Why do I keep getting current to this

You need a new battery-
It takes a great deal more power to crank a motor than it does to light up the lights. This is why your lights still come on even though the battery does not have enough power crank the engine over. If you install a new battery keep an eye on it...if it dies quickly then you have a bad alternator.

Starter solenoid terminals maybe defective. Try replacing the solenoid.

does the motor crank when key is turned?If so check for a spark at the plugs.Get an auto electrician bypass your alarm

thats usually a sign of a vacuum leak, recheck and make sure you don't have any loose hoses, or cut intake seals

Sounds like a loose connection, Clean the fuse contacts. Sometimes lubricant and dirt gets on the contacts within the switch itself and this will interfere with power supply. Have you checked the wiper relay corrosion and wear on the relay contacts impair electrical connection. Brighten up contacts with fine sand paper and if the relay contacts are suspect, remove the cover and draw folded sand paper between the contacts until clean.

When the ignition switch is turned on the pcm turns on the fuel pump by energizing the fuel pump relay. The PCM keeps the fuel pump on as long as the engine is cranking over or running.It does this by recieving pulses from the ignition module. If there are no referance pulses the PCM will turn the fuel pump relay off in 2 seconds with the ingnition on.

Most models also include a secondary control path through the oil presure switch witch will turn the fuel pump on after it detects oil presure.cranking time will be longer if the fuel pump doesn't recieve current until oil presure switch contact is closed.

first thing to do is after trying to start engine, remove a plug, see if its wet or dry. if dry, no fuel getting there, if wet, ignition problem, then we willl take it from there

check then crank positon sensor, it control the fuel system. it tell the engine computer when to send fuel

YOU NEED TO CHECK DARK GREEN/ORANGE WIRE AT IGNITION COIL WHEN CRANKING ENGINE FOR POWER..IF NO POWER,SHUTDOWN RELAY IS NOT BEING ENERGIZED..THIS ENGINE ALSO HAS CAMSHAFT POSITION SENSOR ON END OF CYLINDER HEAD..ENGINE CONTROLLER NEEDS CAM AND CRANK SIGNALS TO ENERGIZE THE SHUTDOWN RELAY..UNPLUG CRANK SENSOR AND CHECK VOLTAGE ON ORANGE WIRE..SHOULD HAVE APPROX 8V..IF NOT..UNPLUG CAM SENSOR AND SEE IF 8V SUPPLY RETURNS..IF NO POWER TRY UNPLUGGING VEHICLE SPEED SENSOR LOCATED IN TRANS HOUSING WHERE RIGHT SIDE AXLE COMES OUT OF TRANS..IF 8V RETURNS..THE SPEED SENSOR IS SHORTED INTERNALLY..THESE 3 SENSORS SHARE THE SAME 8V SUPPLY CIRCUIT..WITH SPEED SENSOR UNPLUGGED,PLUG CRANK SENSOR BACK IN AND TRY TO START ENGINE..HAVE SEEN THIS SAME PROBLEM AT WORK RECENTLY

Remove air filter and unplug the mass air flow sensor and try again. if i cranks clean the MAF. check sensors for skewed readings that won't set codes but will upset computer.
