Mercedes 450SL: d-jetronic issues : Enige does not run on all 8 cilinders

update:

The last week of August I have made an appointment with my garage.
They will check that there is no interference between gas and petrol.
So that answer has to wait.

During the revision of the cylinder heads the wiring was measured for breaks. Everything was OK.
But in the mean time there is so much tinkering with the 40 year old wiring that we will do so again.

Oh yeah I completely forgot to mention. Because of fuel leakage at the pump some time ago
we replaced all fuel lines and we measured the fuel pressure at 2.1 bar. So that's good too.

The mechanic who did the work on my car could not say which injectors did not pulse.
But he told me that all injectors received pulse and that the problem did not occur always on the same injectors.
So that did not help to pin-point the problem.

I suspect that the garage does not know how to proceed anymore and just saying replace this or replace that,
and that costs rise without a solution.

I'm going to print and follow the D-Jetronic checklist.

Hi Hans,

sounds like a plan
