Afternoon Gents,

I have a 2003 Grand am G.T 3.4 79,900 miles.
Was trying to leave work wouldn't start.. waited a few,came back stil wouldnt start....No lights were/ are trigered on the dash. Reset the vats 4 times by waiting 10 mins. No lights would flash or anything..Still wouldn't start.Turn my key on I dont here the pump priming... went bought starting fluid,it will start and run with starting fluid..while running still no lights / codes. towed it home switched relays under the hood still nothing.Thought it was the fuel pump went purchased a Delphi $300 put it in. Still wont start and cant hear pump priming while cycling the key. Switched relays again put on a machine all passed.Wemt to fuel rail pushed in valve and gas comes out. I am stuck.

New Delphi pump
Switched relays under hood
Checked all fuses
No codes stored
Gas comes out of pressure regulater valve ????

I am stuck. Any Ideas gentlemen

did you rule out any battery issues? (head unit, amp, subs can draw power like crazy sometimes, and may need to check wires)

my car wouldnt start either. would with starting fluid but stalled right out if i didnt up the rpms. replaced the map and it started on its own and ran. got a rough idle still but it runs.

Thanks guys, fingered it out, Unbeleivable.. underneath the car by the back passenger wheel,theres a 2 plug block.. we started to chase wires and found one that was corroded and broke,fixed the wire and now I have a power to the fuel pump!

New Fuel pump fuel filter. When we installed it,it read the right amount of gas..Went today and filled her up @ 3.79 a gallon..Get in the car and reset my trip.Look down at my gas gauge and it only regeisters a halg tank ???? Anyone had this happen?

Personally i would double check the fuel level sender

Update: My gas gauge just sits at half tank. Guess I am going to have to drop the tank??
