Ihave changed the crank sensor and the coles on the plugs but still the it wont give a spark.
Ihave changed the coles on the plugs and changed the crank sensor the one next to the crank pully. But still it wont spark. Is there a fuse on this car for the coles or sensor?

You Changed a lot of parts but did not say weather or not the engine is firing or not. if its not, Take an extra spark plug. pull one of the wires from a cylinder and put the plug in it. lay it on the engine block or frame so the plug is touching metal. have someone crank the engine over and see if the plug has spark. This is the easy way if you don't have a tester. MAKE SURE you are NOT touching the plug or wire while cranking the engine over or it will give you one heck of a Shock.
These vehicles are notorious for having shared ground wires that crack or rot and give poor connection to the PCM (power control module)or one of its sensors.
Ihave changed the spark plugs the coil pak and the fuel pump ??????? Before replacing parts did you test the electrical Circuits for the fuel an ignition systems > You don't even know which system the problem is in . Hooking up a fuel pressure gauge an checking pressure and flow , Pulling a plug wire an seeing if there is spark.
And it does crank . a crank no start condition . if the starter didn't spin the engine it would be called a no crank no start problem . Your best bet ,take it to a qualified repair shop . That has the diagnostic tool's and knowledge to diagnose the problem ,an not just replace parts .
047 Engine Hard to Start or No Start Scan Data for Ignition
Did you test power an grounds ? B+ to coil pack . Check for battery voltage at dark green with orange stripe wire at coil pack . No B+ voltage there you need a ASD relay - auto shut down relay !
Any codes set? If not, run normal diagnostic checks, such as is are the plugs getting spark? Test fuel pressure, check for injector pulse using noid light, and check that timing belt has no broken. Next would be test crank/cam sensor.
Were both engines the same year? Some model 2.5's had different crank angle sensor tabs on the timing gears. Usually, if that's the problem, you will have spark on 2 cylinders and none on the other 2 and none will be fireing at the right time.
you will ned to change the coil for the spark plugs the main unit its not giving no spark and will have to set up spark postition idle to ,if my info was of any help to you please leave a commeny,note,vote.thankyou
if you are saying there is no spark to the plugs the first thing to ascertain is there switchiing at the coil
to check this you need to connect a test light across the coil and crank the engine over if the test light
flashes on and off triggering is taking place that means if there is still no spark that the problem could
be a faulty amplifier or module or power transistor if one is fitted.if no flashing at coil terminals then it could be a wiring fault coming from the ignition switch in which case you need to check wiring back to the switch ,the switch itself , the wiring to and from the ECM. hope this helps.
The car is Toyota runX 2005
