Crank wont start

are the injectors firing ? Is one of them stuck open ? Is that the normal fuel pressure ? Purge the fuel rail when it won't start and try again , don't start any fires . Let us know what happens .

How do you check if the injectors are firing? Not sure on the pressure. The internet said around that pressure. How do you purge the fuel rail. I did push the Schrader valve and emptied the rail before test. To late started a small fire. But no damage to wires. Just back of insulation behind of manifold. Starter fluid did it.

I got these codes also off of the dash, after turning the key 3 times. P0508, P0113, and P 0123

there's a couple of web sites that list the codes , you'll have to do the leg work and get there definitions , if it started after emptying fuel rail it could have been a bad regulator , as far as injectors they make a noid light , but what I did ,(now don't tell anyone) is got an old stethescope from a nurse and if you put it on the injector you can hear it "piddle " away .

Thank you. I looked up the codes. Guess I will have to dig deeper. After I installed the new fuel pump, the truck Ran great for a day. There was some popping coming from bed area. Hard to tell exactly where driving down the road. Wondering if that has something to do with it. It ram great before the fuel pump went out. I'm pulling my hair out trying to figure this out.
