Engine shut off while driving?

Wow! That was unexpected. Chains usually outlast the engine, but 200,000 is a lot.

I don't know if you want this, but here are the directions for replacement. All attached pictures correlate with these directions. Plus, the labor for this job shouldn't exceed 6.0 hours.

TIMING CHAIN REMOVAL AND INSTALLATION
CHAIN AND SPROCKETS-TIMING

REMOVAL
1. Disconnect negative battery (1)cable.
2. Drain cooling system.
3. Remove upper intake manifold.
4. Remove cylinder head covers, crankshaft vibration damper, and timing chain cover.

CAUTION: When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.

5. Align crankshaft sprocket timing mark to mark on oil pump housing (2). The mark on oil pump housing is 60° ATDC of #1 cylinder.

CAUTION: When the timing chain is removed and the cylinder heads are still installed, DO NOT rotate the camshafts or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage.

6. Remove primary timing chain tensioner retainer cap (2) and tensioner (1) from right cylinder head.

7. Disconnect and remove camshaft position sensor (4) from left cylinder head.
8. Remove timing chain guide access plugs (3) from cylinder heads.

NOTE: When camshaft sprocket bolts are removed, the camshafts will rotate in a clockwise direction.

9. Starting with the right camshaft sprocket, remove the sprocket attaching bolts. Remove camshaft damper (1) (if equipped) and sprocket.
10. Remove left side camshaft sprocket attaching bolts and remove sprocket.
11. Remove lower chain guide (7) and tensioner arm (8).
12. Remove the primary timing chain (5).

REMOVAL - CRANKSHAFT SPROCKET

1. Remove primary timing chain.

CAUTION: Use care not to turn crankshaft while removing crankshaft sprocket, as damage to valves and or pistons could occur.

2. Remove crankshaft sprocket by first installing the crankshaft damper bolt. Apply grease or equivalent to damper bolt head and position Special Tools 5048-1(3), 5048-6 (2), and 8539 (1) on sprocket and crankshaft nose. Remove sprocket using care not to rotate the crankshaft.

INSTALLATION
TIMING CHAIN

1. Inspect all sprockets (4, 9, 11) and chain guides (2, 5, 10). Replace if worn.
2. Install crankshaft sprocket.
3. If removed, install right and left side short chain guides (11). Tighten attaching bolts to 28 Nm (250 inch lbs.).
4. Align crankshaft sprocket timing mark to the mark on oil pump housing(3).

NOTE: Lubricate timing chain and guides with engine oil before installation.

5. Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links (1).
6. Lower the primary chain with left side sprocket through the left cylinder head opening.

NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation.

7. Loosely position left side camshaft sprocket over camshaft hub.
8. Align timing (plated) link to the crankshaft sprocket timing mark (3).
9. Position primary chain onto water pump drive sprocket (10).
10. Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain (8) and loosely position over camshaft hub.
11. Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets.
12. Install left side lower chain guide (2) and tensioner arm (5). Tighten attaching bolts to 28 Nm (250 inch lbs.).

NOTE: Inspect O-ring on chain guide access plugs before installing. Replace O-ring as necessary.

13. Install chain guide access plugs to cylinder heads. Tighten plugs to 20 Nm (15 ft. Lbs.).

NOTE: To reset the primary timing chain tensioner, engine oil will first need to be purged from the tensioner.

14. Purge oil from timing chain tensioner using the following procedure:
a. Place the check ball (2) end of tensioner into the shallow end of Special Tool 8186 (3).

B. Using hand pressure, slowly depress tensioner until oil is purged from tensioner.
15. Reset timing chain tensioner using the following procedure: a. Position cylinder plunger (4) into the deeper end of Special Tool 8186 (3). B. Apply a downward force until tensioner is reset.

NOTE: If oil was not first purged from the tensioner, use slight finger pressure to assist the center arm pin of Special Tool 8186 to unseat the tensioner's check ball.

CAUTION: Ensure the tensioner is properly reset. The tensioner body (4) must bottom against the top edge of Special Tool 8186 (3). Failure to properly perform the resetting procedure may cause tensioner jamming.

NOTE: Inspect the tensioner O-ring (2) for nicks or cuts and make sure the snap ring (1) is correctly installed, replace as necessary.

