I did a search and didn't find anything.

Anyway, I was cruising in my FD and everything was normal. I pulled into a store and had my turbo timer on while I did some shopping and noticed that my fuel pressure gauge was extremely high when I returned to my FD. I drove back home and it was still high, even when I was barely on the gas. I let the car sit for a few days and drove it today and it's still the same.

My inj duty from the PFC is normal and the fuel pressure increases while I'm accelerating, which is a good thing. My idle is normal and the car feels fine.

My mods:
Upgraded fuel pump, which I had for about 5 years and never had a problem.
Upgraded Injectors, which have been upgraded 2 years ago and never had a problem.

Any idea what could be the problem???

 

I lost my aftermarket fuel pressure regulator recently. The symptoms were that the fuel pressure did not change with manifold pressure. Does your pressure change if you remove the manifold pressure line ftom the regulator at idle?

I have to try it out tomorrow to see if there is any change.

Thanks
