I replaced my blower motor on a 1996 Chevy S10, unfortunately I had to remove Computer for clearance. Now truck will not start. I can turn on and hear fuel pump running, but still does not turn over. I have no pressure on fuel rail. Could this be caused by/if the computer is not sending signal to pump fuel? TRUCK WAS RUNNING AND STARTING JUST FINE B/4 I DID THIS. Please help, Thanks!
