Sometimes it cranks and cranks fine with no start. Other times it starts right away. I have good fuel pressure during start and no start. Injectors are good except during hard start then one doesn't light until the truck starts. The crank sensor is good and the cam sensor is good. There is no spark. This is as far as we have made it so far. Also, the truck runs fine once it starts.

Reset security system if no manual look online then scan for codes and check fuel pressure with a gauge. Auto parts rent it.

I will try reseting the security, but if it was security would't it be a constant problem. I have used a pressure gauge. Its constant at 45 I think until it starts then the pressure drops and restores once started. Whats the chances of it being the PCM. Thanks for the help, this is getting annoying

It cold be pcm but a pro will have to install it to program security to the truck otherwise it won't even start.
