Mercury Sable 97 does not start

Question From oddgca on Mercury Sable 97 does not start

Mercury Sable 1997 Wagon 3 ltr
160000 km

Sable 1997 not starting

The engine cranks well. Tank is ¾ full. Fuel pump seam to work. I noise is heard when listening at the fuel filler cap and the ignition is switched on. By using a digital OBD2 car reader, no new trouble code is seen (the car runs since about one year without a working camshaft position sensor. Code PO340 is present. However I was told by an expert, that the car will function well without it as long the crankshaft position sensor works).
The car worked well for two days, after it was not used for about four weeks. The engine stopped on two occasions after it was started, but restarting was successful. It failed to start after it was parked overnight at very low temperature of about -15 C (10 F). Heating up the engine by a block heater and an additional heater inside the engine compartment did not solve the problem.
I assume that either the fuel supply is blocked or the ignition does not work. Tomorrow I will check the ignition by removing a spark plug and checking for proper sparks. Could it be that the fuel filter is frozen?
How can a proper fuel flow be checked? I learned that before touching any fuel line the fuel pressure should be released. How and where can it be done?
I would appreciate very much any help in the matter.
Otto

Response From oddgca

It is a 3.0 l OHV engine.

Is batch firing detrimental to the engine, ignition coil, spark plugs, injectors, PCM and others? I gave up looking for a low cost camshaft position sensor a time ago. I will try again to find one at a reasonable price.
I got the engine started after checking the ignition sparking, heating up the engine, fuel filter, fuel rail, adding Gas Line Antifreeze and Gas Treatment to the fuel. I hope the car will start again after the cold night coming up.

Response From Hammer Time

I will try again to find one at a reasonable price.

What does that mean? How are you determining what should be a reasonable price for that particular part. It costs what it costs.

Response From oddgca

It is an old car and old cars don't hold forever in the harsh climate of Canada. Maybe it is time to buy a newer one.
Happy New Year

Response From Discretesignals Top Rated Answer

3.0L OHV or DOHC?

There is a pressure test port on the fuel rail you can connect a fuel pressure gauge to.

You do need to have the cam shaft sensor problem fixed. It will run, but the fuel system is batch firing the injectors instead of using the sequential method. If it is the OHV engine, a common problem is the cam shaft synchronizer wears out and wipes the sensor off and blends it up inside the housing. You don't want the synco locking up because it happens to drive the oil pump.

Engine knocks when cold

Question From scbett57 on Engine knocks when cold

I have a 1997 Mercury Sable with the standard 3.0-liter engine with 105,000 miles. The engine knocks/taps once I start the engine while it is cold. Once the engine reaches normal operating temp, the knocking quits. It is a very fast knock and sounds to me like the lifters, although I have not heard what a piston slap sounds like. It also sounds like numerous lifters knocking. Leading up to this problem, I was trying to solve a heater problem, not putting out hot air. I started with the basics, replacing the thermostat (factory temp of 195), flushing cooling system and finally replacing the water pump. The pumps impeller blades were completely corroded away. Surprisingly, I was not having over-heating problems other than occasionally; the temp gauge would increase slightly while stopped for a light or such. Once the water pump was replaced, I noticed the temp gauge still increasing while stopped with the engine running. The reservoir was empty so I bled the cooling system with no change. I was loosing coolant but no leaks. My oil was clean of coolant (no milky foam) but did notice more exhaust than usual and missing at low RPMs. I figured it to be a head gasket and purchased Bar’s Leaks Head Gasket Fix, followed the instructions and have not lost coolant since. A couple of days after the gasket fix is the time when the knocking started. I have just changed the oil, which I do religiously, every 3,000/3,500 miles, and with no change – still knocking. I did not have any of these problems (other than the heater) before I changed out the water pump. What could be causing the knocking and why the problems after changing the water pump? Unfortunately, this has not solved my heater problem, which I am afraid the heater core is bad.
Thank you for replying.Steve

Response From nickwarner

when its only doing it cold, I would guess its your lifters. You can replace them or just run a thicker oil. I have had some success quieting them with Lucas oil. As to your heater, the core is plugged tight with rust. There's a trick you can try if you want to avoid the fun of trying to get that thing out. Unhook the heater hoses from the firewall and put some lengths of hose on it that can reach out of the engine compartment to a pail. Go to Harbor freight or somewhere like it and find a small cheap 12v fluid pump. Get some CLR cleaner too. Circulate CLR through the core for several minutes, then flush well with water. CLR is corrosive so get it all out. Blow it out with air, hook the heater hoses back up and bleed the air out. I did this last week to a 98 Sable that had the same problem and the regular coolant flush stuff couldn't fix it. January is a bad month to be without heat

Response From jason32038 Top Rated Answer

Sounds like sludge preventing oil flow to the valve train or weak oil pump. Wrong viscosity oil?

Response From re-tired

Its hard for the average person to tell if they have a spark knock (pinging) or lifter bleed down (rattle) . If pinging it could be due to carbon buildup on a high mileage eng . The slight loss of compression by head gasket was fixed with the bars leak . the increased compression is now causeing ping ,,,IF this is the case try some injector cleaner for the next fewfillups. If the cause is lifter bleed down it could be normal wear. If so try going up in the weight of oil , say a 20w/40 or straight 40 , this may help. IMO 3k is to short a mileage for oil change's. I have a 93 chevy pickup with 240k and have changed oil every 5to 6 k since new , using whatever was on sale (always a name brand tho). Recently changed valve cover gaskets , heads were clean , no sludge . But by all means do what your comfortable with .
