Searched all fuel pump relay posts.. found similar but not same issue. I'm very impressed with the advice on this site, so hope you folks can help me.
Problem: The ubiquitous, 94 855 Turbo -"cranks won't start", after quitting dead at 30 mph when running fine with no problems.
Read every related post and completed all suggested diagnostics.
Power checks ok to fuel pump with VM
No fuel pump sound when cranking or listening in rear compartment
103 switch wiggles like a hula dancer in that socket, is that normal?
One time, got no power to pump, wiggled and seated 103 again, power read positive again.
Unique issues:
1. Cannot remove 103 Fuel Pump Relay (every post says, "took it out to check corrosion, broken solders, etc, yet no one mentioned not being able to get the puppy out at all?) I think I understand the snap connectors, but there is no space to release the left connector on 103. What's up with that? ...I'm fairly adept at solder, but really need to get it out first...
2. Stoopid me broke the 90 degree connector removing fuel pump pipes, stuck tite with 12 years of committed service, so now I cannot proceed to diagnose until I replace. Plastic snapped at smaller bore plastic inserted into rubber hose. I am unsure whether it is the pressure pipe, or return pipe. (it has yellow tape on it if that means anything to volvo repair pros, and not just a preference to previous owner.!) The electrical connectors also have a yellow tape strip, but not the second fuel pump pipe.
I have Chilton manual, not helpful at all in identifying which hose is what.
The dealer wants 75 bucks each for the pipes, I'm trying to get used locally.
Have a guy who will sell me pump, harness, both pipes, 02 sensors (it's time anyway) and fuel pump relay switch for $250, off a running 850 turbo sedan. Looks like a great deal, (verify?)but I still won't know how to get out that @#$%! 103. I'm also not sure I'd need the whole fuel system if it is just the relay.
Last, out of curiosity, why is my special little fuel pump relay switch green-when everyone else says the 103 is red?! (and online pics show it red)
thanks in advance-

ps yeah, i'm a girl but I wrenched with my dad since age 8. Just used to chevys and fords... only been a Volvo owner (obsessor!) for the last 8 years.... still discovering.... for example, I'd gladly race you removing a starter from my F-250 pickup and this 850 turbo, the latter requires several bloody knuckles and the flexiblity of someone from cirque du soleil....(grin)
cheers!
