- Coil resistance sounds close. Make sure you measure it + to -with all wires disconnected.
- Coil voltages sound suspicious.....
- Ballast sounds like it is upside down....needs some checking. Remove all of the wires to it and recheck resistances. The post with the single brown wire coming off of it should be the on half that has the much lower resistance. 5 ohms is normal for one half; 2 ohms is a bit high for the other but may be tolerable for now.
- makes sure a brown wire goes to + and a black or black-yellow wire goes to -
- turn the key to run without starting and measure the + and - voltages
- if - is still higher than +, then something is probably wrong in the wiring to from the key to the ballast and coil +
- Spark sound good (which is a GOOD sign but not consistent with all of the above data).
- And compression numbers are VERY good and consistent. Being a bit different one side the the other is not of any huge consequence; small head, deck, or head gasket variations will make those 5 psi differences. Were these numbers taken with a bit of oil added into the cylinders or 'dry'?
- Sounds like the idle circuit is not doing ANYTHING. Try restarting with the 5 pumps, and when it fires, keep pumping it rapidly and see if it will stay going.
- What is the room temperature there?
