There is no spark coming from the coil or injectors and car has fuel. I changed cam and crank sensor but still nothing. I by mistake disconnected the fuel injectors plug that is under the hose thinking it was the fan and ran a wire from the positive on the battery ans connect it to the harness and it cause a spark. I thought it blow a fuse but i have checked all fuses and the work. I am running out of ideas. please help.

Primary voltage to several systems, including the ignition coil, dark green wire with orange tracer. That voltage comes from asd relay. There is a fuse for asd relay. To check for voltage the engine has to cranking. The control side of asd relay, the computer has to ground it before it will energize. Did you check wiring circuits for cam and crank sensor connectors before replacing sensors? Are there any applicable trouble codes?
Are you ok with testing wiring circuits?
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.
NEED TO RUN A FUEL INJECTOR FLOW TEST. SEEMS YOU MIGHT HAVE A INJECTOR . IF ALL PLUGS ARE AS THEY SHOULD AND PLUG WIRES ARE GOOD ,FUEL FLOW OR COMPRESSION IS LEFT.YOU CAN TRY MOVEING PLUGS AND WIRES AROND FROM HOLE TO HOLE TO SEE IF MISSFIRE MOVES , IF IT DOES THEN YOU MOVED YOUR CAUSE...
If you have good fuel pressure. Check for spark at any plug while cranking, If no spark, also place a screw driver on an injector and listen to it while someone cranks it over. If you have NO spark and NO injector click - crank sensor needs to be replaced. 95% other 5% hmmm wiring problem on / near crank or cam sensors, theft system active, dead pcm.......
spark comes from a couple places you want to check.
1) coil
2) crank and cam sensor
3) ECM
if you find also the injectors are not getting an injector pulse than your spark problem is leaning more towards the sensors or the ECM.
