'91 ecu troubles
#20

this and injector drivers are the 2 most common failures of ALL ECU.
in 1996 they didnt have overload detecting transistors like today.
end story, bad ECU.

the oBD 2 scan tool should show P03xx codes, for lost of spark.

That is what I have been suspecting all along. Correct me if I am wrong but slow blow fuses could have helped in protecting the transistors.
