You distributor cap and rotor should also be replaced. If still no spark. check the compression on the low cylinders to see if you have good compression.


What makes the engine miss.new plugs wires carb valves set the only thing i have not replaced is distributor car and rotor?

When you replaced the plugs, did you check the compression? Did any of the plugs look different than the others? Low compression in one cylinder can cause misfiring. But then, so can a faulty distributor cap.

Does engine need to be replaced when there is no compression?

If there is NO compression on any of the cylinders, you've probably slipped the timing belt/chain. Just knowing that there is no compression is insufficient information to make a decision about replacing the engine. You COULD need to have the engine rebuilt, or it's possible that a valve "kissed" a piston and the engine is toast. Or... it could be something else. If it's just low compression in one or two cylinders, it could even be caused by burned or sticking valves.


Why would a 1991 Ford Taurus 4-cylinder not run on all cylinders if the plugs wires rotor distributor cap and coil have all been replaced?

Check the firing order which is 1-3-4-2 , if it is correct you may need to have a wet and dry compression test to check the condition of the valves, rings etc.


93 Ranger 23L has poor acceleration and little power after having timing belt replaced could the pushrods have been bent when the belt snapped?

Run a compression test. If only one cylinder has low compression, it's probably a damaged valve or pushrod. If the compression is low in all cylinders the cam is probably not timed correctly.
