Hello there I have a 1977 datsun b210 hatchback with a manual tranny. Recently, I have problems with starting the car. The motor turns but the car won't start. I checked if it has some spark but no spark on plugs, checked the distributor cap to see if there was a problem with it but nothing the distributor cap was brand new, checked the spark plugs and saw that there were some plugs with some oil on them I believe they were on cylinders 3/4. I dont know how to check for voltage on the rotor on the distributor or on the coil. Can anyone Help me please...
