Unfortunately the fuel pump can still be bad. The pump has a check valve on it that wears out. The pump will continue to run but, struggles to supply enough fuel to start the engine. You can buy a fuel pressure test gauge from Auto Zone or that type of auto parts store and check the pressure. You can purchase a fuel pump from them too.

2000 chevy surburban 1500 will crank but no start. waited one day then started. Ran for a week. Stopped again. Waited one day no start. Waited three days started again. Any suggestions??


more than likely your fuel pump went out. it's in the tank. you can try spraying carb cleaner in your throttle body and have someone crank it. spray small amount of carb cleaner beware of backfire. do not acclerate while cranking. if vehicle turns on its your fuel pump

Car stalled while running


Check under the back seat for an access panel to the pump. Might be the pump or just the level unit. Good luck.

99 suburban wont start sometimes


I had a similar ongoing problem with my 1999 GMC Suburban C1500, it occurred only in the hottest days of the Texas summer. In addition to not starting, the truck sometimes exhibited symptoms of misfiring while driving at highway speeds, as if the engine seized or as if there no fuel being delivered to fire.
I found a small garage mechanic who swore he could fix it after years of taking it to the dealer and other franchise repair shops and getting the same answer "we can't find anything it like you described, it won't do it while we're testing it, bring it in right away so we can get the history codes....blah, blah, blah". I always thought it was due to an intermittent electrical grounding issue. Anyway, long story short, the small garage mechanic was guessing a lot of the time, but after changing the fuel pump, the sending unit, fuel injection system and many return trips to the garage with me saying 'that wasn't it, it's still doing it" it finally turned out to be a faulty wiring connector link in the harness assembly ABOVE the FUEL TANK that came from the pump or sending unit. When it got hot the link would melt and create a short, when it cooled a bit it would still conduct. We replaced the wiring connector and 4 years worth of unexplainable intermittent starting problems disappeared. I spent $2K to $3K over the years, when it finally turned out to be a hidden $12 wiring connector.

Good Luck.
