fuel pump relay: to run or not to run?

[Whistlerskipro]

Hello to all again Peter here hoping to leave tomorrow as planned but something came up again.

I just picked up a new FPR, and it is half the size as the one I had in before as well having 4 plug rather than 5. I know things are getting smaller. After changing my fuel pumps and filters the car just won't start when hot. So when I put the new FPR in and turn ignition on without cranking it internal pump runs continually as opposed to the older larger relay that runs for a second or so. Which should it be?

Should run for a few seconds.
However you can drive the car back to BC with it running...just remember to unplug the relay!

FPR= Fuel Pressure Regulator......different!

Thanks, I was somewhat suspicious with the new relay half the size and was surprised when the internal pump ran continually. One of them wasn't doing the job. The older relay is 2" as opposed to the 1" they sold me today. It that what it spills be 16v?

Yer talking like me now, but w/ a little too much Yoda mixed in...

Does the new Relay (FP Relay) have a schematic on the side like the old OEM one do (did)?

In a nutshell, and absent any other info, your four post Relay is for the earlier VWs.

Yes the new one has a schematic with th #'s 87 86 left 30 85 right. The older one "less than 2 years old" KRÃCKER
24.1400.20 kraftstoffpumpenrelais. I believe I paid a lot more than the $9.00 today.

Took the ride in today to the Dr. Office. First time in 5 years. Problem was vacuum leaks and bad O2 sensor.
