Afternoon everyone,
Your thoughts would be appreciated before my Dad takes a chainsaw to his Chim !
Car is 430 Chim with Tornado chip ACT trumpets and has all been set up by Dan Taylor TVR.
After about 50miles car spluttered on motorway as if going to cut out but actually didn't.
On return to garage on drive failed to restart and had to be pushed in.
Following morning started up on ramps then died again and wouldn't restart.
Started next day again after we changed coil ( coincidence I think ) then ran in garage for 1 hour then cut out turning over and not starting.
Before its recommission and set up by Dan it has had airflow meter, stepper, cap rotor and leads...............
Could this be ignition amplifier or relays for pump or ECU ?
Any ideas would be much appreciated before its broken for parts......... !
Also how bad is the starter motor to change as again looks like an exhaust manifold removal !!
All the best

Could well be ignition amp as they tend to fail when hot and come back to life when cold.

Is the fuel pump running during these issues?

If the engine is cranking then the starter is unlikely the issue unless it is cranking slowly. Removal is done from below and does not require the exhaust manifold removing.

First move is to get into the classifieds and buy a Rovergauge lead and software then you can test the car and give us some more clues.

Where abouts are you? I have a bag of known spares I have lent to people to help them, including Rover gauge cable if required. If you use Dan Taylor, hopefully, you are not far from me in Bromley?

Basic checks first.

Earth points?

Spark?

Fuel?

What condition is the startermotor wiring in? - I'm doing my Wedge at the moment and the power cables need replacement.

Ign amp, but do try a different lead from coil to dist cap first as that will be the most likely lead to fail.
Check connections to fuel pump are clean and secure.

Many thanks all for all your replies really grateful
Car based in Greenwich will try your helpful suggestions first and let you know how we get on.
Ignition amp will be the first thing any reliable contacts to get one instead of the usual made in China rubbish ?
Regards

The starter motor is easy to access from underneath, one push on cable for the coil, one nut holding the power cables and two bolts holding the motor in place.
