OK, I am kind of at a loss here and hope I can figure it out with y'alls help.


Truck is running very good. When cold it starts right up and runs fine. However when I get it back after driving and it is warm I shut it off. Then I try to restart it. It sort of tries to start and then dies. Try again and same thing, it tries to start but real quick dies. Then on the third try it just cranks over and doesn't even try to start.


I pulled the codes and it is either showing an 11 or just continuously flashing indicating no error codes. I then pulled the EFI fuse to reset it, and then jumpered the fuel pump to B+. no luck.


Its got brand new plug wires, rotor and cap. NGK's. PLugs look great.


Anyone got any idea what is going on? Or what to look for? Appreciate the help very much.

 

OK, I'm reading that this might be related to the temperature sensor, the ECT that sends the signal to the ECU. Have to test or replace.

 

OK the temp sensor is reading ok. I unplugged the cold start injector and cranked it and after a little bit it started. Ran it for a bit, shut it off, and then started it again and it started up just fine. So, I guess it has something to do with the cold start injector. Maybe its leaking or turning on when its hot.

 

OK anyone have a good cold start injector?
