Installed timimg belt on a 05 Chrysler Pacifica 3.5L V6. Marks are aligned correctly with engine on TDC. But car starts like timing is off. Has no power. No codes present. Running out of ideas. Can so
Triple checked timing mark alignment with engine on TDC. Cleaned throttle body and IAC. Replaced spark plugs, upper intake gasket, and EGR valve. Triple checked everything I disconnected to make sure all sensors are plugged back in and vacuum lines are connected properly.
dont take soo much in consideration after you have make all this things, some time is on only for any wire faulty, or a shrt electrical arc in any place in wire system. ask auto tap mechsnics for this maybe they have similar case before.
Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

If I remember correctly, it should be behind the inner wheel liner on the drivers side behind the bumper. Just pull the drivers wheel and the liner is easily accessible.
I just recently experienced the same problem. The timing is 180 degrees out. Unfortunately the only way to correct it is to take the engine apart again. Set the right hand camshaft to TDC by using the marks on the timing gear for that bank. The left will follow to the degree it can although you will have to manually hold the cam in position when you put the timing gear back on. Now you can remove the timing chain. The crank TDC indicator may not be right on but it will be close. Rotate the crank CW one revolution to the point the TDC marks are lined up. Now install the timing chain according to the instructions. The timing gears on the camshafts will only go on one way as the bolt holes are slightly off the extreme diameter of the gear. If you put the chain back on making sure that all the marks are proper, she'll fire on the second cylinder up. Not a fun job I know, but when everything works right, you do get a sense of satisfaction.
Remove the right-hand splash shield and the crankshaft pulley.

WARNING If the camshaft belt is being reused, mark the direction of the camshaft belt to the rotation of the camshaft prior to removal, or premature wear and belt failure could occur.
Loosen the tensioner pulley bolt and relieve the tension on the belt by disconnecting the tensioner tab from the timing cover back plate.
Slide the belt off the sprockets.
Inspect the belt for wear and replace as necessary.

To install:
If, for any reason, the engine was disturbed, the camshafts moved or the sprockets replaced, perform the following procedure:
NOTE: Make sure the correct notch in the pulley is indexed to the lower cylinder block.
Position the crankshaft just prior to Top Dead Center (TDC).
If not already done, locate and remove the plug bolt by the Crankshaft Position (CKP) sensor (refer to the illustration) and install the TDC timing peg.
Rotate the crankshaft clockwise against the TDC peg.
NOTE: Installation of the alignment tool into the exhaust camshaft may require the camshafts to be rotated clockwise.
Install the camshaft alignment tool on the back of the camshafts.
Install the timing belt and engage the timing belt tensioner tab into the upper timing cover backplate.
NOTE: A 3⁄8 inch drive, 10mm, 2 inch torque adapter offset is required to tighten the tensioner bolt.
Using a 6mm Allen wrench, adjust the tensioner until the index marks are aligned and tighten the bolt to 17–20 ft. lbs. (22–28 Nm).
Rotate the crankshaft clockwise against the TDC alignment peg, then remove the camshaft alignment tool.
Remove the TDC peg tool and install the plug bolt.

Install the water pump pulley and the splash shield.
Locate and carefully remove the access plug from the upper portion of the timing cover.
WARNING When turning the engine over by hand, ALWAYS rotate the crankshaft in the proper direction of rotation, otherwise the timing belt might jump one or more teeth due to the configuration of the belt tensioner.
Turn the engine CLOCKWISE (in the normal direction of rotation) to set the engine at Top Dead Center (TDC) of the No. 1 cylinder by aligning the O mark on the belt cover with the O mark on the crankshaft pulley.
NOTE: If no timing mark is visible through the access cover when the O marks on the crank pulley and cover are aligned, the engine may be on No. 1 exhaust stroke and not the compression stroke (the camshaft is 180°away from No. 1 TDC). If so, the crankshaft must be rotated one full turn to bring the No. 1 piston back to the top and the camshaft around to close the No. 1 intake and exhaust valves.
With the O marks aligned, look through the access hole in the cover to confirm that the timing mark on the camshaft sprocket aligns with the pointer on the inner belt cover. If the belt timing is incorrect, the timing cover and belt must be removed for further inspection, possible replacement and correct installation. For more details, please refer to Section 3 of this manual.
get the #1 piston top dead center, then line up the camshaft gear and the crank gear to line up with the timing marks on the engine after you find those marks slip the belt on making sure all the timing marks havent changed then check to see if the tensioner for the belt is set with the proper tension then check to see if the belt isnt slipping remember it will be spinnig at high RPMS
If you have the harmonic balancer still attached you can align the timing marks with 0 degree to get the main block aligned. With the head removed you can turn the cam shaft till the number 1 valves are both closed and the number 3 exhaust valve is open. Take the time to inspect the valves as well. This vehicle did not come with no contact valves so when the belt broke it is possible the valves made contact with a piston and bent. I highly recommend you get the Haynes Repair manual on this vehicle from the local auto parts store as it has detailed instructions on how to get back to TDC if this happens. It also has Pictures on this. Because this belt goes around 3 timing marks aligning those after you have the pistons at TDC if you align the timing marks on the different sprockets/pullies the timing for teh valves will be correct.
hi from uk assume you have renewed c/belt and balance shaft timing belt? if so? and sure your timing marks on cams and the c/shaftcog are correct ? the oil pump also correctly aligned with marks? and the balance shaft gear also has time marking ? want to run thro how and which marks you have aligned and at TDC No1 all belt/s have to be aligned ??
How did it run prior to all the work?
