New developement, HOPEFULLY ITS FIXED>> FINGERS CROSSED>

Yesterday, we completed the crankshaft sensors replacement, and plunked in a new crankshaft oil seal while its apart.

We took it for a test run and it shut off while driving again after 20 minutes. This time it wouldn't restart.

Had it towed to the shop.

Today they ran the diagnostics, ecu pcm and sensors all ok. Still wouldn't start.

Fuel pump was erratic. Fluctuating pressure. So they repaced the fuel pump. $800 later, I drove the car for about an hour now, and it runs great.

I'm hoping the problem is solved.
