Pull plug wire and install a philips screwdriver into the plug wire get it 1/4 inch away from a good ground and crank the engine over, is there spark? if so check that you have fuel pressure buy renting a fuel pressure test kit from schucks or auto zone and turn the Key to run position with the gage hooked up, it should read 50 PSI turn key off and wait 20 seconds should still have 20 PSI of fuel pressure, if no fuel pressure check fuel pump relay, then check fuse to pump. if you have a bad relay and are not getting fuel then check the oil pressure switch to see if you have oil pressure at the switch if no pressure then the oil pressure safety switch has died and needs to be replaced and should stark after replacing. If you have fuel then check the timing to see if you slipped timing belt.

if you are getting a miss fire or arc and losing most of your spark you can check this by waiting until its either dark out or in a dark garage . better to do it at night . get a spray bottle - fill it with water and go to your car . while the engine is running ( get a freind to help if the car wont stay running on its own . have him or her push the gas peddle just enough to keep the car running at idle speed ) you take the spray bottle and spray over the plug wires , valve covers, manifolds . turn out any flashlights and look for a blue spark. or blue flash. make sure everything that the plug wires are touching is wet. if you see flashes and or here snapping sounds then there is your answere. you have a bad plug wire or wires. if that fails to answere your problem check the coil. it depends on how bad the coil is but it can range from starting and running in drive and neutral ,but will die or run very rough when put in gear.
