Help! 1995 mustang gt does not turn on after installing throttle body and CAI. When key is turned to the ON position, the check engine light does not come on. I have heard it could be a failed PCM. How could a PCM fail while/after this type of install?!? Instead… Could this be associated with the mass air flow sensor or TFI since I was touching and working with these connections. Could these prevent the car from starting?

I have rechecked all connections dozens of times. Fuel is at 3/4, battery is at 85%, and throttle body has been tested before installing CAI.

Any help is appreciated. Thanks.

Cranks but no start situation?
Have you tried starting fluid?

I have tried starter fluid. I after I tried I realized the CEL isn’t coming on when the key is in the on position. I think it’s the TFI. I’m going to replace that. Fingers crossed. But one note the TFI in my car looks different that what LMR sells. Hmmm maybe it’s just original old one vs. new one.
