Question about 2002 GMC Sierra

1 Answer

02 GMC Sierra Diesel

Truck won't start. It will turn over and over but won't start. The lights come on. It makes a hissing noise, which I don't know if that is a problem or not. I know glow plugs can be a problem but even when it warms up later in the day it still won't start.

Ran out of diesel now vehicle won't start


This is not unusual on a diesel. What happens is there is air in the system. If this vehicle has an electric fuel pump loosen line where fuel enters injection pump then turn ignition key to the on position and watch for fuel to appear and then quickly tighten line before turning off key. Then try to start. If does not have electric fuel pump will need a second person. One will loosen line and watch while other cranks vehicle until you get fuel and tighten line before the other person releases ignition switch unless vehicle starts first. If that doesn't do the job do this where line hooks onto each injector. Probably will not have to do this to all injectors but could run rough until all the air gets out of everything. I have farmed with diesel tractor for 25 years and dad I drove the gm vehicles with the 5.7. You normally don't start a diesel without bleeding the air out of the lines although some will self bleed most won't. Hope this does the trick.

1989 gmc sierra 6.2 liter diesel hard start when hot


hi, i have seen this problem ten years ago twice, but i was dumbfounded by the answer. all details aside, I replaced the ecm, and never had the problem again with both of them. this repair was a recommended repair by the local truck depot in my town, they stated the ecm got hot along with the truck and it lost the injector sensor signal. now, don't take this solution and run with it, i haven't repaired a 6.2 diesel in ten years and i maybe off track completely. but at least maybe you could ask around your town or maybe a large truck facility about this. of course, you should take to a shop to have diagnosed. hope i could help.

Occasional hissing noise from a/c 2000 gmc sierra


This is pretty normal, the way the system works is by forcing liquid freeon through a orifice, the liquid turns to gas and gets very cold, the hissing is that process. You might be a tad low on freeon, but you shouldnt be worried.
