I did some searching,and before I replace the fuel pressure reg,I thought I would ask...the symptoms seem odd.

85'500sel us,takes about 3-4 seconds of cranking to start...Just started doing this after a long trip so did not happen gradually.I have good vacuum at idle and have fixed about 10 leaks..It is getting colder here,about 40 in the morning.Also runs perfect once started,no funny idle,no hesitation,no sputtering-which kinda rules out fuel filter/ignition for me.

Now the odd part...once started,you can shut it off and it will start repeatedly almost instantly..The longer you wait to start,the longer it takes.This leads me to believe maybe fuel is leaking down from the regulator/injectors.But that shouldn't make it hard to start in the mornings,Right?

It cranks normal speed,and runs like a top otherwise..Any direction on where to start would be helpful.I have already changed out the fuel accumulator/fuel filter/plugs/wires/cap/rotor...

The rear fuel pressure regulator does leak down pressure..But I doubt it would cause this problem.
\Thanks guys...
