pull a plug and leave plug wire attached. then jump the starter relay w/key on. this will easily determine if you have spark or not, because you have view of the actual plug'. if you have spark, check your fuel pressure. you probably hear the fuel pump kick on just by turning key to "on" position, and listen carefully towards the rear of car. if you have spark, and fuel pressure (stock fuel pump is 40 psi w/key, you do not even have to start the engine), then go back to timing. spark, and fuel pressure are quick easy checks. good luck.
