My 1995 Dodge Caravan 3.3v6 has jumped time. The first time in I put new cam and crank grears and new chain. alined crank and cam @6 & 12. Did not know about the color links. Went in the 2nd time and put every thing in order as the repair manual said. When it did fire it sounded like it was off one tooth. Went back in and have check every thing and replaced both cam and crank sensors. Still did bot correct the problem still sounds like it is off time. Is there a special tool to set the position of cam, crank, and chain marks to where this beast will crank up. I am going in it for the 5th time and would love to get it fired this time and stay running. I am starting to think that I am 180 degrees off and need to turn the crank one full revolution.

I had one where the gauge cluster isnt working and van wouldnt start or would start and shut off after 5 seconds so make sure gauges are working

Not sure but if doing belt yourself I will give you important tips. 1) before removeing T/Belt set engine to TDC nr 1 there should be marks on the crank and cam (s) gears that line up with a mark on the block / head. 2) prior to removeing tension to belt get liquid paper & mark cam gear(s) & crank gear to point on block / head. 3) mark T/Belt to cam(s), crank, balance shaft if fitted. 4) release tension & remove belt. 5) transcribe marks from old belt to new belt & make sure correct amount of teeth. 6) fit new belt so YOUR marks line up. 7) have tensioner suply presure to belt. 8) turn motor twice by hand to make sure pistons no hit valves 9) Make sure YOUR marks line up if YOUR marks line up it has to be right. 10) Very IMPORTANT if spring tensioner lossen locking bolt again to take up extra slack in belt. 11) tighten locking bolt. 12) put back together.

By :"specs" I assume you need install position? To index the gears, whne you take it apart, turn the crank pulley 'till the timing mark aligns with the "0" on the timing scale. Don't turn the crankshaft again. When you are ready to install the chain, locate the mark on the crank gear and align the mark on the cam gear so they point to each other. The mark on the crank gear should be at 12 o'clock and the cam gear mark at 6 o'clock. Make sure when you put the cam gear on the cam that the location pin fits into the gear to position it correctly. Jeep recommends that after putting the chain and gears on, you rotate the engine by hand and place the crank mark at 6 o'clock and the cam gear at 3 o'clock, then count the number of pins in the chain (pins, not links) between those two points. There should be 15 pins. If you are rebuilding the engine and have the cylinder removed, it's a good time to check the front crank pulley (some have the outer ring move on the rubber). Put a piece of flat steel across #1 cylinder with a bolt through the steel extending into the bore center. Turn the engine by hand 'till the piston contacts the bolt. Make a mark on the pulley and turn the engine in the opposite direction till contact is again made. Your timing mark on the pulley should be exactly between the two marks you made. If not, make a new mark at that point and use that as your actual TDC reference. If it is radically off, replace the pulley.
When setting up cam position I always use a degree wheel. If you are installing an aftermarket cam
its important to do that. If you're just replacing a stock chain, You will be fine with the method I've outlined.

Do a cylinder compression test, some times will bent valve's with timing chain failure.

To align both sets of timing marks, turn engine crankshaft to the right with belt on cam and crank. Once you have done this the crankshaft alignment mark (on front of crankshaft gear) will line up with mark to the rear of gear on engine block.The two cam gear timing marks should be alines across from one another. The right cam gear is the intake side and the left side is the exhaust side. After removing the belt turn the exhaust cam down 1/2 notch. Timing mark on exhaust 1/2 notch down from the intake side. Install new belt and recheck everything to make sure it's all correct. Hope this will help you.

DONT MESS WITH THE DISTRIBUTOR, JUST REPLACE GEARS AND TIMING CHAIN ALINE BOTH CRANK AND CAM GEARS DOT TO DOT CRANK GEAR DOT UP AND CAM GEAR DOT DOWN.

Im assuming it is an engine that uses a timing belt. It sounds like the belt has jumped 1 tooth. if it only jumped 1 tooth than the computer will compesate the timing so it is possible the sensors will say they are ok. If it is a motor that uses a chain than it problaly needs a new gear/chain set.

I’m happy to help further over the phone at https://www.6ya.com/expert/david_c087e4b7d13c0163

Align the chain with the colored links on the chain over the marks on the cams.Twin cams Have a small hole on the cam gears that will align with a hole in the front of head.Crank Gear has a pip mark that goes straight up.colored links on crank go to the 5 & 7 Oclock position on the lower crank gear with pip mark on crank gear at 12:00.Hope this helps

There is a very good possibility that the timing is 180 degrees out. Verify that the number one cylinder is firing on the compression stroke. I 've had this happen to me in the past when I first started building performance engines. The "School of Hard Knocks" was a very tough teacher, if ya know what I mean.

I would look there before going anywhere else.

Good Luck

Hi..
On your problem with the Caravan.

If you Have replaced the Crank and Cam sensors. And the Code Cam/Crank Correlation sensor.
Is found.
Normally this code is present When the Timing belt or Timing Chain, Is out of time 1 or more dents
On the timing due to Skip of the timing belt or Chain.

But don't forget check the connector at the sensors. For any damaged or corrosion on the pins.
Ok.. I hope this help to try diagnostic your car.

Thank you for use fixya.