16. Install the reset chain tensioner (1) into the right cylinder head.
17. Position tensioner retaining plate (2) and tighten bolts (1) to 12 Nm (105 inch lbs.).

18. Starting at the right cylinder bank, first position the camshaft damper (1) (if equipped) on camshaft hub, then insert a 3/8" square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and tighten to 28 Nm (250 inch lbs.).
19. Turn the left side camshaft by inserting a 3/8" square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed. Tighten sprocket bolts to 28 Nm (250 inch lbs.).
20. Rotate engine slightly clockwise to remove timing chain slack, if necessary.

21. Activate the timing chain tensioner by using a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly. Then release the tensioner arm. Verify the tensioner is activated (extends).

22. Install camshaft position sensor (2) and connect electrical connector.
23. Install the timing chain cover, crankshaft vibration damper, and cylinder head covers.
24. Install upper intake manifold.

NOTE: After installation of a reset tensioner, engine noise will occur after initial start-up. This noise will normally disappear within 5-10 seconds.

25. Fill cooling system.

26. Connect negative battery (1) cable.

INSTALLATION - CRANKSHAFT SPROCKET

1. Install crankshaft sprocket using Special Tools 6780-1(1) and 8179 (2) until sprocket bottoms against crankshaft step flange. Use care not to rotate crankshaft.

2. Verify that crankshaft sprocket is installed to proper depth by measuring from sprocket outer face to end of crankshaft. Measurement should read: 39.05 ± 0.50 mm (1.5374 ± 0.020 inch).
3. Install primary timing chain.

Let me know how everything works out for you. I have to be honest, I'm not sure why the starter engaged when you did it manually, but not with the switch. That seems odd.

This is real common after the battery has been disconnected for some other service. The Engine Computer has to relearn "minimum throttle" before it will know when it must be in control of idle speed. Until then, the engine may not start unless you hold the accelerator pedal down 1/4". You won't get the nice idle flare-up to 1,500 rpm's at start-up, and it will tend to stall at stop signs.

To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the pedals.

Hello and thank you for using 2CarPros. Can you give us the codes so we can see what the computer is trying to tell you? If you are having running to lean codes then I would recommend your mechanic drive the vehicle with a fuel pressure gauge and have them duplicate the concern to see if you are losing pressure.

If you are having running too rich codes then you maybe overfilling the tank? Do you stop at the click when filling or give it a few more clicks in there to top off? If that is the case then you most likely saturated the charcoal canister with raw fuel. When the evap starts purging then it is sucking in the extra fuel causing your vehicle to flood and stall.

Please get back to us with the codes to see if it is a fuel issue or you could have some electrical issue causing the whole thing to shut down especially if the accessories are shutting down also.

Are you able to restart after it stalled?
Is there any indicators showing on dash prior to the stalling?

Symptoms indicates a possible fault with the EVAP system which would normally trigger trouble codes. Get a scan done to check if any trouble codes are stored.

It could be clogged EVAP lines, kinked hoses or faulty solenoids.

If the rear differential was worked on, it could have affected the system if the lines are kinked or bent too much.

Check the areas around the fuel tank for any interference to EVAP lines.

When no trouble codes are present, it should not be a fault with solenoids or electrical components. The lines are for pressure release and fumes control and is usually dry. Cleaners might not work as the lines are from front of vehicle to rear so it could be quite long.

If the lines wre slightly kinked or clogged, it would take some time before the clogging becomes to bad till pressure is not being released while refilling.

P1521-INCORRECT ENGINE OIL TYPE

When Monitored:

Engine Running.

Set Condition:

Using the oil pressure, oil temperature and other vital engine inputs the PCM can determine the engine oil viscosity. Incorrect viscosity will effect the operation of the MDS by delaying cylinder activation.

The following conditions must be checked.
†OEM recommended oil viscosity is being used.
†Customer is following the oil change schedule.
†Check the engine oil for contamination. (I.E, fuel and/or engine coolant)
†Internal engine condition that may effect oil pressure.

Were any of the above conditions found?

Yes
Repair as necessary.
Perform POWERTRAIN VERIFICATION TEST.

No
Change the engine oil using the correct oil viscosity.
Perform POWERTRAIN VERIFICATION TEST.

Have you checked the wiring under the power distribution box under the hood? The harness there is known for poor connections causing these lights to come on. An accident could have caused a loose connection.
