Automobile starting problems are among the most everyday.
A starting botheration is one of the most credible problems that can ensue at some end in the energy of a machine. It can be caused by a multitude of malfunctions, from the battery to a sensor. Consequent this procedure Testament expedite the method of diagnosing a starting disagreement.
Instructions
1. Turn the gloss on until the lights on the sprint come on. Provided the sprint lights fail to come on, the battery or battery connections are suspect, and you hog eliminated an engine performance complication. Whether the lights come on, essay to begin the engine. Provided the engine does not turn over (it honorable makes a clicking sound), the battery is suspect. Whether the lights are on, and the engine turns over, however does not commencement, the examination is with performance. Hardihood To pace 2 provided the engine does not turn over. Bang To pace 6 whether the engine cranks however does not birth.
2. Look the battery terminal for corrosion and security. Disinfected the terminals whether decisive by wetting them with baptize and pouring baking soda on the terminals. The baking soda neutralizes the acid and cleans the terminals. Wait for the terminals to block foaming and Disinfected with irrigate. Proceeds off the antagonistic terminal and Disinfected it with a wire brush. Do not take a spark plug out of the engine for this test. If it is a coil over system, remove the 10 millimeter bolts from the coil and pull it out of the head and insert the plug and lay it on the valve cover or in a spot where the plug is grounded by touching metal. Do not touch this during this test or you will get shocked. Provided not takings the voltmeter and research the voltage across the terminals, cerise cause of voltmeter on confident terminal and nigrescent on balky. There should be showing 12.3 or more select volts. Whether the voltage is low it is under charged or incapable of holding a charge. Booty the caps off the battery and research the cells one at a lifetime with the hydrometer. The hydrometer reading should be the identical on all cells whether all cells are bully. A fully charged battery Testament expo 1,260 particular gravity on the hydrometer. Probation the bathe flat in the battery and fill as fundamental with distilled moisten.
3. Convert the caps on the battery and hook the load tester to the battery. Clock the voltage as you press the load Press-stud for five seconds. Indication how even the voltage dropped while the load was career applied. This would indicate a bad cell in the battery and require replacement of battery.4. Check the black negative cable where it attaches to the engine and make sure it is tight. Scrutinize on the battery marker on top and attending for the CCA, or below freezing cranking amps. Compare this with the diagrams on the load tester for that bigness battery. For instance, a 550 cold cranking amp battery should not drop below 10.5 volts when a load is applied.
Check the positive cable and be sure it is tight on the starter.
5. Disconnect the small wire from the starter solenoid. Clip the red lead on the voltmeter to the small wire and clip the black lead on the voltmeter to the battery. Have a friend turn the key to the start position. There should be power to the wire every time the ignition is turned to begin. If there is power then the starter is the problem and needs to be replaced. If there is no power, check the fuse in the relay box on the driver's side fenderwell. If it is good then pull the starter relay out and check for power at one terminal. Put the red positive lead of the voltmeter in the relay terminal and touch the negative to the negative battery post to check for power. If there is power then have the assistant turn the key to the start position and check to see if another terminal has power. There should be two terminals with power when the ignition is in start. If there is power at a second terminal turn the key off. Take a jumper wire and jump the terminal with the power on constantly with one of the terminals that had no power. Try the next terminal if no response at the starter. When jumped, if the starter engages, the relay is at fault and needs to be replaced. If there was no power to the relay when the key was in the start position, then the ignition switch is at fault.
6. Insert an extra spark plug into the end of one of the spark plug wires. Leaving the counteractive terminal off, remove the beneficial and Disinfected it with a wire brush. Reinstall the terminals with the skilled antecedent. Research to distinguish whether that solved the puzzle. Have the helper turn the engine over. Stare at the plug for a spark every few revolutions. If there is no spark, there is an issue with the engine management system. Take the car to a shop with the right test equipment. If you see spark, the problem is in the fuel system.
7. Stare at the top of the engine and locate the fuel rail on the injectors. There should be a Schrader valve on the rail. Make sure to extinguish any cigarettes or heat source like an electric light bulb during this step. Take a small screwdriver or a nail and push in on the Schrader valve. Have the helper turn the key on and look for fuel pressure at the valve. If there was no Schrader on the rail, just loosen the fuel line for the same results. If there is no fuel expelled, check the fuel pump fuse and relay located in the relay box. If these are not faulty, the fuel pump has failed and is need of replacement.
