Before you start replacing stuff (like distributor, cap, rotor, spark plugs, wires, etc...)

check if your timing belt didnt snap, or timing is off.

-By doing so, take your spark plug wires off (make sure you label them to ensure you put them back in the correct slots).

-Then, take your valve cover off, and spark plugs (to crank the pulley easier).

-At this point, open you fusebox under hood and take the 15A fuse out (FI injector fuse), so no fuel is being injected as you manually crank the engine.

-Next, turn your steering wheel to move wheels so you get access to the crankpulley bolt.

-Use a rachet and specified socket to manually crank the engine, always crank counter clockwise (why...because the Acura/Honda service manual said so)

-Use rachet and crank your motor to Top dead center at the same time inspect the belt if any teeth are missing or belt not snap; to do so, there is a marker on the timing belt cover right under the driverside mount, the marker should align with the white mark on the crank pulley (if aftermarker pulley then it should be the line farthest away by itself)

-To ensure Top Dead Center, take the distributor cap off, and the rotor should be pointing to the #1 spark plug wire....

_to further ensure TDC, the cam gears should also align, with up arrows point up and lines on side of gears line up.

If timing belt is off or snapped, time to change with new one (use OEM for best results), and change water pump while at it. And, make sure you tightened the belt by pushin up the tensioner pulley up the belt when installed, then manually crank engine over 3 revolutions to ensure belt is tightened with right tension.



Next, it could be your Main relay gone bad (located under driver side dash, test it if its still good (check in Acura Manual). Here ya go:







If none of above, then use an ohm/volt meter, test if you have resistance along each spark plug wire, test the resistance for Ignition Coil and voltage for Ignition Control Module inside the distributor, and check if spark plugs are not fouled or messed up.





Hope all works well, i know you sent car to shop already, but this will clear up some confusion for others.
