Righto, so after clamping down all hoses and filling her up with fluids etc, I went to start the rb20det S13 for the first time as an RB.

No joy. :facepalm:

As soon as the battery is connected, the headlights, tail lights, indicator lights(on dash), heater controls all turn on. Doesn't matter if the switch is on 'off', 'accessory' or 'ignition'. (Its push button too btw). Got a 3 way switch for accessory, off & ignition with a push button to start.

At first it was cranking well and seemed very promising. After a few unsuccessful attempts, I went in for another go. It began cranking then it just stopped cranking while I was still holding the button in. :ohno: Hasn't cranked again since. Theres still power to the starter & fuses all seem ok.

Wiring definitely is not my forte and somebody has helped with (done most of) the wiring for me so Im not entirely sure on whats going on with that.

I'm new to the engine swaps (this is the first) but am keen as to learn. If anyone has any experience with similar issues or knows what and how to test then I'm all ears.

This is probably something fairly simple that I have completely overlooked. Sorry in advance if that is the case. Unfortunately there is only one way to learn.

At the moment though, I'm stumped. Any one wanna lend their handy 2 cents?

ECU? Bad Earth? Relay?


Cheers guys.

Please correct me if I'm wrong, but after some more thought I have come up with possible culprits..

Battery - tested (12.6v) also tried a friends battery that got them to my place minutes before. So it's not battery.

Wiring fault in the starting circuit

Ignition switch

Neutral safety switch

Starter solenoid

Starter motor

Bearing in mind that the car cranked well a few times and stopped doing so mid-crank. Can any of these possibilities be eliminated?

I will start testing these anyhow. Any pointers or ideas?
