ok, So heres the deal, i replaced the strut on my acclaim and when i dropped the car to drive it out of th garage, no start, turned over key, fuel pump did not kick in, so ok, fuel pump is gone, no biggy, got a new one, put it in, went to start car, new fuel pump didnt kick in either, so we bench tested it, and the new one ran just as good as the old one did, to find out, the fuel pump isnt getting any electricity, So we have done lots of reading on here and got wireing diagrams, we have searched the wires, we DID find a few corroded wires, but we fixed those(solder then shrink tubeing). The relay is only clicking once and a while, not everytime we turn the key, On this diagram ( http://autoforums.carjunky.com/upload/Acclaim.jpg ), there is the wire that goes to the fuel pump, there is a connecter in that wire somewheres, we think it might be here, but we cannot find the connector at all, does anyone have any ideas or know where this connector can be found?

I know it’s hard to see in that diagram but the only other connector desides the relay and the pump shown; is B/H conn 24; which stands for bulk head connector, terminal 24. That’s one of the large connectors on the firewall, going through the firewall. I’m not saying there isn’t anymore but that’s all that’s showing. I wish these older diagrams would also give locations of splices and connectors like a lot of the newer vehicle diagrams do; but that would make things too easy. LOL
You probably already know this but the fuel pump will only cycle on for a few seconds when the ignition is turned on, for what is called a prime cycle. The prime cycle only lasts as long as the check engine or power loss light is on before you start cranking the engine. That’s another question does the check engine light come on when you first turn the ignition to the run position?
The PCM will only command the pump, fuel injectors and primary ignition coil back on via the ASD (auto shut down) relay after it sees an RPM signal. So do you have a consistent spark during cranking?
