2004 pontiac grand prix non turbo 3.8 stalling

ok bb lets talk. - fuel pressure 160 - no codes or check engine light - refueling / putting gas in the tank seems to be restricted . starts and runs - shuts down after 5 or 10 mins but restarts - coil packs replaced because one had heat cracks and ecm replaced - crank sensor replaced earlier in the year. vehicle not at my location but interested in your opinion. - any ideas?


what would cause the

what would cause the restricted fueling issue all of a sudden? has 138000 miles on it. haven't removed the fuel fill tube yet but someone may have stuffed something in it at my granddaughter's college apartment.

Wild weasel, Hey

Wild weasel,

Hey brother,

Fuel pressure is 160 but where in the line is it 160? In other words before or after the fuel filter?

Is it 160 at the rail?

Has the fuel filter been replaced recently?

Have issues with the “Fuel Pressure Regulator” been ruled out?

Have “Fuel Pump Relay” issues been ruled out?

Have frozen fuel lines been ruled out?

Has damage to the fuel lines been ruled out? (bends or kinks for example)

Any:

Blown fuses?
Blown master fuses?
Blown fusible links?
Blown Circuit Breakers?

Are ALL the injectors firing? Check with a “Noid Light” if necessary.

Is “Exhaust System Backpressure” Excessive? Check with “Back Pressure Tester” (and or) “Engine Vacuum Pressure Tester”.

Have more for you weasel, but get back to me with answers to ALL the above.

BTW:

No gettin around it brother.
You gotta pull that filler tube.

Could be some ASS HOLES idea of a joke and stuffed something down the filler tube.

GOD BLESS THE UNITED STATES MARINE CORPS!!!

wow, I know the pressure was

wow, I know the pressure was tested at the rail and passed along the info you sent. thanks, will let you know when I find out.
GOD BLESS ALL OF OUR VETERANS, EVEN YOU BB.
it's 85 deg here think we can rule out frozen lines.

You’re welcome brother. Glad

You’re welcome brother.
Glad to help you out.
Help you out anytime.
You can count on it.
Semper Fidelis remember?
Couple of things.

First. You never posted your granddaughters location, so I had no way of knowing she was in 85 degrees.

Second. is as veteran its hard for me to understand why you don’t understand the “Unspoken Truth” that veterans know and understand.

In other words when I say GOD BLESS THE UNITED STATES MARINE CORPS I’m also saying GOD BLESS ALL OUR ARMED FORCES AND VETERANS, without having to say it.

Shouldn’t have to spell it for you this way.
You should just know and understand it.
It was decade’s ago brother.

Maybe it was you who had my back up there in your F-100 Super Sabres or Douglas A-4 Skyhawk.

Just naming two planes off the top of my head.
We both know there were more planes

Maybe it wasn’t you up there.
Doesn’t matter my brother.
Point is we were all on the same team.
Doing what we had to do.

GOD BLESS THE UNITED STATES MARINE CORPS!!!

Weasel, Had a really busy day

Weasel,

Had a really busy day yesterday.
Meant to post this along with my answer but just forgot.
Sorry brother.

The fuel psi reading you got (160) is WRONG.
Proper pressure on the said vehicle is 55 to 65.

Reasons you got a pressure of 160:

Fuel pressure regulator issues.
Cheap gauge.
Gauge is defective.
Gauge is NOT designed for electric fuel pumps.

GOD BLESS THE UNITED STATES MARINE CORPS!!!

you are correct. got the

you are correct. got the reading 2nd hand and they added a hundred to it. thanks

You're welcome

You're welcome brother.
Anytime.
Keep me updated.

OBVIOUSLY the second hand information you’re getting is coming from an UNQUALIFIED FOOL. Why else would he (or she) add 100 to the fuel psi?

That raises the question of WHAT ELSE IS THIS UNQUALIFIED FOOL IS GETTING WRONG?

Codes for example:

Is the UNQUALIFIED FOOL ASSUMING that there are no codes because the check engine light is NOT on?

Most likely the UNQUALIFIED FOOL DOESN’T KNOW TO IGNORE the check engine light and just do a scan.

It’s your granddaughter brother.
Stop relying on second hand information from an UNQUALIFIED FOOL.
Get over there and check things out for yourself.

GOD BLESS THE UNITED STATES MARINE CORPS!!!

the fool of which you speak

the fool of which you speak is my son. the scan has been done even though there is no lite. my son is a very busy guy with a lot on his plate and the mechanic is his son in law with his own shop and trying to fit this in between jobs. he is very competent and will get it right sooner or later. glad you are so patient / brilliant and such a superior mechanic with the time to criticize. none the less I bow to your knowledge and expertise. the car is in good hands, just wanted your opinion on possible cause but can do without your demeaning remarks. forget I asked.

Wild weasel, Have no patience

Wild weasel,

Have no patience for incompetence and stupidity.
Especially in this business.
ONE bad mechanic makes us ALL look bad.
Sorry but you're partly to blame here brother.
You NEVER posted that the mechanic was your son.
NEVER NEVER would have said what I said had I known it was your son.
REALLY SORRY BROTHER!!!

GOD BLESS THE UNITED STATES MARINE CORPS!!!
