Fuel pressure regulator may not be working properly, allowing fuel pressure to bleed off overnight. Try (before going to crank position on key) turning the key on for 3 - 5 seconds, then back off. Do this three or four times. (The fuel pump will run for 3 - 5 seconds before the ECM turns it off if you don't go to the start position.) This should allow pressure to build to what is needed initially to start the engine. Now try to start normally. If this works, you need a new pressure regulator. It is located either in the fuel rail, or on the fuel pump itself.
The symptoms sound very similar to when the antitheft system locks out the starter. "Runs for 5 seconds or less, then stalls". "Starter not working, but still turns over when jumped at the stater" Maybe read thru this link and see if this sounds like what you are experiencing. http://vatspasslockpasskeysecurityhelp.yolasite.com/
Not sure about this, but you might want to find your fuel "reset" button for the fuel pump. It's usually located in the trunk.
You say that it's getting fuel to AND from the filter (?); there might not be enough pressure to get to the injectors.
Try turning the key on for a about 5 seconds, but don't try to start it. This actuates the fuel pump.. Do no pump the gas pedal. Turn the key off, then try to start it.
If it doesnt start, turn the key on but don't try to start it. Pump the gas pedal 2-3 times, then try to start. You usually should not pump the pedal, but in this case it might just need a little "kicker" to get gas through the line.
If it doesn't start repeat this procedure. Hopefully it starts.
Note: Never crank a car over for more than 4-5 seconds. It's hard on the starter and will wear your battery down really fast.
Here is a great write-up on the subject. This will get rid of the entire VATS system. It was the only thing that saved my 94 Park Avenue: http://newrockies.com/vatsbypass
did u replace key & lock cylinder or ignition switch,,??if u have no power at ignition switch(ck with test light) look for broken wire off starter ? ck power at fuses,,ect,,
sounds like it needs an ignition switch. the reason it dies after a few seconds after jumping the starter is bc the security system from gm thinks you're stealing the car so it kills the fire. the security system goes thru the key so if the switch is bad, it wont run no matter how you try to crank it
if starter will engage and engine can turn over quickly it should start.
however.. i dont know how you are verifying it has fuel as its a high-pressure FI system.
these systems by GM are VERY finicky and unless within spec precisely it will NOT run. i suspect fuel pump is putting out less than 57# which is min for these.
fuel pump known failure part. if replaced you MUST also replace wire harness at tank as they usually fail internally w/melted wires you cant see through wire sheath. low voltage will KILL the new pump.
is this a supper cahrged grand prix if so check fuel pump resistor located behind right front head light or on fire wall its made of white ceramic has to wires going to it jump the two wire on the connection going to it if it runs longer then 15 min then replace resiustor.
