#926 of 939 1996 Tahoe Starting and Running Problems (Crankshaft Position Sensor) by jcb4green Aug 27, 2009 (2:29 pm)
My 1996 Tahoe was having terrible problems starting and running correctly. The initial diagnosis was the crankshaft position switch was malfunctioning. After almost $2000 dollars of replacing the sensor, engine tune-up, fuel filter and fuel pump I was still having the same problems, but not all the time. I had a local mechanic due the work and he said take it to Chevy and have them diagnose the problem, which they determined was still the crankshaft position switch was malfunctioning. Since my mechanic had done the original work I took the Tahoe back to him with the Chevy diagnosis problem. He crawled under the truck with it running and saw the sensor moving around while it was running. He took the sensor out and discovered that one of the mounting bolts screws into a brass fitting inside the plastic timing chain cover. The brass fitting was loose and just needed a screw driver inserted into it to spread it to increase the tension on the plastic cover. My mechanic put it back together and it resolved all my problems, meaning most of the $2000 dollars I had spent trying to fix a problem that ended up being caused by maybe a 25 cent brass fitting in a plastic cover. Live and Learn. By the way my 1996 Tahoe has almost 154000 miles on it with the original engine and transmission.

Replying to: jbl2001 (Sep 05, 2009 8:26 pm) I reread your problem symptom, and may have mis-interpreted what you were saying. Explain the 3K rpms statement. Are you saying that you are in park and starting it and rev it to 3K and it stumbles (no load condition).....or does it run okay at low rpm and low load?   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.

#934 of 939 fuel pressure regulator by tkdfan Sep 14, 2009 (1:13 pm)
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.
