the car starts then stalls. i suspect fuel presure problem,, how much presure should i have? initionally it had a crushed fuel line, the car was repediatly tried to start that way, i replced a fuel line, now i have about 30 psi, and pumping real strong though the return line, maybe a blown regulator?? thanks for looking

pressure should be 3,0 - 3,4 bar which is ~ 42 - 48 psi. what happens when you try to block the return line?
