermarket pads. They had worn unevenly due to no reason I could find. I cleaned and lubed the caliper pins and knock on wood have had good results. For some reason,the design of the caliper has two different style pins, but I have never seen that before or since. They are some kind of dust seal (so I am told). The calipers are prone to getting sticky if you see much salt air or snow/mud/salty road conditions, so cleaning them up and/or replacing them seems to be common. Hope this helps. Good luck. |

I have an after-market Pioneer DEH-P4800MP stereo deck, (2) after-market JVC front 6.5" speakers, and had (2) after-market Pioneer rear 5.25" speakers installed in my Trooper last night. Upon completion, things sounded great! Well... I got down the road a few feet and adjusted one bass setting and all the music stopped. My CD player was still working, however there was absolutely nothing coming from my speakers. My assumption is that I have blown a fuse. Can anyone help me locate the fuse so that I can check it? Thanks.

I have a 2002 Trooper and I can't remove the spark plug boot. Help please. I don't want to break it by force.

Why does my '02 Trooper "drink up" so much oil? I never see any oil leakage on the engine. How can I correct it. What type of oil do you suggest?

Replying to: jake1216 (Feb 25, 2008 10:29 pm) If you get the coil pack off the top and the boot is stuck on the plug...try using compressed air, even one of those little jobs you can keep in the trunk. A hand air pump might even work. Use one of the little tapered adapters if you have one and shoot a little air down the center hole. The boot should pop right off. I did that on my one stuck one when I changed plugs a couple of years ago. One little burst of air from the compressor and it popped right off. Bill '00 Trooper in Memphis
