well i havent driven it in a while and so i had to push start it since the battery was dead, then i drive it up to work, i goto drive home and the motor is tapping loud and sound like the timing was off, so i pull in and check it out and timing is good but one of the lifters wasnt working. so i figured id drive it home and fix the lifters, i get in start it up and backup and it dies and havent got it to fire up since, ill replace the ecu and see what happens. if its a 95 with a 91 6 bolt would it be better to get a 91 gst ecu or would the harness be different....
