Sorry i posted in the general section by mistake as i'm new to using this forum.

Hi. I've got the wasted spark conversion from msd. I got them to fit the driver to my super 8 ecu running 8 injectors but i haven't had the car running properly since. I sent it back to them to get checked and when i got it back it only ran on cylinders 2 and 4 a few times but won't start at all now. I've fitted a new amp as i thought it could be that but made no difference. I took the spark plugs out and they all spark initially when i turn the ignition on but when i turn the engine over only cylinders 2 and 4 spark. Any help would be appreciated as i'm tearing my hair out lol

Thanks
