Citroen DS23 ie

Hello and thank you for adding me to the list

My name is Warren and I live in Gold Coast, Australia. Cars include a Citroen DS23ie and Citroen SM 3.0l carby

I have an unusual problem with the DS. It has all the original D Jet injection. Only change is a 123 distributor with electronic triggers for the injection

When cold (say 24-26 degrees C here) it will start and run fine all day long. However if it is switched off and left, say, 5 minutes it will crank but not start. Leave it to cool down +/- 3 hours and it starts and runs fine again

I have checked fuel pressure, spark etc and replaced the coil, HT leads, spark plugs, fuel filter. Adjusted valves. Injectors were replaced 2 years ago

I have tried swapping out the ECU and pressure sensor but no difference. Also no difference if I disconnect the cold start injector and thermos time switch. Disconnecting the wires to the thermal sensor TS2 causes the engine to run very rich

My local Bosch Euro service centre has not been able to help at this stage

If any of the experts have suggestions on possible causes of the problem, I would be very appreciative

Thank you

Warren

Hi Warren,

welcome from down under !

I propose that you do not mix introduction and problem solving. So please open another thread with your problem in forum D-Jetronic and please also describe there how spark and spark plugs look like when engine does not start.

Apologies for the breach of forum etiquette
Thanks again for including me in your group, and I will re-post regarding the engine problem
