Cannot find the correct year manual (any ideas) which would help a lot with trouble shooting.
I can get a code "21" which says ignition signal missing at ECU/CPU.
Replaced ignition switch, coil, and resistor/capacitor, no luck.
Could it be the crank angle sensor? Is there an easy way to test?
BTW I signed up for a "chiltondiy.com" site and purchased the specific 1987 D21 online manual, what a scam! Generic info, no specific stuff. Be aware.
Thanks for any advice you can offer.
