First lets see if it's missing spark or fuel do this. Remove a spark plug wire insert a screwdriver into the boot and then hold the metal part of the screwdriver 1/2 in. away from a metal part of the engine block then have someone crank the engine while you watch for spark, to check for fuel. locate and remove the plastic cap on the fuel rail then depress the schraeder valve and then have someone turn the switch on fuel should spray out. Note do these tests in this order to prevent fire. When you find what's missing, use testimonial to find out what to do next. I would explain how to troubleshoot either problem but just one is going to take long enough. I'll wait for several hours for you to reply. If you can't do it now then some other time. I hope this helps. Take care. Remember to use testimonial to reply or just say Hi! Thanks

No spark or no gas. Are you sure the gas gauge acurrate? When you turn the ignition key from Off to Run, but not all the way to start, listen carefully for the sound of the fuel pump. If you don't hear anything, check the fuse. If the fuse is good the pump may be bad.
Remove a spark plug wire and hold the metal end close to [but not touching!] a metal ground [use a pair of insulated pliers to keep from possibly getting shocked. Have a helper crank the engine. If you see a spark, the ignition is probably ok, although that's not 100% certain, as the timing or dwell angle could still be off.
Good luck!

two engine systems has things to do with this problem, fuel and ignition.
part of the system you're going to check.
fuel pump regulator(fuel) and if it has spark(ignition).
and/or
have a shop with scan tool to diagnose exactly the other problem(s).
Try some starting fluid, if it wants to run then you need to check the Inertia switch. The location of this switch is behind the passengers foot kickpanel.
There is a Reset button that you push and it will reconnect the fuelpump. Please rate my info. You can try the Reset without testing with starting fluid but the fluid verifies fuel starvation as the problem.

Do you have a question ?
Have you tried another key ?
i would check the fuel pressure first,then check for ignition spark,compression test and timing chain marks,when you run out of gas the engine backfires and it jumps timing.
