164E ignition
 

A contact has erratic ignition, it only firing on half of the injectors. A replacement 'brain' was fitted but no change. He now thinks the triggering points at the lower end of the distributor, but I wouldn't have thought the car would only fire on three if the problem was them.
Another suggestion was a relay on the inner wing under the bonnet, but what it needs is an expert to advise: I am not one. Can anybody who knows please respond, as the car is currently immobile.
The loan of a complete functioning distributor would eliminate that entire unit if there is one in South Wales! This problem-car's owner will be eternally grateful.

Have a read of this thread. It is for B20E so 4 cylinders instead of 6 but the fault might be the same. Rubbing block wear.

If the B20E fires in pairs the B30E may fire in threes. The B20 dizzy has 2 sets of points against the B30 having to have three sets of points if the B30 had to fire in pairs. I've not looked at the parts book but I think they both have 2 sets of points. You'll have to check.

I have just got my 1970 145 with B20a running( after 20yrs dormancy), my dizzy has ONE set of points.

In addition to normal ignition points the F.I models have extra points in the lower body of the distributor to trigger the fuel injectors.

As a former bosch fuel injection technican (a lifetime ago in the mid 80's k-jetronic was my favourite)

I know how a little knowlage can totally screw up your injection system by mis diagnosis and improper adjustment.

Read about the injectior trigger contacts operation in the link above

I recomend the Dr-Djet bloke hes got great infomation

I have also been in touch with Martin who owns the 164e.

I think Martin said he has no signal to three of his injectors. (As such it's a fueling issue rather than ignition). I am certainly no expert on d-jet, but from reading the above links posted above, it seems that wear in the fuel injection points inside the distributor normally causes over-fuelling - due to the injectors staying open too long. I.e. the opposite of Martin's symptoms.

I don't rule out some other fault inside the distributor, and it's certainly worth trying a good one. Another possibility is a break in the wiring to injectors. I have suggested Martin checks continuity.

Any other suggestions welcome
