SOURCE: Chevy Blazer won't start; fuel pump needs replacing

Before spending several hundres on a fuel pump, I recommend doing a fuel pressure test. You can get a test gauge pretty cheap at a parts store. If the pump is junk, you raise the truck, lower the fuel tank, unplug the electronics from the pump at the top of the tank, then with a hammer and flat head scrwedrive, gently tap the lock ring in a counter clockwise direction until it pops off. Pull the pump assembly out and install the new one. Reverse directions to install.

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.

1994 chevy 3500 6.9 diesel you drive it acs like running out of fuel half to bleed lines to get air out to start back up


sounds like u got a clogged fuel filter, or you have got a fuel line somewhere that is sucking air in, could be anywhere from the pump back to the tank, if that shows no luck, get a piece of clear hose and put that just before the pump and look for bubbles, the slightest of bubbles will cause it do run rough and stall
failing this and there is no air bubbles i would say your injector pump needs rebuilding but this is rather unlikely unless u have got a fair few miles on it


hope this helps

98 chevy 2500 wont start after cutting off while i was driving


Turn the key to the on (not run) position and listen tosee if you could hear the fuel pump turn on (prime) for a few seconds. If not, check the fuel pump fuse and if its good, its probably a bad fuel pump.

How did it die? Did it feel like you were out of gas?

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.

My 1996 Chevy Tahoe wont start unless you put gas into the throttle body


Will it continue to run aftre you manually prime it? If so, you are lossing fuel pressure over time which may indicate a leak in a line and or a faulty fuel pump. (low pressure) Could also be a restriction in fuel line (filter) Frozen water in the line is not unheard of in cold climates.

I ran out of gas. When I put gas in the tank the car wont start. What do I do?


hopefully all you need to prime the system
just turn the key on for 5 sec...do not crank and then turn the key off 5-10 times

each time you do this listen for the fuel pump...you should hear a whining noise
if you do not hear the whining noise then you killed your fuel pump when you ran out of gas

do you drive often below 1/4 tank?

Where is my fuel pump at? on a 1995 chevy camero 3.4 yes ran the car out of gas put so in wont start now what should i do first


Your fuel pump is in the tank. Turn on the ignition, and listen if you can hear the pump run in the tank. It will only run a few seconds if the engine is not running. You can repeat this several times to prime the fuel injection.
