Coolant temp sensor wouldn't kill the motor.
I'd verify that your fuel lines are correct. The relays you should check are the three on the firewall. They're for the O2 heater, the fuel pump and the main power. Do you get a check engine light? If that lights while you're turning the car on, the DME is getting power.
I'd suspect the DME is being wonky & not priming the fuel system. Typically that's from the crank sensor not sending a clean signal. Is the gap on the sensor OK? Resistance readings in spec? 680 ohms IIRC.
It'd be pretty obvious, a small hole punched in the thermo flange outside the main valve opening. The jiggle valve has a very small brass tube punched through the flange and crimped loosely around a small bearing. I don't think most thermo makers use on for the M42 (shame too, they make bleeding a bit easier), just mentioned it in case it did.


I got lucky and found you a "before" shot. If you draw a line (on your picture) from the yellow #2 to the yellow #1 you will see the opening of the hose that #2 connects too. Should be a plastic 90 there. #1 goes down to the Check valve on the Carbon Canister.

If it has a bleed hole or jiggle valve, that end is up. Otherwise it makes no difference.
