This came about after a mistake i made and shorted a power wire it damaged the starter relay i changed that and now I'm lost as what to do next Help!!
In the states we don't have that vehicle so I can't come up with a wiring diagram. Old car like that probably has a distributor, with some kind of crank sensor in it. That is where I would start looking. Check your inputs to the ECU & work from there. If you could post a wiring diagram, we could give you some more specific help.
You need to test if the injectors are being controlled. It is normal with key on engine off to have voltage on both sides of the injector. Disconnect an injector and with the test light connected to ground and key on engine of identify which of the two terminals in the connector is the 12v power, it is the other terminal the "control" we want to test. Now connect the test light to battery + 12v and connect to the control side of the injector plug. Now when you crank the engine the test light should blink.
