Help needed with DIYPNP setup
 

Hi. I've got a European 10AE and have the ollowing mods:
- Reverant-built enhanced DIYPNP
- COP conversion kit from TSE
- GM IAT sensor and MAP sensor (in the DIYPNP)

At the moment, it cranks and smells of fuel - that's it :(

Tomorrow I'll install an LC-1 and play around with some more settings but I'll appreciate it if anyone wants to have a look at the map and log of the cranking.

Any help is appreciated.

So, back at it today.

A few extra bits of info:

We got spark and fuel at all cylinders.

According to TunerStudio, it cranks at around 185 rpm but it sounds like it always did when it started fine. However, the tacho in the car isn't moving at all. Does this sound like anything that would prevent a start?

Any help would really be appreciated.

Not an MS expert here, but if you have spark and fuel at all cylinders, but it won't light, then you have a timing problem. Put a timing light on it while cranking and see what's going on. On a new setup you have to sync up the MS with the sensors.

Weird though that it would be *that* far out since the 99 doesn't have any adjustment in the sensors.

Thanks. Even though it smelled heavily of fuel, it turns out to be a fuel problem after all. The fuel pump relay didn't switch on - currently working on it :)

If Reverant built it I have a hard time to believe that the fuel pump outlet is on the wrong pin (EU 99 with Immo have it on a different pin than the US).
My build thread might give some hints https://www.miataturbo.net/megasquirt-18/99-diypnp-1-5-build-comments-questions-48516/

IIRC if you have no Immo the fuel pump outlet is on the same pin as the US without Immo (the pin in the DIYPNP build manual).
