You might test the thermostatic actuator. I replaced mine with a manual one and if it is left in the wrong position (warm engine setting), my car won't start when the engine is cold.

I replaced mine with a manual one and if it is left in the wrong position (warm engine setting), my car won't start when the engine is cold.My Alfa lost power and cannot be re-started. The electric fuel pump is humming normally, the fuel pressure light comes on and goes out almost immediately. There does not appear to be fuel on the plugs or air intake throats after cranking a few times.
I read some earlier posts about the fuel cut off solenoid and microswitch mounted on/in the Spica pump. How can I diagnose these, and fix if there is a problem? Is there any other part of the fuel system that could cause this type of problem?
Thanks for any info you can provide!
I hate to state the obvious, but have you checked that the drive belt for the Spica Injection Pump is intact?My Alfa lost power and cannot be re-started.

Don't know if they are still available but mine was offered by Shankle many years ago. For what it's worth, I'm thinking of going back to a thermostatic actuator at some point. I know they are expensive but I'm always a bit concerned that there is some slop in the Sure-start cable that makes the manual adjustment imprecise.Thanks green 69 gtv and JoeCab! The 72 GTV is running again, after changing the main fuel filter, checking the timing belt (it was OK), and inspecting the thermostatic actuator. I also cleaned out the distributor cap and rotor, which looked good to me. I'm not sure what did the trick, which worries me a bit. Anyway, it's good to be running. BTW, where can I find the manually operated thermostatic actuator?
