[abscate]

I think I have a spare know now go back s good one for sale, but I got a freebie paid forward to me. If your in a garden of green nest I can send for a test . If money is tight , paying it forward is right

PM and let’s check part numbers.

I’ve got a used one from ebay that’s supposed to arrive tomorrow. I appreciate the offer though, there’s some good people on this forum.

Let us know if you find them.

Bad part or the cam belt has slipped out if time.

Is it much of a pain to check the timing? I’m familiar with how it works but I’ve never had this car apart.

JUst put good White out on the marks and turn the engine over slowly to see if the lineup

Best done with spark plugs out

I’ll give it a go tomorrow, I’m hoping I find something wrong so I can quit chasing my tail.

Checked timing today, it’s spot on. Thankfully the dealership who last did the timing belt made super obvious marks.

That leaves a potential electrical issue assuming both parts are good.
