The only problem I'm having now is that it now sounds like my fuel pump is not getting full power. I looked at the FSM and looked at what it said. It said to check for continuity at a the pump connector terminal. And assuming I did it right, (continuity means using the voltage scale and touching one probe to each of the two terminals and checking for voltage, right?) Then yes I do have continuity.
The pump does work but it sounds like it's pumping slower and is not as high pitched as it should be at full power. What could cause this? Bad ground?

I'm assuming it is the stock unit? Considering the car is 20+ years old, your pump could be going bad. What was the voltage reading you were getting?

It was around 9 volts. And no I've done a turbo swap and it's a walbro 255.

Anyone? Please help. So close to being able to drive it again, after not beaing able to for a month or so.

if you're going to put a walburo pump in, i don't understand why you wouldn't take the little extra time to rewire it so that it will get the proper 12volts. after all these wires are 20+ years old.

right now i have a wire coming directly off the battery, through in-line fuse through a new relay to the fuel pump. ECU turns on the relay.

It was working fine. Maybe sitting for the last month or so while I've been trying to fix it something happened. Maybe I accidently broke a wire. IDK. But I wasn't exactly sure how to go about rewiring it. I was looking at some things I found in the archives the other day. And the only thing that's bugging me is trying to keep the Fuel Pump Resistor Relay thing. I may just try what you said at least temporarily to see if that solves the problem. What size fuse did you use?

I've got a relay and fuse and some 12GA wire. I've looked through the FSM and I'm having trouble figuring out what wires are what on the harness for the fuel pump on my Turbo swapped '91. If anyone could shed some light on that for me that'd be awesome.

There should only be four wires at the connector to the fuel pump. White/Red and White/Green are for the fuel level sensor and low fuel light. Black would be the ground and Blue/Green is the voltage wire.

It's probably a 15amp fuse that's in there, i'll double check next time i'm out there.
