first it cant be bad fuel the car would atleast start, and run like crap if its bad fule. the thing if it turns over it cant be your starter so rule that out the nex thing you go 2 is spark r u getting any spark? make a quick dummy plug with any spark plug that u have laying oround that will fit into your spark plug boot and some wire ( so you dont get shoked) wrap the wire oround the theded part of the spark plug make sure you are getting metal to metal contact between your wire and plug then ground your other end of your wire to a good ground and put your spark plug in tha sparkplug boot from the spark plug that u want to check and turn over the car look at the tip of the plug while you turn over the car for a spark if u see nothing than thers your problem if you see that its firing move on to fuel. Are ur fuel injectors firing? if you have a test light this shuld be esy to test just disconnect an injector and hook up the test light to BOTH of the connectors inside the injector connector and turn over the car to see if it lights up if its working you should get a steddy blinking light while you are cranking. if id doesent ligh up than thats your problem. but this is esier to check if you have a digital multimeter and you just hook up both leads to the connector of the fule injector and check that you get 12 volts while you are cranking if they are firing check that your fule pump is workin and you are actually getting fule just get somebody to find the fule pump and listen when you turn the key to see if it comes on than if this is not the problem check all of your fusses to see that none are blown both under the hood and under the dash. also pull a plug to see if they are not fouled up cuz if they are you wont get a strong spark and will get fuel and spark but the spark is not strong enough to ignite the air fule mixture. hope this helps peace.
