I did a engine swap with a used engine i ve tryed everything but it wont start no spark i changed the cam and crank sensor but still nothing any ideras

Check some fuses or see if you are getting any kind of spark. Spark at the plugs or injectors.

Cranks shaft doesnt have a direct effect on ignition. Cam Sensor does.

Need to find out what sends the signal of when to spark ie: crank angle sensor, cam sensor etc... and where it is located ie: at front or rear of crank, front of cam etc...

Yes. No crank sensor signal usually means no spark. The ecu has to receive crank position to set spark timing. I think you've really hit a big problem. You may need to get in touch with some people who have done this mod. I've always heard it's best and easiest to swap the engine with its ecu and the wiring harness into another car. Or something more compatible with that jdm engine.

the crank sensor is on the back side of the engine just above the oil pan there will be two sensors there one is the crank sensor and the other is oil presser sensor. All so check the wires from the crank sensor to the cam sensor. If you think it is the timing belt pull the cover and check it. hope this helps.

Crank sensor is dead get a new one have it replaced/ Cam sensor controls gas / Crank sensor controls Spark

If it is cranking with out turning over I would check the fuel pump and ignition relay, crank and cam sensors.
Basically you need to figure out if you have a spark issue or a fuel issue. (as long as you didn't have a serious overheating problem). One way to help you figure this out is by spraying in some starting fluid while cranking the engine. If it starts you have a fuel problem, if nothing then you have a spark problem (assuming you didn't blow the head gasket from overheating and was running normally before this happened).
Based on what you've already done here are my recommendations:
No spark: check ignition relay
No fuel: check fuel pump relay (aka shutoff relay, aka fuel pump shutoff relay), crank and cam position sensors, fuel filter.
There is also one other possibility, that the timing belt snapped. You would need to remove the timing cover to check this.

You should be able to remove the upper front forward cam-dust covers. With these out you should be able to align the cams to their timing marks. As for the crank you'll have to rely on the timing mark on the forward crank pulley/harmonic balancer.
I hope this may have assited you. If you in need of further info or images please send a note back.

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.

You have to find out if it has fuel and spark . One or the other is missing at the demise of the engine.
