hard to start 305tpi went cold,spray gas into tpi ,then it starts run up,after warn up ,starts on it own...
Does priming the fuel system by turning the key on (without attempting to start) for 3 seconds key off then on for 3 secs then off then on for 3 seconds then trying to start help? Make sure all the cluster lights come on when cycling the key. In a perfect fuel system the fuel pressure will stay above 30 psi for weeks. There is a one way check ball in the pump and the pressure regulator closes with the engine off preventing fuel from depressurizing in the rail. If one of those fails then a very hard start condition can occur but may not be your issue. I say this because its a simple test and you stated starting fluid helps. In the end your either not getting enough fuel or too much air.
