850 Turbo Will Not Crank 850

I bought a nice 850 Turbo Wagon with 130k miles for $1500.00 because it doesn't run. The owner thought it was the timing belt. There is a placard under the hood that states the timing belt was last done 4/15/05. The battery is dead so I'm using a jump box to get it to turn over. The motor spins quickly, but does not fire. The motor sounds normal. No loud metal on metal sounds. I pulled the oil cap and the internals are moving. Turn the key, can hear the fuel pump kick in. Is this the infamous cam sensor? Or what do you think. Thanks in advance.

    I went out today and pulled the plugs and check the cam sensor plug set up. The plugs were completely soaked. Appeared more like oil than fuel. Plug wires look good. Cleaned and replaced. No help, still no spark?
    Checked oil level dipstick. Nothing showing??? Poured 4 quarts, still nothing showing???? Any correlation? Help still needed.

      You mentioned that no oil was showing on the dipstick even
      after 4 quarts, BTW you may have to put more like 6 quarts
      in the motor to get it on the stick. Are there any obvious oil
      leaks? If you put 6 quarts in and it does not show on the
      dipstick it has to be going somewhere. cam seals could
      be leaking under the timing cover. Is the motor really clean?
      Did the previous owner clean it out really well (possibly
      to hide the problem?)

      Here is a possible scenario - intake cam oil seal failure.
      If the rear intake cam seal failed, it could easily fill the
      distributor cap and rotor with motor oil which certainly
      would cause ignition problems.

      The rear cam seal on the intake shaft is under the
      distributor cap (technically it would be behind the
      rotor) If the seal failed this would spray lots of oil
      into the distributor cap. Have you taken the distributor
      cap off yet? It's really easy on this car. If it is the seal,
      it is one of the easiest to replace.

      Good luck with it!

    Waiting for your responses. I'm ready. Any help would be appreciated. Thanks

      the capacity of the oil pan is near 6 or 7 quarts so it is normal you can pour a lot of oil into it. I would check if you get voltage to the primary side of the coil. If something is happening on the primary side, you narrow the problem between it and the spark plugs.

      Try to disconnect the air mass meter and then crank. Maybe it is bad (those are a lot more raliable than the 240 MAFs but give it a try) Disconnecting it will put the engine management system in limp home mode and the car will be able to start and idle but will die if you depress the gas pedal.

      Dont forget that once the engine runs, you will have to change the oil since it will be soaked with gas.

    Are you getting any error codes? Are the plugs wet with gas after cranking? Maybe do a compression check also.

      I'm not getting anything from the code reader at all. I attempt to crank for a period of time hoping to get some type of reading. After connecting to socket A2, no beeps at all. Don't know if that is due to the car not cranking and having nothing to determine. Plugs are getting gas. Can smell the gas after numerous attempted cranks. Any thoughts on the timing belt or cam sensor??

        Back to basics...
        Car needs three things to run - fuel, spark, air.
        You say plugs are wet - that's good, but is the fuel free of water or
        other contaminants?
        Spark? Easy to check.
        Air? Could be a number of causes, from broken vacuum hoses to clogged
        intakes. (Lot's of info in the archives).
        Good luck; wish I could find a deal like this.

        If you can see the camshaft turning the timing belt must be ok. You can remove the upper part of the plastic cover on the passenger side (held on by 1 bolt) if you want to inspect it directly.

        Normally you can read the codes if the ignition switch is on (dash lights illuminating). No need to have cranked the engine. If you are not turning up codes, I would assume the various sensors must be functioning more or less ok, unless someone has recently read and reset the codes.

        Evidently you are convinced there is no spark? Did you try the old fashioned test of removing one wire and watching for a spark to jump to ground from the end? If failed, how do distributor cap, rotor and secondary wires look? Is there a mechanical problem inside the distributor?

        If the secondary circuit seems to look ok, then you need to go to primary side - including ignition switch and main relay. Do the accessories in the car (the ones that normally work only with ignition on) work?

        Cam position sensor is also a possibility, but I'm not sure how many verifiable failures there really are - it's a rugged device.

        If you think the car is flooding - ECT sensor or its wiring may be bad, or fuel pressure way too high, though I would expect the car to start then quickly die.

          Forgot to mention. Car is getting fuel. Check fuel rail and it is working properly.

          Thanks. I'll check during the daylight tomorrow. Any other ideas would be appreciated.

          I tried spraying some engine starter in the intake. No fire. So spark is top of the list. Pulled the plug wire, no spark. Coil? Main Relay? etc..

          Thanks
