Check to see if the timing jumped. Crank the engine over to top dead center and see were the rotor on the distributor is pointing. It should be on the #1 cylinder. The way you get it to top dead center is pull the #1 plug and stick your finger in the hole. Have someone turn it over slowly and when it blows your finger out it should be at top dead center. Also check the pressure on the fuel pump to see if it is getting full pressure.

Check the fuel pump have some one turn the key while you go over to the fuel cap were the gas goes put your ear there and listen for a buzzing sound if you hear it thats the pump if not its not working.

Now if the pump is working does not mean its working fine, check the psi's on the fuel and make sure its in proper psi range.

Next check for spark. Take the coil spark plug wire off the cap (the center wire) and set it 1inch away from the center tip you removed it from don't hold it with your hand you don't want a shock. While watching have someone turn the key over and look for spark coming from the cap to the wire. If present you have spark if not theres your problem.

The cause is either timing is off or the ignition module is bad.

Hope this infor is helpful
