Sounds like the memory retention power wire for the ECM is dead.

what do you mean by this? and where is it located?

What it means is that the computer has to re-learn the engine every time you start it. I don't have my 89 book handy, but the 91 book has a solid yellow wire that runs off the battery side of the starter solenoid through a 20ga DK Blue fuse link that goes to the ECM power relay and then splices off directly to the ECM computer. Check for power at pin #1 of your computer with the ignition OFF.
