P0191 is fuel rail pressure sensor or circuit low input. This indicates that fuel pressure is too low or the sensor is faulty or the circuit is at fault The fuel pressure should be tested to see if it is spec.and circuit test preformed the location of this sensor and testing needed to make an accurate repair requires some degree of skill and someone that is comfortable doing this type of diagnostic repair

SOURCE: Where is the starter located on a 1993 mercury sable engine

trace the big cable that came from the positive terminal of your battery. at it's end is the starter.

or if it passes trough a big relay, then there is another big cable from that relay that would go down to the side of the engine, either left or right, that would be the starter.

tnx 4 using fixya,

SOURCE: mercury sable 2001 duratec engine DOHC I get check engine light and diagnostic code PO401". Any suggestions?

Barring any vacuum leaks, P0401 is indicative of a bad EGR valve. Hope this answers your question. Best of luck.

SOURCE: I have got a P0171 & P0174 engine codes on my

P0171 System Too Lean Bank 1
P0172 System Too Rich Bank 1
P0173 Fuel Trim Bank 2
P0174 System Too Lean Bank 2

OK, that's a partial list of codes, the fuel delivery is controlled by the oxygen sensors, so it's possible that something in that area could be causing your problem.

However, it could also be clogged fuel injectors that can't deliver enough fuel to the cylinders compared to the air that is pulled into the engine.

Try some fuel injector cleaner for that poured into the gas tank.

How does it run?
Does it miss at all?

2002 Mercury sable misfiring only on cylinder 3


Can't believe some the lame answers here. Anyone having this issue check the PCV hose where it attaches too the air intake, the rubber breaks down and develops a leak. But these engines also have wiring issues that causes crankshaft sensor to fail at startup or under 1000 rpms causing the computer to shoot a code and trigger the engine light. I have these issue cause the above problem.

Engine Code 301


Code # 301??? That is NOT a valid Diagnostic Test Code (DTC) for the engine control system on a 2000 Mercury Sable.

Assuming that you mean P0301, that is a cylinder misfire code that is identifying number 3 cylinder as the cylinder with the misfire problem. MANY things can cause a cylinder to misfire including spark plugs, spark plug wires or boots, burnt valves, broken valve springs, blow head gaskets, cracked cylinder heads, bad or dirty injectors, faulty injector control circuits, Failed ignition coils...the list goes on....proper diagnosis required.

yes about the upper intake and the only way i know how to check the coils is with a engine anilyser or if the check engine light comes on then you can have the codes pulled and that will tell you which cylender is missfiring this engine has a indevidual coil for each spark plug so thares 6 of them and thay slide right down over the sparkplugs
