Question type: Maintenance & Repair

I have a 8 month of 1995 3.8 automatic mustang engine went in it replaced it with a 3 month of 1996 3.8 mustang engine ,engine worked great with no problems but when I put it in my 1995 im not getting any spark to any of my plugs and I have a check engine light on in my dash it just cranks but will not start my 1995 has been sitting for a while before I put the 1996 engine in it do you think it could be a bad ground or something easy ?

Um, actually no. The 1995 model is OBD I, the 1996 model is OBD II. Completely different onboard computer systems. You'll have to transfer the PCM (computer), wiring, and probably the sensors, all of them, to get the '96 engine to run in a '95 car. Sorry! -Jim


what I just did a 1998 3.8 mustang swap in a 1994 3.8 mustang and all I had to change was my moter mounts ran great then I sold it and bought this one lol


Was it a complete engine or did you transfer parts from one engine to the other? It'll work that way. -Jim


just a compleat 1996 engine hauled it out and put It in every thing pluged in the same and every thing but just cranks wont start .my old 1994 I did the same procedure hauled a 1998 3.8 mustang engine out and put it directly in the 1994 I had to change my moter mounts tho hooked every thing up and took right off after a couple cranks worked good but my 1995 on the other hand lol I am officaly stumped I have no idea


thank u for ur reply t is hard to get a answer from other sites lol


I am stumped too. The 1996 models were the first year for OBD II. Earlier models were OBD I. Sorry I couldn't help but good luck and please let us know what it was when you get it fired up. Thanks, -Jim


yes I will thank u for ur time


found out wat it was it was the crank sensor wire it was broke off lol
