My 1990 SSE started for the first time yesterday since purchase.
Initially I thought it was a fuel pump problem but it turned out to be the ground wire on the factory harness that connects to the fuel sending assembly. Luckily, I was able to return the new fuel pump that I purchased because it didn't even work. It was worth the time to drop the tank anyway because the lines in the sending unit assembly are horribly rusted and crumbled in my hand. The new part is on order.
I have observed one strange thing though: when the ignition is turned on, the fuel pump does not begin pumping. It'* only after the key is in the crank position that the relay clicks and the pump turns on. This makes for difficult starting. In my wiring diagrams, it shows a "fuel pump prime" thing. The wire from this is connected to the same wire (gray) coming from the relay and going to the pump. Although the fuel system is only temporarily connected, (the tank is still on the ground and some hose clamps are omitted due to the lines breaking) I wouldn't expect the pump to behave this way. What/where is this "prime" thing?
