ok...had fun doin the egr delete...had more fun doin the funky lil fitting for the hpop...now a week later ...it wont start..it acts like it wnts to..but just wont take hold...my code reader wont pull codes off it..it ran fine..then one morning it had a hard time starting it bucked n luged..turned it off checked the fluids every thing ok started it n it was jus fine ran smooth..all day of starting n stoping no problem...then the next morning wouldent start..it wants to ..fires n dies as soon as the starter stops...any help would be great...

 

May or may not be helpful but I know when doing EGR deletes there is a ground that is connected to one of the studs that holds the intake manifold down, it is on the driver side, all the way back towards the firewall. I've heard if that is left off it can cause similar issues, though I don't think it's your problem since you start fine one day and not the next. Definitely sounds like a loose connection somewhere, but not something completely disconnected. Make sure your connections at the FICM are TIGHT.

 

Is this a cold sstart issue or warm start or does it happen at anytime?

 

it would be a cold start problem...it started rough one mornin then the rest of the day it was fine then the next morning it wouldent start at all..i have double checked all th wiring including the ground wire...it hasnt started since...it wants to fire but just wont

 

Check your FICM voltage. I'm 98% Sure It's dead
