I've been trying a bunch of stuff, but I can't seem to figure this out.

A while back I pulled the motor to replace the oil pan, and also changed the timing belt, water pump, and all that at the same time. Ever since I put everything back in the car doesn't want to start. It cranks fine.

I checked the timing belt, and it seems to be fine:

I also opened the oil cap, and peaked inside, and the cams are moving.

I have no spark, I pulled the plug wire, put a sparkplug in the end, and attached it to the negative battery to ground to check for spark:



I also have no fuel, I pulled the plugs, and they are not wet, nor do I smell it.

However, the fuel pump works. I can hear it. I also know there is fuel pressure, I cracked a fitting barely open and saw it pressuring out.

The coil pack also seems to be fine.

I pulled out the harness, and traced all the wires, and checked them with a multimeter. The harness was fine.

I cleaned all the ground spots, and made sure all the grounds was good.

I changed the camshaft sensor with a brand new one, that did nothing.

I haven't changed the crank yet, however I repositioned it, just incase. I don't think there is anything wrong with the crank sensor, since I never messed with it before.

I have an Adaptronic ECU, and the ECU is working fine.

Anyone have any ideas on what could be causing this?

crank sensor is on wrong

I checked the sensor, it seems to be correct.

A member on miata.net suggested the crank trigger wheel needs to be flipped. I'm going to try that.

Shot in the dark try your Fuel pump relay

Dumb question not apparent in pics..

you DO have the crossover tube in place, right?

I had the same problem today... first check for spark if you are getting an initial spark but no more after it is your trigger plate... I just posted the correct orientation thread today for the plate.


Hope this helps,

Found the problem, had the boss hub backwards.
