SOURCE: 2000 dodge caravan, 3.3, no start, new cam sprocket and timing ch

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

The Cam Gear has a hole it it. That what GM uses for a mark.. Gotta love them young engineers at GM for improving an age old way of just putting a diamond mark on tooth instead. LOL

5.4 triton motor rebuilt with brand new heads do I sill have to take out cam follers to put on cam phasers and time or will it line up


If you just did the heads and didn't wedge the timing changes in place, No you don't. Because have to remove the front timing cover and reset the timing. You also needed to remove the followers before removing the head. This sets the crankshaft in the right position for installation of the phasers. If you didn't do that, remove the timing cover. If you did, then yes, the followers have to come out. This takes pressure of the cam so it doesn't move while installing the phasers.

How to lline up timeing marks


on the crank there is a mark on the engine a mark its like a line on the backside of the engine and a spot on the crank sprocket on the top at the cam should have a hole in the center of the cam sprocket with a red line on the head top near valve cover it should line up properly or if you have 2 marks on the cam sprocket -- one on each side of the sprocket and on the engine side or cover should have 2 marks as well that line up do not take off the timing belt until you have all the marks properly lined up then you can remove the belt but do not turn over the engine without installing the new belt

REMOVAL & INSTALLATION

4.3L, 5.0L, 5.7L and 7.4L Engines
See Figures 1, 2, 3, 4, 5 and 6

  1. Remove the timing cover. This will allow access to the timing chain.
  2. Crank the engine until the timing marks on both sprockets are nearest each other and in line between the shaft centers.

Fig. Fig. 1: Crank the engine until the timing marks on both sprockets are in line

  1. On 1996-98 vehicles remove the crankshaft position sensor reluctor ring, if equipped. On 7.4L engines tool J-41371 or its equivalent puller must be used to remove the reluctor ring.
  2. Take out the bolts that hold the camshaft gear to the camshaft. This gear is a light press fit on the camshaft and will come off easily. It is located by a dowel. The chain comes off with the camshaft gear.

0996b43f80219acc.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 3: Remove the camshaft gear and timing chain
A gear puller will be required to remove the crankshaft gear.
To install:

  1. Without disturbing the position of the engine, mount the new crankshaft gear on the shaft, and mount the chain over the camshaft gear. Arrange the camshaft gear in such a way that the timing marks will line up between the shaft centers and the camshaft locating dowel will enter the dowel hole in the cam sprocket.
  2. Place the cam sprocket, with its chain mounted over it, in position on the front of the truck and pull up with the three bolts that hold it to the camshaft.
  3. After the gears are in place, turn the engine two full revolutions to make certain that the timing marks are in correct alignment between the shaft centers. Tighten the camshaft sprocket bolts (and nut on the 4.3L) to 21 ft. lbs. (28 Nm) on 1988-95 models. On 1996-98 models, tighten the bolts to 18 ft. Lbs. (25 Nm). On the 7.4L, tighten them to 20 ft. lbs. (26 Nm) on 1988-95 models. On 1996-98 models, tighten the bolts to 25 ft. Lbs. (34 Nm).

When installing the crankshaft position sensor you must use install a new oil ring seal onto the sensor.
  1. Install the crankshaft position sensor reluctor ring (if equipped), onto the crankshaft until it is firmly seated against the crankshaft sprocket. On 1996-98 7.4L vehicles replace the reluctor ring with a new component.
  2. Install the front cover, torsional damper, water pump and the radiator.

Doesn't have one , not needed with Camshaft Actuator System
The camshaft position (CMP) actuator system is used for a variety of engine performance enhancements. These enhancements include lower emission output through exhaust gas recirculation (EGR) control, a wider engine torque range, improved gas millage, and improved engine idle stability. The CMP actuator system accomplishes this by controlling the amount of intake and exhaust valve overlap.
The camshaft position (CMP) actuator system is controlled by the powertrain control module (PCM). The PCM sends a pulse width modulated 12-volt signal to a CMP actuator solenoid in order to control the amount of engine oil flow to a Cam Phaser passage. There are 2 different passages for oil to flow through, a passage for cam advance and a passage for cam retard. The Cam Phaser is attached to a camshaft and is hydraulically operated in order to change the angle of the camshaft relative to crankshaft position (CKP). Engine oil pressure (EOP), viscosity, temperature and engine oil level can have an adverse affect on Cam Phaser performance. The PCM calculates the optimum cam position through the following inputs:

I need a diagram of timing chain replacement Thank You


During most engine rebuilds, a completely new timing assembly should be installed. If wear exists on any component, replacement of the entire assembly is necessary. Wear in the chain, gears, or sprockets means a timing lag, which results in poor engine performance.
The timing chain or belt is generally installed with the gears in their correct positions. Before installing a new chain, soak it in oil.
OHC (Overhead Cam) Engines
Some OHC engines use a chain drive; others use a belt drive. Removing the cover on some OHC engines that have timing chains is more difficult, because the cover often fits between the oil pan and the cylinder head. There are special procedures for replacing cam timing components in these engines.
Before a chain repair job, perform a leakage test on non-freewheeling engines to check for bent valves, so that an accurate repair estimate can be made.
OHV (Overhead Valve) Pushrod Engines
On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another. NOTE THIS IS FOR 2WD 4.0

Where are the cam sensors (2) located on my 2005 chevy colorado


I have a 2005 and the things that go bad on it is when the sensor goes off then for the intake then where the butterfly is on the intake gets dirty and needs to be cleaned it is the venturi gets dirty and needs to be cleaned and if it is a cam crank then it is the cam actuator that needs fixed you can tell if you take it off and there a screen missing it is a good sign that it needs be replaced and it is on the left side of the engine you need to understand that if it gives you a code that tells you that it is a sensor that is telling you that what the sensor looks after is bad not the sensor

well not sure exactly why it wont line up use something to turn the crank and cam to appropiate position start sliding crank gear until cam gear is touching then start to push both at same time make sure your crank key and cam pin are bothin place On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another.
