1990 tracker

yes i do.
if all coil is correct for your 89/90 sidekick and tracker.?

the tech reason for overheat, is dwell is too long or infinite, burning up the coil..
the ignitor is bad. in the Dizzy. or the pickup...bad, ill bet ignitor... as its a oneshot logic , i think, it may overheat and stick burning up the the coil..
these ignitors are infamous for heat soak issues too.
when you stop a car, the coil must be dead, or it overheats. (i have a points car that does that by design, Hitlers revenge, now has CDI system.)

see the drawing here. for the paths.

as you can see the coil has full 12v power key on, so only the ignitor, can burn it up.
all coils (most) have a max dwell time. or they overheat.
This tactic allows max high voltage. from the coil, Ampere/ turns. The ECU charges the coil to saturation, no extra. when working correctly.

Hi again thanks for all the help. I talked with the mechanic at the dealership. He said that the computer is sending out codes all the time even with the key off. I also replaced the coil, the fuel pressure regulator, and the O2 sensor and it again runs but according to the mechanic the computer is sending out codes all the time again any help would be appreciated
