Starting Problems

I don't understand what you are saying, Does the car have a relay that needs replacing or it doesn't have one and needs one. If the latter is the case what is the relay control mechanism?

It's quite common for starter solenoids to not energise if there is some resistance in the circuit.

Adding a relay makes the solenoid current path direct from the battery to the solenoid.

The ignition switch and neutral start switch form the low current path to activate the relay.
