I have been working on a hard/impossible to start issue with my 92 JDM FD in the last couple weeks. Since I wanted to do some maintenance and look over the whole car anyways I didnt worry about fixing the issue until after that work was done.

So i put in a new fuel pump, fuel filter, redid the rats next, new plugs, new wires, etc....

That work has been completed now and Im troubleshooting the hard/impossible to start problem. I tried to check the codes last night but all I am getting is a solid MIL. By that I mean when i turn the ignition to the on position it illuminates the LED for a few seconds, then the led goes out for a few seconds then comes on and stays on. I think this means I have an issue with the ECU but have not been able to find any documentation to support this. Anyone know what a solid MIL means?
