Over our summer, I finally go around to replacing the starter solenoid. When trying to start the car when hot, I'd get a "click" and that was it. Usually took a few tries to start. Traced this back to the starter solenoid. While I considered replacing the whole starter, I managed to find 2x NOS solenoids, Paris-Rhone part# CEDY-438, on Ebay. Since I have headers, it was easy enough to just remove the solenoid and replace with a new one. Even though it's the same part number, the DeLorean solenoid uses a bullet connector, but the NOS had a spade connector - easy enough to change over without touching the original harness.
Also, finally fitted a B28E Control Pressure Regulator, Bosch part# 0-438-140-038. I had a junkyard one from a Volvo, and exchanged my core with Colin at
https://k-jet.biz/ for a rebuilt unit. Interestingly this has a machined lower half, with an adjustment screw. Since Colin sets the pressures on a bench, I didn't touch the adjustment screw. He knows his K-jet stuff - highly recommended if you need a rebuilt fuel distributor or CPR.
As per
http://www.deloreaneurotec.uk/viewtopic.php?f=12&t=495, I've left the top port on the CPR open. A quick test drive with vacuum connected to the test port was very sluggish compared to leaving it open. From my research, the -038 CPR has lower cold and warm control pressures.
One day I'll get it on a dyno...
