| Thanks. Our warranty is 100 000 miles so we still should be covered. Isuzu replaced the head about a year ago because of a recall. It was warped. We had no idea there was a problem with Isuzu engines til now. Thanks again. | |

I have a 1996 Trooper with the gear shift type of 4 wheel drive (no electronic buttons on the dash). When shifting into 4 wheel drive (either hi or lo) everything is fine if I shift into 4WD when the vehicle is cold. I can do this when I first start up, and all is OK. If the Trooper has been driven and is warm, the 4WD will not engage. The dash light (4WD indicator) works fine and when engaged it lights up (green) and when not engaged it is off. When it is in 4WD the system works great. Unfortunately, this is a problem, as I drive the Trooper a couple of hours from home to a mountain cabin, at which point I need the 4WD to navigate the road. I had to let it sit at the base of the mountain, and get a ride with a buddy up the hill. Came back the next morning when the car was cold, and 4WD worked! I have tried this a number of times with the same result - warm - no 4WD, cold - all OK. Any help would be greatly appreciated. Thanks.

The latest: I believe I have found the trouble. On the VSV there are 2 switches, blue & gray. remember the 4WD works when cold, as the engine warms, the gray switch is closest to the oil pan. As heat radiates, it warms the gray switch. I got brave and took it completely apart. The metal slug inside the plastic housing was binding in the bottom of the bore. I used a drill to clean the sides as much as possible. still binding. Calipers measured the slug and I reduced the diameter about .010". I used a collet on my milling machine to hold the part while gently filing and scotch briting the part. reassembled, applied power and it now clicks when power is applied. next step is reintall on trooper. I am running on the premise that if the switch will not function w/ power, the vacuum can't get to the right place. After lunch, I will find out. |

Replying to: belaircarguy (Feb 14, 2009 6:44 am) I saw the part on Ebay, $179. I did not check with a dealer. The 4WD engages as it should, hot or cold. While I was at it, I figured this would also be a good time to drain & refill the differentials and the TOD(torque on demand) (thats where the fork slides a gear over the 2 shafts and makes it drive the front wheels) Switched to synthetic oil as we get some cold days here in the Northeast. Responds better when shifted into 4WD. Not to bore you w/ details but.... the 4WD lever mechanically engages the transfer case and apparently it also sends a signal to the VSV(vacuum switch valve) that moves a diaphragm/shaft/fork assembly, routing the vacuum to the proper side to move that fork in/out of 4WD. I did purchase the shop manual for this rig, hence the long explaination. There you have it. Glad your trooper works too. |

Yup, same old problem. After the pain in the Donkey replacement of fuel pump which was not needed!!! But in this case it was a good thing because the filter had fallen off.... but I have hot wired it, which now I know is the FIRST thing to do, and it works fine. So I was sure it was the oil level and yes it was 2 quarts low, but now it is at full and still pump will not work except when starter is engaged, so it starts and then cuts off. Now, I can't find my manual and don't remember where the oil sensor that sends the signal to allow the pump to work. it is a 1998 2.8 and I love it!! I even swaped engines with out a manual, Yea, So this is such a minor problem and very frustrating. I am about to hot wire direct to the ignition but want to know if it will hurt anything. Does the pump work all the time ? Does it have a pressure shut off? From what i can tell it simplu has a pressure relief valve on top of the pump but I don't want to burn out the motor since it is such a pain in the Donkey to drop the gas tank!! I think the nextrt time I'm going to cut an make an access pannel. I truely think it will take less time. I'm also pissed because the two bolts on the same side that hold the protective cover sheared off.. guess I have to weld something together. Well, If anyone has a manual for this year or knows about the pump electrical system please give details or email me with them at miracore rcn.com Thanks and Blessing to all.

| Recently had the transmission slip issues and took it to a transmission place who told me the transmission was full or fluid and when the opened up the pan there was a ton of metal. He rebuilt my transmission replacing a pump and other necessary parts. Took it home where the temperature light went on. I stopped the car it was dead. They shop took another look and said it was a shift on demand issue, he repaired that. Brought it home where it ran like a new car for 24 hours then began to feel sluggish again. Now when I shut the car off the parking lights stay on if I lock it. I am not mechanical in any sense of the word!! Does this sound familiar?? | |
