Hello my name is XXXXX XXXXX i would enjoy helping you with your problem. This is a ecm no data code. FIrst thing i would do is ck all your fused that say ecm and also ck the fuses at the battery box, there is also a ground fuse beside the ecm its self. CK all of the and if the unit still will not start your probably looking at the ecm being bad internaly. Also you need to ck all the wiring around the ecm and all your connectors making sure they are not rubed or broken..

i check all fuses and wiring before . all i need to know is if something else like soleniod for fuel or injectors is bad so i dont smoke a nother ecm

NO if your truck is coding this it is your ecm since you have ckd your wiring. Also your ecm controls your injecors .. The fuel pump and the injectors wont cause you to smoke your ecm. The ecm has to be the right on for your engine serail or the engine wont run .
