Need Help with EFI to Carb Conversion
I hope I am posting in the right section. I need some help with a project.
I have a 98 Z28 with LS7 block based 427. I am taking off the FAST intake setup and going to a Demon carb and Edelbrock intake. It came with a MSD ignition/timing controler. I am bypassing the ignition and fuel injection harness, but want to leave the factory computer for other functions. I installed a "Race Pumps" fuel pressure regulator designed for use with an efi pump and carb. The (racetronics)pump is fairly new
After setting everything up the fuel pump seems to quit pumping after intial startup. When I turn the key on. The fuel pump initializes and the pressure gage reads correctly, then goes down quickly. Then the carb will run out of gas in few minutes and the engine shuts down. I can turn the switch off and back on the it does the same thing.
Also the cooling fans do not come on.
I am not sure what to do about the pump, but I guess I can put a manual switch on the fans.
Any help would be greatly apprecated.
