#55 of 74 93 Trooper headlights go on by themselves by mstout Aug 25, 2008 (8:33 am)
I was wondering why in the mornings my Trooper's battery was dead. Eventually I saw that at any given time, the headlights mysteriously would go on by themselves and are unable to be turned off by the interior switch or even by pulling the lighting relay out of the fuse box in the engine compartment. I totally disconnected the alarm to eliminate doubt. As it is now, I have to disconnect the battery every time I park it. Anyone with this same problem or any suggestions? Thanks. Mike
#56 of 74 weird start problem by nqlblq Oct 02, 2008 (10:33 am)
So I have an 89 Trooper RS (the 2-door).    I was driving it home and all of the sudden all of the dummy lights came on. Gas, Brake, Battery, O2. The car kept running with all of the lights on.    When I got home, I turned off the car and tried to turn it back on and it would start up and die immediately. I can get it to stay on if I leave the key in the "start" position in the ignition but once I let it back to "On" it dies.    After I replaced the entire fuel system (except the pump which is a year old), the Air Mass Overflow, and the fuel pump relay and the main engine relay - it still wouldn't start.    That when I looked at the fuse box. I took out the main engine relay (big blue one on the outside of the fuse box) and it fired up. It started and ran really rough. All of the lights were off and I could drive it around - barely.    When you put the MER back in, the lights come back on and when I turn it off, it won't restart.    I'm basically out of ideas here. Anyone run into a similar problem? Or have any ideas about what else I should replace Replies to this message: atfdmike (Oct 03, 2008 2:19 am)

Replying to: nqlblq (Oct 02, 2008 10:33 am) I don't have the first gen Trooper, BUT I do have some experience with the problem you describe. I would check the alternator. It is often the root cause of a number or problems you describe when it goes bad. At least have it checked before investing more money, I am thinking when you turn key to start it takes the alternator out of the circuit, like removing the fuse, and the engine runs poorly on battery power alone. Your battery may be close to too low to even run the engine by now. One guys opinion.

atfdmike had it right - alternator.   Ran through the entire engine looking for any and all problems and found that the alt was bad. Went to napa dropped a hundred bucks and bam - starts right up.   thanks mike.
#60 of 74 89 Isuzu trooper 2.6 4cyl starting problem by jeepers97367 Nov 24, 2008 (8:51 am)
starts right up in the morning, but if you go down the road a little ways then shut it off and try to restart it smells like gas real bad and wont start. sometimes it will if you push the pedal to the floor and crank on it.

#62 of 74 89 troop 4cyl problems starting. by mywar Mar 13, 2009 (7:03 pm)
HI- My trooper has a hard time staying running when it is cold. Initially to get the car started, I have to hold the key in the start position and give it gas. If I can get the engine to rev up to 5k rpms then the car will idle and stay running like nothing is wrong. Otherwise the engine starts and runs for a second and then dies. Again I must rev the engine to 5k rpms during startup and after that the car idles normally and runs. Before the car dies, all warning lights flicker and there is no heat/ac air. I have replaced the alternator and starter in within the last year. Any help or suggestions would be much appreciated. thanks Replies to this message: atfdmike (May 05, 2009 2:00 am)
#63 of 74 96 trooper 3.2 starter by 03Bob May 04, 2009 (5:38 pm)
The dreaded remove & replace starter hit me today. This forum has been very helpful in sorting out what needs to be done to remove the starter. I thought I would be in for the manifold battle but found a trick(on this forum) with sending it forward. But wait.... I was able to sneak the starter past the exhaust pipe by getting the starter in just the right attitude. I did have to drop the crossmember, 4 bolts, but compared to dropping the y pipe....priceless. So passing this along to add another way to R&R the starter. I believe this is a classic case of Divine Intervention.   additional: starter was tested by jumper cable to starter stud. No joy(or motor spin) conclude starter is used up.

Replying to: mywar (Mar 13, 2009 7:03 pm) I would start by checking connections on alternator, and grounds from engine to chassis. It really does sound like an alternator problem, especially when the warning lights and blower don't work right. Isuzu has a funny wiring for the alt/charging system, and it is not unusual for an alt to test OK but still not work properly with the system. I would start with the above and then move on to checking the alt and connections by cleaning and re tightening before finally assuming the alt is bad again. HTH One guys opinion.
