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.

Check your connections. did you run the fuel pump wiring under the drivers side door sash like GM did?.. if so check for nicks in the wire or bending or cracks.. this happens.. happened to me. check your fuel pressure. 40 dollar part at an auto store. If its below 59 PSI it wont work. And blazers are very intolerable to low fuel pressure. Also try taking the negative post off your battery for a little while and then putting it back on and if you can get it started again drive around (if its safe and running decent) for at least 30 minutes to get your car computer system acclimated to a new functioning part. Did you check the fuel filter?. rule of thumb when a pump goes change the filter its always the last thing people expect because we all jump to catastrophic engine failure at the first no start moment. lol.
Make sure that all your ducks are in get my drift.. Air oxygen fuel thats the mixture you need to check all those vital parts. before pulling your head off.

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.

Well if theres power going to the relay but not out, then you need a new relay. If theres power in and out of the relay, you might need a new fuel pump. The electric fuel pumps inside the tank are actually lubricated by the fuel as it pumps it, and if it runs dry long enough, it can burn out the pump

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 have replaced the fuel pump amongst a lot of other things. I can spray gas or starting fluid in the throtal body and it will run rough untill the fumes ware out. Its a 1995 ford explorer 4x4 xlt


If you hear the fuelpump operate the first 1 or 2 seconds when the key is turned to RUN position, the fuelpump is working. If you do not hear the fuelpump run, check the Inertia switch which should be in the side panel of the rear cargo area. If you have an owners manual check for the Inertia switch location.

To reset the Inertia switch, hold the button on it for 2-3 seconds. You should now hear the pump run. You may also have a fuelpump relay under the hood in one of the Powerboxes. The Powerbox may have a fusible link from the Battery. When the fusible link is OK and the Pump Relay is OK, there is a fuse in the Fuse panel. Then finally the Ignition switch will trip the Pump relay. As power flows through the wire to the fuelpump the Inertia switch can break the power connection.

So you have 5 powerpoints before the fuelpump will work. Fusible link, Pump Relay, Fuse Panel, Ignition Switch,and Inertia switch. These must all work before the fuelpump can run.

Fuel pump not pumping


your fuel filter is probably plugged up which is what probably caused the pump to go initially. after the fuel is out of the lines the first start will take a while.

Where is fuel relay


The fuel pump relay is only for the fuel pump priming when you turn on the key. After the vehicle starts the oil pressure switch takes over and runs the pump. If the pump is shutting off after the motor is running the oil pressure swith is probably bad. Let me know if i can help you further.
