Hi,

There is no such device on these cars, that is a Ford feature. What is your issue?

Expert:  Doug replied 9 months ago.

Thanks.

Can you confirm if you have spark while cranking? Either by pulling a plug wire and plug, grounding it and cranking, or by spraying starting fluid in the intake and cranking to see if it kicks at all.

Took the hose off the fuel pressure regulator cranked it didnt see any fuel sep out
Expert:  Doug replied 9 months ago.

Great.

Don't worry about the regulator side hose, it won't normally be flowing too much fuel, so it doesn't really signify anything certain in either direction.
Lets loosen the two 10mm bolts holding the pressure line onto the fuel rail, then direct the pressure line into a receptacle and have a helper crank the engine... does the fuel come out like a firehose, like a sink faucet, or of course not at all?

Just a side ? Is the fuel pump supposed to make like a hum or something when you turn key to accessoriea
Expert:  Doug replied 9 months ago.

No it is not. The fuel pump only runs when the crank sensor is showing engine RPM. This is a safety function to prevent the pump from over-running in an accident etc where it might be spilling fuel. No engine RPM, no fuel pump operation.

Ok. We are about to do the throttle body test u asked me about
Expert:  Doug replied 9 months ago.

Spraying into it with starting fluid?

The purpose of that was to verify if you have spark primarily... which you said you already know you do. However it will also give an indication of internal health of the engine (if it has compression), so it is still worth doing.
