I have had one issue that I need to address. When I picked the 94 KS4 up from the port, it took around 15 seconds of cranking to fire up and run. I dismissed this as protocol to empty the carb for shipment. Then I noticed anytime it sat for 4 days or more it did the same thing. I assumed it had a manual fuel pump but all my research said no, it has an electric pump. So the next time it hadn't been cranked for a few days, I turned the ignition on for 20 sec and then cranked it up. It still took 15 seconds for fuel to get to the carb and fire up. So I thought that didn't make any sense and I found the fuel pume and had my son turn the ignition on while I held the fuel pump. I didn't feel or hear anything. For further diagnosis I removed the fuel line after the pump and turned on the ignition while looking under the truck. No fuel whatsoever. I then hit the starter and immediately got splashes of fuel on the ground. I'm guessing there might be a safety that prevents the fuel pump from running if the engine isn't or if the starter isn't engaged. I'm planning on putting in a check valve for a short term fix but wondered if I'm on the right track?
