Which fuel injection system does your car have? The 1.8's L-jetronic FI actually has a "dual relay" hanging off of the battery tray that takes over the function of those two relays from the relay board.

If your car is D-jet (1.7, 2.0 original EFI) then Brad Anders has just about everything known about the FI on his website: http://members.rennlist.com/pbanders . He even has flowcharts for troubleshooting the fuel pump control system...

As you can see I moved the pump and added some new lines to old linevs where shorter and one cracked like a stale piece of bread so I put on some longer lines I had orginized and hung neatly but pulled them down for a better pic.

If the fuel lines were as bad as you say, you need to pull the tank & replace the lines there.

The filter you have on there is a cheap low-pressure one. Chances are decent that it will break up and get into the pump...

If you look carefully, there are tabs with letters next to each port on the pump. "S" stands for (the German word for) Suction, and is hooked up to the fuel filter and then the tank. "D" stands for Druck, German for "Pressure". That gets hooked to the driver's side fuel rail. "R" stands for (the German word for) "Return", and the hose goes to the "Y" fitting that goes to both the return port on the tank, and the fuel pressure regulator in the engine bay.

Clean the contacts for the fuse. BTW, the fuse should be red, not white. White is 8 amps, not enough for the pump circuit. The Cap'n

Good to know.. I just bought all new fuses and some extras I will toss a red in there... As this is a new car to me I have been going over all the electrical grounds hitting everything with wd'40

I am going to snap in a new fuse and take it for a spin

You mentioned wd40 everything. For electrical items with some oxidation, tarnish, and dirt, you need to very gently clean contacts off with fine sandpaper like 400 grit, then spray off with contact cleaner. You can get contact cleaner at Radio Shack/Fry's or at your FLAPS. Just make sure it's contact cleaner with no residue. Some have lubricants in them; you don't want lubricants.

When you're done with the contacts, they should be nice and shiny.
