My Omni has run perfectly since installing the S60 wiring etc back in 1997.

It was nice out day today so I decided to go to the car wash and clean him up.

A few miles from home it bucked a couple of times and stalled out completely.

I hitched a ride back home and grabbed a fuel pressure tester and a spare HEP.

Once back at the car I attached the FP gauge, gave it a try and it fired right up.

Fuel pressure was fine so I started back home and the same thing happened again.

Must be the HEP, so I swapped it out, fired right up and once more I headed home.

Back home I decided to run it down my road a bit and it started acting up again.

This time my eyes were glued to the tach as a falling tach was always my HEP test.

I kept it at 4 K RPM, the tach needle was steady but it bucked again and stalled out.

Almost home, I had to use my old quad to push it inside the shop.

This time I checked codes and got a code 43, never saw that one before??

I researched 43 as best as I could, it seems to be ignition or SMEC related.

The wiring is in excellent condition and the grounds are all in place.

I'm still working with only 1/2 a brain and one hand after my stroke.

So now I'm kindly looking for any advice on tracking down this issue.

Questions:


1: I've never had a SMEC go bad, has anyone else had one go bad like this??

2: I've never had a coil go bad, has anyone had one go bad like this?

(It's the 1990+ style that mounts with the thermostat housing.)

3: One lead should have 12 v, the other flash with the Engine cranking, right?

4: If the coil lead flashes does that eliminate the HEP and SMEC?

Thanks
Randy
