No start, rich if forced to start 200 1990

I have a 240 with LH 2.4 that refuses to start. This is what I have found:
The engine can be started with starter fluid when cold, but will idle high even after it has reached normal operating temp. Diagnostics on terminal 2 gave a 1-2-3 code, replaced the ECT. Car was brought in when it was about 50f, but temp has dropped to 38f during days, i.e. car would start when it was dropped off and now it will not. Probed terminal 2 on ignition control unit to terminal 13 on the ECU (ECT circuit) and got 5400 ohms which is OK for 38f. Removed cold start injector and found it was leaking. Replaced injector. Removed hose from fuel pressure regulator and there is no fuel leaking past the diaphragm. Did a fuel pressure test and got 43 psi at idle, 90 psi dead-head.

Currently: Cold start injector will not fire when engine is turned over, but if I ground one of the terminals on it it will spray and does not leak after ground is removed.

If I clean the plugs and start it, it has a high idle and will foul the plugs out. Any ideas? Any help would be greatly appreciated.
