Replaced timing belt on 98 ford ranger 2.5,cranked it up,sounds like its out of time,but its not.could it be a sensor or could it have broke or bent something when it broke? revs up to 3500 rpm's then starts dieing out.also revs up slow.
The distributor is driven off the cam belt, if u didn't set the drive gear correctly by the book u are out of time. The distributor is driven off the cam belt, if u didn't set the drive gear correctly by the book u are out of time.

you need to pull the timing back apart pull the number one spark plug and role the motor over by hand to top dead center on the compression stroke the the mark for the crank should be lined up or almost lined up line it up perfect on its mark then set the cam to its mark install belt role over by hand 2to4 full rotation marks should line up perfect . install crank pulley fire it up for a split second shut it off and put it all back together
If your sure the timing belt is correctly installed, then check compression. you very well may have bent some valves when the timing belt broke. low or no compression will be a sign that this is the case.
You are extremely lucky as your Ranger 2.5 L is not an interference engine so you will have no internal engine damage. Both V6 engines use a timing chain and do not use a belt so you must have a 4 cylinder. The belt on your 2.5L should have been replaced at 120,000 miles or 10 years. All you need to do is have a new belt installed and inspect the tensioner and you will be good to go. You will need a Gates belt # T276. Unless you are skilled have the belt replaced by a professional.
I hate to disagreed with anyone, but on a 2.3L, will not bent valve, no matter what speed the engine was turning, 3.0L and 4.0L both have timing chains, so you must have a 4 cylinder 2.3L, check this out make sure you align the camshaft and crankshaft, remove #1 cylinder, and turn crank till piston is all the way up, that will be TDC, hope this was very helpful.
Hello gandolfph: My name is Roger and I will help with your question. I have Alldata and Mitchell on demand programs. I looked at both and neither one says this is a interference motor. That is where the valves bend if the belt breaks. I would go back and make sure the engine is propperly timed. If the cam or crankshaft are not right your compression would not be right.You can also remove the valve cover and look at the valves closely. Look for any rocker arm that is not against the cam shaft. If the valve is stuck down and not touching the camshaft. then the valves were bent. Should you need further help please just ask. Thank You for using Fix Ya. Roger
Is it possible that when the belt broke you may have damaged the engine (bent valve). Try advancing or retarding the camshaft sprocket by one tooth and see if that makes a difference.
