1995 7.3 has no power

Hi I have a 95 7.3 powerstroke. As far as I know all that the engine has is ad injectors out of a 99 and a ts chip. When I bought the truck I took a huge shot in the dark because it all of asunden it stoped working while me and the previous owner were talking. I brought the truck home and found out the fuel jelled so I dropped the tanks and cleanded them and put new diesel in. After all that I changed the fuel filter to be safe. Now thw truck starts again with absolutely no power so I replaced the injector harness and pigtails because the drivers side was bad and the wiring was shabby on both sides but I still have no power. It has no power to the four injectors on the drivers side and I dont know if this is because the fuel pressure is low (22psi) which brings me to my question what is causing all of this. I'm thinking it is a bad fuel pressure regulator.

You arent getting a signal to 4 injectors? if so thats PCM or IDM

As far as low fuel pressure it could be the fuel pressure regulator but they rarely go bad. Id suspect the pump but you can rebuild or at least clean the fuel pressure regulator screens

there will be a brass nut. its an 18 or 19mm I cant remember. inside there is a small spring and a shuttle. Those are what puts pressure on the regulator spring itself. A lot of guys put a BB inside the shuttle to stiffen the pressure on the spring. That may be worth a try but dont let your fuel pressure go over 70psi

Ok well the truck is running now but the previous owner must have beat the piss out of it because I was cruising around town in the truck to see if anything would act up and I snapped the yolk
