88 tpi hard to start only in the morning
in advance any ideas are apreciated. well i have been trying
to track down a hard start.Every morning i have to crank for at least 1min, but it all ways starts. The entire fuel system is new, and the ignition has had everything replaced. It did this with my tpi and now with my hsr .
Im out of ideas. 43psi fuel pressure on 24 lb injector has strong spark on all. Igot these reading in the morning, a couple diferent times as it is turning over to start but no start.

Re: 88 tpi hard to start only in the morning
Its prlly your cold start injectors since you deleted them becuase the hsr doesnt have the places made for them. thats still strange though cause i have the mini ram without the cold start injectors and it starts rite up. do you have the MAT (manifold air temp, i think thats the name) sensor installed somewhere in the intake?

Do you have any noid lights? Test to make sure you're getting fuel the injectors and a signal. I got the pcm for less chip but the throttle response is horrible with it installed

Re: 88 tpi hard to start only in the morning
I have the exact same problem on mine. Although it doesnt take me 1 min. to start it I have to crank it and crank it and crank it before it will finaly go. After the morning warm-up it runs like a champ, I can turn it off for 1 min or 2 hours and it will pop right off if I try to start it, only happens in the morning.
Can't for the life of me figure it out. Iac and tps are set dead on, great fuel pressure, brand new bosch 3's, MSD everything, etc, etc.
