Install water pump new timing belt ran for three hours now wont start on 2002 neon

You're not giving much to go on. Is it a 2.0L or a 2.4L?
You say it won't start. Does it turn over and not fire, or does it just sit there and do nothing when you turn the key?

Both engines require you to remove the timing belt in order to change the water pump. The 2.0L is definitely an interference engine, and I'm not sure about the 2.4L. But if the timing belt was not re-installed properly, it will result in a no-start condition since the valves will not be in sync with the pistons and spark. Best case scenario you correct the issue and are good to go. Worst case scenario is that if the belt is out too far, you bent valves and have to service the head(s).

The timing belt could have been loose, or the tensioner not set correctly. It sounds as if your timing belt has slipped.

Three things to check. Spark, fuel and timing.
Take plug. Out and check good spark, needs to be earth to engine block or car. Is the fuel pump working. Timing could be out usually 180 degrees. if you worked on car recently to do timing chain/belt.
There sensor all over cars the most likely is the crankshaft sensor. Lug in computer and get error messages. Good luck

If you start a Dodge Neon three times with an unchipped key the car will lock down, you have to contact a Dodge dealer to have them "unlock" the car. I found this out when I first bought mine, luckily I didn't start it three times with the blank key so I couldn't tell you how much it will cost a dealer to repair the problem, as I am assuming they just reset the computer. Or you could attach a diagnostic computer to the car, it will usually allow you to reset any issues which may work as well.

Yes your timing belt turns the pully on the water pump

Sounds like timing belt not on correctly. Check timing marks are aligned correctly when installing timing belt. This vehicle should have 2-3 marks to be aligned when installing belt.marks should be on cam gear/ crankshaft gear and intermediate shaft if engine is equipped with it.

This is not an easy task and you will find it takes about 6-8 hours if you have all the needed parts ready to install if you need them. Don't expect to just go to the local parts place and obtain some of these parts. There are several dealer only parts.

Before you start this job:
1. Inspect the upper and lower torque struts that hold the motor on the passenger side. Order them ahead of time if you see they are damaged. Make sure the local parts store has them in stock if you are not sure of their integrity. You can tell if they are bad when you remove them; they just fall apart or you can see the split neoprene.
2. Inspect your accessory belts and the serpentine tensioner pulley prior to beginning the work. Order the belts (If you have over 75,000 miles on the vehicle, you will need the new accessory belts.) or know where you can purchase them locally.
3. Make sure you can get a new timing belt tensioner unit locally at your Mopar Dealer. If you have a mechanical timing belt tensioner, you are warned by a Dodge technical bulletin to replace it with a hydraulic unit.
4. Order a water pump and replace it while replacing the timing belt.
5. Of course, purchase a timing belt, lol...


First, it was necessary to remove the passenger side tire and the splash guard behind the tire in the wheel well. The next items to remove were the accessories belts (ac, alternator, etc.) which included the serpentine belt. The crankshaft damper had to be removed with a three-arm puller tool and a small insert that protects the crankshaft threads. Remove the power steering pump by just setting it off to the side after removing the bolts. You don't have to undo the hoses; just lay it over to the side.

Using a floor jack, you hold the engine in place while you remove the lower torque arms. Inspect the upper and lower torque arms carefully. I would at least inspect these torque arms carefully for broken neoprene prior to beginning the timing belt change.


Next, you must remove the serpentine tensioner plate which has three bolts. This was a totally unexpected cost for my timing belt replacement when I tried to purchase only the plastic tensioner pulley and was informed that the item was not a replacement part; you had to go to Dodge and purchase an entire plate (with a redesigned "hydraulic" tensioner for the serpentine belt tensioner). go to a local salvage yard and obtained a fairly new tensioner pulley for about $5.00; the old plastic pulley will be completely worn away. A new serpentine tensioner plate with the integral tensioner is $429 at Dodge.


You can now remove the front timing cover. Make sure to align the camshaft and crankshaft timing marks before removing the timing belt. The camshaft pulley has a mark that needs to align with the mark on the head above the pulley. The crankshaft sprocket should line up at the same time with its mark at the top of the oil pump assembly. If you accidentally move the camshaft in some manner, after you remove the timing belt, you can damage the pistons or valves.

