88 GL Wagon cranks but won't start. Replaced coil and getting good 12volt hot to + side but still will not produce spark and will not start. Cranks up a storm but no start. Suspecting ECM but not sure.
Before you change ECM, You must make sure you have spark from plugs..If not pull the distributer it tends to shatter internally which the eye cannot tell unless opened properly.
I had the exact problem and it turned out ther is a power module by the coil and it is a small round gizmo on a mount right by thre coil and it makes it seem like the brain and spark wont get to the distributor so we bypassed it by splicing into the hotwire that goes int the distributor by using the headlight hot lead and you should getspark now

Thanks. I pulled the cap and everything seems to be fine inside. rotor seems to be pressed on a little tite and will not "pull" off but seems to be good. Getting power to the new coil but no spark from the coil to the distributor.
what is the fuel pressure?
no power out of ecm (under airbox) to ign coil
