So I just did my s14 black top swap on my s14. The car will crank but won't spark. Not sure why.

Already checked...

Igniters (3 different)
Ecu. (Factory and Jim wolf)
Camangle sensor
Checked all grounds

If anyone has any idea feel free to message me.
Thanks in advance.

the harness, you changed the parts but forgot to look at the harness itself.

did you mod the harness to get WS premade harness.

It's a wiring specialties harness. Plug and play

Do you have all the grounds hooked up?

Yes. Checked all grounds. Still nothing.
Checked starter relay and fuses too.

Think it's the harness from WS! 🤦*♂️

Since WS builds harnesses in batches, and the pinouts are verified by plugging into a computer which lights up green or red, it is highly unlikely that the WS harness has a short or is pinned incorrectly. Give a call and press 2 for tech support or email [email protected] - we are very good at helping customers figure out what is wrong.

To confirm when you set your key to ACC, do you hear the fuel pump? If you dont, check the harness near the ECU (it attaches to the chassis; black/white plug similar to ECU plug) to see if that plug is locked in. I had the same symptoms and this was not plugged in all the way.

have you tested for spark on each cylinder? SR uses individual coil packs so all cylinders should be checked for spark individually
and have you tried jungle juice yet?
and is your ignition timing on point?
