2003 pontiac grand prix gtp supercharged wont start . i have no power on my fuel pump my relay is good bought it new fuse not blown please help me
Has car been bumped,are jarred?
not that i know of
i hear relay kick in when i put my ear to it . i checked voltage to my pump wires wth tester and no voltage . i have a new battery and a brand new fuel pump
There is and insertia swicth in your trunk that can cause losse of power to fuel pump,but this is usually caused by someone bumping your car.
i checked plugs for fire and i got fire
If you here the clck at relay you have fire there,have you checked it at the pump?
is that switch plug into the fuel pump wiring harness
Yes it will kill the fire to your fuel,it is there in case of wreck or someone bumping you,
It has a reset button on it,it is red
yes i wired it yesterday then took wiring apart and checked it that way and nothing
Checkthe inserctia switch,it,s in your trunk,behind carpet,near bottom at tell light,s,someone may have bumped it and you did not see it
Your,s may be on one side or the other of your trunk,
ok fuel pump harness runs to that switch. then anther harness plugs into that, then those wires run under my seat. is this that the switch
Yes possibly,it go,es to switch before pump
i dont see it . i see the where the other end of fuel pump harness plugs into , but no red reset button
theres one wire on that switch that runs under car thrugh the trunk
is it possible its not in my trunk
i diddnt see it
Ok,i done a little research,your car doe,s not have a inestia switch,it is biult only with a low oil sending unit cutoff,if car is low of oil it will not let pump cut on,or could be bad sending unit,the only other thing that will cause this is your anti theft system in your car.
