I have read everywhere trying to find a similar problem and can't find one. So my truck is hard to start when it's cold,if I shut the truck off after it starts it will fire up no problem. But if it sits for a few minutes it's back to hard starting again...so this is what gets me considering I thought it was a fuel pump,if I let it sit for 3 days or so it will fire up better then ever first try when it's cold..dizzy is good,Afm is good,injector o rings looked good,new battery and starter, new igniter and coil,new cts,new fuel filter,new fpr, all I can think of is the cold start timing switch or the injector itself
