My 97 intrepid 3.5l acts like it is not firing, I removed inspection plates brought it to TDC and everything is in time (belt is good and tight all marks line up) . I tried cranking again it fired and ran great. I cranked it several times. After replacing all parts it once again will not fire. any ideas what the problem may be?

YOU NEED TO CHECK DARK GREEN/ORANGE WIRE AT IGNITION COIL WHEN CRANKING ENGINE FOR POWER..IF NO POWER,SHUTDOWN RELAY IS NOT BEING ENERGIZED..THIS ENGINE ALSO HAS CAMSHAFT POSITION SENSOR ON END OF CYLINDER HEAD..ENGINE CONTROLLER NEEDS CAM AND CRANK SIGNALS TO ENERGIZE THE SHUTDOWN RELAY..UNPLUG CRANK SENSOR AND CHECK VOLTAGE ON ORANGE WIRE..SHOULD HAVE APPROX 8V..IF NOT..UNPLUG CAM SENSOR AND SEE IF 8V SUPPLY RETURNS..IF NO POWER TRY UNPLUGGING VEHICLE SPEED SENSOR LOCATED IN TRANS HOUSING WHERE RIGHT SIDE AXLE COMES OUT OF TRANS..IF 8V RETURNS..THE SPEED SENSOR IS SHORTED INTERNALLY..THESE 3 SENSORS SHARE THE SAME 8V SUPPLY CIRCUIT..WITH SPEED SENSOR UNPLUGGED,PLUG CRANK SENSOR BACK IN AND TRY TO START ENGINE..HAVE SEEN THIS SAME PROBLEM AT WORK RECENTLY

SOURCE: just replaced engine in my 97 its a vortec brought

you are a tooth off,or 180 degrees out .put your finger in number 1 spark plug hole ,have someone tap the key until compression blows out,check crank marks at tdc, remove cap,rotor needs to point #1 on cap. you may need a shop to set timing.

SOURCE: I'm replacing timing belt and

Here is a few diagrams of the timing marks. Be sure that you check the marks after the tensioner has been installed as well because installing the tensioner tends to slightly re-adjust the positions of the cams as it takes up slack on one side.

Be carful when turning the engine (by hand) because these engines are an interferance engine and the valves can contact the pistons. After everything is installed and tight, rotate the engine by hand twice and then recheck that the marks are good to go.

If you haven't replaced the water pump, I highly recommend you do it now.

Resetting timing after replacing head gasket

Do you have the timing belt on and the tensioner set correct? If so, just rotate the crankshaft around until the notch on the crank sprocket is lined up with the pointer on the oil puimp housing (TDC). Now the camshaft sprocket's notch or pointer should be at the top and exactly in line with the mark on the rear timing belt cover. If it's not correct, you'll have to release tension on the belt, remove it, and set the camshaft to the mark. But before you do that, turn the crankshaft back (counterclockwise) just three notches. Then you can turn the cam to line up, then return crank to line up, and continue with belt installation, setting the tension, and re-checking timing marks after rotating the crankshaft a couple of revolutions. Once you know the timing is set to TDC, no further timing adjustments are possible, because the computer controls timing. I don't know how important it is, but just to let you know: Chrysler recommends after belt removal or replacement that one perform the "crankshaft and camshaft relearn alignment procedure" using the DRB scan tool (Chrysler's scanner device) or equivalent scan tool.
And the firing order on all four cylinder engines is the same: 1 3 4 2.
I hope this helps you out. Cheers.

I have a 2002 pt cruiser with a 2.4 litre motor. I've tried to install the timing belt but it does not line up with the 4 scrib marks. I do not know how to rotate the cams in the right order for the belt...

It is typical to have to stretch the belt a tad as you install--needs to be tight across the cam sprockets and from the right cam to the crank gear. Then the tensioner should take up the slack on the other side. 0996b43f80209592.jpg

0996b43f8020873b.jpg enlarge_icon.gifenlarge_tooltip.gif Fig. Proper timing belt routing

  1. Set the crankshaft sprocket at TDC by aligning the sprocket with the arrow on the oil pump housing.
  2. Set the camshafts timing marks so that the exhaust camshaft sprocket is a 1 / 2 notch below the intake camshaft sprocket.
  3. Install the timing belt by starting at the crankshaft. Go around the water pump sprocket, idler pulley, camshaft sprockets and the tensioner.
  4. Move the exhaust camshaft sprocket counterclockwise to align the marks and to remove any slack.
  5. Insert a 6mm Allen wrench into the tensioner opening on the top plate of the tensioner pulley. Rotate the top plate counterclockwise. The pulley will move against the belt and the tensioner setting notch will start to move clockwise. Continue to move the top plate counterclockwise until the setting notch is aligned with the spring tang. Using the Allen wrench, to prevent the top plate from moving, tighten the tensioner lock bolt to 220 inch lbs. (25 Nm). Make sure the setting notch and spring tang are still aligned after the lock nut is tighten. If not repeat the procedure.
  6. Remove the wrench from the belt tensioner.
    NOTE When repositioning the crankshaft to the TDC position, this must be done during the clockwise rotation movement. If the TDC is missed, rotate a further two full turns until TDC is reached. Do not rotate the crankshaft counterclockwise as this will result in improper tensioner settings.
  7. Rotate the crankshaft two full revolutions and verify that the TDC marks are properly aligned.
  8. Check the spring tang is within the tolerance window, if not repeat the previous two steps.

How to change my timing belt for a 97 mecury mystique gs 2.0

There are so many steps. After removing everything so you can get to the timing belt you need to make sure you have the engine set so the #1 Cylinder is TDC. Remove the old belt and re-install the new one. If you need step by step directions on how to do any of this I recommend you get the Haynes Repair Manual for your vehicle since it will show you those and give you instructions on how to make sure your at TDC. If you try putting that belt on without being set to TDC the engine is not going to run correctly.

Doing Top Dead Center(TDC) before T-belt

It is important that you turn the engine in the correct direction. To achieve TDC firing stroke remove spark plugs insert a plasic straw into the number one spark plug hole and proceed to turn the engine over observe the straw keep turn ing the motor until the straw travels upward when it stops moving up stop turning, you will know you are at tdc by looking at the timing marks down on the crankshaft pulley the notch on the pulley should line up exactly to the number zero on the timing plate at the front lower part of the motor very close to the crankshaft pulley turn the motor over again and again until you line up the notch on pulley with the number zero you may need to clean the numbers off on the timing plate or front cover.

How to you install a water pumpon a 3.5 97 dodge

Remove the hood bracket bar, 4bolts, then the fan shroud assembly, then the belts, belt adjuster, and timing covers, line up the cam gears, crank gear to the marks , cam has 1 dot, they line up to timing housing 2 dots, (single dot to middle of the 2 dots), crank has 1 dot to mark on the oil pump housing to your right of crank gear, thats TDC. now remove the timing belt tensioner, 2 bolts, and remove the belt, if the pump has leaked, replace the belt, and tensioner if it is NOT metal Pulley, the fibre one will break down from the antifreeze. its a good idea to replace the water pump housing orings behind it, ac bracket has to come off, as the right cam on engine, this not a retiming iussue with the gear. GOOD LUCK. RDJRP
