Here is the situation, I went to start my truck to take it over to a buddies to hook up the FP gauge again, (needed a new fitting after the Air Dog install) and it won't start. It started to fire then I stopped cranking and it shut off. Now it only cranks but will not fire. I tried to hook up my smarty for codes but it will not connect, not sure why but it keeps telling me to turn the key off, then on, then says connecting, then back to the key thing. The Air Dog is not pumping anymore, normally you could hear it when you first kicked the key but now it just sits there. The key trick has never worked for me, not sure why but I have never gotten it to work. There are no fuses blown, nothing unhooked, everything looks good. Anyone got any ideas?

In the last month or two I have added the Air Dog, SB DD 3600# clutch, and Smarty. Truck has just over 31k on the clock now and it ran fine yesterday, no signs of anything on the way home last night.

Any ideas?

 

the smarty is having a problem communicating with your ecm. when it keeps telling you to turn key on /off/on/off. communication link is not established

hope this helps

 

Any ideas why this might be? I figured that it was having a problem connecting because it kept telling me that no matter what I tried, read codes, change tune, etc.

All relays and fuses are good, I have the batteries disconected currently trying to reset the ECM.

 

I think your tipm took a crap on you. dealer will fix under warranty. you can try unplugging the main connector on the underisde.

 

Got it to start, there was a bad ground on the drivers side battery.

 

and thank you for calling. that was very courteous of you.
