    thank u for the responses i agree the motor is backwards and a pain to do just about anything to.I do have one more question if i may, when i turn the engine over there is no compression and i mean none there is so little at first i thought it was my starter not engaging, it sounded almost the same but everything is spinning the crank all the pullies and drive belts, it is as plain as day that there is no compression and when i turned off the car for the last time i had just left the shop where they told me the timing was out about 6 or 7 teeth when i got home turned the car off it never started again could it have jumped again putting it that far out of time that this zero compression thing was the outcome????

    Ok thanks I fixed the problem and ya it was the timing, and man was it way out 180 on the intake side (by the way my laser is a 2.0L DOHC)so i noticed this set the timing again and presto it worked, for a bit anyway.It jumped time again during the test run, so my only thought is the tension on the belt.i'm hoping this will fix it for good because when i had it running for the 20 min. or so it ran perfect.not a single sputter , hesitation,nothing.So new timing belt , new plugs, wires and make sure the tensioner is at the proper ft-lbs(from what i understand the tensioner's tightness is based on the lbs of tourque you apply)

    MY Apologies on the error....but this Engine is backwards!

  • Patrick Rayome May 08, 2010

    Good Morning!

    There is a 100% probability that the Timing Chain has broke.

    Did you check all Cylinders for Compression? If the Timing Chain has broke, or is so far off the mark: there is little to no chance of compression.

    While attempting to Start: the Crank will turn and the Belts and Pulleys on the outside will turn. Generally: the Starter turns the Flywheel, turning the Crankshaft, turning the outside pulleys. The Timing Chain inside however - turns the Camshaft(s) in sequence to the Crankshaft to open / close the appropriate Valves at the appropriate time.

    However if:

    1. The Timing Chain is Broke the Camshaft(s) (still not sure what engine you have) inside will not be turning. Valves will sit there in the Opened Position = no compression.

    2. The Timing is way off - the Cam(s) will turn but during the Compression the wrong Valves will be Opened when they are suppose to be Closed = no compression.

    I strongly suggest you take the Valve Cover off and reattempt Starting. Watch to see if your Camshaft(s) are turning. NO TURN = Timing Chain is Broke. If they are turning, and you have no compression on all cylinders = Timing is way off. You can also take your Oil Filler Cap off (without taking the Valve Cover off) and with a partner attempting to Start, watch inside (with light) for any movement.

    Let me know if this helped, or if you have any additional information or questions. Don't worry about asking more questions - that's what I'm here for; but I strongly suggest you buy either a Haynes or Chilton Manual available at most auto parts stores for around $25-$30. The information, procedures and knowledge in there will be a great assistance to you.

    Make sure you Grade me also....this is our only payment - other than helping people for free - that we receive.

    You are right about the Torque. 35-ft-lbs on the Tensioner.

    Click on the following: direct Free Link. It has some great diagrams and information.

    Make sure you scroll down to the information about the Left Silent Shaft and follow that procedure.

    Take Care and Good Luck!

Where is the ecm located on a 92 Plymouth acclaim


NO ECM (engine control module). The skamatic does show PCM powertrain control module. Look under the hood, near the back of the motor. On the frame rail or the fire wall. Power Distribition center (PDC) should be ther as well.
