1993 Saab 9000. No injector pulse. No fuel pressure. I can jump relay for pump and it works. It had no fire or injector pulse but after replacing the crank sensor I got the fire back. Any ideas on what would cause no injector pulse?

are you getting ground to the fuel pump relay ?

if the crank sensor is bad you will lose injector pulse

how many miles

A bad ecm not sending ground will make you lose injector pulse ?

do you a have a scan done , any fault codes ?

Please let me know

Thank You
