Question about Hyundai Motor 1992 Scoupe
I just rebuilt my daughters 93 Hyundai scoupe, i did nothing to the electrics except unplugged them an back in again. I checked the coil an 12v was present but when cranking over it went backwards in voltage to 9v. I wasn't sure about this so i grabbed another coil and it did the same thing. Is this normal? if it is i'm not getting a spark as i pulled a plug out and put near motor and got absolutley nothing. I have triple checked all electrical connections and im getting very frustrated. Is it a sensor? Is it a computer problem? Please please someone help

Sorry to tell you this if you dont already know its the ecu, take it out take off the cover and youll see the main capacitor in the center (its a black capacitor with grey markings, there are a couple of others similar located around the board but this one pretty much in the center) of the board has black suit around it and on the board, if your carefull a $3 capacitor (your local **** smith electronics will have one) and solder it in making sure you get the polarities right. unfortunately with these model cars it is a major problem, but if you are not confident with the work email me at matmenzies.adam.com.au and i can referr you to an ecu recon joint for around 85 they will fix your ecu, NOW the problem, there will be a reason why the ecu blew, it will be simple like cracked lead or wire earthing somewhere on chasis, you see the smallest earth spike, even from say turning the car over too much will blow that capacitor. sorry for the bad news and i hope i have been of some assistance.

There won't be any spark for the plugs with this problem. The camshaft position sensor is what tells the PCM to send spark. There is a circuit malfunction with this sensor. As the name implies, it will be near the camshaft on bank 1. Mounted to the head. This has 3 wires and is held in place by two bolts. You will probably need to pull some things out of the way, air snorkel, engine cover (if you have one).
