...My "check engine light" nis on, i had it diagnosed from speedmaster, here is the report, /Total codes 001/
12 Faulty RPM signal(no RPM, NE and crankshaft position signal transmitted to ECU after started for 2 seconds)
1.CKP and CMP sensors short or open
2.distributor fault
3. start circuit open or short
4. module fault/

If you have any input about this, it'll really help...

thanks and merry xmas...

connect te1 & e1 on the diagnostic socket through a wire jumper, then switch on the ignition
but don't start the engine.

in your case, code 1-2 possible fault in your distributor circuit. could be a loose distributor socket.
