That depends on where you bought the vehicle and what production run
it was. 93 had several computers. Your fairly much stuck with that
year as they made quite a few changes in 94/95.

Go here, enter your vehicle info, then
go down Electrical/Powertrain control/Ecm

The part number is on a paper tag on the front of the ecu.
Kinda hard to see and sometimes it does fall off. I think
the part number is also engraved in the ecu case.

hey man i got codes

12 Direct battery input to PCM was disconnected within the last 50
Key-on cycles
54 No camshaft signal detected during engine cranking.
55 Completion of fault code display on Check Engine lamp.

Do you think that the cam shaft sensor could be the problem being as it
is not detected during cranking.

Thanks
Dan

Yes, that is a problem. My son's van was recently dead with a code 54.
It needed a new pickup inside the distributor. I would try cleaning
it's electrical connection first though.
