First off, my car is an 89 L98 TPIS intake manifold (honestly not sure which one), 24lb/hr SVOs, fuel pressure regulator, hedman longtube headers with true duals. I went out to start my car for work one day and it wouldn't start. I discovered I wasn't getting any fuel pressure to the rails, and after checking other things I decided it was a dead fuel pump. 21yrs old and climbing, so I just replaced my pump with one from Racetronix hoping it would fix my fuel pressure issue. After waiting over a week for it to arrive and being without a vehicle, I got it in and went to start the car. Yet again I have 0 fuel pressure. I've checked the fuse and swapped the relay with the fan relay. Nothing seems to work. The battery is dead so I tried this with jumper cables hooked up to another car, but still 0 fuel pressure. I need a lot of help and this is the only place I know that might help me fix my problem.

Thanks in advance for any help at all.

THE PUMP HAS A STRAINER SOCK ON IT THAT YOU SHOULD HAVE REPLACED AND ACTS AS A FILTER OF SORTS. IN YOUR THREAD, I SAW NO PLACE WHERE YOU CHANGED OUT/TESTED THE FUEL FILTER.

 

Ok. After another half day of troubleshooting and testing. I discovered I had 2 issues, and this was the reason it was so hard to track down.

I removed the entire fuel pump and assembly once again, and inspected all the electrical connections once again. There was a little black on the ground wire where it plugs directly to the fuel assembly cover that bolts to the tank. I cleaned that up and made sure it would make a better connection. Tested the pump after installing the assembly once again, and it worked perfect and was getting pressure to the rails. But when the key was turned forward nothing would happen once again. I swapped the fan relay with the fuel pump relay again, and the car started right up.

Hard lesson learned. Never get too excited about getting your car fixed and back on the road, and over look other potential problem areas when replacing your fuel pump. I probably didn't need a new pump, but it being the original I feel more confident in my fuel system now. And yes the Racetronix kit came with a new strainer.

.......cool

...so, bench test the other pump and if working, seal it up and carry on teh road in case of breakdown.

but it being the original I feel more confident in my fuel system now. And yes the Racetronix kit came with a new strainer.
....but, you didn't mention it....good you got it fixed and if possible, carry a spare relay too.....

 

All great advice and something I WILL be doing. Thanks very much for your input and help.
