Not sure on this one but something cutting off fuel

[shiloh51933]

I'd:
1. Jump the fuel relay (use proper jump wire, spade type ends and insert into 15 and 87 sockets).
2. Listen to fuel rail with screwdriver + ear (ear to the end of screwdriver).
If you hear fuel running, all it means is that there is fuel flow, but the pressure can only be checked with proper fuel gauge.

How many miles in your 2000 Wagon, I have the feeling your fuel pump is going South...

I have a FP gauge, there was 0 FP at rail when fuel pump is cut off. When I jump the fuel pump it works and the fuel pressure is within spec and holds pressure. The L/F actuator wasn't working properly, probably just coincidental but none the less I replaced them. Anyway I have a clicking noise at fuse block above dead pedal when she doesn't want to start, is there another fuel pump relay in these cars? I replaced the FP relay at fuse block under hood cowl.
Yes I was thinking fuel pump was on way out because it dies out after an hour or two of driving. Again though when it dies out after driving for a long while I have a clicking sound under dash and when it's running there's a faint buzzing behind dash.

That buzzing and clicking under the dash could be a relay, i think

Loosen the torque tube bolt to body at front of diff. Mark the viscous coupler to diff flange. Remove the bolts and then remove the 4 holding torque tube (diff extension housing) and set the whole thing aside.
Take off the RH traiIing arm that goes forward along with the bracket to body.
Drop the rear muffler down and wire it to support it.
Support tank with floor jack and take off the straps that hold it up. Lower it a bit and disconnect fuel lines on RH sender.
Drop tank further so the RH sender is accessible. Unscrew the sender/pump cap and change the sender pump unit.

Your thinking it's the sending unit?

I was responding to the conversation within this thread about fuel pump change on that car model. I do think your fuel pump is fried based on experience but I wouldn't replace it without some verification. Fuel pressure testing while verifying 12v supply to pump is how I do it.

Fortunately there's access panels for the FP/sending unit in the cargo area when you remove the third row seating and fold down the second row seats
