Also check to see if your getting spark. Pull the primary off the distributor
and have someone hold it close to the block while the engine is cranked. Just
keep the primary closer to the block than your hands or your gonna get one
hell of a shock. I generally stick a sparkplug in the boot and ground it with
a jumper wire.
Not sure of the 88, but in later computers if the car doesn't get a crank
sensor signal in a couple of revs it cuts power to the coil.
That and all the fuses.
The other thing is to check the coil for any melty spots and the rotor for
a burnthrough. Sometimes the rotor burns through right were it sits over
the distributor shaft. Real pain in the *** to diagnose.
Oh Yea.. and one other thing.. run a heavy jumper cable between the
engine block and the frame. If you have a rotten engine ground strap
it will never start.
