By changing the rotor button, this would not cause the timing to be off. As long as you don't remove the distributor a and turn the engine over. If your car is running rough it could be the wires were put on wrong, or a plug is fouled, You could have a bad plug wire. It's many options that could be the problem.

THIS IS NOT A DIY JOB! You will need to remove and replace the timing belt and tensioner. It requires the removal of several major vehicle componants. Unless you have prior mechanical experiance, DO NOT try this at home. Major engine damage will result from improper engine timing.

When should I change the timing belt on my car?

The philosophy "if ain't broke do not fix", doesn't work for the timing belt. If it broke, then can bend valves and put a hole in the piston. Normally the engine repair cost much more than a timing belt change. Worn timing chain/belt can cause engine to run rough, decrease the power, and fuel mileage, and even worse, the engine refuses to run at all. It is difficult to check the wear on a timing belt, because access difficulties, so plan to change the belt at recommended intervals. As a rule, most OEM recommend replacing OHC rubber timing belts at 60Kmiles, but there are exceptions. Porsche, Volvo recommends belt replacement at 50K up to 100K depending on engine models. Acura, Audi and Chrysler allow 90K between belt changes. Ford, Mercury and Toyota up to 100K, but not for all engines. Changes in belt materials have improved belt durability to 100K, where "long life" materials are used, as "highly-saturated-nitrile" (HSN).
Timing chains usually gives some warning signs before they fail (but not with belts). Noise from inside the timing chain cover indicates that it is overstretched. You can check the status of a timing chain by removing the distributor cap and turn the crank shaft pulley in one direction (VERY SLOWLY) until distributor rotor moves, mark with a chalk crank shaft pulley to engine. Now turn it in the opposite direction (VERY SLOWLY) until the distributor rotor starts to move the other way. If the crank pulley has to be turned more than half an inch to move rotor, the timing chain and sprockets, are worn up, and have to be replaced.
While changing the timing chain/belt, it is easily accessible for other jobs, such a water pump replacement, so it is a good idea to replace other belts, and the water pump. Make sure to send your car to professionals. It is not rare for people to have problems with engine after replacing the timing belt. In all my cars I do it by myself. It is not impossible, but you will spend more time than a professional. If you decide to do it by yourself, then get the Haynes Repair Manual (Based on a complete tear down and rebuilt), specific for your car. Go to the part Engine, and use the chapter Timing belt removal inspection, and Top Dead Center (TDC) location, and put the number one piston at TDC on the compression stroke. This can be found by putting the thumb over the spark plug hole and the pressure will push your finger upward till piston reaches the upper point. This can be done by inserting a long blunt object into the spark plug hole. Note the point where the object stops moving out this is the TDC.

One of several possible issues. Check for any vacuum leaks. If you have an external fuel filter, have you replaced it ? If filter is internal with fuel pump, inside fuel tank, may want to do a fuel pressure test first.

Have you checked for any codes in your engine control module ?

1975 Datsun (ie. mechanical fuel pump). Carburettor, electrics (inc. battery all good) fuel strainer all good. On cold start engine needs to be cranked several times. Warm start is invariably immediate. ...

Carburated vehicles ether have an automatic choke, or the very old ones, a hand choke. Yours has an automatic choke. The starting problem likely is a problem with the choke. The problem is almost certainly not the fuel pump.To set the automatic choke, push the accelerator to the floor, and RELEASE. Then start the engine just like you would a fuel injected vehicle. If this doesn't solve the problem, then the automatic choke needs to be repaired.

How to change distributor and rotor on 1995 chevy blazer

If you're talking about the distributor cap and rotor. I dont know what size engine you have, but it's pretty much the same. Mark your wires with a piece of tape and write a number on each one. When you remove the wire from the cap, ONE AT A TIME, mark that location on the OLD cap with the same number. (you can remove them and immediately put them on the new cap IN THE SAME LOCATION, but it can get in the way) After all the wires are off, take the two screws out of the base of the cap and lift up on it.

Now...Take the two caps and place them next to each other, and mark the new cap exactly as you did the old cap.

Leave them there for a minute. Go back and take the 2 screws out of the rotor. Place the new one in place and tighten,first making sure you have it in the right position. Look at the bottom. There should be a square prong, and a round prong. They're there to make sure you don't put it on backwards.

Go back and get the cap from where you left it and put it back on in the same position. Put the wires back on starting with the last one you took off and work your way back to number 1.

Don't be afraid to take a picture of it before you start. Just because.

Timing off

1st, Confirm that the distributor rotor is getting spun by removing the distributor cap and watching it while someone cranks the engine a couple of turns.
If it isn't turning, you've got major internal engine problems (timing belt or chain broken, etc.).
If it IS turning, you may still have major problems... distributor jumped a tooth or teeth or the pin that holds the gear to the distributor shaft may have sheared.
If the rotor turns and is in the correct position for Top Dead Center for cylinder one, then you might have something as simple as a severe vacuum leak from a bad hose... something HIGHLY likely in a vehicle this age.

My 1983 260 olds is getting fire but keeps jumping time

Remove the distributor and check the gear at the bottom for missing teeth. Check for excessive play in the distributor shaft. If it checks out, Re-install the distributor and place a socket at the crank bolt. With the dist. cap off, rotate the engine backwards. While watching the rotor, see how far you have to rotate the engine before the rotor moves. If it seems like a long way, replace you timing set. You may have a severely stretched timing chain.
