When I turn key I have power but does not engage starter. How can I be sure it's not the starter but maybe a fuse or relay before I change out the starter.
My car has an automatic transmission.
To determine whether you need a new starter, the Mechanic would use a voltmeter to measure the voltage supplied to the starter solenoid with the ignition key in the "start" position, as well as measure the voltage drop on the heavy cable from the battery that powers the starter motor. With the key in the start position, you should be able to measure battery voltage to the solenoid. If there is power to the solenoid and the heavy cable is in good shape, that would mean that the solenoid and/or starter motor are bad. On the other hand, if there is no power to the solenoid, or the heavy cable has high resistance or an open, those circuits have to be traced to find the open.

There are a few reasons why your Toyota Camry won`t start
According to VEHQ, the top five reasons could be a dead battery, a defective alternator, a broken ignition switch, a clogged fuel filter, or an empty gas tank. Of course, you can rule out the last issue by simply looking at the fuel gauge.
Starter – Your starter may be loose, so make sure it is bolted in place. Injectors – A bad injector can keep the engine from firing. Cold Start Valve – If the engine is cold and the cold start valve is bad, it can keep your car from starting.
If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you`re dealing with a battery or an alternator problem.
Hard start symptoms and starter failure may NOT be caused by the starter, but could actually be caused by the crankshaft position sensor. If your vehicle is experiencing one or more of these symptoms, the crankshaft sensor may be at fault.
Connected to the battery is the alternator, which works to generate power for your vehicle`s electrical components. When you have a brand-new battery but still can`t start the car, the alternator might be the issue. Cold and damp climates may increase wear on an alternator, causing it to fail.
And if that`s faulty or the fusible links are damaged, your car wont start. A damaged or blown fuse can prevent power from reaching the starter relay, which is needed to provide the spark, the ignition, and the power to move your vehicle.
Connect the remote starter switch to the battery positive and the solenoid (smaller wire) terminal on the starter and click the switch. If nothing happens, you`ve got a bad starter. If the starter turns, the problem is in the electrical system.
The starter relay is most often located under the car hood, found in the power distribution center. It can also be located in the fuse block in the cabin. The relay has wires coming in and out of it. However, there are many other relays used in the car that look similar.
Push-start the vehicle if you have a manual transmission
Once you`ve got some speed going, release the clutch and your car should start. Press the clutch back in and give your engine some gas and you`re good to go! This will definitely work with a bad starter, but it could also work with a bad battery.
Car not starting: Another symptom of a faulty ignition relay is a no power condition. If the relay fails it will cut off power to fuel pump and ignition system, which will result in a no power, and therefore no start condition.
One of the best ways to determine if a car fuse has blown is by using a test light. It should illuminate both ends of the fuse, and, if it doesn`t, it needs to be replaced. Sometimes, a blown fuse is caused by a damaged wire, motor, or other part.
If you don`t hear clicking when you start the engine, the problem may be a dead battery. If you hear clicking, but the engine doesn`t crank, the starter might not be getting enough electricity. Using your owner`s manual and a voltmeter, you should be able to test functionality.
The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.
Starter motors should make noise when you turn your ignition key fully to activate your car. If you turn the key and do not hear anything, there`s a chance that there`s something wrong with the vehicle`s ignition switch.
Use a circuit tester to see if the current is getting to the solenoid. Place one lead of the circuit tester (test lamp) to the feed terminal of the solenoid. Attach the other lead to bare bodywork metal. If the tester lights up, then the problem is with the solenoid or the starter itself, not the current getting to it.
The MAF can become clogged with excessive carbon build-up from the combustion cycle, or sometimes by road grime. If it is too dirty, it will be unable to correctly measure the air fuel ratio, and cause your car to not start or exhibit other unusual symptoms.
Car Will Not Start: Over time, as the camshaft position sensor fails, the signal it sends to the engine control module weakens. When the engine no longer receives the signal, you will not be able to start your car.
If you`ve replaced your battery but the engine still won`t start, it could actually be an engine problem. A seized engine won`t turn over, and that often resembles a bad starter or dead battery. If you suspect that your problem stems from an engine issue, it could take hours to diagnose and repair.
The battery can be fully charged but still not be able to start the vehicle if it is failing or has a dead cell. Other likely issues are the fuel pump, ignition switch, battery cables, starter, or a clogged fuel filter.
Dead battery: A dead battery is the most common cause for a 2004 Toyota Camry that won`t crank. will likely cost around $350. Alternator problems: The alternator in your 2004 Camry is the car part that turns mechanical energy from braking into restorative power to charge your car`s battery.
