Changing the timing belt as a precaution but now created an issue. Before removing the old belt rotated engine to line up all marks at the identified locations. Proceeded to replace the belt verifying the same Camshaft and Crankshaft marks were aligned. Engine starts but appears as if the timing is to far advance (when initially cranking) and the idle will hunt. If you raise the engine speed it feels like the ignition is breaking down. We replaced the sparkplugs and rechecked the timing belt alignment 5 times and still this issue cannot get cleared.
Does the Engine Control Module lock into a limp mode until it is reset? During the initial repair the engine was cranked over with the Mass airflow sensor and the Cranksensor disconnected.

Installation (Eclipse & Galant) 1. Place auto-tensioner in soft-jawed vise to SLOWLY compress the push rod. If there is a plug at the base of the auto-tensioner body, place flat washer around plug so it will not contact vise jaw. 2. Slowly compress auto-tensioner push rod until holes in push rod and auto-tensioner housing are aligned. Insert a locking pin into the alignment holes. Install auto-tensioner on engine. 3. Ensure all timing marks are still aligned. See Fig. 2. Install timing belt on crankshaft sprocket, idler pulley, left bank camshaft sprocket, water pump pulley, right bank camshaft sprocket, and tensioner pulley. Take all slack out of timing belt. 4. Loosen the tensioner pulley center bolt. Using Tensioner Pulley Socket Wrench (MD998767), rotate tensioner pulley against timing belt. Temporarily tighten tensioner pulley center bolt. Using Crankshaft Pulley Spacer (MD998769), turn crankshaft 1/4 turn counterclockwise. Turn crankshaft 1/4 turn clockwise. Ensure all timing belt marks are still aligned. 5. For 1999-00 models, loosen tensioner pulley center bolt. Position tensioner pin holes at BOTTOM of tensioner. Install Tensioner Pulley Socket Wrench (MD998767) on tensioner pulley. See Fig. 6. Use a torque wrench to apply 39 INCH lbs. (4.4 N.m) of torque (counterclockwise direction) to tensioner pulley. Tighten tensioner center bolt to specification while holding tensioner stationary. See TORQUE SPECIFICATIONS. 6. For 2001 and later models, loosen tensioner pulley center bolt. Position tensioner pin holes at TOP of tensioner. Install Tensioner Pulley Socket Wrench (MD998767) on tensioner pulley. See Fig. 7. Use a torque wrench to apply 39 INCH lbs. (4.4 N.m) of torque (clockwise direction) to tensioner pulley. Tighten tensioner center bolt to specification while holding tensioner stationary. See TORQUE SPECIFICATIONS. 7. On all models, remove locking pin from auto-tensioner. Turn crankshaft 2 revolutions clockwise and align all timing marks. DO NOT rotate counterclockwise. 8. Wait for at least 5 minutes, then check auto-tensioner push rod protrusion. To check push rod protrusion, measure clearance between body of auto-tensioner and bottom of tensioner pulley bracket arm. Clearance should be 0.15-0.20" (3.8-5.0 mm). If protrusion is not correct, repeat timing belt tensioning procedure. 9. Install engine support bracket on engine block. Tighten top bolt first, then working in a counterclockwise direction, tighten the remaining bolts. See Fig. 8. Install timing belt covers. Install crankshaft pulley. Apply engine oil to crankshaft pulley bolt, then tighten bolt to specification. See TORQUE SPECIFICATIONS. 10. To install remaining components, reverse removal procedure. Adjust drive belts to proper tension. CAUTION: Never compress the auto-tensioner too fast, or the push rod will be damaged. WARNING: Right bank camshaft can turn easily due to applied spring force, so keep fingers out of the way.

I'm considering buying a 2003 Mitsubishi Eclipse. It has 79K miles, 4 cyl engine, automatic trans and from all appearances has been left totally stock. The only obvious things wrong with it are, the A/C doesn't work and there's a few tears on the plastic facia. Other than that it doesn't look like it's had too hard a life. With 79K miles, my guess is the timing belt is about due to be changed. Is that something that's possible by a fairly experienced mechanic or is it a "dealer only" job? Is there anything '03 Eclipses are noted for that might make me want to stay away from this vehicle? Thanks for your time.

Here is an exploded view of timing. You as an experienced mechanic can do the job.

That's good to hear. I'm going to look into it right away. The recommendation is to change the belt at 75,000 miles and it's got 79,000 miles on it now. Do you have a picture of a 4 cylinder? These diagrams appear to be of a V6. Thanks again for your help.

I would have to assume that the engine won't start.
Next thing to check is compression in each cylinder.

Fuel pressure ok so is spark.
I didn't disconnect anything except the crank positioning sensor and I reconected it.

Well we can certainly rule out a easy fix. Lol
the next thing we have to know is do you have injector pulse?
But first check all the fuses. Remove neg batt cable and reconnect. The ecm has shut the eng down for some reason. Also check the plug at the crank sensor look inside sensor and plug to verify that a pin did not get bent.

When I change the timing belt on a 01 eclipse gt should I get the water pump replaced at the same time even though it may not need to be replaced cause I got quotes from reapair shops with the replacing of the water pump and without replacing the water pump

Water pump replacement? YES! You should do very well to replace your water pump the same time as timing belt. It's right there in the same area. Makes sense. & Is strongly recommended! Thanx for the post!

No fuses are blown and the positive battery cable has been off the car for awhile since I've tried to start it.
Checked the crank sensor and it looks good it only has one plug on the sensor up at the top of the engine and it also looks good

Okay I have the car started now but it is running rough.
Could it be that I have a low battery and the alternator isn't hooked up and all the other things that are disconnected?

Everything is hooked up now but it is hard to crank and runs rough when we pulled the codes it pulled a cam positioning sensor circuit failure and a random multiple misfire detected code any ideas on what's wrong?
