Truck wont start please help!!!

[Nightmarearcade]

we bought an 03 Silverado for $3,000 with a catch, it wouldnt run properly. when we drove it home, the rev limiter was displaying that it was runnig about 6500 rpm when it wasnt. it would only shift to second and once in a while it would shift back to first and it felt like someone just rammed into use from the rear. After having it home for a few days we replaced the gauge cluster and that fixed the issues with the tranny not shifting right. But even then to start the truck we struggled. we would have to keep cranking it for a long time. It would turn on my doing this 1 out of like 4 times the rest we would have to use ether to start it. We got tired of it not turning on and after 3 time of it leaving me stranded we decided to have it checked by a gm tech. and he told us that two of the injectors where bad. my dad being cheap he had it fixed in mexico with people he knows but it only worked for a few days and it started doing it again. the injectors they used died out too since they where from a junk yard. So we finally got some refurbished injectors online with a year warranty. we finally got to putting them on. But now our problem is that it wont bleed properly and because of that it wont start. if we put ether it start but then dies out. Is there some speciall way of bleeding it that we dont know? we have tried priming it while having the bleeder valve pushed in( the one front left of the motor that looks like an ac valve) Any help would be appreciated. Thanks

The bleeder screw is next to the primer it is plastic.

thanks for the help but we already tried that too with no result.

The primer is for the filter. The CP3 is going to do the lines. Do you have a fuel leak somewhere? You shouldn't need to push that valve on the engine. It is for testing. I don't think eather is the best for our engines. People have done some major damage with that stuff.

we got the truck to run now but after driving it around for a bit when i got home an turned it of it would start again. we had to prime the fuel filter again. and when it ran it would only run for about 45 seconds and then it would turn off. i think it might be the fuel filter assembly. It might be getting some air from some where. What do you guys think

try changing the fuel filter. i kinda had the same problem. i started my truck up one day and it ran for about 45 sec and then shut off and didnt start back up. but when i just changed the filter, it started right up.

Were you able to get the truck concerns resolved this weekend, Nightmarearcade?
