2009 chevy tahoe fuel pump wont shut off

The fuel pump control module is controlled by the ECM - engine control module , Possibility of DTC'S stored ! You need to take to Chevy Dealer !
The engine control module (ECM) supplies voltage to the fuel pump control module (FPCM) when the ECM detects that the ignition is ON. The voltage from the ECM to the FPCM remains active for 2 seconds, unless the engine is in Crank or Run. While this voltage is being received, the FPCM closes the ground switch of the fuel pump and also supplies a varying voltage to the fuel tank pump module in order to maintain the desired fuel rail pressure.

Its a 1999 chevy tahoe. Changed fuel pump twice.

Could be the pressure regulator on the fuel rail. Pull the vacuum line off the regulator and check it for fuel contamination. There should not be gas in the line. If there is fuel in that line the regulator is bad and needs replaced.

Car want start after changing fuelpump

to change the pump , the fuel was drained out
so do you put it back and then prime the pump?
test for fuel pressure.
if non, then check for 12vdc at pump wires cranking
no 12v, you blew a fuse
if 12v good, the pump is bad or cant pump air, needs to be primed.

we check fuel pressure after every pump change;.
after all , that is and was the whole point of a new pump. right.
so check it.
over 30psi, (see FSM for full spec)

Ecm 1 fuse blow when attemping to start vehicle 1999 chevorlet tahoe replaced fuel pump

So as I understand it the fuse only blew after a fuel pump job.

There is a TSB on repeated fuel pump failures with these trucks. The fix is to also replace the harness connector that plugs into the tank harness.

Unplg the harness and inspect it before you turn the key again if you suspect this.

1996 chevy tahoe fuel system

check for voltage at the pump. If it has 12v there, (and a good ground) then pump is bad. there may be a pump fuse on the fuse block (can't remember) but if you find it has blown, the pump may be getting ready to fail. If fuse fixes the problem, replace it and carry an extra with you, then change the pump.
