You can try to access mil codes, see if it will work? You turn key till the dash lites come on, no further. Cycle the key on--off, on--off, on, then the mil on the dash starts flashing. You count the flashes to get the codes. Your looking for two digit codes.

How long since a tune-up? Did you check for primary voltage at the coil?
