Hello, my name is***** will assist you.
The only time that the scanner would not see the engine is if the EMM is not powering up. Make sure that the key switch is functioning correctly, and the main relay on the engine is closing providing power to the EMM, If they are both good, you will need to send the EMM off for repair.
Bad grounds on the engine will and can many things to not function as they should. Hopefully your new cable will do the trick.
Tapping into the harness could cause you an issue if there is not a clean, water tight connection.
Inspect the harness really well to make sure that there is no other broken or corroded ground wires.
i would recommend a compression test on the engine as well. Before spending that kind of money on it. Make sure that the block still has some life in it. These early Ficht engines had a history of failing to them.
That is actually sort of low. But it could have been the gauge as well.
I shoot for a minimum of 90 PSI.
