I recently purchased a rebuilt unit from PartWerks in chicago. It was only $100, with a $50 core charge, but they were a real hassle to work with. I ended up having to return two of them (one didn't generate pressure, the other had a bad check valve) but the third one is currently working beautifully in my car. I had to call way too many times for them to finally return the core charge, and will not use them again because I personally hate dealing with the run-around.

OK, now we're getting somewhere!!

First, can you hear the pump run? It should "buzz" for about 1.5 seconds when the key first goes from "off" to "on", and the pump should run the whole time the starter is cranking or the engine is running. If the pump does not run, then go through the pump troubleshooting flowchart on Brad Anders' pages above.

Make sure the pump is hooked up correctly--inlet line from the tank to the filter to the "S" port on the pump; "D" port on the pump going to the right-side fuel rail; "R" port on the pump hooked up to a Y fitting that goes to the return line to the fuel tank and also to the fuel pressure regulator.

Make sure you have no kinked fuel lines. (I know I keep saying that...) Especially on the supply side.

Loosen up the jam nut on the fuel pressure regulator, and screw in the screw on the end. Jumper the fuel pump relay to force the pump to run; see if that brings up the pressure at all. Keep a count of how many turns you have given the screw (or bolt) so you can get back to where you started if necessary. Spec pressure is 29 PSI any time the pump is running.

Make sure the plug on the pump is plugged in correctly. If you don't have a plastic plug body that slides into the connector on the pump, the wires may be switched. I believe you will get (near-?) zero fuel pressure in that case. If you think the wires have ever been removed from the plastic plug body, you might try switching them around as well. (More difficult--perhaps jumper wires from the plug to the connector on the pump just for testing?)

I believe any pump that delivers enough pressure and volume will work--but you will have to work out how to plumb it and how to plug it in.

I have a fi pressure gauge set up and have tried cycling the pump several times. No pressure is registering. So, I adjusted the regulator to build up more pressure; nothing. I even clamped down the line from the regulator to the return line; again no pressure. The strange thing is the pump is energising as you explain for 1.5 seconds or so. I double checked for kinks and there are none. I know fuel is going to the pump, because I changed those lines last week. The plastic plug body is still all nice and intact. So, I don't see it being mis wired. I guess I could see if I can plug it in the other way. Would that hurt it?

Also, I checked compression on 2 of the cylinders and they were right about 120-125 lbs. Is this good. Should I check the other 2?

Problem Solved!!!!!!!!

To make a long story short, someone had reversed the fuel in and fuel out lines in the engine compartment. While I was under the car looking at the lines, I decided to double check everything seeing as I was about to take out the pump to replace. When I realized the supply line was linked straight to the regulator, I realized there was a problem. I swapped to two lines and what do you know? Fuel pressure!!! I just got back from replacing the 20 year old tires. My car is finally on the road. I still need to properly time it, but it's running pretty well. Thanks again.

Isn't the first drive great. I made a first long trip over a month ago and I still remember like it was yesterday. Have fun!

Thanks. I still have some fine tuning before I'm going on any long trips, but it's exciting none the less.

Glad you got 'er running without too much money!
Clean looking car, BTW , very cool -
