I have an Emergency SOS Magic Start Ignition Unit that will work on any vehicle with a distributor cap and rotor. It has 2 leads that clip onto the battery and a single HT lead that simply replaces the distributor HT lead. It will get your car running and bypasses any ignition or electronic fault. It was actually designed for points and carburettor vehicles, but my 3.9 V8i ran on it even after I removed the power to the electronic distributor. The unit was banned about 35 years ago as it took 15 seconds to steal a carburetted car…I managed to get hold of this unit for emergency get-home use, but fortunately never needed to use it.
