hey mustang people i have recently got a 89 fox lx with a micro squirt and turbo set up. when i got the car it barely ran and found it was just dumping fuel due to 70 pound injectors. i down sized the injectors to 42 pounds and it would run a bit better. i started the auto tune process on tunerstudios and now the car wont start at all, seems its not getting spark or fuel. i had put a base tune i found online on to see if that helped but it has not. i tried to see if it would fire with starting fluid and it did not. it crankks ok. also when it was running you could not rev the car up the second you touched the gas pedal it died instantly. i figured its due to timing issues but cant start teh car to check the timing. can anyone guide me in the right direction?

Verify that its getting spark at the coil. Unplug the idle air control valve snd see if it starts with just a little pedal.
