ok... there are a couple of things you can do. i must have miss typed on the cap,rotor . in the back of the motor where the plug wires conect that is the cap that is bolted to the distributor with two torques bits that i believe are t15 in size. there may lie your problem. the posts inside are made of aluminum and they get coroded and dont alow the proper spark. the other commen problem is the exhaust the catalitic converter becomes pluged up. something you can try is remove one of the oxigen sensors and try to start it up if it runs the cat needs replaced. the o2 sensor is a 7/8 nut to remove it. give it a try

if you haven,t replaced the coolant temp sensor that would be the next steps i would try .if it is reading minus 40 degrease . it will dump the fuel.check for open in this circuit.if you have a scanner see what the temp is. _

get your self a fuel pressure tester, hook it up to the fuel rail, you should get at least 30 psi with key on, 30 to 45 psi with engine running.
