03 lb7 cut out and wont start - Page 2

Ok, my only deal is there's an issue with the security system, it is hard wired to the fuse Bo by a switch to bypass it.. Will flash the security light and once in a while it will turn off and seem like it shuts the truck off quick then back on... I need to figure that out, also have an edge programmer that I would like to take out anyone have a wiring diagram for it? I may have an issue with the filter head and electrical . Also engine code was for 2 injectors

i replaced injectors on an 02 for a guy and i had a delivery tube(high pressure line) leaking which caused it to not even start.... obviously thats not your problem but it goes to show how finiky these fuel systems are.. one little leak will cause it to do some weird shit
