this on the 82 with TPI

replaced the pump.. and its running. im getting 45 psi at the rail with key on but engine off... when i go to start the car it drops to below 30 psi and car runs for maybe 2-3 seconds then dies.... is there maybe air in the line? maybe i have a kinked line?

ive been trying to get it to stay running for maybe 15 mins and it still trys to run then dies... i dont know what else to do :confused:

when i have the key on but engine off i hear gurgling at the fuel rail.. you think maybe my fuel pressure regulator went out? CAN they go out? lol

i just wanna go throw the car off a cliff

Clogged fuel filter, clogged rail, bad FPR. Get an adjustable and see wat happens

I would say this sounds most likely like the FPR going bad as mentioned above, clogged line or filter would probably effect the idle whe in park/neutral as well. I imagine this could potentially be a computer problem of some sort as well. I would also see if it has any codes being thrown and what those codes are, see if you can get your hands on a scan tool and keep it plugged in while you are testing and see what you find out there. Sorry if this has been little help, but those are the directions I would go in.
