SOURCE: car has no spark or injector pulse(new ecm,crank sensor)
Check the fuse for the injectors, some vehicles have the injectors and coil running on the same circut, at the same time check the fuse for the ignition.

WOW a 94 with 46K on it thats rare. Your computer may be bad it sends the pulse to the injector.

The injectors are mainly controlled by the good output of an auto shut-down relay which is directly affected by the fuel pump relay straight from the PCM.The easiest way to check the fuel pump relay is turn on the key,wait a minute,and see if the fuel guage comes up to proper level,helps if you know fairly close how much gas you do have.A couple other things which could cause intermittent cranking are the ignition switch may be going bad,or a bad connection in the ignition wire harness but the ignition itself is way more common.Also a near dead battery.The lights will sometimes appear somewhat bright but to start requires lots and lots of power.A good battery should read near 13V.A bad one will read around 11.8,11.9V and could cause intermittent crank.A crank position sensor could cause it,but for the most part,if a sensor is bad the system either works or it does not.That's about all except do you have intermittent start or no start whatsoever,even jumpers?If this doesn't work or you need more help,just comment here and I will get an autolink to your post and reply ASAP.Good luck!
