It is my aunts vehicle and she bought it with a motor. A little bit down the road the engines timing chain jumped and her now ex husband sold the motor. We bought a used motor from a salvage yard and installed it into the Mountaineer and it will turn over and start with ether in the throttle body. We are getting fuel in the fuel rail but none in the throttle body. What do we do about this problem?
Hello. The
following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem. The
engine and the automatic transmission (transmission control is only
for automatics, engine is still computer controlled no matter the
transmission type) in this vehicle are computer controlled and in
most cases when a fault occurs a fault code is stored in the memory
of the computer control module. There are exception to this, such as
the Mass Airflow Meter and fuel pressure problems. What must be done
is to have all the basic testing done such as a scan of the system
for fault codes as well as a check with a live data scanner tool for
engine functions that are not within range of normal, a trained
technician is required to know what is correct and what isn't, then
based on careful diagnostics done from a factory repair manual the
correct part is replaced or the wiring repaired or the computer
replaced (known as the PCM), which is very rarely the problem. Other
basic checks must be done as well such as mechanical problems with
the engine as well as engine state of tune and mileage on the engine.
The transmission can have mechanical issues as well such as no gear
engagement at all or a failed pump or other pressure related
problems. Also engine mechanical problems ca cause many
drive-ability related problem such as rough idle and other symptoms

Hi, maybe there's a problem in your starter or your battery consume more electricity.

Go to the local parts store, have them check the codes (they will do this for free usually). It will tell you what sensor needs to be checked/replaced. Once the part is replaced, it will clear on its own. They can also reset the code, but it will come back if the trouble persists.

I am having the same problem. same van: 97 Mercury villager van 3.0 engine. I have been reading online for a while and everyone with same year and type of van are having the same problem. It is your Crankshaft Position sensor. you can get it at autozone for about $35 after tax it is just a pain to find. It is mounted in motor in front of your crank pully.

Actually I am hessitant to respond to this one. The problem you are having COULD be many things, however my take is different than the others you seem to have. I believe that you are having timing issues caused by a Crankshaft Positioning Sensor, and/or Cam Positioning Sensor. Thesee are how the computer knows where they are and adjusts timing to make the engine fire at the correct time, thus it is called timing. The computer makes these adjustment is literally THOUSANTHS of a second, and if the sensor is off just a little especially at very high, and very low revolutions you will have a miss, which will at high RPM's "pop" due to it wanting to stall but because of the RPM's keep momentum, and pops but keeps running but at low RPM w/o that momentum, just stalls. I pray this helps you understand WHY I think you may have timing issues and why.
