How long should the fuelrail hold pressure after engine is shut off? What is the normal operating psi for this engine?
(Serial #OW657850)

Thanks Much
 
I`ll guess around 40 psi. should not fall off at all. leaking injectors will let if fall off quickly

It does carry 40-45 psi throughout all operating ranges, it does fall off pretty rapidly when engine is shut off...
#4 spark plug smells of gasoline when I took them out...
Any suggestions on where to purchase new injectors?

Thanks again
