TVR chimaera non starter. No spark from the distributor.
Discussion
Hi.
Apologies for another 'non starting' thread.
Appriciate any help.
Thank you.
Spark from the coil high tension lead to distributor.
But no spark from the distributor to spark plug.
The car had not been driven for about three weeks.
Took it out on a local shop run, after the third short distance stop.
The car would not start.
I moved the ECU and loom away from the battery, to
Jump start the car with jump leads, from another battery.
Car started.
Drove it about four miles home.
Left the engine running.
After about two minutes. it stopped.
Tried starting again. would not start.
Checked fuel to engine, thats ok.
Checked spark to plug, no spark.
But there is a spark from the coil H/T lead to the distributor .
Battery as been charged was 12.3v, now about 12.8v-13v.
New coil fitted.
New ignition amp fitted.
New distributor cap fitted.
The rotor arm is very tight to come off. so not changed that yet. (it does look ok,)
The place where i brought the parts from, tested the coil, ign amp and distributor.
They said they all worked, but a bit low in power from the coil.
Thank you for any help and info.

Almost 100% its the rotor arm leaking spark to earth.
To test the rotor arm.....
Remove the cap and tie it to oneside.
Remove the king lead from the cap.
Using insulated pliers and thick rubber gloves hold the end of the king lead close to the centre of the rotor arm. Or better still use clamps so you dont jave tohold it.
Turn engine over as if starting the car.
If spark jumps across the gap to the arm it is defective.
