I have a 1974 145 and I am trying to troubleshoot the fuel injection system. The Hayes manual I have describes a control unit under the passenger seat, which I don't have, and describes the injectors as having bayonet fittings holding them in place. The injectors I have are held in place by a plate that is shaped like an asymmetric figure eight. Is the Hayes manual for a D-Jetronic and I have a K-Jetronic ?

The problems, which seem to be fuel related, are that :
(1) Usually, when the engine is cold, there is a hesitation when accelerating from a stop that results in a combustion sort of pop noise and then stalling unless I press down on the gas pedal.
(2) Sometimes, when re-starting a warm engine, the engine starts readily and then stalls immediately. Re-starting enough times results in normal operation.

I removed the injectors. One of them was wet. Does that indicate a problem with that injector ?

The connections on the control pressure regulator seem OK. Is this a device that is likely to fail in this way ?

Thank you for any advice.
