    HELP! No start after injector install

    Swapped out to 17# injectors and it won't start! Everything is plugged in and tight. Fuel lines are in and tight. Injector harness is plugged in and is clean, no corrosion.

    Ran before I started and it cranks really strong but nothing. I have spark and fuel. I understand I just let all the pressure out of the fuel system when I swapped injectors but I have been attempting to start and cranking for a while and nothing.

    I can get it to fire with starting fluid but I am not a fan of that because no one wants an ether baby engine.

    How long should it take to start back up? Any suggestions. I did find a few other posts but most if them didn't follow up after the problem was fixed.

    It have 45 psi at the fuel rail and I checked the injector harness with a noid light and I was getting power to the injectors.

    I tried the m20 section but no response and I am I desperate need of a solution. It ran before the swap, I am confused!

    How long did you try cranking it for? When I depressurize the system, I usually need to crank for a solid 5-10 seconds.

    Which 17# injectors did you put in there (Bosch PN 0 280 ### ###)? Could you have made an oops and stuck in low impedance ones?

      They are p/n 0 280 150 415. I bought them rebuilt from a forum member. Crank multiple times for 15-30 seconds

      Anyone else?!

        I refreshed the stock injectors and put them back in this morning and the car fired right up! I am happy it's running but bummed the 17# injector didn't work.

        O well I guess. I wonder what made them go bad?

          I ohms tested all the injectors and they check out good. I tried to check to see if they are stuck buy using the 9v battery meathod and they are all stuck closed!

          I guess when you get rebuilt injectors you should install them right away! I had them for a few months before the install and I guess that made them stick

          Anyone have any any tips on how to get them unstuck? I am trying to avoid paying for an entire new set of injectors but that may me my only option right now.
