#11528 of 11966 engine won't run
May 31, 2007 (2:19 pm)
I am the owner of a 1999 Isuzu Trooper (gasoline) that had been abused. I purchased it consuming about 1 quart of oil avery two weeks.
One day driving home from WalMart the engine blew (Crankshaft snapped in two). My father just finished rebuilding the engine and we can't get her tu run.
Fuel pressure is correct, IAC, MAS, TPS all check out. We have nice blue spark, plenty of fuel coming out of the injectors, no ECM codes other than: [SS1 and SS2 Open]. What do these codes mean? Other than that, the timing is to spec, and everything checks out!!

Your symptoms are not entirely indicative of a dirty range sensor, but a harsh 2-3 shift is one major symptom. When you shift the truck, check the lighted indicator in the dashboard to see if it matches up with the shifter position in the console. If the lights do not correlate to the actual positon or if they jump around randomly, you have a range sensor malfunction. It is easily cleaned in about an hour and you do not have to drop the tranny or anything.

Still won't run. Tried adjusting the timing in case a tooth was off or something. It wasn't. Compression is at 195.
The car would run with an engine that had a snapped Crankshaft for pete's sake!
Anyone have any ideas???
NEED HELP!!!! NEED THE CAR!!!!!
#11531 of 11966 Overhead lamp wiring

Do all Troopers come pre-wired for the overhead map lights at the top of the windshield??? Anyone have any insight into this, or data to enlighten??

Unfortunately, I think unused wiring is not in there, I would like very much to be wrong, but based on trying to save my power mirrors from a totaled 1995 Trooper and put them on my 2001 Trooper, I think there were at least two wire harnesses available in the factory, one for the 'S' model and one for the 'LS' model and maybe more.

Looking at 1994 tropper been sitting 4 years since friends husband died. He dove it every day. 133,000 miles V6 oil was black started right up when jumped off didn't smoke. Motor clicked real bad for about 15 mins drove lifter quieted down she says it never done that before. Oil pressure about 40 to 55psi driving after getting hot with old oil at idle barley registers any oil prssure. tap gas goes back up to 30 to 55 psi. believe oil change will fix this. Trans fluid nice and red. drove real nice 4wd. Can buy it for 1500 bucks. looks like new. I know nothing of isuzus but have always admired from a distance. Is it worth it. Do these have many problems. How many miles are these good for. Thanks

IF it were me, I would ask to be allowed to do an oil change and make sure the oil is topped off with a viscosity 10W30 that I am familiar with. Then run the engine by driving around a half hour at least. While driving try and notice the oil pressure and other things that might be of interest. If after this drive the oil on the dip stick is not already sludged up from picking up residue in the engine, and if the oil pressure running is at least 50-60lb. and at idle there is still some oil pressure that moves the gage I would consider it a decent engine and if there was no other limiting find while driving, I might buy it.
Note: There is an aftermarket suspension kit by OME (Old Man Emu) that will make the suspension feel better than new and the effect seems to never wear out, the OME set is around $60 * 4 shocks + $60 * 2 rear progressive coil springs, a real deal for what you get.

I had already made that oil change arrangement. Probably do it tomorrow. do the isuzus run low oil press at idle. Friend had a honda passport doing same thing.
#11536 of 11966 '93 diagnostic codes ?
Jun 07, 2007 (6:53 pm)
I'm George & have just joined the group - it seems to be right up my alley - got a 93 Trooper with 241k & it's started running rough when it warms up & works - got a 92 shop manual which seems 95% the same but the diagnostic procedure isn't - connector plug is different - even took it to a mechanic (which I seldom do ) and it seems it does not facilitate the Snap On scanner - there are so many sensors that could cause the rough performance I can;t afford the remove & replace till it works method - anybody know exactly how to access the diagnostic codes for my 93 3.2 DOHC ?

ALDL / DLC Connector is located on drivers side tunnel behind carpet.
Pic is posted here:
To access trouble codes, a jumper lead must be fitted to ALDL connector. With the ignition "OFF" connect these two leads together. Turn ignition "ON" but do not start engine. "Check Engine" light will begin to flash code 12. Code 12 consists of one flash, a short pause, then two flashes. After a longer pause, code 12 will repeat two more times. This check indicates that the on-board diagnostic system is functioning. If no other codes are present, the cycle will repeat until the ignition is switched "OFF."
If trouble codes are stored in memory, the lowest number code will flash three times followed by the next higher code number until all stored codes have been displayed. The codes will then repeat in the same order until the test lead is disconnected.