Next, to loosen the old timing belt, you need to look at the tensioner. Insert an 8 mm Allen wrench into the hexagon opening located on the front of the belt tensioner pulley. Rotate the pulley counterclockwise until it contacts the stop. While holding tensioner pulley against stop, insert a 1/8" or 3 mm diameter pin or Allen wrench through the hole located to the left of the hex opening. While pushing pin into hole, allow the tensioner pulley to rotate back. Almost immediately, the pin should engage the locking hole to prevent further movement of the pulley. I was totally surprised by what happened when I tried to purchase a new timing belt tensioner pulley as my pulley was worn quite badly. I received the wrong part to replace the tensioner pulley three times at three different parts stores. It took about an hour to discover that there was a problem with the old "mechanical" timing belt tensioners. It is not just recommended that you change the tensioner; you must replace the timing belt tensioner plate and all if you have the older mechanical tensioner. This is a technical bulletin from Mopar that says there have been several "explosions" of the mechanical units with engine replacements needed; the tensioner actually blew a hole in the engine block. Of course, this is not a "free replacement" due to a manufacturing problem; you must purchase this item. Some of the latter models of the 2000 Neon have had the hydraulic units installed and all you need to purchase is the tensioner pulley which costs about $30. You can tell if you have the mechanical one when you actually get into and remove the timing belt; the mechanical unit has four pronounced legs, while the hydraulic unit is more of a plate (even though the holes align for both units). You must replace the back timing belt cover with a new tensioner installation (and it comes with the kit). In the earlier neon model required a complete plate, hydraulic unit and tensioner pulley replacement. And, of course, it a dealer item only with a cost of $469.

Before you begin your job of timing belt replacement, find out if you own an earlier 2000 and also locate a dealer with the unit in stock. You honestly should install the hydraulic unit as the technical bulletin explains the damage from an "explosion".


While you are in there, you should replace the water pump. If you read all the bulletins and people's posts about this item going bad just after they finished the timing belt, you really should just purchase the water pump and make sure it has the seal in the kit (some did not include the water pump seal.). The water pump was only $40. If you have to replace it, you see all the trouble you must go through again to get it out of the timing belt area. The water pump is driven by the timing belt.
The oil pump is also driven by the timing belt; however, there are not many failures of the oil pumps.

Now you may start to put the timing belt into place. If you have gotten the timing just a tiny bit off, you can follow the procedure as below. It is hard to explain in words only without pictures; however, I will try to do so.


Set crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing, then back off to 3 notches before TDC, that is clockwise three teeth.

Use a large wrench and the crankshaft nut to carefully adjust the timing. This is to allow for belt installation later.


Set camshaft to TDC by aligning mark on sprocket with the arrow on the rear of timing belt cover. Move crankshaft to 1/2 mark before TDC for belt installation.


Install timing belt.
Starting at the crankshaft, go around the water pump sprocket and then around the camshaft sprocket.
Move crankshaft sprocket to TDC to take up belt slack.
Remove the pin or 1/8" or 3 mm Allen wrench from belt tensioner.
Rotate crankshaft 2 revolutions and check the alignment of the timing marks.


Install front timing belt cover. Install engine mount bracket. Install right engine mount to engine mount bracket through bolt. Remove jack from under engine. Install upper torque strut. Install power steering pump assembly. Raise vehicle and install lower torque strut. Install crankshaft damper using M12-1.75 x 150 mm bolt, washer, thrust bearing and nut from Special Tool 6792. Install crankshaft damper bolt and tighten to 142 Nm (100 ft. lbs.). Install accessory drive belts. Install right inner splash shield.
Lower vehicle and perform camshaft and crankshaft timing relearn procedure as follows: Connect the DRB scan tool to the data link (diagnostic) connector. This connector is located in the passenger compartment; at the lower edge of instrument panel; near the steering column. Turn the ignition switch on and access the "miscellaneous" screen. Select "re-learn cam/crank" option and follow directions on DRB screen.
It is not a fun job unless you enjoy some very hard work and have a few specialized tools. The scan tool was purchased at Sears (I hope I can say a specific name. You can purchase the scan tool at a parts store or off the web as well.). The special tool is a three-arm puller. The other special tool is to protect the crankshaft threads. Hope this helps!!! and thank you for using FIxya

probably water pump, and it is run off the timing belt, so that probably broke when the pump died. if the belt broke the car wolnt start.
