I am in a time crunch, trying to get her back running by tomorrow. Went to do a tune up on my 87 K5 with the 350 TBI. I installed a new fuel filter, cap, rotor, plugs and plug wires. Put everything back together as published, and she'll crank, but not start. Running when I started the project...now not so much. Checked the spark from a few wires, let's just say I felt it... Pulled a plug, it was dry as a bone, turned it over without the plug in, no fuel to be seen. HELP!!!!! I rechecked the fuel filter i put in, fuel there, no problem. I had crank times of four-five seconds before the tune up (or tune down)... Is it the pump?!?!? Thanks for the replies, sorry for not searching!
