Remote start worked fine prior to getting the truck tuned by EFI live, there are no codes, no CEL and the hood switch is not faulty. The weird part is when I try to do the remote start, it flashes the lights, applies the brakes and primes the fuel pump then nothing after that. I have searched high and low for this issue and it seems to normally affect the diesels but not the gas trucks. I am at the end of my rope here, the guy who tuned it is not offering any help. He has basically told me its not his problem and has stopped responding to my messages/phone calls. The odd part is this guy is very well known in the industry......I just want my truck back the way it was.

PS: I found this post on here regarding this issue:

"I would bet that it is the injector flow rates that need to be read from the GPM and flashed to the ECM.

From the home screen on the V2.
F2(tune) > F2(injectors) > F1(read GPM inject) > F4(program ECM inject)

That should do it. I have done it once. At first it didn't seem like it worked but, I just shut the ignition off for a few seconds and started it with the key, then off again, then it started with the remote"

Any help at all regarding this would be much appreciated !!!!!
