Hi I'm Anthony. I have a 1994 k1500 with a 350 engine. Since I bought it a few months ago I have replaced the plugs wires distributor cap and rotor button. For some reason my truck will only start if I use start fluid. Once it starts it funs but seems like it is misfiring. Any suggestions as to what the issue may be? I tried replacing the ecu but that didn't fix issue either.

 

Welcome to the forum. I'd check fuel pressure both w/ engine running and w/ key on and engine not running. Then post questions in the forum section for you truck where you'll get more views.
