Unlike my 164 with the fuel rail running the length of the 6 cylinders, twice, the 5 cyl engines only have a foot of line going across the intake side of the engine. Not quite hot enough for vapor lock.

Holding pressure at the pump is too costly and difficult and not needed. The pump easily exceeds 43psi in less than 1 second so that required pressure for the injectors is always there.

But, if the fuel drains back to the tank, the 2 second prime during key posII time is not enough to send fuel to the rail and build pressure.

If the car won't start right away, try turning the key to posII a few times and listen to the pump do its thing. If it then starts, the fuel is probably returning to the tank.

If it still has a hard time starting, have you checked the spark plugs lately?

BTW, the sun made its appearance, first time in 7 days!!
