    tells me the vss sensor has 3 wires one going to the ecu one coming from a junction spliced to the main relay and then going to the under dash fuse box,fuse 12, and one ground coming out of the sensor. i dont have the sensor plugged it or attached in anyway.

    alot of manufacturers assign the fuel supply management and ignition managment to the ecm which gets its informations from the sensors located inside the distributer providing the information to the computer to manage the fuel supply and ignition. bad sensors in the dizzy no fuel, or no signal from the dizzy to the computer no fuel.

    thank you, clarified alot. so its not working because there's no signal, due to wire cut, bad connection, interferance etc correct?

    good news! or maybe bad? so i was unpluggin my fuse like u said to see maybe if it did sumthin and as i was turning the key over a couple times to try the jumper i noticed my fuel pump wasnt turning on anymore and my relay was no longer activating. so i figure i cut a power wire from the feul relay to give power to my fan relay. and if i remeber correctly the relay also gives power to the ECU? could that be the reason for a solid cel code? i only had enough tiem to figure that out for now. on saturday i will verify the problem with my no longer working relay.

    I fixed my relay, bad power wire. then proceeded to hook up my fan and my ECT, fixed my IAT. errased my codes and all i have left to do is the VTEC oil pressure switch, which i haevtn hooked up yet. So i turned over my engine and.........I GOT SPARK!! Thanks blanco ECT was causin no spark, needed its input. now the car wont start but im assumin from messin with the dizzy so much and jumpin the wires ireally set off the timing. so im going to redo the ignition timing, drain the coolant and oil, replace, and try to get the bad boy started. on a side note i need new lower control arms, preferrably reinforced. i have found rear ones but no front. if any of u no where i can get some please let me no.
