Neon 2005 sxt no enciende

#1
Buen dia amigos mi neon 2005 trono la banda del tiempo duro semanas parado ya se le arreglo y cambiaron valvulas y todo aceite todo empaques y lo arrancamos normal se empezo a escuchar como si tuviera poca fuerza y como carro de diésel duro 10 minutos aproximadamente prendido y abri la puerta del conductor y se apago sin hacer ruidos feos ni nada asi ni cuenta me di ya le cambiamos sensor de cigueñal del arbol de levas checamos el tiempo y todo y sigue sin encender y no marca codigos ayuda cabe mencionar que el mecanico dice averlo prendido con la alarma puesta pero no marca bloqueo tampoco

Hola, comparto indicaciones para poner a tiempo el Neon Sxt 2.0L 2005, por si te sirve
2000-2005 NEON
This engine is classified as an Interference engine. If the timing belt breaks or jumps timing, a piston may contact an open valve. Piston to valve contact may cause damage to the valve, piston and other engine components. In some cases valve to valve contact may be experienced when the timing belt breaks or jumps timing. To avoid belt breakage, replace the timing belt as recommended by the vehicle manufacturer timing belt replacement interval.
With the timing belt removed, avoid turning the camshaft or crankshaft. If movement is required, exercise extreme caution to avoid valve damage caused by piston contact.
1.Disconnect and isolate the battery ground cable.
2.Remove the engine accessory drive belts.
3.Loosen the righthand front wheel lug nuts.
4.Raise and safely support the vehicle with jack stands.
5.Remove the righthand front wheel and tire assembly.
6.Remove the righthand inner splash shield.
7.Remove the crankshaft damper retaining bolt, Figs. 1 and 2.
8.Remove the crankshaft damper using DaimlerChrysler tool Nos. 1026 and 6827-A, or equivalents.
9.Remove the bolts attaching the lower torque strut to crossmember and strut bracket, then the lower torque strut.
10.Support the engine with a suitable jack and wooden block placed under the oil pan.
11.Remove the upper torque strut to shock tower and engine mount bracket bolts, then the upper torque strut and right engine mount through bolts.
12.Remove the power steering pump and position aside with hoses attached.
13.Remove the righthand engine mount bracket from the engine.
14.Remove the timing belt outer cover.
15.Disconnect spark plug cables from spark plugs, then remove the spark plugs. Tag the spark plug cables and spark plugs so they can be installed at the same locations.
16.Align the crankshaft and camshaft sprocket timing marks before removing the timing belt by rotating the crankshaft. Fig. 3.
17.On models equipped with a hydraulic timing belt tensioner, loosen the tensioner mounting bolts, but do not loosen, remove or tighten the tensioner pivot bolt.
18.On 2000 models equipped with a mechanical timing belt tensioner, proceed as follows:
a.Do not separate the tensioner pulley from its mounting bracket.
b.Insert an 8 mm hex wrench into the tensioner, Fig. 4.
c.Insert the long end of a 1/8 inch or 3 mm hex wrench into the pin hole on the front of the tensioner.
d.Rotate the tensioner counterclockwise with the hex wrench while pushing in lightly on the 1/8 inch or 3 mm hex wrench until it slides into the locking hole.
19.On 2002-05 models equipped with a mechanical timing belt tensioner, proceed as follows:
a.Loosen the timing belt tensioner lock nut.
b.Insert an 6 mm hex wrench into the tensioner top plate, Fig. 5.
c.Rotate the tensioner plate clockwise to relieve timing belt tension.
20.On all models, remove the timing belt.
21.On models equipped with a hydraulic timing belt tensioner, proceed as follows:
a.Remove the tensioner retaining bolts, then the tensioner.
b.Position the tensioner in a soft-jawed vise. Place the tensioner in the vise the same way as it is installed on the engine. This ensures proper pin orientation for easier installation.
c.Slowly compress the tensioner rod.
d.After the tensioner rod has been compressed, insert a 5/64 inch hex wrench through the tensioner body hole to retain the plunger in position, Fig. 6.
e.Remove the tensioner from the vise.
