Engine cranks but will not start

Hi and thanks for using 2CarPros.com.

I have to be honest, many things can cause a no start. However, the idea that it is cranking faster or sounds different concerns me. That is usually an indication of a timing issue which could be the result of a broken timing belt. The first thing I would do is check engine compression. If you want to do it yourself, here are directions:

https://www.2carpros.com/articles/how-to-test-engine-compression

If you find low compression, next I would check the timing belt. Here are directions for checking it. This will require some time. NOTE: You listed an engine size that doesn't exist. The attached info is for a 4.7L. If that is incorrect, let me know.

PLEASE NOTE: If the timing belt has failed and broken, this engine is what is known as an interference engine. That means major internal engine damage can result in the event of belt failure.

TESTING AND INSPECTION
INSPECTION
INSPECT TIMING BELT.
NOTICE:
Do not bend, twist or turn the timing belt inside out.
Do not allow the timing belt to come into contact wit oil, water or steam.
Do not utilize timing belt tension when installing or removing the mount bolt of the camshaft timing pulley.
If there are any defects, as shown in the illustrations, check these points:
Premature parting
Check for proper installation.
Check the timing cover gasket for damage and proper installation.
If the belt teeth are cracked or damaged, check to see if either camshaft is locked.
If there is noticeable wear or cracks on the belt face, check to see if there are nicks on the side of the idler pulley lock and water pump.
If there is wear or damage on only one side of the belt, check the belt guide and the alignment of each pulley.
If there is noticeable wear on the belt teeth, check timing cover for damage and for foreign material on the pulley teeth. If necessary, replace the timing belt.
INSPECT IDLER PULLEYS.
Visually check the seal portion of the idler pulley for oil leakage. If leakage is found, replace the idler pulley.
Check that the idler pulley turns smoothly. If necessary, replace the idler pulley.
INSPECT TIMING BELT TENSIONER.
Visually check the seal portion of the tensioner for oil leakage.
HINT: If there is only the faintest trace of oil on the seal on the push rod side, the tensioner is all right.
If leakage is found, replace the tensioner.
Hold the tensioner with both hands and push the push rod strongly as shown to check that it doesn't move. If the push rod moves, replace the tensioner.
NOTICE: Never hold the tensioner push rod facing downward.
Measure the protrusion of the push rod from the housing end.
Protrusion: 10.5 -11.5 mm (0.413 - 0.453 inch)
If the protrusion is not as specified, replace the tensioner.

If you find the belt has jumped or broken, here are the directions for removal and replacement. Please keep in mind, I'm not sure what you are able to do, but I figured I would include the directions if you want them. Pictures 6 through 30 are for removal.

_____________________________________________

As you can see, it is not an easy job. Again, this is an interference engine. If the belt broke, the cylinder heads need removed to check for damage to the valves and the pistons. In most cases, it is cheaper to find a good used engine and replace the existing one.

I will keep my fingers crossed that is not the issue. Please update me on what you find or if you have other questions.

Take care and good luck,
Joe

Hi again. Sorry about that. I checked my resources and that was the only engine which was indicated. Actually, I have two very good resources and neither show that engine. I am going to ask for help from one of the other techs who is better with diesel.

As far as a compression test, it works the same other than rather than removing spark plugs, you will remove glow plugs or injectors. The process is the same. Let me see if I can get more help on this one.

Let see if it is a fuel or engine problem. They make diesel engine starting fluid, try using a can into the intake to see if you can get the engine to run which will help narrow things down.

Please let us know what happens.

Cheers, Ken
