well if ur not getting spark and u changed all of the ignition components lets think about the computer in order for the ignition to work you have crankshaft position sensor that fires the fuel injectors and the spark change that and if still nothing then change the camshaft postion sensor that sensor tells the computer that the 1 piston has came all the way up and it tells the crankshaft sensor to do its thing
Cam and crank sensors must be gapped right. The hold down is sloted so it can be moved closer or further away. New sensor should have come with a small felt pad on the end. Push the sensor in until it stops. If the gap is to much you may get an internmitent spark. ( I have also gotten bad cam sensors right out of the box)
If you are getting spark to the plugs and fuel spray, and you have compression and the spark is at the right time, you should have explosion. Is it possible the valve timing is off - timing chain issues ? Are the new plugs fuel-fouled ?
This could be a number of things...
Crank sensor, cam sensor, coil, PCM, spark control module, ect.
Start with the sparkplugs, make sure they are firing if not work your way back from there spark pligs, wires, coil, control module, cank and cam sensors, PCM this is what i would do if this rolled into my shop.
First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
Also the fuel pump/relay would not kill the coil.
being 94' im sure it has high miles, cam and crank sensor common to fail over time do to wear and heat exposure. check the basic, make sure you getting fuel and sparks. fuel pump only work as long the engine is turning over due to the crank sensor sense the flywheel turning. crank sensor may be faulty. no sparks, check coil make sure is good and putting out 12v, auto zone can test it for free. good coil, than check cam sensor, cam sensor senses the cam turning and tell the ecu to tell the coil to disperse the sparks to the plugs. cam and crank sensors, there no way of testing it but replacing the unit unless you have the special equipment to test it; both is fairly cheap to replace, check ebay.
