#63 of 108 96 trooper 3.2 starter by 03Bob

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.

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.

I have a 94 trooper. that I am having a hard time with. it will start on starting fluid. but after the starting fluid runs out it will still run if you pump the pedal. it runs really bad after the starting fluid runs out and it pops in the intake.I have changed the fuel pump and the map senser. I have 40lbs in the fuel rail.

#68 of 108 Battery dies overnight by willbee

Aug 03, 2009 (10:35 am)

I have a 88 Trooper 11 2.6 L and had to put a new battery in her to start. Than to my surprise the next moring she would not start. Charged up the new battery and than she started up. Alternator is putting out when engine is running. Now I have to disconect battery cable at night so I can start up the next day. I must have a short somewhere in the vehicle causing this problem. Can anybody help me solve this electrical problem. Thanks

#69 of 108 Trooper has weird starting problem by jw_downtime

Sep 17, 2009 (9:06 am)

Vehicle: 2001 Trooper Limited 4WD
 
130,000 miles
 
The Problem:
 
The first time the engine is run, it starts normally and runs smoothly for about 5~10 seconds. Then the RPM drops to a few hundred and the engine chokes, coughs, backfires through the air intake (not the exhaust). It often stalls and must be restarted. After about 5 minutes of the rough idling it will smooth out and run fine for the rest of the day. I will often get a P0300 error code (engine misfire) an occasional P0101 (MAF) error and P0440 (EVAP) code. These are never together (only 1 code stored), and do not always occur after the first starting (the P0300 being the exception) .
 
The engine trouble light will often “flash” after the above without any trouble code found, and the engine performance is sluggish. Usually the check engine light will go off and not return if I stop and restart the engine. After that the engine runs fine.
 
One additional symptom occurs (rarely) in that if I have been driving at highway speed for a lengthy time and stop – the engine stalls. But, it starts right up.
 
The engine burns oil (at the “normal”, for the Trooper engine - 1qt/1000 miles) and there is never any Blue smoke from the exhaust. It acts like fouling, except it start normally them the choking starts. I also thought about a clogged fuel filter or fuel pump, but that too would be a continuous problem.
 
Have you seen this behavior before? It does not seem to be getting worse, but with the cold weather it may become so.

#71 of 108 '90 Trooper won't start on incline by tiptopsu

Oct 21, 2009 (4:18 pm)

I am the new owner of a 90 Trooper, carburated V6, manual trans. Getting used to the clutch, I let it die on an incline on several occasions. It refuses to start again on the incline.
 Coasted back down to flat ground and it took several minutes before starting.
 What would be causing this?? Thanks..

my 1998, 3.0 citation td lwb, when i start it up from cold, after 10-20 seconds the revs drop very low and smoke bellows out of the exhaust and this lasts for approx 10-15 seconds, then it revs up again and the smoke clears and its fine thereafter. Has anybody else had this problem ? many thanks
