#261 of 311 GMC Jimmy - Hard cold start
Sep 07, 2011 (5:51 pm)
Hi. I have a 2000 Jimmy. When the outside temp is below about 40 degrees, i have issues getting it to start. I believe the issue is related to ignition switch /module or lock cylinder since i do the following to get it to start. - Either wait until the day warms up the truck some or use a hair dryer to warm up the lock column area.. When starting, you need to barely turn from run to start to get truck to start up in cold weather.. any time above 40 degrees or after it starts up no matter the temp, there are never any issues for the rest of the day.
Anyone come across this before?
#262 of 311 Jimmy 96 (Gulf Model) stalls while driving
Sep 22, 2011 (9:58 am)
I live in Riyadh, Saudi and bought a Jimmy 96 4.3l/4x4/v6 during 2001. It was running smooth until two months ago and started stalling on highways. Had to wait for 10-15 miniutes before it start again. Will run for another 10-15 miles and stops on its own. My mechanic identified the problem with fuel pump and was looking for a new one. Not available anywhere in Riyadh including the GM dealer (was quoting over $1000 to order from USA). My mechanic tried with three other fuel pump including a geniue one of Ford, but was running for a day or two and then started giving the same problem. Tried to get a old part from stranted cards (there is an area near Riyadh called AlHair, where in they sell parts of old cars), but could not find the geninue part. Ater strugging for over a month (and spend over $800), I found a Delphi store in Riyadh which was selling the original fuel pump. Bought one for $75 whcih fixed the issue and running fine for a month now.
Thought of sharing this experience which may help someone in Saudi with a similar issue.

Had the similar problem with Jimmy 96 and changed the fuel pump (not the OEM) and did not resolve the issue. Finally replaced fuel pump with Delphi (OEM) part and is now running smoothly as before.
All the best

many engines have an over heat cut off, if this is malfunctioning or getting a faulty signal (that says the the engine is hotter than it is) this would explain why it cuts off at a regular 180* and won't recrank until it cools off. also, could be a faulty temp reading (indicating lower than actual temp) and the cut out is working as it should.
Try running without a thermostat, engine should not get to operating temp; it the engine still dies its not the over heat cut off.
