Seeking info on trusted aftermarket fuel pump relay

Post by JimBee »

I checked the "trusted aftermarket post", very useful!
There was one fuel pump relay vendor (to avoid) I didn't recognize.
Also a search of the MVS site doesn't turn up info. I seem to recall somebody resoldered one that had failed, that post didn't turn up.
So, Volvo only? At $100 phew!

abscate Thanks for the offer.

The ones I've seen for the 850's are all 103's. Are the 99's same thing?

ProParts is suspect, and friends don't let friends URO, ever.
I bought some once labelled Febi, turned out fine. Haven't seen any lately.

I got the 93 started with a known-to-be-good relay from my daily driver and it ran just fine—for about 100 yards and then died. Crank, crank, crank not even a meek little pop.

HOWEVER, the check engine light was now on, which it hadn't been when the relay flatlined, so that meant there was a possible clue in the code blinker box.

Which there was—camshaft position sensor, 2 codes. I happened to have a spare Bosch in inventory, finessed it in and voila! It seems okay now. Starts like it used to when the first plug fires.

Sometimes it takes a while for it to tell on itself. Glad you didn't have to dig any deeper.
I carry the jumper wire setup in each car; the new spare relay is in the ready position on the shelf.
