EMERGENCY - WHAT HAVE I DONE , DIY!?!?!

help! ive broke my car FUEL PUMP RELAY FUSES??
after the replies from my last post about the problem of my car sometimes losing power i decided to try some diy with haynes,
it was suggested it may be my fuel pump relay
i took out the ashtray to get access to my fuses and relays, saw that there was a fuse for the fuel pump took this out and wiped it etc made sure it was back in firm
i then pushed my hand up to the back where the relays are and pressed them all down in case one was loose
then i started the car up...
but now instantly the idle is searching and goes very low and the car is very hesitant on acceleration!!!!!!
what have i done,
i have recently had the Idle air control valve cleaned and the oil pump replaced etc it was perfect unil i did this, this evening!
have i dislodged something broke it or what!?!?!
please please help

Hmmm. Sounds to me like you have found the culprit.

The relay generally fails because of dry solder joints... they crack with age, weakening or breaking the contact. My guess is that yours was on the way out, giving occasional failures when the relay got too hot, everything expanded and the joint came apart. Its possible that by pushing down on the top of the relay, you have caused it to flex and therefore exacerbated the problem. Aleternatively, you may have shifted it in its socket, giving a bad earth.

I'd be on my way to get a new one and have done with it. In fact thats exactly where I'm going this pm. My 940 refuses to start and my no 1 suspect is the FPR.

Hope that helps, please post back to let us know how you get on.

Cheers,
Paul.

Also, this snippet (Copyright Peter K Milnes) may help for accessing the relay:

You must carefully pull off the small trim around the cigar lighter and remove the two screws in the top and bottom corners that are normally covered by the small trim. Then you can remove the cigar lighter tray and gain access to the relays.

DONE IT!!!!
i took it to the mecahnics first thing this morning and as soon as i got your email i phoned down to ask them to check this first
they phoned me back and said there was a current going to it so it was fine, not convinved i went to volvo and bought both available fuel pump relays for the 940 ones green the other white
this evening i followed the instructions above replaced the relay - mine was white = cheaper of the 2 and its perfect - better than before on start up etc!!!!!
volvo will take back the unused green relay which is just as well because its 50 quid.
thanks for all the advice at least something good came out of my tampering as i reckon your right i found my intermitent fault by making it permanent!!!!
Good luck with yours, let me know!

Well done you.

Looks like I was too cocky. Switching out the FPR on my car hasn't fixed my starting problem! That'll teach me to jump to conclusions!

Cheers,
Paul.

Looks like i was too cocky aswell,

took the car out this morning, first startup revs dropped to low, switched ignition off started again sat perfectle at 700 revs
started driving felt a little more sluggish than usual,
then when i stopped my oil pressure warning light is on!!!!!!!
after having a new switch and pump and changing to thicker oil it was solved how can it be back after replacing the fuel pump relay!?!?
nightmare!
ive put in some fortifier and a fuel system flush until i get down to the mechanics on fri.
any idea!??!!?

found this on brickboard....



"I've owned this car for 6 months with absolutely no problems except a noisy ps pump. Suddenly the oil light went on and i then heard the valves complaining of no oil pressure. After flushing the engine, replacing the filter, oil pump and associated tubes, pickups and valves, it still has the problem. From a cold start the engine will idle for hours, including running the rpms up, and the oil light stays off and there is oil pressure. Then a short trip down the road produces the light and valve noise. After a short cool down everything is ok. Sometimes the light goes on right from cold start up.
Answer: The o-ring on the oil pump suction tube in the oil pan has been pulled inward allowing air to enter. While the pan is off the two o-rings at the pan-to-block joint need to be replaced also. "

think this may be oil pump answer -
thoughts???
seems the same symptoms and tird everything i have.
