    What is wrong when the car won't start but the battery is fine?
    I had no problems prior to this but my car would not start today. It only has about 45000 miles on it. I turned the key and the lights came on the dash but nothing else happened. My cousin thought it was the battery so he tried to jump it but when he touched the ...

      Too many possible causes and variations. Repost after the mechanic tells you what it needs and tell us what he wants to do. Maybe the car horn went off because that is the alarm. Maybe it just needs a battery. If the battery has not been replaced in years I may be right. The alarm senses low voltage and sets it off. The dash lights require only a very tiny amount of battery to illuminate but the starter will do nothing with a bad battery or dirty connection.

      The mechanic has told me the bracket holding the wires that connected the ignition to the engine corroded and fell off. In turn, the wires hit the engine which melted the insulation and then short circuited the system. I asked him after he fixed that if there could possibly be anything else wrong but he did not answer. Does this sound correct and what other problems could I be looking at from the short??

      So he fixed this bracket and wires and you are OK now. Not a big bill?

      nope turned out the shory fried chips in the ECM. From what I could research it was an OK price for the replacement. $880?? Sounds reasonable from prices I saw online . Thanks for the input.

    How to check a coil see if bad

      You have to check the primary and secondary resistance with an ohm meter. Connect the probes to the two terminal pins for the primary resistance, connect one probe to the high-tension terminal and the other to the positive terminal for the secondary resistance. The specifications are .3 to .6 ohms for the primary and 9-15k ohms for the secondary. If you are trying to solve a no spark problem, check the igniter.

      first thing you can do is put a spark test light on it and see if it is generating any spark if it is not then test the wires into the coil for ground signal and voltage. if you have a ground a signal and it is getting the correct voltage but it is not generating spark to the plugs then the coil is likely the problem.

      Find the diagnostic connector under the hood of the Toyota pickup. Depending on the model, it is in the fender or under the dashboard on the passenger side. Refer to the owner's manual for your specific pickup. Connect terminals TE1 and E1 with a jumper wire. A jumper wire is an insulated piece of wire used to make an electrical connection. You can find jumper wires at any electronics store.Turn the ignition key on. The "check engine" light will begin to flash a pattern. The first set of flashes indicates the first number of the code. After a short pause, the second set of flashes is the second number in the code. For instance, for code 21, the light will flash two times, pause, then flash one time, dictating a problem with the Toyota pickup's oxygen sensor. Turn off the engine, and remove the jumper wire. After reading the code or codes disconnect the battery for a minute to clear the codes. Then repeat the test but after you have tried to start it a few times again. I know that it will not start, just trying to set fault codes and eliminate any stray codes that you may have set by accident while changing parts. Also tell me if it has a good strong spark. Also, try to start the engine with the air flow meter disconnected and see if it now runs. Update me.

    Have error Code P430 Engine check light on.
    Clear Code but it came back. When code is cleared car runs fine, when code re-occcur car have a hiccup at 45 to 50 MPH. Checked for Exhaust leak, have not replaced O2 sensors. Checked Fuel filler Cap. Als oother codes occurs 440, 441 etc. Any advice will be helpful. ...

      There are only two possible causes for this P0430. Catalytic Converter or the Front Air Fuel Ratio Sensor. Seeing as if the catalytic converter were bad you would replace the Front Air Fuel Ratio Sensor at the same time, it will not hurt you to replace just the front sensor, clear the code and see if the cat code returns. The P0440, P0441- look for a broken or disconnected vacuum line or hose in the engine compartment. Look good, even behind the air cleaner housing. This is the fix most times - a hose thats off or broken.

    Missing misfire on cyl. 1234

      When did this begin? If the timing belt were not aligned correct you could get the P0300 and the misfire on 1234 also. The P0420 may not be related and you may need a new cat but have to work the misfire codes first. The P0401and P0402 point to a bad EGR Vacuum Regulator (EVR) Solenoid. If it were me, I would write these codes down, clear the codes, drive the car for a day and see what codes return. What running symptoms would you describe?

      P0300 means random/multiple cylinder misfire detected. The possible causes of this trouble code are defective spark plugs and plug wires, defective oxygen sensor, defective coil, defective camshaft position sensor, burned exhaust valve, stuck/clogged EGR valve / passages, defective fuel injector and faulty catalytic converter.

      P0301 means cylinder # 1 misfire detected. The possible cause of this trouble code are defective spark plugs and plug wires, defective oxygen sensor, defective coil, defective camshaft position sensor, burned exhaust valve, poor compression, running out of fuel, defective fuel injector and faulty catalytic converter.

      P0302 means cylinder #2 misfire detected. The possible cause of this trouble code are defective spark plugs and plug wires, defective oxygen sensor, defective coil, defective camshaft position sensor, burned exhaust valve, poor compression, running out of fuel, defective fuel injector and faulty catalytic converter.

      P0303 means cylinder #3 misfire detected. The possible cause of this trouble code are defective spark plugs and plug wires, defective oxygen sensor, defective coil, defective camshaft position sensor, burned exhaust valve, poor compression, running out of fuel, defective fuel injector and faulty catalytic converter.

      P0304 means cylinder #4 misfire detected. The possible cause of this trouble code are defective spark plugs and plug wires, defective oxygen sensor, defective coil, defective camshaft position sensor, burned exhaust valve, poor compression, running out of fuel, defective fuel injector and faulty catalytic converter.

      ok. change the plugs, wires, on the oxygen sensor which one do i change before or after the catalytic converter. i notice when the engine is cold it runs normal but when it starts to warm up then it starts missing.

      P0401 means insufficient EGR flow. The possible causes of this trouble code are defective DPFE (differential pressure feedback EGR), clogged EGR passages, defective EGR valve, and lack of vacuum that’s why the EGR isn’t opening.

      P0402 means exhaust gas recirculation flow (EGR) excessive detected. The possible causes of this trouble code are defective DPFE (differential pressure feedback EGR), clogged EGR passages (more likely a carbon build up), defective EGR valve, and lack of vacuum that’s why the EGR isn’t opening.

      P0420 means catalyst system efficiency below threshold (bank 1). The possible causes of this trouble code are retarded spark timing, not working properly/faulty ECT (engine coolant temperature) sensor, damaged/leaking exhaust manifold/catalytic converter/exhaust pipe, and faulty oxygen sensor

      Well then the cause has an equal high chance of either the timing belt has jumped or the catalytic converter is clogged. You can confirm the clogged cat by removing the oxygen sensor closest to the engine and if the power comes back that confirms it. A clogged cat can cause all those codes.

      Replace the Exhaust Gas Recirculation (EGR) Vacuum Solenoid Valve (VSV). This is different than the modulator that you replaced.

      The EGR VSV is located on the bottom of the intake manifold.
