Starting Problems Options

I drove my 1974 1.8 briefly after sitting for two months in the winter. It drove fine for the mile or so. I went to drive it the next day and didn't get too far before it chugged, jerked and then died. Had it towed back to my house. Inspected all the vacuum hoses, electrical connections and cleaned the air flow sensor and plug. Starts for a few seconds at times and then dies. Other times it won't even start. Had new plugs, points and fuel filter installed about 10 months ago. I can hear the hum of the fuel pump, so I don't think it's that. Mechanic can't see it for two weeks and I would like to get it running. I would appreciate hearing from the 914 community about similar issues. Thanks.

try wiggling the EFI harness in the engine bay.
particularly the plug to the AFM. but also wiggle generally along its length.

check for spark.
though it sounds like you are getting that if it fires as you say for a few seconds.

sounds like you have fuel delivery given fuel in the injector rail.
but this does not mean your injectors are firing.

what you describe fits symptomsl for an ARM plug that is not properly seated into the AFM and has come loose. (also check and clean the plug into the ECU at other end). i know you say you have done checking and cleaning but additionally try manipulating the wires where they enter the AFM plug.

the other thing this symptom fits is the engine firing off the cold start injector but the main injectors not firing. this will allow the engine to start and run briefly. 5 seconds or so.

i guess the other thing this could be is the dual relay has given up the ghost.
kind of fits the bill too as its run one day and its all over the next.
