When I am cranking I have fuel pressure but once the car turns on and I turn the key to the on position I have no fuel pressure and the car turns off.

I have searched the old post and they say that the car is in safe mode. Which means the AFM is screwed up or I have a gigantic vac leak.

What does it mean if when you jump the yellow plug and the car stays on? I know it is supposed to mean the AFM is bad but what if you checked it with the manual and the resistance is fine?

I have checked the resistance on the AFM, Circuit Opening relay, and the Fuel Pump Resistor Relay and they are all fine.

The only way the car will stay on is if I turn it on and then open the AFM flap manually with a screw driver. I have checked for vacuum leaks and I can't find any.

NOTES:

The day before the car was running perfect. This morning I changed the alternator pulley and then tried turning it on and that is when it started happening.

I did the fuel pump rewire about a year ago and it has never given me a problem.

I have the Rtek chip on the computer.

 

In the AFM there is a little switch that allows current to flow to the fuel pump when air is flowing through the AFM otherwise it could flood. Your switch is crook!!!!! By shorting that connector you bypass the AFM switch.

But what if you checked the resistance on the AFM with the FSM and it is fine? Can it still be messed up?

 

Alright, I jumped the yellow plug and tried to start it and it is still doing the same thing. It turns on for about three seconds and then turns off.

My fuel pressure gauge is not moving. It doesn't move when I am cranking or when the car turns on for the 3 seconds.

I can stick a screw driving in the AFM it will stay on a little bit longer but the gauge still reads zero.

 

are you sure that the TID is connected to the turbo really good?

my car did this once, and I had just knocked the TID off the intake on the turbo.

 

It is connected pretty good. I checked the fuel pump to make sure it was throwing out gas by taking one of the hoses off and it is shotting out gas but my fuel pressure gauge is still reading zero.

 

Do you guys think it might have something to do with the pulsation damper. It has a small little screw and it came off so I went ahead and tighten it?

 

Regarding the zero fuel pressure...

If you have flow, you should have at least a little pressure. Are you sure the guage works? The pulsation damper shouldn't be a player, but the pressure regulator obviously would be. Have you tried clamping the fuel return line to restrict it, and then checking the pressure?

 

I am going to try that.

I was planning on taking the line that goes to the FPR off to see if gas is reaching it.

 

you might want to look into replacing the pulsation dampner anyways, especially since you mentioned the screw coming out and you tightening it back in...

and yes regarding the fuel pressure, it's pretty hard to get ZERO pressure if you have SOME flow.
check out everything in your fuel delivery system and make sure that gauge is working...
