motor problems

I agree with the ecm/ecu problem with the b2600i. I had a 2600 that couldnt start and found by searching on the web that the ecm in these trucks go bad. I got a used one from the wrecking yard and it started right up.

Check out this link. Not sure if the ecm in your truck is bad but maybe it could help you find your problem.

i can't find anyone done here that can do a scan on a 1991...they tell me they can do only 1996 and up...

You cant do a scan on it, to see if teh computer is bad you need to remove it from under the passenger kick panel and take the cover off and look. Id try to test the fuel pump first though like mazdatweaker suggested.

i thought it was under the driver's seat??? ima get the fuel pump tested thanks!!!

The box under the seat is the ABS controller the computer is under the passenger kick panel.

ite thanks...no wonder i didnt have any change lol.....my parts truck is auto and my truck is a standard are the computers the same???

know of where the height switch for the ABS be located? Its not a BIG deal to me but since I lowered my ABS light is on...just a annoyance more than anything
