Fuel pump runs for 1 sec and car fires a couple of times but seems like it is out of gas. What's the next thing to check in the fuel area that maybe the problem?

Did you verify it was the pump or regulator which is attatched to the pump. Either way glad it's fixed. Just haven't heard of an actual pump going bad yet.

My guess is the pump.

I could be wrong but I think the fuel pressure regulator just keeps pressure in the fuel lines when the car isn't running, so that you don't have to wait for the fuel pump to build enough pressure to start. So if it goes, I think it just takes a bit longer to start, I don't know if it would cause it to not start.

It keeps the pressure regulated the entire time the pump is running.

did you replace the pump yourself? about how much does it cost to replace the pump?

Glad you got her running!

didn't verify whether it was pump or regulator. car has 80,000 miles on it, just decided to change the whole pump assembly and hope it runs for another 80,000. did work myself, pump assembly was 319.00 and new "O" ring was 30.00. hardest part was getting lock ring off that holds pump assembly in. also learned a bad cam position sensor or bad crank position sensor will keep pump from running. bought a scanner and no codes present when initially troubleshooting. after getting car running i was curious to see if bad sensor would keep pump from running, so disconnected the cam position sensor and tried to start car. would not start, fuel pump would only run 1 sec. and stop. reconnected sensor and the car started up. pump location under the back seat is great, sure beats dropping the gas tank to change pump.

My Fuel Pressure regulator was replaced for the 2nd time this summer (under warranty). Car would start but only after excessive cranking ...

Glad you got it fixed and it's up and running again.

@ albiet good job replacing it yourself, plus you saved money :piggy: :2cents:
ohh...maybe because the crank position sensor was not the problem there was no code on the scanner. but I wonder if the sensor would send a signal to the computer before it goes bad to be able to diagnose a malfunction in the crank position sensor when is not starting..maybe

anyhow,
the main thing is that she's running!
I have a 2007 and I'm close to 96,000 miles, sometimes before I start my car I have the habbit to listen to that fuel pump buzz... incase she doesn't start then I might know why

to clarify my earlier post on fuel pump repair. after disconnecting camshaft position sensor to see if the code would come up, code p0340 came up. i'm assuming if crankshaft sensor malfunction that code would appear also. cleared code and have been happily driving ever since.
