You never mentioned if you have spark at the plugs or not. Engine needs FUEL/AIR and SPARK to run. Connect voltmeter to battery terminal on distributor and other lead to ground. Turn ignition on and see if you have battery voltage. If there is voltage hold one spark plug lead with insulated pliers and the bare terminal close to engine block and crank engine to see if there is spark.If spark occurs then it is not the distributor.If spark does not occur then check distributor ignition module, pick up coil, and pole piece. If there is no voltage to distributor then check out the battery lead coming to distributor which should be a pink wire.

 

today I checked the spark again: there is, but it is rather orange, than blue, looks very weak.

I checked the ground, it is good at the frame and the engine. At the pink wire and at the distributor/coil i have - as long as the ignition key is at the off position - somewhat over 13 Volts, but as soon as I turn the key, it falls down to 0.120 and goes up to 0.600 Volts as soon as the starter turns.

Could a broken ignition key lock cause all before mentioned and also this problem?


thank U for all answers

 

hi all

could a damage in the distributor itself cause only orange spark lights?

 

The voltage should be zero if the ignition is off. Key on and engine not running you should have 12-14 volts.....If you have voltage when switch is off then I would say the switch is bad.

 

dear friends

thank you for all your help and instructions .

my poor car suffered from multiple problems :

- the ignition module (I tried out three of them) were faulty, bought another new one, additionally the pickup coil was burnt and and the magnet on top was broken, so they had to be replaced, too

- at last, the garage, that installed the starter motor constructed a short-circuit by letting the + cable from the battery to touch the exhaust pipe when driving, problem didn't occure while standing

so finally, the car got back on the road again, I still have to fine-tune the distribution, this was the first time I was setting this up by miself without an diagnostig light, but at least it is running again.

thank you for all very, very appreciated help from all, I learnt a lot during the recent few weeks.

good times and rides for all
