Having issues with my 89 GT not starting. I did a wire tuck and installed a single turbo at the same time. Alot of parts were changed, and i went back and rechecked everything. Upon first startup, It cranks ok but won't fire. Bypassed my aftermarket ignition and picked up an hei spark testor and i'm getting spark. Also picked up a noid light and getting injector pulses as well. Fuel pump primes and have 40 psi at the rail, so now i'm totally stumped.
