Are there any ZX2 guys here, or Ford Mechanics?
I'm trying to figure out one thing. Does a 1999, or any year ZX2 have a fuel pressure regulator? I can't see anything on the rail. There is in fact, a fuel pressure sensor. It seems that the regulator exists, because Ford was more than happy to sell me one. I know this car inside and out, have even had the engine out once, but even though I hold this $100 phantom part in my hand, it does not seem to be attached to the engine, anywhere. My Ford DVD rom manual mentions nothing about this part being on the car either, only the fuel pressure sensor.
Does anyone have any idea?
Thanks!

If the fuel system doesn't have a return line (only one fuel line to the rail) then it uses a pressure sensor and the ECM pulses the pump to maintain pressure. (Pulse Width Modulation)

I'm thinking my long cranking problem may be a check valve in the fuel pump. Unless the pressure sensor can cause this, even though it does not appear to be leaking.

After talking to several people and many phone calls, I found out that there is no fuel pressure regulator on these vehicles. And yes, there is no return line, only the line going to the rail.

Try cycling the key On for 2-3 seconds, then Off, then to Start, to prime the fuel system before cranking. It should start easily then if the check valve is bad.

I suppose the only fix for the check valve is to replace the fuel pump. So the question is, do I spend the $495 and get one from the dealer that I know will fit and hopefully last another 220,000 miles, or get the parts store one for half the price that is probably made in China and will probably crap out on my in two months like the power door lock actuator they sold me did?
