The coils have battery voltage running through the primary windings, and grounded in the ignition control module. The engine computer signals the ignition module when to cut the primary current, thereby inducing high voltage in the coil's secondary windings and spark at the spark plug. The computer processes all sensor information, but primarily from the crank position sensor, to determine spark timing.
First thing I would do is charge up the battery, and check base fuel pressure with a gauge. Using starting fluid is going to be tough - its the large black hose in front of the master cylinder which is tough to get to. If it cranks over fast enough, and has fuel pressure and spark, it should start without any help.
if it not firing change the coils if thats not it then you may want to check the fuse but if not firing i would check the coil because where they are located on the engine under the mainfold it gets real hot there
Check to see if you have spark at te spark plug by removing a pluge wire from a spark plugh and get the metal part 1/4 inch away from a good ground and crank over if you se a blue spark your coil is working if not you have a bad coil or coil plate or cam or crank sensor please let me know if you have spark s I can help you more.
During cranking @crk sensor u should see up to 1 ac volt. Also if cam position sensor is @ fault u may not get a code, internal fault. Cam sensors are not availible,but rebuild kit is availible. The engine has to be set to top dead center aligning mark on crank pulley & tab aswell as mark on cam sensor itself.
