i converted my tbi to carb, im still using the tbi fuel system. I left the ecm plugged in so the pump would still work. I used a mallory reg with a return line so im still using the sock lines, tank, and pump(pump is about 6 month old, walbo 190). Hears the ploblem i am having, my guage show that when i turn the the key right before start, the pump comes on for a second and primes the system and then turn off like its supposed to, then i start the car and get no fuel presure at all, guage reads 0psi. the car will run till the bowls are empty then die. i checked fuel pump relay, and fuse, both still good. this just happened to me this morning, i have been using this setup for about two months with no problems?
