Have you ever replaced the fuel pump relay?
No, I've tried to find out where it is but I am getting conflicting answers. Do you know where it is?
Under the Hood to the Fuse box. Take off cover, then look and fuses lift off to expose relays and larger fuses underneith

SOURCE: 2001 v6 escape rough idle when cold
To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).
The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.
My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.

DTC
P1131 DTC P1151 indicates the system is correcting RICH for an overly LEAN
condition. The Heated Oxygen Sensor (HO2S) voltage is less than 0.45
volts. This is usually due to a vacuum leak after the MAF. It can also
be caused by a bad PCV valve or PCV system hose.
It can also be caused by low fuel pressure or a plugged injector.
Start with the simple and clean the MAF and the IAT sensor. In simple terms, the engine is running lean and is being compensated by the ECM. P1131 is bank 1 and P1151 is bank2
Good luck and keep me posted.
