Question about 2000 Chevrolet Blazer

1 Answer

I own a 2000 chevy blazer with a 4.3 v6 vortec. It will turn over but not start up. I replaced the fuel pump, the fuel filter, the plugs and wires, and the pressure regulator. If i dump a little gas in the throttle body it starts and runs fine but wont start its self. any ideas? Im getting fed up.

Did you check power and ground at the fuel pump connector?there should be power at two wires at the connector,one should have constant power with the key on and thats for your fuel gage,the other power wire should have it only when cranking or for about 3-5 seconds when the key is turned on,check both of those first and that will let you know that everything is fine all the way forward of that connector,also did u replace just the pump or the whole sending unit?if you just replaced the pump the connector that runs fron the sending unit to the actual pump itself inside the tank also goes bad on this setup too,look for brown or burn marks on the inside of the sending unit where this connector hooks uo,hope this helps

what did you do (replace it) if you still have a miss you may need to tune it up / make sure the fuel pump you bought is for the right psi for your blazer

'94 S 10 Blazer V6 Vortec EFI. Fuel pressure good, new fuel injectors installed, fuel pump works ok. Only starts with starter fluid sprayed into air intake. Any Suggestions?


your statement is fuel pump work ok, have you tested for proper fuel pressure. just because the fuel pump works it could have less pressure needed to start the engine. maybe the fuel filter is plugged. start out by replacing the fuel filter, if this doesn't fix it, you need to pressure test the pump. even 10 psi reduction in pressure will allow the engine not to start.
