Not all replacement fuel pumps work right out of the box. I had the heartbreak of replacing two of them before getting one to provide the right starting pressure (50 to 60 psi).
Connect a fuel pressure guage to the fuel port located at the rear of the engine to the right of the distributor cap. Be careful not to lose the cap when you take it off the fuel port.
The pressure has to be checked when the engine is cranking..Make sure the relays for the oil pressure and the fuel pump are working correctly - they are located in the rear of your glovebox. Both are necessary to allow your engine to start.

You have to put a guage on it to find out the pressure it may kick on but not enough pressure

REPLACE FUEL FILTER,CHECK FUEL PRESSURE, SHOULD BE SHOULD BE 9 - 13 PSI TBI FUEL INJECTION AND 55 - 61 PSI MFI FUEL INJECTION.WHEN YOU TURN ON IGNITION WITH ENGINE OFF.LET FUEL PRESSURE BUILD UP AT FUEL PRESSURE GAUGE TO CORRECT PRESSURE THEN TURN OFF IGNITION SWITCH. IF FUEL PRESSURE DROPS VERY FAST OR LEAK DOWN IN 10 MINUTES.YOUR FUEL PUMP CHECK VALVE FAULTY IS BAD.FUEL PUMP NEED REPLACING.BE SURE FUEL INJECTORS ARE CLEAN THEY WILL LEAK DOWN FLOOD ENGINE FOUL OUT SPARK PLUGS.

leaky injector/s is flooding motor, mechanically clean or replace. And clean throttle body while you are at it with spray cleaner. Should be almost spotless where large throttle valve opens and closes.

95 S10 blazer 4.3 vortec skipping code po172 and po300 possible solutions


P0172 system too rich bank 1. P0300 random multiple misfire. All are a common symptom of either bad fuel pressure regulator or leaking injector. Need to pull off intake plenum (upper) You should visibly see a clean side or part of intake manifold (lack of carbon buildup) Reconnect fuel lines. Energize fuel pump (turn on key to run) Most likely you will see fuel dripping out of rear (fuel pressure regulator) or nylon lines to each cylinder (fuel injectors). Once you see which is leaking will need to replace. Once they are repaired will need to clean or replace spark plugs & change oil & filter.

Could be a fuel issue, Start by changing the fuel filter, if that doesnt work you might want to drop the gas tank and check the strainer on the fuel pump and make sure the tank is clean.

Not cranking


If the engine is locked up try pulling spark plugs to see if radiator fluid is inside. If so the intake plenum would need replacing as well as an oil change.

1999 chevy blazer wont start


THE FUEL PUMP IS BAD.

if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.

and i doubt that you are seeing enough fuel pressure to run a vortec engine.

low fuel pressure equals a non running vortec
