740 turbo power/fuel issue

[travis873o]

So, here's where i'm at:

-I've replaced the intank pump/sock filter. Verfied that it is working.
-Replaced fuel filter
-checked the fuel pressure regulator and it is in working order.
-I can hear my main pump running.

Symptoms:
No power past half throttle almost like a fuel cut but i'm only pushing 9lbs max.
I only have no power after the vehicle is warmed up and is even worse on hot days.

Any thoughts? I'm pretty sure this is a fuel issue but could it be a vaccum issue?

Thanks

Hi Travis,

Have you tried any of this:

Your '90' 740T diagnostic codes may help rule some things out. Does the problem occur at a certain RPM every time? See what kind of codes you get and post your findings.

My check engine light does not come on though. Could I still have a code but no light? The light does work, it comes on for the gauge light test when i start the car
