Where is the fuel pump relay located on an 1999 S70 T5?

I think your '99 should be the same as my daughter's '98. It is under the fuse box cover. You need to remove the 4 T-25 torx screws and remove the cover to get to it.

Just returned from O'rielly with the T-25 driver. Any idea where to find info on replacing the relay or by passing it to test it. I have seen postings about use of a paper clip but not enough detail.

This thread should tell you pretty much everything you need to know.

Found the relay, did the paper clip jumper and the engine now runs properly. Will get new relay tomorrow.

A big thank you!

I'm sure the relay swith is under the hood, but I cannot distingush whick relay it is. Volvo parts says I need the number on it before they know which one it is. Does anyone know how I can tell which relay it is.

The relay board can be resoldered and put back into service. We did this three years ago in my wife's 850 and not a peep out of it since. Pop the cover off with some fine screwdrivers and take a look.

If you don't solder, ask a friend to try. Ours was intermittently failing especially when under hood temperatures were higher; even when the engine hadn't run and the car sat in the sun.
