I have a 350 with tuned port. New 22lb injectors, new harness and computer from larry's electric, chip with vats removed, brand new blaster 2 coil, msd 6al, and msd pro billet dist P/N 8366. My # 7 cylinder is dead on the drivers side rear. I have tried 3 spark plugs and they all come out wet with fuel. I am getting spark through the wires and the spark plug. I have a pretty large vacuum leak in between # 3 and # 5 cylinder where the cold start inject is. It is plugged but seems to be not good enough. Could this cause a dead cylinder? I know the map and 02 sensors are reading incorrectly with this leak. I had a carb on it and it ran great. thanks

 

anyone?

 

compression check?

 

great. ran good with carb new summit towing cam and heads where jst off and checked. new rings to.

 

maybe a defective wiring harness ?

 

Sorry, I got bit again assuming that just because its new its always good. I got a brand new msd dist. and the module was bad last week, got another one under warrenty its fine. So now the new injectors this week. One guy under any amount of pressure sprays, not leaks, sprays so found it. Thanks
