(i dunno im not too sure about how a cars wire sistem is activated.) but i know for a fact the ecu provide a constant 12 volts and then when to start its supose to ground itself to start the ignition process. or sumthing f that sort.
Well man its the ECT, which is the coolant temp sensor. Its doesnt control the ground, its a variable resistor which changes with temp=Thermistor. All that does is change resistance values based on temp causing a voltage drop on the return side. The only thing i can tell u for now is to look and see which circuit that realy goes to, it might not even be an issue, relays do weird **** sometimes when a component is failing. if you give me your email ill try to send you some diagrams off of mitchell or alldata when i get a chance. goodluck. Its real hard to help u out not bein there man, but il try
Theres a lot of thing you can check ign. wise. You said the coil has power at it, follow that down to the next spot where you can check such as the dis. Hook a screw driver on the wire and ground it while someone is cranking it and look for spark. Its a giant process of eleimination. try your best and dont give up. If you are getting power to the coil that far up htere is not that much of the secondary ign. system that can be checked. Like he said also did u check the crank sensor
