my truck tries to start but then just stops and if you leave the key forward, in start position, it keeps turning over so my guess is it tries to start , hits the cylinder and missfires and thats what it says on the code, multiple cylinders missfires, cylinder #4 missfire, cylinder #5 missfire, and all this from putting smarty on sw3 so not sure if i had problems and putting it on advanced timing just kicked it over the edge or what happen but it wont start and im taking it to dodge dealership tomorrow any thoughts?

 

can you hear the lift pump kick on do you have a fuel pressure gauge? sounds like a bad lift pump to me

 

yea lift pump kicks on, its been real cold lately and glowplug lights come on the dash and it started before i put the program on

 

did you try clearing the codes with the smarty? also maybe disconnect the batteries for a half hour or so and go from there.

 

Put the truck back to stock, see what happens.

 

crack the fuel filter cover to make sure you are getting fuel from lift pump, if you are, inspect fuel filter for blockages including gelled fuel. 911 fuel stuff in filter housing, and in tank and let it work its magic, fresh filter when closing her back up will not hurt either.

 

yea its not the timing its just 2 cylinders have no compression at all thats why it wont start time for a rebuild

 

howd you blow 2 cylinders?
