#178 of 381 02 Tahoe starting problems
Nov 15, 2009 (3:25 pm)
My 2002 Chevy Tahoe is having intermittent problems with starting. Engine cranks but won't start. Takes multiple attempts to start and when it does fire it does stay running unless I start to lightly feather in gas by depressing the gas pedal (I know this is not recommended.) The engine will run poorly and then idle down below 500 RPM's amost to the point of stalling. In the last 6 months I have replaced fuel filter, air filter, fuel pump, battery. there are no DTC's in the computer. it is a 4.8L V-8.
What is really odd is that the problem has occured on two different situations:
1.) Most recently on a return from an extended vacation (>5 days) the car would not start or stay running at idle
2.) a quick stop at a store for 5 minutes, return to vehicle and it will not start or stay running.
The fuel rail losing pressure sounds likely but the fuel pressure regulator does NOT have gas in the vacuum line and each situation above seems like they are mutually exclusive.

did you ever find out the problem?

Did you every get a response on what the problem may be? We are having similar problems with our Tahoe same year. Curious as to what the outcome was.

Please view this picture to help answer my questions.
Thanks for any help you can give.

My Suburban's starter is not turning fast enough to start the truck. In fact it acts like the batteries are both drained. The batteries have both been charged, and I hooked up jumper cables to boost the power when trying to start, but it didn't change the symptoms.
My inspection of the cables showed no corrosion at the terminals. My inspection of the starter innards shows grooving in the brushes and copper (aren't they supposed to be smooth?), and from what I understand from past starters, there are supposed to be slots between the copper contacts (at least I think that's what I've seen before), but there isn't on this one. I've never before seen a worn out starter in terms of the copper contacts, so I am wondering if you think this starter looks perfectly functional or if it has run its lifespan. Take a look at the picture, and if you have any questions, leave an answer or email me at "adam berkey . biz" (no spaces)
I took it down to Schucks to get tested, but their test doesn't include the friction of the compression of an engine, so I'm wondering though it passed the test on their testing equipment, that the actual use of it trying to compress the cylinders in the truck need more "juice."
#183 of 381 02 Tahoe no start
Dec 19, 2009 (8:46 am)
I have a 02 Z71Tahoe that will not start. Problem started about a month ago when I went to start the truck, turned the key, no noise! Lights, radio, dash lights all came on, but no action. Came back a hour or so later, it started right up! Truck would not start a few weeks ago, got it towed to my house, soon as the truck was lowered from tow truck, I got in just to check, and it started right up. Drove fine with no problems for a week, then all of a sudden, problem came back again.tried jump starting, but no results. How do I know if its the starter, battery or ECM? Please help!!!

Left the Tahoe with the dealer for 3 days and they had no solution. However, it has not failed to start since. over four weeks ago now. Love you know if you figure your problem out. Then I can check mine.
#185 of 381 92 Burb not running idle orstarting on own
Dec 19, 2009 (4:56 pm)
ok this problem has been eluding me for months now. My 92 Burb will not start without adding starting fluid and then will not idle at less than 1500-2000 RPM. I am getting 12+volts to the injectors I have changed the oil pressure sensor, fuel pump, fuel filter, ESC, EEC(computer) O2 sensor, map sensor, Idle air control valve, full tune up and full oil change. The symptoms are; Vehicle will not start without starting fluid, then once started will not idle below 1500-2000, it appears to shut off the injectors. I have talked to several techs that I know and they are all baffled. ANYONE HAVE ANY OTHER SUGGESTIONS.

Have you checked the compression in each cylinder, and how about a leaking intake manifold?

No leaks that I found and I rebuilt heads and reinstalled them so compression is wihtin 2lbs of each other. however if I put fuel in the TBI it will start then if I keep it at above 1500 RPM it runs perfect it is once I try to let it idle the injectors shut off
