hi,
i replaced the fuel pump relay on my 87 k10 (with 350 motor, throttle body ignition) six months ago. the truck was running at the time. it's been sitting for over five months.
now it has no spark, and the fuel pump isn't running.
if the fuel pump has failed, would that also cause no spark?

also installed a new coil and ignition control module. fuses are good.
i'm ok with replacing the fuel pump for reliability, the current pump has a lot of miles on it. but if that's not going to solve the no spark problem, i'd rather not drop the tank.
thanks for any input.
