take off msd

 

check the dizzy and ignitor, also check your grounds

 

Dont forget to check that ICM

 

I agree.. MSD is a hit and miss deal.

 

same thing happend to me check your fuel system....turned out it was my old fuel filter....fuel pressure was set at 50psi and the second i changed the filter, it went up to 60psi....maybe yours is new but just thrown you my 2 cents

ehhh, has an aeromotive fuel filter... going to swap msd boxes, then try bypassing, then we'll look to fuel.
