FordMasterTech :

im guessing your wanting the fuel pressure specification and not the reading right

FordMasterTech :

spec is 35-65 psi

FordMasterTech :

so you are in spec

FordMasterTech :

is that reading you took while trying to crank the engine?

FordMasterTech :

??\

Customer :

I don't know what the fuel pressure should be for the cars system. I have put a fuel pressure gauge on it (car not running) an got a reading of 45 PSI. The engine will try to start and if I keep trying it will start then stop after a few seconds.

FordMasterTech :

what is the fuel pressure reading while you are cranking on the engine

Customer :

It is the same.

FordMasterTech :

ok thats good pressure your problem is not there

FordMasterTech :

you do have spark correct

Customer :

Yes I do.

FordMasterTech :

ok do you have a voltmeter

Customer :

Yes

FordMasterTech :

remove the throttle position sensor connector and check between the vref to sig ret wire

FordMasterTech :

top and bottom pins

FordMasterTech :

key on engine off whats your reading

Customer :

I replaced the sensor about 6 months ago. One thing I didn't say is when the car died after getting it started I checked

Customer :

the spark plugs and they were dry.

FordMasterTech :

yeah but what is the reading im not checking for something else

FordMasterTech :

im checking for another problem not a problem with the sensor

FordMasterTech :

if you go through this test with me i can guarantee we will find this problem and fix it

FordMasterTech :

if you dont want to i can opt out and you can try your luck with someone who will guess for you

Customer :

Right now I don't have the car in front of me. But if you can explain what I need to do, or I can contact you when the car is in front of me.

FordMasterTech :

ok i see when can you have the car in front of you?

FordMasterTech :

the

Customer :

I will be able to check it around 4:00 pm (Pacific Time) or what works for you (some time next week).

FordMasterTech :

the first thing i would do is check those two wires with your voltmeter on dc volts key on engine off if you have between 4-6volts thats good then i would hook up a noid light to the injector and while cranking see what the light does and then if it has coil on plugs which it should i would hook the noid light to a coil plug and see what it does while cranking
