should measure 80 Ohms resistance through coil, and you can jumper the pump from there to see if it turns on. Make sure you have power at the relay before you jumper. If power is there, and jumper is in place, then either bad pump, or connector or open circuit between relay and pump.
Remember that the relay will only get a two second run time from the ecm, so you wont find power to the coil unless you are right there when you turn on the key to see it.
Weight Distributing Hitch Systems are designed to increase the capacity of the towing system when added to a Class III, IV or V trailer hitch. The idea is to distribute the load of the trailer evenly to all of the tow vehicle and trailer wheels. To Accomplish this, spring bars are used to absorb load and level the trailer. This offers a more level ride, improved steering and increased braking control, all the while enhancing towing safety.

One guys opinion.

I was wondering if anyone out there would have a online/offline engine manual for my 1991 ISUZU TROOPER 5 SPEED 2.8 LITER. I am looking to change out my transmission, and I need to know the specs of what I'm in for.
Thanks a Bunch....!

HELP! He's dealing with CNX$$!! at the local parts store who have no idea about Isuzu troopers!
Thanks and God bless,

The AC Blower fan became inoperative without blowing fuses. The problem was in the circuitry in which a Resister blew. Part cost is $145! Labor, add 2 hours since it is embedded deep behind the console dash.
Perhaps related? Isolated "burnt bulbs" in right rear brake lamp that don't last more than a dozen illuminations.
Electrical problems surface like water leaks; problems arise at the weakest point in the engineering. Anyone else experience such gremlin mysteries?
Last night after driving home and went to drive into my steep driveway and I noticed that my vehicle would not go into drive (Automatic), it will go into reverse, however if you put it into drive first and will not go into reverse.
Also noticed the electric side mirrors were folding in (malfuntioning)
Is this a ECM problem?
Today I stopped to wash my car at the car wash. After I did so, I jumped on the hiway. About a miles down the freeway, My vehicle stalled. On the side of the freeway, I went thru the process of problem solving the situation. This is what I had done....
First and foremost, I checked the distributor and router for moisture. In doing so, I found no moisture. I then checked all the plug wires, and everything was secure and dry. After that, I went ahead and checked to see if I had blown a fuse. In doing so, nothing was blown. I also checked the fabric wire fuses and rearanged the relays next to the fuses. Then I started to think that there was fule pump problem. I went ahead and put some fuel in the carb from a gas can I always keep for safety purposes. I added not too much and not to little. In craking it over, nothing fired. It just turned over. So then I got thinking, maybe my coil was shot. I went ahead and purchased a new one at the auto store and replaced the old one. To all avail, It still woudn't fire up. All it's doing is turning over. In the end, I ended up having to have it towed home.
So here I am, and I just don't know what to make of it all. When I look back to what I did at the car wash. I didn't open the hood this time to wash down the engine, so I don't know how water could have got anywhere. One thing I did do was spray under the engine and the under carrage. I always do so here in Colorado. Esspecially when the snow and mud collects underneeth.
If there is anyone out there that can help me troublshoot this problem, It would be soooo greatly appreciated....
Thanks a bunch....
Maddy :confuse:
The ignitian module (distributor module), was definately the problem! I replaced and she started up like a charm! THANK YOU so much for your help!!!
Maddy :shades:
My husband is hoping it does not need an new engine!
any notable history about a problem like this?
I think that running a product like Seafoam or Rislone or similar and a couple of frequent oil changes with filters right away may help improve things. That is also a common treatment for this motor. It appears that the oil rings on the pistons get gummed up and stick resulting in less efficient oil wiping and thus increase the oil consumption.
I am sure you will hear other items to check, among them the PCV valve and vacuum hoses, etc. All are good ideas.
Also worth mentioning is that when you change the timing belt , also replace the water pump and pulleys. This is because it is a lot of work to change the belt,and having to go back in to fix the pump or pulley bearings later is just not worth the risk. The factory usually recommends changing the belt at 100,000 miles.
Welcome to the Forum! Hope this helps. Try a search to learn more too!
Remember that, like you, people come to a forum because they are having a problem, so the questions and problems you read about are heavily weighted with negative impressions. Seems like people who own Isuzus and keep them feel they are worth it!!!

If you use another non specified plug (platinum or otherwise) you are almost guarantee to have problems and throw a CEL.
I don't know if you remember me or not. I was the one who left the post I have down below. You gave me advice on replacing my ignitian (distributor) module. When I did so, my Trooper started like a charm. I thought it ok to email you back because you seem very knowledgible in the subject.Though the fix you gave worked, I seem to have the same problem now but a little different.
The other day I started my truck up and went to a friends house. While I was sitting there waiting in my truck, it all of a sudden stopped running. When I tried to restart, it wouldn't do so. It just turned over. After about an hour, I went out to try to start it, and it started right up. When I headed on home, I drove about 5 miles, and than it stalled again. I did go ahead and problem solve everything listed in my previous post below, but nothing worked. I even went ahead and replaced the ignitian (distributor) module with a new one, and still it wouldn't start. Of course once again, I had to have my truck towed home. That next morning, I went out to see if my truck would start, and it started right up. I let my truck run for about a half hour, and it did not stall.
So here. Not sure what to do. I'm afraid to drive my truck because I don't want it to stall again.
If there is any advice you can give, it would be a great help...

I really hope someone can help me. I ran into a situation today with my 1990 Isuzu Trooper 5 speed manual. With a 2.8 liter V6.

I think we have to get back to basics.......is there fuel being delivered to the TBI? Fuel pumps are known to be intermittent as well....but easy to check. Do you hear the pump turn on when you turn the key on? If you don't hear it for a couple seconds and then it shuts off, then it may not be working. You can jumper the pump relay on and then check the connector at the tank to make sure power is getting to the pump as another check. How about spark.....if you pull a plug wire can you see a spark jumping the gap when you crank the engine? Remember that the threaded part of the plug must be grounded for the plug to fire when checking. The coil may need to be checked if you are not getting a spark or the spark is very weak. Check all the grounds on the engine/chassis that you can.. clean them up to eliminate low voltage as a problem. Since the starter cranks I think we can assume the charging system is OK and voltage in battery should be 12 Volts.
Start with these first. Let us know what you find. I am not real familiar with the 2.8 in a Trooper, my experience is from S trucks, but the same ideas apply when troubleshooting.
These are the two most obvious choices to start with. Good luck.
I did problem solve the fule. When my Trooper wouldn't start, I put some fuel manualy in the carb. Still it would not start. It just kept on turning over. I am thinking it is an electrical issue. I did go ahead and replace the coil with a new one. I also wend ahead and changed out the ignitian (distributer) modual with a new one. Still nothing. Of course I checked the basics. Cap and roter, fuses, plug wires. I will go ahead and check the ground connections.

Today I let my Trooper run for a couple hours. I was hoping it would stall so I could try to problem solve more of the issue at hand. It didn't stall though.
Today I came across a friend who said the problem I have might have something to do with the camshaft or crankshaft position sensors. Do you think this could be causing my stalling problems?
Tracy
The reason why I ask is because there is a junk yard near buy that has 7 Isuzu Troopers of my make. I thought I would stop there and pull one of the MAF sensors. I know they're kind of spendy,
