Thanks in advance for reading! (Long)

I have an 89 3.0 V6 Montero LS with automatic transmission. It has gotten some issues of late that I can't seem to get my arms around.

1) Diagonostic (trouble codes). I have searched without success for an OBD1 port on this vehicle. According to Chilton Manual I should find it under the fuse panel. NOT (unless I am looking for some other type of port (non OBD1) that I dont recognize as the diagnostic port, I don't see any port there I would guess to be diagnostics).

2) My check engine light stays on constantly and does not flash. Most OBD1 vehicles I have owned in the past and present have a flashing light when a code is present. What is the likely cause of a "constant light"? On a Mitsubishi, does a constant light indicate a stored code?

3) Starter Issue. I have installed 2 rebuilt starter solenoids and a rebuild starter with solenoid (that would be 3 solenoids) total. I'm still getting an intermitent failure of the starter drive gear to engage the fly wheel. It just 'clicks'. If I turn the key enough times (i.e. click it several times) it will eventually catch. What could this be other than the solenoid? My battery was replaced this Spring and shows 12 plus volts when engine is off. There is no indication that I have insufficient voltage to the starter. I have not attempted to meassure cranking amps under load, as I'm not familiar with that test, but should I check that? Would a weak battery (interms of cranking amps) cause this issue.? I can have Schuck's Auto check this for me if needed.

4) Cold Start Issue. When I first crank it over in the morning (48 - 60 degrees ambient air temperature), if issue 3 is resolved and the engine cranks, it tries to start but sputters. The next try it runs a bit longer and then dies. After several progressively longer sputtering idle runs it will finally keep running and then smooth out. No problems the rest of the day with initial start once it cranks (ref. Issue 3).

Any help or suggestions will be greatly appreciated!
