There is a special tool you need to purchase . It connects on your front motor mount located on top by radiator.. This is what is called the dog bone in the industry . The specialty tool is put in the place of dog bone mount and is adjustable whith vehicle placed in neutral... The tool pulls the motor towards the radiator giving you complete easy access and complete visibility for what you are trying to achieve

Im trying to change the ignition control module in my 1997 astrovan but i cant get it out

does it have the 6 cylinder engine with the 3 coil packs on top? If so, remove spark plug wires from coil packs, remove 2 screws that hold each pack down, remove coil packs (but remember to put everything aback as it was when finished! includes where wires were on coils), remove screw that holds the connector to the module, install new module to connector and reverse to install.

I need a diagram for a spark plug wires on a 99'

start with the serpentine belt side of the car (passenger) the first plug hole will be #1 then 2-4 as you work your way to the drivers side as Im guessing this is a 4 cylinder. The coil pack on the top of the engine has all the plug wires coming out of it and should be numbered 1-4 go accordingly from there.

Engine light on

They are still looking for a cause because it isnt misfiring right now or because they cant find the cause of the stored misfire codes ?
If it is misfiring right now and they cant figure it out then perhaps you should find new mechanics !
I have seen a lot of bad coils on the PT.
Misfire is usually caused by spark plug wires first, spark plugs 2nd, and coil third.
If it isnt misfiring now, spray down the wires with water. If it misfires after that replace the spark plug wires and spark plugs and try again.
If it still misfires then the problem will likely be the coil.

Changing the rod bearings won't have any effect on the trucks ability to start or not start. Since you said you did not take motor out or take off head, I'm also going to assume you didn't mess with the timing belt/chain. Also I'm assuming the engine will crank, just not start. If not try turning the engine by hand, If it dosen't move something got messed up when the bearings were replaced. If the engine cranks, pull any spark plug wire off the plug insert a screwdriver, hold about 1/4 inch to 1/2 inch from the engine block and crank the engine (hold onto the plastic handle) there should be a spark. If there is a spark remove a plug and check the distance between the electrode and the terminal. If no spark do the same thing with the coil wire. If coil wire sparks you have a problem between the coil wire and the individual plug wires (distributor, cap rotor, etc). If coil does not spark you have a problem with the primary side of the ignition circuit (ignition switch, wiring, primary windings of the coil, etc). If the engine still does not run try spraying (just a little) starting fluid or choke cleaner into the intake (past the air filter). If engine starts you have a fuel problem. You would need to check out you carburetor, fuel pump, etc. If after spraying starting fluid into the intake, the engine still dosen't start, remove any duct work and filter going into the intake. (this will eliminate any restriction in the intake). Try starting, if still dosen't start, remove the exhaust pipe from the exhaust manifold and try starting, this will eliminate any exhaust restriction. If engine still dosn't start you are going to have to do compression tests on the engine, and or cylinder leakage tests, and or vacuum tests on the engine. If you get to the point where you have to try these tests you are looking at something wrong internally with the engine (timing jumped out of adjustment, no compression, etc) Sorry I couldn't give you a simple straight forward answer but I hope this gets you up and running.

Cant locate spark plugs

If it is a 4 cylinder engine you should have 4 black thick wires going into four points in line, on a V6 engine there will be 6 of them, should be easy to find them now.

Stays runing from point a to point b after that it wont start 2 h

I hate to tell you this but they are not fun to remove. Do not try this when the car is hot you will be burnt by the exhaust if you do! You have to reach up the backside of the engine and most of the work can only be done using one hand. Make sure you number your wires so you can put them back in the right place. If you mess up the factory coils have numbers on the most of the time and number one plug will be on left side, first plug, if you are facing the car. It’s hard to tell which wire you have when it goes behind the engine. You can have the coil checked at Autozone or Advance they should be able to help you with that! If for some reason they can’t post again and I can send the information needed to check them if you think you can do it yourself.

See Figure 1
1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle.
3. Detach the assembly electrical connectors.
4. Tag and disconnect the spark plug wires.
5. Unfasten the three ignition coil assembly-to-block bolts, then remove the assembly from the engine.
Fig. 1: Exploded view of the ignition coil assembly - 2.2L (VIN 4) engine shown
To install:
6. Position the ignition coil assembly to the engine. Install the mounting bolts, then tighten to 15-22 ft. lbs. (20-30 Nm).
7. Connect the spark plug wires to the proper coils, as tagged during removal.
8. Attach the coil electrical connectors.
9. Carefully lower the vehicle, then connect the negative battery cable.

A 2.2 and a 2.0 are basically the same engine.

Wont Start

Have another look at your plug wires, and make sure that you have them in the right order. As you probably know, if the firing order is wrong, you can have problems. That is somewhere for you to start, anyway.
