Hey Guys,
Twice in the last few weeks the 01 VDP 94K after being driven for approximately 30 minutes, followed by sitting at idle in park for 5 Mins has studdered and stalled. Immediate multiple attempts to re-start produce very rough idle, no response to pedal and subsequent stall.

First time - after a few hours it started and operated normally, although the car was not driven.

Yesterday - I kept reproducing the same result with one 10 minute period of normal operation (in park) followed immediately by the same rough idle and stall.

I attempted to turn the key while listening for the pump and heard it once out of 7 - 10 attempts. (Once pump is primed will it cycle every time key is turned, or only after a period of time?).

Car had fuel filter replaced yesterday morning (while doing tensioner job) so this has occured both prior to and following filter replacement.

I swapped one relay in the trunk - but had no change in symptom.

Question: can a fuel pump fail intermittently? And, any other thoughts would be helpful.
Thanks in advance.

 

there's a schrader valve on the fuel injection rail for you to connect a fuel pressure tester, it should be around 40psi on cranking - pump should prime every time. It's a common enough fault (fuel pump failure). Plenty of posts about swapping it out.

 

Yup could be the lead wires so when u ****** it out check those too. It will be an all day project and make sure u are careful with the fuel lines at the tank.

 

I'm with Sean. Check the fule pressure with a test guage before you even consider tearing out the tank. It is not much fun!

 

Had the car on Snap-On fuel pressure monitoring and after running for an hour and 10 minutes went from 40psi to 15 sputtered and stalled. My Mechanic had a great read out showing the amps and current draw. New Pump going in tomorrow.
