ok ! did you mean its got spark but does not start. if spark but does not start. check to see if its getting fuel to engine. remove air hose from throttle body and spray some starting fluid in throttle body, open throttle plate and spray some in. if car starts then stops, its a fuel problem. if no spark check the harmonic balancer on engine to see if its loose, the 3.8 engine have a crank position sensor that runs off the balancer. the rubber starts wearing out and the balancer start flopping around. and the timing gets massed up. good-day ! type in on pc browser ignition switch symtoms, and a list of things will come up. for a ignition switch controls over 50% of voltage for vehicle. good-day !
#1 NEED TO VERIFY SPARK AT SPARK PLUGS # 2 CK FUEL PRESSURE AT SCHRADER VALVE ON FUEL RAIL ,,PRESSURE DEPENDS ON TYPE ENGINE ....IF NO SPARK AT SPARK PLUGS CHECK SPARK FROM COIL WIRE , IF NO SPARK AT COIL ,CHECK VOLTAGE TO IGNITION COIL SHOULD BE 12 VOLTS, IF NO VOLTAGE AT COIL ( KEY ON ) CHECK FUSES THEN IGHITION SWITCH. IF NO FUEL PRESSURE AND FUEL PUMP RUNS REPLACE PUMP .. CK VOLTAGE TO FUEL PUMP WHILE CRANKING . CK USING PUMP GROUND WIRE AT THE PUMP CONNECTOR THIS WILL PROVE GROUND ALSO. USE TEST LIGHT TO VERIFY

Check the Belt and Belt Tensioner. If the Tensioner is not keeping the Belt tight it will cause the Problems Stated above. Please Rate my Solution, I Need all the Help that I can get! Thanks!
Easy one.This is a common problem on 88-91 Civics and CRX's.Check your main relay under the drivers side dash.It provides power to the ECU,fuel pump,and injectors.Its a squarish box with a single plug going into it held on by one 10 mm bolt.The solder joints break down over time and cause the condition you're having.You can pry off the plastic cover and resolder the joints if you are handy with a soldering iron,or just ask for a main relay at Autozone,etc.
