Oh CRAP!

When I got off work and went out to start the Z it was taking a real long time for the engine to start. When it did it was running very rough. It settled down while I was plugging in my GPS and I proceeded on. As soon as I got on the Interstate I could tell that something was wrong as my AFR was pegged at 18! The car was bucking and not happy. I pulled over and looked a my fuel pressure gauge (under the hood) and it was only reading about 40 psi when it should be in the mid 50's. As I was limping the car home it kept getting worse. When I finally got home the fuel pressure had dropped to less than 20!

The pump runs when the car is turned on and then shuts off as if it has reached it's pressure cut off however the pressure gauge is still only showing 20 psi.

I'm pretty sure that the pump should run continuously and excess flow is returned inside of the pump. At least that was what I remembered it doing when it was working correctly. Does anyone know if the pump is supposed to run continuously?

Anyway the trip to Z1 is off until I can fix the problem. Robert at Z1 was very understanding and wished me luck. I had pre-paid for two nights stay that I'll lose too. Double CRAP!

I'm open to ideas. I hate the thought of taking the pump out. I have full tank of gas and that will need to be drained of at least three gallons so it doesn't spill out. It is 105 degrees now. I wonder if the temperature sensor has anything to do with this problem.

CRAP, CRAP, CRAP!
