Gauges removed, DZ keyless, won't fire up?

[MidnightRider]

So here is the current state of my '78 280Z:

Gauges are all removed

DZ push button start is installed

Fuel pump runs

Plugs have spark

Engine cranks... but that's all it does. My car won't start.

 

I'd appreciate any suggestions, I'm really scratching my head.

I believe, you need the tachometer to be hooked up.

We bridged the leads so that's not the problem.

That most likely is the problem. The '78 doesn't use a current triggered tach, like the '70 to '73 does, so you shouldn't need or want to bridge anything at the tach connector.

Problem solved: Computer wasn't powered up. I didn't realize the computer had a separate plug for power. You don't need the tach to be installed to start the car. I went ahead and tested that to disclose the myth.

There is no myth. The tach must be hooked up, or shorted, in order for a 240Z to start (current-triggered tach), but not a 260Z or 280Z (voltage triggered).
