How do I fix and 97 GMC 1/2 ton with a 350 vortec. Runs great once running. Sat for 5 years. If sits more than 5 minutes wont start without shot of starer fluid

have you changed the fuel filter and emptied the gas tank and put fresh gas in? Stale gas will not start as well as fresh gas and there could be water from condensation in the tank.

97 GMC yukon 5.7 vortex cranks but wont start i used to hear the fuel pump when i turn the key on but now i dont cked all the fuses and relay, OK help!!!!

You should try removeing the fuel filter its under the drivers door mounted to the frame then crank the engine to see if you are ectaly getting fuel flow to the rear of the filter from the pump if you are then replace the filter but honstly the most likely cause is the pump is no good these pumps last about 10 years there were problems with themand the new ones have many upgrades that correct these problems .If you can fix it with the filter you will still have to think about replaceing the pump in the near future if its the orgenial one if you want to keep the vehicle running

2002 gmc sierra 5.3 4x2 . problem is starts up and dies. changed fuel filter it started and ran about 1 minute died and wont run. got new fuel pump and dropped tank. sending unit pair has 5 volts the...

You should not see any voltage after the 2-second prime until you actually start cranking the engine. If you don't see power on the grey wire when cranking, try jumpering across the fuel pump relay terminals

yep,that sounds like the fuel pump is getting hung up on the bearings.don't forget to put a new fuel filter on too!
you'll see the blackness of the fuel that got stuck in the filter.

97 jimmy wont start

If it starts with starting fluid, this means the firing and electrical is fine,however, its not getting fuel. I suggest trying the fuel filter first,but, its probably going to be the fuel pump.
