i have a 96 convertible that had a 3.8. i installed a 95 3.8 engine tranny, cradle and all. it was all a plug and play. now i dont have fire to the plugs. all ran good on the donor mustang motor before the install fuel pump turns on and the motor turns over but to spark ........ any ideas ? Ive changed computers but still no spark

 

Key matches the computer. Did you swap that out as well when you changed the computer?

 

this 95 doesnt have a chip in the key, but i am planning on installing the cluster with the computer today. i did this swap on my 2000gt and it fired right up. i did change the cluster, steering colum,and computer though. the guy i got this donor car from said it ran fine he just needed the engine for another mustang.
