#93 of 607 Suburban shuts down while driving.
Sep 29, 2006 (11:41 am)
I have a 2002 Chevy Suburban, 5300 engine, half ton, 45,000 miles, automatic transmission. Recently the vehicle shuts off completely when driving. No "check engine" light comes on, so there are no codes available to read. It will shut off at different speeds. I leave it in gear and coast to a stop. I let it sit for a moment, a minute or two. I start the engine, revs up okay no problem and go on down the road running okay. Shuts down again and I repeat the same process again. I have taken it to the chevy dealer. They checked all electronics and fuel system. They tell me they cannot find anything wrong. Fuel pressure checks okay. All electronics check okay. The garage thought it might have been a bad load of fuel. Have gone through many tank fulls since then. Will quit doing it for a few days, then begins to act up again. Any one have any ideas. Some have told me that it could be the fuel pump acting up when it gets warm. Then when I stop for a few minutes it catches up with demand. Does that make any sense?

When reading your post the fuel pump acting up came to my mind as a possible reason before I even got to the end of your message. Any other kind of problem should set a code but I do know another thing that in my '04 Tahoe shut down the engine without setting the code.
I had a bad connection on the MAP sensor wire harness and when I had the problem it shut down the engine when I touched it but no code was present. Big surprise not to have code for this. Repeated it for about half dozen times and no code was set.

I am having the same problem that started six months ago. I tracked it to a TSB on stalling and it said replace the fuel level sensors. I did this at a cost of 757.00. It did not help. I then took it to a different dealer and they could find nothing wrong;however the service guy said it could be a defective crank sensor that could shut down the spark. There were no codes that showed up on this but he said we could replace it a hope it cures the problem, at a cost 325.00. Since it was at the shop already I told him to go ahead and replace it. That was three days ago and so far the problem went away. I hope this will help you. Keep me updated on your vehicle. I too have had some problems with my 3/4 ton suburban 8.1 engine. Good Luck Kim M.

Wow, $325 to replace Crank Shaft Position sensor!
I replaced mine. The sensor cost I think about $65 + tax.
For changing the sensor the starter motor must be taken down, two bolts. Sensor has one bolt. Need torque wrench for starter motor bolt tightening.
If you buy plastic ramps and torque wrench and part I bet the cost will still be well less that $200 doing it yourself.
I had the tools already so no cost buying those but $325 is just ridiculous when the job itself takes about 20 minutes at the shop. For me it took about 30 minutes when I need to set the ramps and then crawl under the vehicle.
Being hands-on person really pays back quickly with these cars.

I have a 1998 suburban 4x4 with an alternator prob. My family and I are currently broken down (fortunately we made it to a motel) after the battery light came on and the lights dimmed then the car died. My husband loosened 3 bolts and it will not come loose. there is another bolt on the back left side but it appears to be attached to the frame holding the alternator. What are we doing wrong? It is almost sunday and no chance of finding a mechanic until Monday. Help!!!
OH, I am also having problems when accelerating up a grade and the engine starts shaking. Replaced the coil, spark pluhgs and wires and now , the number 3 injector. Any ideas?

This is to didierf. What did you find out on your shutdown problem with your suburban? Thanks Kim M.

Have not had a chance to follow up on some of the suggestions. I do plan to take it to a garage and have them check codes on the PCM(powertrain control module). That was one of the suggestions that I check to see if that produces any codes related to the problem.

Thanks for your reply. Keep me posted. I'll see if I get another failure after I replaced the Crank sensor. I've had no shut downs yet since I relaced it, but it was just a guess. Thanks Kim M.

got an '88 suburban silverado over here thats havin some interesting window problems. they seem to be sticky, but i sprayed silicone in the cloth tracks and it made not a bit of difference. when rolling up the drivers side window, the motor just stops and doesnt work for a few (20-30 seconds) and then starts going again. is the window motor givng up because its so sticky? or are they even sticky at all because if they were, then the silicone would have fixed it right? im so confused because its gonna be mine here real soon when i get my permit, and i dont want to have the motors replaced, so if it is the motors then ill bribe my mom to replace them before its mine. anyone here have any ideas on how to fix it?
