Is replacement froze up? Is battery connected? Are all wires connected? Check to see.

look in the owners manual that may help

Sounds like two different problems. The no start could be fuel or ignition related. The loss of coolant could be an external or internal leak, including a head gasket. You would need to figure out if you are lacking spark or fuel pressure when it fails to start to proceed with testing.

It could be either a bad battery or bad battery connections. Have the battery tested . Some auto parts stores will do this for free.check battery connections for signs of corrosion. Clean thoroughly before reinstalling battery. It may be a charging system problem have a garage test the alternator. Hope this helps

Hoping the gas tank is close to empty. The fuel pump module is located on top of fuel tank. Raise car in air support with jack stands remove necessary shields and exhaust piping. disconnect fuel lines and electrical wiring remove straps and lower on a floor jack. Once out clean road debris off top remove lock ring and remove module either replace as unit or pump by itself. Install in reverse order. Your first one about 3-4 hours shops 2-3 hours.

There is a slide switch on the overhead console. It has 3 positions, on, off and auto. Slide it to the auto position and, if the switch is working, that should solve your problem.

I'm not familiar with that vehicle, but if the hose is roughly an inch in diameter it goes to the inside heater. You will need to lift the vehicle to get under it.

P0507 Higher idle speed than expected partially stuck open thermostat engine running colder than normal raises idle speed. Small vacuum leak raises idle speed. sticking throttle cable holding throttle plate open.P0741 Torque Converter Clutch system stuck off : Code conditions : No engine or transaxle system codes set, engine run time over 5 seconds , Throttle Fluid pressure switch not indicating Park/Neutral,TCC commanded On @ max duty cycle, throttle angle over 8% Trans fluid Temp input 68-248f Degrees not in fuel cut off, trans gear ratio indicates 2nd, 3rd, 4th gear delivered torque 32-150 ft lbs, the PCM detected a TCC slip value that was over the torque limits . most likely cause is bad tcc solenoid or torque converter itself. Trans shop can diagnose and repair

P0507 code idle speed is high than expected. Partially stuck open thermostat can make the computer think that the car is cold and command a higher idle speed. A small vacuum leak will also raise the idle speed. Throttle plate not fully closed cause this condition. Once problem is solved then clearing codes will leave computer monitors at incomplete which will still fail state inspection by driving the car over several days with a fuel tank between 15%-85% will allow them to run to completion. Ask your state inspector how many monitors need to run to completion the hardest ones to complete are EVAP, SEC.AIR, CAT.

Take it to your local Autozone, they will run a free diagnostic test. if new parts are needed for your car buy used parts online to save some money.

The cars computer has stored a code that can relate to the condition you are experiencing. with a code reader you can determine the area of concern

on the drivers side near the bottom of the windsheild you will see a plate with a number on it.... that number is the vin number... it should be 17 digits long... numbers and letters

If it is the north star the water pump is on the right side of the motor if I'm not mistaking the new one should come with a pulley on it if not it should just unbolt.

The lights are on different circuits, so it sounds like a problem in the wiring harness.

Code 507 is for a problem with the idle speed control being too high, and code 741 is for a problem with the torque converter clutch circuit.You would check for vac leaks and see if the idle air control valve is working, and check the circuit for the torque converter clutch.
