Main Relay Clicking Rapidly No Start

[YEPEE]

should be a number on the relay 25230-????? if those are the same relays have you tried switching them around? I dont recall green relays but I will check mine, usually the issue is a blue relay with 2 plugs on that side, but a Canadian vehicle might be different.. can you post pics???

Picked up some new relays installed it, nothing. Added a ground strap from the battery to the head to see if that helps, nothing. Replaced the coils and getting power to them but no spark out of them. And still getting the rapid clicking at the relays.

You can take the relays out and bypass them.

There is a little diagram drawn on them to show you how power should flow. Grab yourself some heavy wire, like 14 gauge home wiring, and shunt the connection long enough to test out that the relay isn't causing the issue.

At this point I'm guessing the starter, if the battery is good. Hard to say without being there to observe.

The starter cranks just fine. Will turn over just won't start

Going to try bypassing of the main relay if that does anything.

Rather than that tried to pull codes from the ECU under the passenger seat but the lights are just flashing like a Christmas tree. Can't get it to read codes properly not sure if this helps with my issue.

Oh! I was under the impression it won't crank.



No spark at the plugs? Could are good?



Does the Z24 have a sensor for "crank angle" like the VG30's wave plate?



Take a video of your blinky lights and link is to youtube.

LOL - that's what they do.

Did you see the video in my signature?

This is how an ECU with the twist-dial switch works:



This is how an ECU with the toggle switch works:

That tiny little detail, at the start , would have helped a lot.

Correct no spark, coils are good checked with my other truck are they are fine. And the coils are getting power to them with the key on. (getting 12.3 volts)

Relays keep clicking like crazy so I'm not sure what happening.

And will try to pull codes again today.

Usually, relays click when there isn't enough voltage to keep the switches open.

Can you find a piece of cable to go directly from your known good battery to the relay's power wire? Sometimes the wiring gets corroded inside the wire insulation. Not often, but ti happens.
