Hey folks. New here and any advice or redirection is appreciated. I have a '03 V6 that I got 4 days ago. Ran great until yesterday then died. Engine will turn over but will not run. I hear the fuel pump prime but there is no pressure at the schoder valve. Had a buddy crank it while I was under the tank and could hear the pump for a sec or two after he stopped.
Thought it might be PATS. Disconnected the transceiver and the "THEFT" light sped up so I tossed that. Power going to inertia switch (which I reset just to see) and power going to pump (hence the noise). Any ideas on what next?
Sorry if this was taken care of in another thread. Been searching the last few days... Any help is appreciated

Change out the fuel filter.

That's what I thought at first as well, but that would mean it went from flowing to 100% clog. Later on I am going to disconnect at the filter and see how much flow I get.

How much flow got clogged at once isn't really the issue, the issue is troubleshooting the system. The only serviceable part between the pump and rail is the fuel filter, and at $14 for the Motorcraft part (I think it's like $7 for a brand X) it is the least expensive fix too. Make sure you have the spring clip tool to disconnect the fuel line and then the hardest part is jacking it up and placing the axle stands.

I can appreciate that logic. Trouble shooting 101! Picked up all the stuff on the way home from work and will change it in the morning. Thanks for your responses!

Fuel filter was a no go. There is no fuel coming from the pump. I hear it come on and prime, but it almost sounds like it's dumping the fuel back into the tank. Any ideas?

Done. Apparently the person that installed the last fuel pump didn't secure the fuel line to the pump, and it came loose. Dropped the tank, hooked it back up, zip tied it and she fired right up.