22.On all models, set the crankshaft sprocket to TDC by aligning the sprocket mark with the oil pump housing mark, then back the crankshaft sprocket off TDC by three notches, Fig. 7.
23.Set the camshaft sprocket to TDC by aligning the sprocket mark with the mark on the rear timing belt cover, Fig. 8.
24.Move the crankshaft sprocket to 1/2 notch before TDC, Fig. 9.
25.Install the timing belt over the crankshaft sprocket, water pump sprocket, camshaft sprocket and under the tensioner pulley.
26.Move the crankshaft sprocket 1/2 notch to the TDC position.
27.On models equipped with a hydraulic timing belt tensioner, proceed as follows:
a.Install the timing belt tensioner, but do not tighten the attaching screws.
b.Apply approximately 21 ft. lbs., of torque using a suitable torque wrench to the belt tensioner pulley, Fig. 10.
c.With torque being applied to the tensioner pulley, move the tensioner against the tensioner pulley bracket. Torque the tensioner retaining screws to 23 ft. lbs.
d.Remove the hex wrench from the tensioner body and plunger holes. Proper pretension is proven when the hex wrench can be installed and removed from the tensioner body hole.
28.On 2000-01 models equipped with a mechanical timing belt tensioner, remove the pin or hex wrench from the tensioner.
29.On 2002-05 models equipped with a mechanical timing belt tensioner, proceed as follows:
a.Insert a 6 mm hex wrench into hexagon opening located on top plate of belt tensioner pulley.
b.Rotate the top plate counterclockwise, the tensioner pulley will move against timing belt and the tensioner and setting notch will eventually start to move clockwise.
c.Watching the movement of setting notch, continue rotating the top plate counterclockwise until setting notch is aligned with spring tang, Fig. 11.
d.Torque tensioner lock bolt to 22 ft. lbs., while using the 6 mm hex wrench to prevent top plate from moving.
30.On all models, rotate the crankshaft two turns clockwise. Ensure the crankshaft and camshaft sprocket timing marks are aligned, Fig. 3. If not, the timing belt will have to be removed and installed again.
31.On 2002-05 models, ensure spring tang is within the tensioner tolerance window, Fig. 12. If spring tang is not within tolerance window, repeat steps 29 through 31.
32.On all models, install the timing belt cover. Torque the attaching screws to 105 inch lbs.
33.Install the engine mount bracket. Tighten the attaching bolts to 45 ft. lbs.
34.Install the right engine mount through bolt. Torque the right engine mount through bolt to 87 ft. lbs.
35.Install the upper torque strut.
36.Install the power steering pump.
37.Install the lower torque strut.
38.Remove the jack and wooden block from under the oil pan.
39.Perform the torque strut adjustment as follows:
a.Loosen the upper and lower torque strut attaching bolts.
b.Position a suitable jack and wooden block under the engine oil pan.
c.Carefully apply upward force, allowing the upper engine to rotate rearward until the distance between the center of the rear most attaching stud on the engine mounting bracket (A) and the center hole for the washer hose clip on the shock tower bracket (B) is 4.70 inches (119 mm), Fig. 13. Hold the engine in this position.
d.With engine held in position, torque the upper and lower torque strut bolts to 87 ft. lbs.
e.After the upper and lower torque strut bolts have been tightened, remove the jack and wooden block from under the engine oil pan.
40.Install the crankshaft damper using DaimlerChrysler tool No. 6792, or equivalent.
41.Install the crankshaft damper retaining bolt, then torque to 100 ft. lbs.
42.Install the alternator and A/C compressor drive belt. Refer to "Accessory Drive Belt Tension" for proper belt tension.
43.Install the power steering pump drive belt. Refer to "Accessory Drive Belt Tension" for proper belt tension.
44.Install the inner splash shield, then the wheel and tire assembly.
45.Remove the jack stands and lower the vehicle, then tighten the lug nuts.
46.Connect the battery ground cable.
47.The DaimlerChrysler DRB Scan Tool or another suitable scan tool may be required to perform the camshaft and crankshaft relearn position procedure. Follow the tool manufacturer's instructions.
