1998 z71

Asked by Jan 21, 2017 at 11:27 PM about the 1998 Chevrolet C/K 1500 Silverado Extended Cab SB 4WD

Question type: Maintenance & Repair

I have a 1998 chevy z71 5.7. My fuel pump and
injectors were working fine before i changed
motors and now the pump isn't kicking in. I put a
new relay in and checked all the fuses  and put a
new throttle body, injectors and all gas line on it
and it's still not working. What could be the
problem?

Your probably going to have to start tracing the power wire back to the fuel pump. A test light would be handy. I would start at the fuel pump power wire, see if power is there. A lot of times it is a ground back there.
