Dear friends,
my trusty 940SE left me on the highway...
I cannot hear the 2 sec. hissing of the fuel pump when turning the key.
Back at garage I checked the usual stuff:
- removed one spark plug and crancked: OK SPARK
- checked the radio suppression relay: OK
- checked the fuel pump relay: PROBLEM
I have the green relay (Volvo 13622914) mounted on the passenger feet comp. (remember that the 940SE is basically a 960 with a 4 cyl.)
THE RELAY TEST OK, inside the green plastic there are 2 relais, both are operating ok. But just in case I tried to SWAP with a NEW RELAY but it did not solve the problem.
I installed the relay without the plastic cover and operated the relay "manually" with the finger: I could immediately hear the fuel pump noise and the CAR STARTED IMMEDIATELY!!!
So I tested the socket and to my big surprise no power to 85 and 86/2 that should energize the coil of the fuel pump. No negative and no positive...
I do not have the electrical scheme to follow and I have no a clue of where to look for this.
Any help is greatly appreciated.
Sincerely,
Dave
