No Spark MS2 3.57 Datsun 280Z

[Nate280Z]

I have megasquirt 2 v3.57 QuadSpark, IGN6, 36-1 crank wheel, hall sensor. I'm not getting a spark, I had DIY autotune install the jumpers for the spark output. I'm using a relay board, outputs S1 S2 S3 go to the Quadspark. In test mode I don't get a spark, but when I turn the key off it sparks.

Ordinarily, S1 through S4 would be for stepper IAC outputs. Please check your receipt to see what pins we installed the outputs on. They're usually set up so that DB37 pin 36 is spark A (that goes to S5 on the relay board) and the remaining ones are on the DB15.

I changed which outputs I was using. Now I'm using S5, DB15 pin 10 & 11 to the QuadSpark, to the coil. Still no spark. The coil has 12.15 volts, QuadSpark is grounded to the battery post.

Can you get a spark in output test mode?

[Nate280Z]

I don't get a spark cranking or in test mode. I was thinking about sending my ECU, QuadSpark and coil to have it tested. I swear my wiring is right.

PM me your receipt number and I can check how exactly it was modified and what pins it should be using.

Matt helped figure this out. I was using the wrong spark outputs. Also, my ECU is setup for direct coil control. I was using the QuadSpark ignition module. I used the correct spark outputs, removed the QuadSpark, and I got a spark!! Thanks Matt.
