Urgent assistance needed for no starter, no start condition.

I took a running drivetrain and complete harness from a 93 Miata and moved it to a different tub(95 Miata).

The car now has a no starter, no start condition.

We removed all the airbag endpoints. I don't think that would cause the car to show no starter, no start condition.
We looked for open grounds and grounded them.

The battery is charged, and the starter will turn over arc'ing the solenoid/starter.

What could be the issue in the harness?
Missing a ground, something not connected?
Looked over it several times, but no joy.

Urgently need assistance to get this motor and harness to run, need to get the car running for the Lemons race this weekend.
Any help is appreciated. The car is at the Dallas Maker Space in Carrollton. It's an incredible place, you have to see it to believe it.

We are heading back to work on the car Friday at 8am and staying until this thing runs. The race is Saturday morning!

PM me with your contact number if you can assist.

Starter interlock switch on the clutch?

Put a test light in the S wire, ground the other end and turn key. Light should be seen.

Did you use the keyed ignition switch from the 93?

Did you swap the ecu as well?

I'd also suggest chasing down the clutch switch and see if it has current when closed. After that, I'd consider adding a stand-alone wire and see if it will run. You can always have an old-school momentary switch button to get it fired.

Isn't there another clutch safety switch wired in to the tranny? I think it can be bypassed by jumping it.

We took the 93 motor, harness, and pcm and put it into the 95 tub with 95 steering column, key, and pedals.

The 93 harness clipped right into the clutch pedal switch on the 95 tub.

Will check the clutch safety switch, there are a couple of connectors on the manual tranny. Will check that those are connected into the harness.

Need more clarity on what the "S" wire is, and location.

^I think 'S' is for starter.

There were 2 switches on the clutch. Added the second connector and now we have starter.

and a fuel leak :)

Well you can nail that down with a lighter...

S is the signal wire going to the starter solenoid from keyed ignition. This wire should have 12v when the key is turned to the start position. If the test light glows when the key is turned you can skip checking the clutch switch.

I see you got it. Just answering the question.

aww I asked on facebook a few weeks back if y'all wanted help with this car and nobody ever answered me :(

Sucks your race seems to keep getting snowed out.

So after the we got the starter working and the fuel leak shored up. Still couldn't start the car.

It would bust off with brake cleaner, but not on it's own fuel.

Found out the fuel lines were connected backwards, we were fueling to the back side of the pressure regulator.
Flipped those around and the car was up and running.

Replaced the clutch master and slave, but it would not bleed down.
After 50-60 pedals, we put on the vacuum bleeder and got it to bleed.
I suppose I should have primed the parts before installing.

I don't face b..., so I'll miss all those communications.

Sounds like it's about ready for a race! Glad to hear it was just little stuff. Post up a pic when you get a chance!
