1st check all the fuses in the vehicle. Next, check your power to the pump and the ground wire from the pump. I have discovered a lot of issues with the ground wire not making contact. A lot of people state that they checked and have power. You also need a path to ground. Also, check the fuel pump relay. You can take another relay, like from the air conditioning, and plug it into the fuel pump relay spot. This will tell you if the relay is junk.

Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

SOURCE: 90 chevy k1500 350 tbi fuel problem starts but wont stay running

try bypassing the oil pressure switch on the back of the block behind the distributor, if there oil pressure switch goes bad it will do this. had one that drove me nuts trying to fix it then figured out I had to buy a book and low and behold thee it was 3 wire oil pressure switch you can't see between the engine and fire wall just behind the distributor and costs 8 bucks to buy new.

I have one question first how did you measure the fuel pressure at 45 psi it should be 66 psi .
I would take a good look at the in line fuel filter before I replaced anymore parts .
It should be on the frame rail some ware under the drivers door look for the lines from the pump

2002 chevy express fuel pump/crank sensor?? not starting


i had a similar problem and called the dealer during lunch hour. i talked to a mechanic, the distributor in these vehicles is plastic, and is prone to cracking.not just the cap but the body also, I have been taking the cap off and wiping the moisture out of the cap. or replacing the cap but the problem is I need a new distributor. just a cheep way to get rolling is cleaning the inside of the cap, especially when it is very damp or the outside temp changes alot during the day. good luck.

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
