Test power to starter with a voltmeter while someone else turns the key. if you are getting power, than solenoid is faulty. If you are not getting power, than relay or ignition switch is bad. Do double check your battery connections to make sure they are metal to metal contact.

I can hear the fuel pump running, lights are on, but won't start the car.


First make sure you have good battery connections. A poor connection will give enough power to turn on head lights but not turn on starter motor. Clean the connections and ensure they are tightened.

If connections are good, check voltage of battery. It should be at least 12 volts.

If battery voltage is low, either charge the battery, or attempt to jump start the car (red to positive terminals, black to negative terminals; attached positive first, prefer to attach negative terminal to a good metal location other than the negative terminal on the battery).

If the starter motor is visible, try tapping lightly with a mallet to free it up. This may or may not work depending on the problem. If the car starts, replace the starter motor anyway or it will strand you again.

Most cars have a starter relay and a fuse for the ignition. Do a Google search on the internet for your model of car, or look in your owners manual to find the location of the solenoid and/or fuse. Replace the fuse if it's burned out. Note that a shorted starter motor could cause the fuse to burn out, so replacing the fuse may not fix the problem. Suspect a shorted starter motor or wire if the fuse burns out again. You may need some professional assistance at this point to check the solenoid.

If the solenoid is bad, it is usually replaced along with the starter. Remove starter motor/solenoid and take to an Autozone or Oreilly or equivalent and have them check its functionality. Be sure to disconnect the battery's negative terminal before removing the starter motor.

If the starter is good, then your problem is likely either your car's security system (check if security light is flashing if you have such) or check the ignition switch. If you have a mechanic friend, see if he can bypass the ignition switch and get the starter motor to turn over.

Poor electrical connections or a bad battery or a bad starter motor/solenoid are the most likely culprits.

I have no power to the ignition when i turn the key


Your battery is not providing enough cranking load for the starter motor. First try cleaning the battery terminals disconnect negative terminal first.

You either have a bad starter or ignigtion switch. When you turn the key on does everything else come on? I would check the starter first if you have power to everything.

I was having problems with my starter on a 1993 chevy suburban k1500 4x4. replaced starter, still wouldn't start. replaced battery, fuel pump, sending unit and fuel pump relay. fuel pump fuse is good. ...


Confused as to why you are replacing things that crank the engine over, like the starter, and things that are just for fuel, like the pump?

Can't tell if it is cranking over or just not firing?

But if it is not cranking, then consider the ignition switch, neutral safety switch, engine ground strap, and battery terminals.

If you think it is not getting fuel, then try some starting fluid, to make sure it does spark at least.

If it does have spark and cranks, then you should put a gauge on the fuel rail. If there is no pressure when you try to start, then check voltage at the pump with a test light.
If none, then follow back to relay.
If none there, then try jumping at the relay, just for testing.
If that works, then it could be safety cutout system.
Some vehicles use an inertial switch, some use oil pressure switch, some use alternator feedback.

1990 fleetwood starting prob.turn key nothing i can hear fuel pump the relays click i can jump starter. but nothing changed starter it was on its way out checked all fuses cheked all fuse links cheked key...


I would check the ignition switch. With a test light, check the small wire going to the solenoid for power when someone turns the key to the starting position. If you aren't getting power to that terminal on the starter, the ignition switch is not sending power to the solenoid.

2004 KIA RIO-ENGINE WILL NOT CRANK


I would guess starter fuse first, then starter. When you turn key, if you don't hear a click, you should focus your attention on the fuse first and then the starter. If you hear a click, then most likely (80%) its the starter solenoid. try to start the car in neutral to rule out the neutral safety switch...good luck
