I cannot get timing to 5 degrees . Timing is a15 degress and run great .Timing chain is timed to cam properly. If i set timing at 5 degress engine runs rough and dies . I did not short out terminal T .because I dont know what that is . Could anyone help with this problem?

When you are setting timing you are setting top dead center and bottom dead center. Once established based on the marks on the crank and cam you adjust top dead and BDC by degrees in ADVANCED timing or behind/retarded timing by degrees by counting links. Each link used to be 5 degrees. Check repair manual on link values! they change with each engine and maker.
It starts up easy and idles good? And timing is at 10 BTDC? Sounds like you got it right then. I would check the fuel pressure at the fuel rail first. If fuel pressure is correct, maybe the throttle position sensor is bad?
Do you have vacuum advance on the distributor, or is it controlled by the ecu? If a vacuum advance device, maybe that is the problem. Beyond that, I don't know.
place no 1 piston at TDC compression stroke. There are procedures for the timing of the balance shafts but if it is only the timing chain I will go to that
Align uniquely coloured chain link with intake camshaft sprocket timing mark-- INT--. ( this will be pointing at the 2 o'clock position)
install timing chain and sprocket as an assembly
align first matching coloured chain link crankshaft timing mark (5 o'clock position)
align the second matching coloured chain link with exhaust cam shaft timing mark--EXH ( at the 11 o'clock position
There is a special procedure to reset the balance tensioner and it is different to the timing chain procedure.
To reset cam shaft timing chain tensioner push piston fully and turn clockwise until locked
Once the tensioner has been compressed ensure the distance from end to end is 2.83 inches . If not repeat the resetting process
vehicles 30.000 miles the tensioner is released when the engine is first started . In vehicles over 30.000 miles manually release tensioner by tapping the plunger
Note cam shaft and crank shaft sprockets bolts MUST only be used once. If you want details on the balancer chain procedure then make a comment in the box
use tension wrench and a degree gauge
cam bolts are tensioned to 63 ft lbs + 30 degrees
crank shaft pulley is tensioned to 74 ft lbs + 75 degrees
It appears that you got it right but to be sure the check is on the timing chain there are 3 black links If you have it right then the black links will line up with the marks. If not then re adjust the gear that is not correct.- ensure that you have the ignition timing right as you may be 180 degrees out
Hello, this code indicates a problem with the cam timing. in most cases the timing chain is the problem. the engine control module can no longer adjust cam timing to the proper spec while running. this normally requires the timing chain to be replaced. this is covered under the 5 year 100,000 mile warranty thru GM
Did you get the timing set correctly when you reattached the cam to the timing chain? It sounds like you didn't have the #1 Top dead center or the cams were in the wrong position when you reset the timing chain. The cam shaft and Crank will actually look like they are set correctly two times. Once when it is in time and once when it is out of time 180 degrees. If you are more than 5 degree out of time or more than 5 degrees from the point where it is 180 degrees out of time the engine normally won't fire at all. The easiest way to check and verify this is to do compression checks on the cylinders, you will find you have little or no compression on several cylinders if this is the case. To correct it remove the timing chain and set the crank to #1 Top Dead center. Then go to the head that is on the #1 side, line the cam up so that both valves are closed for the number 1 and line that mark up. You have to find the firing order to make sure the intake is open getting ready to close for the next cylinder that going to fire and the exhaust valve is closed, then make teh final adjustment to line that cams timing mark up then replace the timing chain. This should get everything roughly within 5 degrees of zero and should get the motor so it will start.
Sounds like the timing is off or something wasn't synch'd up correctly during the rebuild. Check the timing and make sure the vacuum lines are connected correctly, especially the vacuum advance which advances your timing when the engine RPM's are increased. Start your timing at 5 degrees before top dead center, the 5 mark on your timing marks, this is the most common baseline setting for timing. If you have to set it advanced beyond 10 degree or retarded beyond 0 then your timing chain was not aligned correctly between the Pistons and the Valves or cam shaft.
REMOVAL & INSTALLATION NOTE: The manufacturer recommends that the entire powertrain be removed from the vehicle before removing the cylinder heads.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
Drain the cooling system.
Properly relieve the fuel system pressure.
Remove or disconnect the following:
Negative battery cable
Powertrain assembly
Intake manifold
Cam covers
Harmonic balancer
Timing chain front cover
Oil pump
WARNING Align all timing marks before performing the next step.
Chain tensioner from the timing chain
Cam sprockets
NOTE: The timing chain remains in the chain case.
Timing chain guides, access for the retaining screws is through the plugs at the front of the cylinder head
Water crossover
Exhaust manifold
Cylinder head bolts by reversing the torque sequence
Cylinder head and discard the gasket
WARNING With the camshafts remaining in the cylinder head some valves will be open at all times. Do not rest the cylinder head on a flat service with the cylinder face down, or valve damage will result.
NOTE: Clean all gasket mating surfaces. Clean the head bolt holes in the crankcase. WARNING Be careful when cleaning aluminum gasket surfaces to prevent damage to the sealing surfaces.
Check the cylinder head for warpage; it must be less than 0.002 in. (0.05mm). If the cylinder head was resurfaced, the dimension between the combustion chamber gauge pad and the deck surface must be at least 10.5mm.
To install:NOTE: Refer to Section 1 of this manual for the cylinder head torque sequence illustration. The illustration is located after the Torque Specification Chart.
Install or connect the following:
New cylinder head gasket
Cylinder head, lubricate the bolts with engine oil
Torque the M11 bolts, in sequence, as follows:
Step 1: 22 ft. lbs. (30 Nm).
Step 2: Turn an additional 60 degrees.
Step 3: Turn an additional 60 degrees (total 180 degrees).
Torque the M6 bolts to 106 inch lbs. (12 Nm).
Set the camshaft timing
Camshaft guide bolt access hole plugs in the cylinder heads. The plugs should be seated and snug
Install or connect the following:
Intake cam covers
Oil pump
Timing chain front cover
Harmonic balancer
Cam sprockets
Chain tensioner to the timing chain
Timing chain guides
Intake manifold
Water crossover
Exhaust manifold. Torque the nuts to 22 ft. lbs. (30 Nm) or the bolts to 18 ft. lbs. (25 Nm).
Powertrain assembly
Negative battery cable

google Dodge 2.7 timing chain............select images........... the 2nd and 3rd images that come up are drawings of the timing chain assembly. Hit either one of these , and you will get full instructions for doing the job. Note ... by my eye it does not look like the timing marks on the cam pullys are exactly at the top. Slightly off to one side.
