    the fpr on the new rail might not be good.

    if you got fuel it should at least try to start. if the vac line off it has gas in it, or smells of gas the fpr is bad.

    what are these new injectors? stock replacements?

    check for spark yet?

    side note, the injector harness can have a bad spot that you aggravated by taking the plugs off. so you can look for a break, or also test the power at the plug, test light works, or you can take a marker light out the head light and push it in the injector plug. you turn the key to run and the bulb should flash a few times, or the test light will flash if its got power. it only flashes a few times then you have to re cycle the key, its the prime for the engine to start. if it dont flash at all you got no power to them.

    That maybe it because it wants to start but won't I checked the vac line it was dry but it does really smell of gas after a few cranks so I'm guessing bad fpr? They are stock replacements and another question how do I get the fpr off all the vids on YouTube are for the N/A and not supercharged don't know if its different being on the opposite side of the rail

    Connect the big plug in front if you left it unhooked.

    If you step on the gas while starting with a bad FPR sometimes it will start.
