Why doesn't My truck start after changing the Timing belt on My 1999 Ford Ranger?

SOURCE: need to time the engine ..trying to put new timing belt on it accidentally moved the top sprocket a bit and lost original timing not starting now...worked perfect before need to know how to put it

you will need to pull the distributor cap off and pull the #1 plug out and timing covers need to come off leave the harmonic balance on or take it off an put it on temporally so you can line up timing marks. with the #1 cylinder at top dead center and the rotor pointing to #1 plug put air into the cylinder to see if it holds compression if it does your in the right postion. Next trun the crank until the cylinder is at the top of the stroke power stroke, next make sure the harmonic balancer marks are lined up next look at the two timing gears I believe they are supposed to point towards each other if not move the one you think is wrong one tooth in the direction oppisite of the way it slipped if it is not lined up you will not have compression pull valve covers off so you can see the valves both the valves should be fully closed on the # 1 plug if it is your timing should be right if one is slightly open then tuen it till the #1 valve is closed and the gear marks line up then slide the belt back on once you are sure you have it set correctly put it all back together to set the timing with the light look at the hood and under the hood it will tell you how to set the timing and how many degrees they very from engine to engine where it was manufactured for and you need to follow the emmison sticker timing proceedure, if you need more information let me know.

SOURCE: hello , i have a problem with my 1996 ford ranger

code 1131 refers to the upstream O2 sensor before the cat converter.(NO heated sensor detected)
code 1116 means the water temp signals are out of range.(Maybe its unplugged?)

The codes for the O2 can also mean a Lean condition which may be caused by a vacuum leak.

Regardless of the electronics you should be able to do a compression test and figure out if the valve timing is off.

Remember to wipe the memory after you change things to see if they helped.

SOURCE: Timing marks on 1999 Ford Ranger 2.5L.

Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

1. Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.
2. Loosen and position the power steering pump mounting bracket and position it aside.
3. Remove the four timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.
4. Loosen the belt tensioner pulley assembly, then position a camshaft belt adjuster tool (T74P-6254-A or equivalent) on the tension spring rollpin and retract the belt tensioner away from the timing belt. Tighten the adjustment bolt to lock the tensioner in the retracted position.
5. Remove the timing belt.

1. Install the new belt over the crankshaft sprocket and then counterclockwise over the auxiliary and camshaft sprockets, making sure the lugs on the belt properly engage the sprocket teeth on the pulleys. Be careful not to rotate the pulleys when installing the belt.
2. Release the timing belt tensioner pulley, allowing the tensioner to take up the belt slack. If the spring does not have enough tension to move the roller against the belt (belt hangs loose), it might be necessary to manually push the roller against the belt and tighten the bolt.

1. Rotate the crankshaft two complete turns by hand (in the normal direction of rotation) to remove the slack from the belt, then tighten the tensioner adjustment and pivot bolts to specifications. Refer to the necessary illustrations. Make sure the belt is seated properly on the pulleys and that the timing marks are still in alignment when No. 1 cylinder is again at TDC/compression.
2. Install the crankshaft pulley and belt guide.
3. Install the timing belt cover.
4. Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the cooling system.
5. Position the alternator and drive belts, then adjust and tighten it to specifications.
6. Start the engine and check the ignition timing. Adjust the timing, if necessary.

SOURCE: timing belt broke on a 95 ford ranger.new belt

you have to line up the two marks on the gears and set the tension to the correct setting. then check the marks again. trial and error. i just did my timing belt on my ranger haha

SOURCE: have a 2000 ford ranger, 2.5 engine, timing belt

Damn. Bad news friend. That truck has what is known as an "interference engine" Which meant that if the timing belt brakes while the engine is running the pistons will hit the open valves and destroy them and possibly damaging the pistons as well.

So now you either need to do 1 of 3 things, 1 have the head removed and rebuilt, 2 have the head removed and replaced with a new/used one, or 3 replace the engine entirely.

If you replaced the belt yourself then you are probably capable of replacing the head yourself. Just get one from a junk yard, swap it for the old one and your good to go. While you have the head off take a look at the pistons to make sure they are ok.

Personally I would just swap the engine for one from the boneyard. They are relatively cheap. I'm sure this is the last thing you wanted to hear but unfortunately until you do one of the 3 things i mentioned she will never run again. Good luck, If you have any more questions shoot me an email [email protected]
