Replying to: jbl2001 (Sep 05, 2009 8:26 pm) Or is the situation that you are really trying to accelerate fast (at say 30-40 mph and the car isn't able to accelerate (high load situation). If it is the later, you could have a bad fuel pump, very common.

| my mechanic has diagnosed my very-hard-to-start 1999 gmc suburban problem as bad fuel pressure regulator. He has quoted 7 hours and $1100 for the job (r&r upper intake, associated gaskets, nipples, oil change, etc). Labor rates can vary, but is the amount of hours about right? i've seen posts that this job should take much much less, but I think those engines have the FPR mounted outside the engine. Been doing business with these guys for 5+ years and never did me wrong, but appreciate your impressions on this. | |
2002 Suburban Dome lights/ door lights not working. I have checked the fuse and replaced the headlight switch and the lights still do not work. I took one of the dome lights down and put 12 volts on it and all the lights worked. I suspect there is a bad relay somewhere but I can not find it. Thanks, Bob

Replying to: rgerber (Sep 22, 2009 6:58 am) But interior lighting in later model Suburbans is controlled by the BCM (Body Control Module), which is basically a computer that manages when lights are turned on and off.....based upon input signals from light switches, timers, door opener, security system, open door switches, etc. Don't think there is anything else I can offer... |
