buddies truck

2000 130k manual trans 4x4

stalled on freeway today, but caugt by it self. stalled and no start 5 minutes later.

1st thought cam sensor.....

changed, no fix, threw a second one at it just for grins.

fuel bowl full.

no fuel smell at exaust when starting.

burn harness shorting out idm????

unplugged both vc connectors and no power while crankin.

no burned wire smell at oil fill,

havent taken vc's off (another reason i love my 97)

any more ideas?????????

gotta leave for work at 0400 so im not getting under the vc's tonight

 

Sounds to me like a PCM issue. Did you happen to check the fuses? Possible fuel bowl heater short? Does it have a chip?

Max

 

Yeah what Max said.

 

chip pulled, fuses checked good, no cel, no code scanner....

wondering about pedal issue.....throttle pedal

 

Throttle pedal I would think would not make it stall so much as just make it idle.
How about a failing IDM relay?

 

thats my thought for today was idm relay or idm. wheres the idm relay on that truck

 

I just bought a Helminc service cd-rom for my truck, but it's at work. I'm a very early riser so I won't be there for 3 hours. I'll look it up then and post it.

 

Hmmm, this manual is very poorly laid out. Not at all orginized like the Bentley CD's that I am used to using. It's going to be a while if I find it if I do at all. For now I have to get to work. Sorry I couldn't be more help right now. I'll try later on when I have more time.

 

The IDM relay is relay #2 in the power distribution box. It is the second relay up from the bottom on the right side. The IDM fuse is #8 which is the fifth one down from the top on the left side. The PCM is relay #1 (very bottom right) and fuse #22 (center top).

yeah know what you mean kwik i have the same problem with the cd for my 97 very hard to navigate

fuses are all good, gonna check out that realy today

 

The IDM (injection driver module) relay for a 2000 model is as shown in under hood box. Hope this may help.
