If kill switch is OK, pull the spark plugs and look for metal flakes (bad news).

If none, you need four things for it to run.

Spark, suck, Gas, blow.

Start by checking the gas lines from one end to the other. Then check for spark on the cylinders, then intake, then exhaust.

that's over heat sensor.. has nothing ta do with ignition and/or fuses.. if "any" jacket and/or wire is melted tha motor has gotten way to hot!.. ya need ta check tha warning buzzer for operation.. does it still have oil injection operating?

usually under tha dash or close to tha control box.. it should be in a small "mesh sack" of sorts at tha control box end of tha harness.. with oil injection module intact and wired tha way is supposed ta be you should get a short series of self check "beeps" when key is turned on?

to check buzzer do this.. on tha starb side of motor at tha small term block where tha tan/blue wires are at you will see 1 goes to tha oilier module, one goes to that sensor on tha starb head and one goes into tha harness.. separate/disconnet tha one goin' to tha harness and "ground it" on tha block at tha screw holding tha plastic block to tha block.. this should set off tha buzzer.....

So if the oil injector runs out does it shut off injnition. I pulled some of the plugs last night too and they look new. No metal or anything
