I have a 95 2500 with a 350 under the hood. Sometimes it will start fine when it'* a cold start up, but if I shut it off and run in somewhere and come back out to start it again it cranks for a longer period of time than normal. Seems like a fuel issue because it hesitates a little and runs a little weak for maybe 5 seconds and then lines out jus fine... I basically jus use this truck for work...I bought it about 2 weeks ago for kind of a beater to keep the miles off of my other truck. Got any idea'*? Oh and I changed the fuel filter last week and put some injector cleaner in the tank

those trucks are the worst to try to work on because they got all the obd-2 sensors and circuits to break but you need a special obd1.5 scanner to see whats going on. i would start by checking to see if the fuel pressure is good but again you need a special adapter to put the gauge on. did you check see spark or check the plugs/wires/cap/rotor condition?

Looks like it needs some plugs and wires, but had to put a new battery in it yesterday. Seemed to help so far, but I'm still gunna check the fuel pressure at work sometime this week. Thanks for the idea'* man.

You should also check the fuel pressure regulator.
