Combilift C4000:
No Spark - won’t start

Hi everyone!! I have a C4000 Combilift s/n 4045 - with the GM 4 cylinder (cast iron head) that has no spark!! I have replaced the ignition coil and the ignition module to no avail. I have voltage at both the distributor & the coil. The rotor is turning when cranking, the leads test ok, cap & rotor look ok. This particular coil has two plugs that push in together to form a 4 pin plug. Negative side seems to test ok as does the 12v side. I'm wondering if maybe I have a distributor fault?

Hi Mr Pitt. Great advice from Skyreach and Scott re the wires to from the distributor and to not only test for continuity but also ohm as there is a diode in one of these that may have failed. You might need to replace one of these.

I haven't worked on many combe lifts but I might be able to help you first are you not getting spark to coil l would check the pick up coil inside the distributor there will be two wires ohm them out they should ohm between 500 and 900 ohms also give a light pull on them if they break that is your problem also undo them to ohm from module. If you need to change the distributor must be removed to install. hope l was of help.
