Experience with these injectors
In cold temperatures (40F & Below) they intend to stick closed and the truck will not start. The primary cause is tar buildup on the injector nozzle. Sometime you can get lucky and remove the injector and clean the tip with choke and carb cleaner and it will solve the issue. A quick test for this is to use something soft like a screwdriver head and lightly tap the injector and occasionally it will come unstuck and the engine will start.
Another common problem is the o-ring on the nose of the injector gets torn or the o-ring goes missing and the engine will not start. Simply remove the injector and inspect the o-ring for damage and presence.
The most common problem with the injector is it has just gone bad and needs to be replaced. A good indicator of this is the 5A fuse on the injector harness is blown.
