Spark issues

[tcr 13 2 Cars]

Help needed with my pug .. got no / intermittent or very week spark while cranking but as soon as you stop cranking there’s a strong spark . Trouble I’ve got is it’s running a dta ecu with ford coil pack ( which has been replaced) along with all earth / battery cables etc https://youtu.be/We6UVTPHKXccables

Is this a new installation that has never run or a running car that has broken down?

 

If it's a new installation check that the ignition switched live you have used is one that stays live during cranking, some of them are cut off to assist starting.

 

If it's a runner that's broken down and you've ruled the obvious stuff out it could be a faulty starter motor, I've had a couple that crank fine but interfere with the engine management.
