Fuel fuse ? There's a distribution box under your close to the battery I'd imagine..
Open the cover the relay your looking for SHOULD be marked inside the cover..
Sometimes the write what it is and where on the diagram sometimes it has numbers you gotta look up in the owner's manual

P0190 - Fuel Rail Pressure Sensor Circuit Malfunction (FRP) The comprehensive component monitor (CCM) monitors the FRP sensor to the PCM for VREF voltage. The test fails when the VREF voltage from the PCM drops to a voltage less than a minimum calibrated value.

• VREF open in harness.
• VREF open in sensor.
• VREF open in PCM.

Verify VREF voltage between 4.0 and 6.0V. Your vehicle has electronic returnless fuel system . A control module controls the fuel pump speed from inputs from the PCM - engine computer from the fuel rail puressure sensor . The modules on your vehicle are on a serial data bus (network) an they send messages from one to the other . The REM - rear electronic module is in charge of controlling the fuel pump through PWM - pulse width modulation . Pulse-width modulation Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a modulation technique used to encode a message into a pulsing signal. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices, especially to inertial loads such as motors Your problem maybe the fuel rail pressure sensor is bad , but could be something else .Hooking up a factory or professional scan tool to check data parameters is the proper way to diagnose .

Does the heater work ? blower motor pushes air out of the vent's ? A/C compressor doesn't engage ? I'm try to figure out what you have going on there . completely dead on dash panel ? Two fuse in the central junction box F2.14 10 amp an F2.20 10 amp these power the climate control panel . Relay one has nothing to do with it . If the fuse's are good you need a new control panel .

Don't worry I'm sure you will get the solution of your problem, just check the link I attached 2000 Ford Lincoln LS Workshop Service Repair Manual

The LS has a hydraulic cooling fan up until the 2003 model year. I had a heck of a time trying to find the overheating problem on my 2001 LS V-8. The degas bottles are known to split and leak . I replaced mine as it had several splits in it. That didn't help at all. The problem that causes the over heating most of the time is the hydraulic actuator solenoid that is on the hydraulic cooling fan pump on the passenger side of the engine. If you have the car running with the hood open and the a/c on hi cool, the cooling fan should be spinning very fast! The fan should make a pretty loud noise. Mine would spin but not at the high speed it should. If the actuator is not kicking on and opening the valve that allows the hydraulic fluid to spin the fan at full speed then your engine will get hot. You can find the actuator online for under a $100. To find where it's located get under the passenger side of the car. Find the pump which is on the front of the engine. The actuator is on the side of the pump and hard to get to and see but take your time and use a good light.. Look for a wire that powers the actuator and it will lead you to it. It is a tight job to replace it but it should take no longer than an hour.

Bank one is on the passenger side of the engine.

Yea , take it to a qualified repair shop that has a scan tool that can show misfire data . That's the best way . What engine ? 3.0 L or 3.9 L . Both have COP - coil on plug ignition system . I have replaced a bunch of these coil's an spark plugs . The spark plug get so worn the spark can't jump the gap an fries the coil and if it goes like that long enough it will short out the driver (transistor) in the PCM engine computer . The last one i worked on cost the owner over 2 grand. New computer , programming , new coils , plugs , plus my labor . Ford Coil On Plug Misfire Quick Diagnosis Methods

The PCM - powertrain control module energizes the A/C clutch relay . Don't know what this other guy's talking about ? No VCRM on your vehicle .Engine computer controls it . PCM . Now if the climate control , heater / A/C is not blowing out of the vent's it's probably the heater blower control module . If you had it to a shop what did they say was wrong ?

need to check the wire harness for shorts

Your AC mechanic is a know nada POS. Your AC is not working because the clutch is not being properly energized so as to turn the compressor which as you indicated is working and fully charged. Either the climate control head you just got is no good, ditto for the low pressure cut off switch, thermostat.. Best thing to do is get a hold of someone who has the AC schematic and can check out all of the electrical components in the way of getting power to the clutch!

run the fault codes first use a quality injector cleaner to clean up the injectors

142536 is firing order for 2004 v6 3.0. Go to www.lincolnvscadillac.com to make sure. don-ohio

Probably Degas bottle leaking under pressure. Is the leak back under the Degas(expansion tank) area ? Don't buy anything but Motorcraft/Ford parts on THAT cooling system. don-ohio

Probably the center (carrier) bearing of the driveshaft or a CV joint at the rear axles. don-ohio (:^)

Took it to the shop , What shop ! Dealer ?

Does not have fuel pump driver module , has rear electronic module ! The difference is it does more then just fuel pump control . I would google it to see what it looks like , then look in the trunk ,under back seat , Have seen them behind back quarter trim panels .

most cars have a pump some place near the gas tank if not inside near the gas pickup but that requires dropping the tank from the car if not follow the leads around where the fuel line is and the pump should be there on the side wall of the car in most cases

Does the engine temperature also take that long to get to operating temp (around 200 F)? If it does, your thermostat may be on its way out. Check your coolant level first.

You just press the switch down.
