So far it has been an on going issue since July hours or weeks don't even matter at this point. I will go to see if I can find any other numbers the engine the Tech Mate Scan tool tells me the ECM is MEFI -3

Yes spray pattern is really good cone shape I don't think I have a fuel issue as I have checked the fuel pressure coming out of the HP pump and it it is a steady 29-30PSI the TPS reading was running I will have to go back and check the IAC reading if it starts LOL
the plugs are all new AC Delco matched to the engine the problem has been on and off but has gotten worse sometimes I can start it sometimes it's like it wants to start but won't if I start it it runs what appears to be fine if I shut it down and try to restart no go.
Motormanfuelinjectors they matched what I needed perfectly I just repaired the TPS had a bad pigtail it now reads .04 at 0% throttle and 4.92 at WOT I have to go back and check the IAC as I replaced that too.
