These are all the things I have tried:

1. No Injector pulse when ignition is turned on
2. Inertia Switch
3. Wiring injector harness
4. Power Resistors
5. CTS
6. TPS
7. ECU
8. Injectors

I don't know what's wrong. Could the 1983 XJ6 have the coaxial cable? If so where is it located? I've exhausted all my options.

 

The injector pulse originates in distributor pickup, then goes through ignition amplifier to negative terminal on coil. Check coil, ign. amp, pickup and wiring in between

The EFI system relies on a pulse from the ignition system. There is a wire, (I forget the colour), which goes from the coil negative terminal back to the ECU in the trunk. Basically, no ignition pulse = no injector action, the powered-up fuel system just sits there waiting for these pulses. Simple.

Good suggestions so far.

Also check the bundle of ground wires at the rear of the water rail The entire FI system grounds there

Hi Ransho

Did you ever solve your problem??

I am in a similar situation and have not figured out the cause yet.

Thanks
