Hi Machineman,

I wonder how many Volvos hit the junk yard for a bad fuel relay or RSR either of
which can croak your car outright, (easy to fix) or worse, fail intermittently
and start working without notice (tough to diagnose a part that is working OK)
Relays are good for so many cycles and are like all machines, striving for their
Nirvana, a stable busted state.

One way Blindboy can catch an intermittent fuel relay is to put his DC voltmeter
on F11 and when his car quits, see if he lost 12 volts there.
That might be good if it quits every five minutes.
In my case the car would either quit outright
and/or run very ragged requiring you put some foot on the gas to prevent a stall.
This problem would come and go, maybe working for months before failing again.

Cheers, Bill
