Ok speed sensor-critical for starting. Once the car is running you can even unplug it. The car will stay running.
Reference sensor needed for both. If it was bad car would shut off. No O2 sensor? Are you sure? TPS. FPR. Water temp sensor. |

That's really interesting to know.
 If he's somewhere other than in US or Japan, there will be no O2 sensor. It is a tacked on system for those emissions plagued markets.

yes i do not have o2 sensor (i am in Europe) ...today was working on the car ..i have put together the interior (leader dash -seats with alcantara/leader ...leader door panels ...leader console ..and alcantara steering wheel
 ) ...after that i was working under the bonnet and saw that the reference sensor plug was melt (all the wiring connecting to each other )  so now is the question: all the wiring from the sensors are going directly to DME? reference sensor goes directly to DME? AFM goes directly to DME? water temp goes to DME? injectors goes to DME? all the engine sensors goes to DME? i am asking because wiring "thing" i do not get very well from the diagram. and i will like to connect new wiring to all the sensor if they go directly to dme (if not please someone tell me for each one the rout )

Yes, they all run straight to the DME. Here's the pinout for the DME. Some things, like the TPS and AFM have numbers on the contacts that actually correspond to the DME pin numbers they lead to. Very convenient.
DME Connector 35-pin

ok guys i solved my problem...
it seems that my afm was bad...the dme it wasn't reading afm signal because of bad wiper (witch was making connection with ground ) and because of that dme was running always in open loop...from there that feeling of unburnt fuel ,lack of power ,big fuel consumption... it seems that i somehow missed this problem when i was testing afm before . now...my ass is jumping how huge difference is when i push the acceleration pedal (yes this is the first time when my engine is properly working-i was dealing with this problem since i got the car )thank you guys for all your help
