Default extended cranking to start

No codes, new plugs CTS, MAS, coil. Sometimes must crank engine over several seconds to start. Fuel pressure 50. Once running, great performance.

The symptoms you described mostly fit those of a problem in the fuel delivery system, like a dying fuel pump, clogged fuel filter, and/or a bad fuel pump relay.

Look on ebay for fuel pump as there is one dealer that seems to be selling them much less than others (not sure if it is old stock) but their price is under $300 vs around $500 other places.

Can also get just the pump, just found, but this forum is great, thanks.

Since starting is hard it might be the check valve rather than the pump. Check out this thread.
