So Fix it

Remove the two Phillips head screws that hold the interior door handle in place. There is a screw at each end of the handle.

Remove the Phillips head screw on the door handle lock mechanism.

Pry off the plastic panel from the metal surround with a flat head screwdriver. Place the screwdriver between the plastic panel and the metal door and slide it in between until each plastic clip has been removed. Work around the door in a clockwise fashion until the panel is removed.

Disconnect the locking rods from the interior door handle. The locking rods connect to the handle and need to be pulled up through the bracket manually to be removed.

Remove the panel and place it on a flat surface. If the panel needs to be re-installed, do so in the reverse order of removal.

Plug the OBD I scan tool into the diagnostic port located on the drivers side dash under the steering column. The port is the same size and shape as the OBD I scan tools cable. Dont force it into the port, or you may bend the pins.

Put the key into the ignition, and turn it to the "II" position, but dont start the engine.

Turn on the scan tool. Wait for it to retrieve the codes. It will display them on the face of the scan tool.

Write down the codes.

Unplug the scan tool, and turn off the vehicle.

Open the hood of the truck and locate the battery on the passengers side of the truck. Loosen the clamp bolt on the negative battery cable end with a wrench.

Lift the negative battery cable off the negative battery terminal and isolate the cable away from the battery. Loosen the clamp bolt on the positive battery cable end with a wrench the lift the cable off the battery.

Isolate the positive battery cable from the battery terminals while you work. Since the cables are no longer connected to the battery, they can be secured away from the battery together with no risk.

Remove the cable from the negative battery terminal with a socket wrench. Disconnect the undercover on the right side of the engine, and detach the cables for the throttle and accelerator. Detach the PVC hoses and the accessory drive belts.

Disconnect the air cleaner, air intake assembly and spark plugs with a socket wrench. Detach the vacuum valve from the mounting insulator on the right side of the engine.

Place a floor jack under the engine and support the engine to take the weight off the engine mounts. Remove the insulator assembly for the right engine mount. Disconnect the valve cover with a socket wrench.

Turned the crankshaft clockwise to align the timing mark on the crankshaft sprocket with the zero mark on the crankshaft housing. Disconnect the crankshaft pulley with a socket wrench. Remove the covers and guide for the timing belt.

Detach the spring for the timing belt tensioner, and remove the tensioner spring. Loosen the idler pulley for the timing belt with a socket wrench, and push the idler pulley as far to the left as possible. Tighten the idler pulley to hold it in place temporarily.

Remove the timing belt from the pulleys and disconnect the idler pulley with a socket wrench. Mount an adjustable wrench to the camshaft to hold it in place and remove the center bolt from the camshaft sprocket. Disconnect the sprocket from the camshaft.

Remove the spring for the timing belt tensioner. Measure the free length of the spring at the inside faces of the hooks and replace the spring if this length is greater than 1.512 inches.

Align the camshaft pin with the No. 1 mark on the bearing cap of the camshaft. Align the pin hole on the camshaft with the 3E mark on the camshaft sprocket. Install the camshaft sprocket onto the camshaft and tighten the retaining bolt to 37 foot-pounds with a torque wrench.

Align the timing mark on the crankshaft timing pulley with the timing mark on the oil pump. Place the new timing belt onto the crankshaft sprocket and camshaft sprocket. Attach the spring for the timing belt tensioner and loosen the bolt for the idler pulley to apply tension to the timing belt.

Tighten the bolt for the crankshaft pulley with a socket wrench. Rotate the crankshaft two full turns clockwise and align the timing marks again. Torque the bolt for the idler pulley bolt to 13 foot-pounds with a torque wrench.

Replace the guide and covers for the timing belt with a socket wrench. Connect the crankshaft pulley and tighten its mounting bolt to 112 foot-pounds with a torque wrench. Perform steps 1 through 3 in reverse order to install the remaining components.
