First an foremost. Thanks awesome site!
.
I have a 91vw Jetta turbo diesel
.
.
185k
.
.just replaced altenator.
.
.
when it gets up to running temp of 190
The engene will shut off.
during driving or just siting idol.
.
Im sure it has to do with FSS on the pump.
But what an why
.
.
Auto parts storess haven't a clue
of this fss.
.
.
NOTE: I've ran lots of cooking oil /have motor oil through this.
Replaced fuel filter after problem started.
.
If left to cool down will restart with no hesitation.
.
.
I HAVE CHECKED FOR VOLTAGE (I LOANED VOLTAGE METER OUT SO ONLY KNOW THAT THE LITE
COMES ON TESTER.
N RAN A JUMPER NO CHANGE.
.
I KNOW IT STUPID TO ASK WITHOUT
CHECKING FOR PROPER VOLTAGE.
.
THE BIG QUESTION IS IS IT POSIPLE THIS FSS WENT BAD AN WERE AN HOW MUCH DO THEY COST.

I WILL GET A VOLTAGE METER AN CHECK BEFORE I REMOVE TO REPLACE FSS.

.THANKS AGAIN.

 

dont know much but does it mean Flexible Service System?..

 

I sorry after reading lots of posts about fuel problems on this site.
.

I learned that a fuel shut-off solenoid was refered to as FSS
.
.
so i made the mistake off assuming that anyone who was looking
to help me was already familiar with that terminalegy.
.
.
there is a round srew in plug on top left side of injection pump
With a single wire attached.
.
.
this i Assume to be the FSS.

Mite i be correct?

Thankz yal
