I do have a scanner, at first it threw the theft system code, so I erased it and it didnt come back. All theft lights are working normal.
I also dont see the point of buying a pressure tester if there is no pressure to test yet. Obviously will when it starts holding pressure.
I just tested the power going to the injectors, which were all good and the same. Tested the ground side with a test light going from battery positive, and no lights on any of them so they arent grounding open. Im in the process of getting a noid light next.
I really hope it is something easy I may have overlooked, cuz this is killin me.

--Yes I am going to go get one, even though it doesnt hold pressure, I can test how much it makes with the pump running at least.

Not having enough or having too much fuel pressure can both cause issues, just pressing the Schroeder valve and spraying fuel everywhere doesn't tell you anything other than there is fuel present. It also creates a fire hazard

--its only held the pressure once, when I pulled the whole rail out, zip-tied the injectors to it, and cycled the pump to check for leaks, which there werent any, and suddenly it was holding pressure. I put everything back together and tried to start it, it fired for a second, died, and back to not holding pressure in the rail.

What specific code was it? Many of the folks here can be a ton more helpful when you're specific with your details, just saying "theft system code" doesn't help much if there were 30 different codes related to the theft system.

--the theft code number I cant remember, but it was from trying to start it for too long. After it doesnt start for a certain time, the theft system activates.

Everyone here wants to help each other out.

--I appreciate it and thank you.

If I were having your issue, before I started worrying about the injectors I'd start with the parts before it, since your pump runs does it create the correct amount of fuel pressure because that is actually important for the injectors to operate correctly.
A thought occurred to me, since there also needs to be spark present, have you checked that the coils are firing?

--yes, getting spark, and have replaced all the plugs. When I pulled the old ones they were wet.

Thanks for the replies, and all the help. Its rough learning all these things about fuel injection, and not having a vehicle to go get the parts.

I think Pat may have been thinking of the engine side of the fuel lines? You did mention you had that end apart too.

I caught the remarks inside the qoute

Maybe your pressure test will lead to a solution.

Here's a link to a troubleshooting page I just found on testing fuel pressure

http://troubleshootmyvehicle.com/for...he-fuel-pump-1

I read a little bit of it, and it has some good info in there.

The ones going to the rail looked much larger, so I just left them on. So they should be good, and like I said, it held pressure when I picked it up and trued to look for leaky injectors, plugged em back in and all the hoses, and held still. Only when I tried to start it did it go back to nothing. Then every time after, no matter if i unplug the injectors or not, the rail will not hold pressure. Ive tried cycling the key on 20 times, and still wont.

So I am going to test the pressure with the pump running,(will get my 5 year old niece over here, she likes turning the key, lol) because if I cycle the key, its gone before I can run from the drivers door to the front of the truck. I dont see what good its gonna do, but the more data points the better I spose.


Also yes thanks for the thread, I feel as tho I have read them all by now. But yes thats one I used when I started this venture. Do you guys mind if I start over again and ask advice as I go? It seems much better than waiting till I get super frustrated and asking questions like I did in the beginning of my fuel extravaganza I got goin on here.
