SOURCE: HELP! HELP! SOMEONE PLEASE ! 2001 chevy blazer fuel problems

I would check to be on the safe side the fuel filter is going in the right direction. The arrow is pointing towards the engine away from the fuel tank, Then you need to make sure the fuel pump wiring connections are good contact and did not come loose when driving.

SOURCE: engine wont start without priming with gas first, then runs well

i have the same problem on a 98 jimmy 4.3 4x4.
i replaced the fule pump and have good pressure.
new wiers & coil (good spark) no MIL & no codes.
will only start when primed. it will run & drive all day
with no problems.
but once it has been turned off (warm or cold) i will
have to prime it once again to start it.
i have another engine that was in it before it spun a bearing.
it ran fine so i know all parts are good.
i swaped the mass air flow and throttle body but i still have
to prime it everytime to start it. am i forgetting something?
should i swap out the intake with the injectors?
any help would be sweet. thanks.

1999 blazer only starts when primed and then wont start after sitting


Black smoke is usually extra fuel, but you say you are priming it to start so that could be why.
Have you checked fuel pump pressure before and after cranking ?

I Let my chevy Blazer run out of gas,nw it wont start even though the relay and fuelpump is working.


Is it electric or mechanical pump? Electric is with fuel injection. If its fuel injection, you should hear the pump run when you turn ignition switch. If u don't hear it, try starting, if no, turn off then on. It will self prime. Carburetor is with mechanical pump. I usually put few drops of gas in the carb. Start it, if no, more in carb till it stays running.

97 chevy blazer w/ 4.3 won't start unless i pour full directly into it....what is causing this. was driving and it just stalled ...fires but won't turn over completely


if you can put fuel in throttle body and it runs. then it is not getting any fuel. check your fuel pump fuse and the relay, if ok, then you may have a bad fuel pump or a plugged up fuel filter. check filter and fuses first. good-day !!

My 1997 blazer won't start unless primed in the throttle body it runs fine after when shut off for a day it needs primed again


This sounds like a fuel pump is starting to fail. The system is designed to keep, or at least prime rather quickly to allow for efficient starting. If the pump is begining to fail or, has a plugged fuel filter (which will kill a fuel pump), it may create this issue. One other item to check is the coolant temperature sensor. If it is reading warm when it is cold, this symptom will occur.

I have a 1997 Chevy Blazer that has oil, but no pressure


There's something you can do to check if the oil pump is still working screw off the oil filter and start it only for a few seconds if oil shoots out the pump is working if it doesn't the pump could be clogged or it lose prime if it's working check the wire going to the oil pressure switch may be broken.

97 Blazer low fuel pressure and stalls in gear


If you have the spider fuel system, fuel pressure, key on engine off, 60--66 psi. After it starts it will run with less pressure. Are you using quality brand new fuel pumps?
This fuel system is noted for problems, including the fuel poppets.

2001 chevy blazer not starting


I had this same problem with my 1997 Blazer, which required a fuel pump replacement as Nitrobike said. The sign to look for is when you get in the Blazer, turn your key forward to the accessory position, but not the start position. You should hear the fuel pump charging. It sounds like a hissing or whirring noise for about 2-3 seconds while it pumps fuel into the lines to prime the engine.

Fuel pump replacement isn't cheap, about $700-$1000.
