    will the security light continue to blink? mine alternates between the batt light and security approx 5 seconds each

  • smokemedic Mar 10, 2009

    I checked the light,it was not flashing. I got the codes read and it had a p1336 crankshaft position sensor. I replaced the sensor and it runs. Thanks for the advice and to also help me rule that out.

Your antitheft system is shutting it down. You need to reprogram it. First hook up a battery charger. Then turn the key on. The security light should blink on and off. Leave the key on for 10 minutes. At the end of ten minutes, the security light will stop blinking. When it does turn the key off for five seconds. Then turn the key on. Repeat the 10minutes. Turn the key off then on. Repeat the 10 minutes a third time. At the end of the 3rd ten minute period , start the truck. It should be reprogrammed and continue to run.

    Sorry, I assumed you had no codes. At least you got it back on the road, that's all that matters.

Would using a 80 amp fuse instead of a 60 amp fuse in a 1993 Geo Metro cause problems with the starter?


It shouldn't be. The starter is going to pull as many amps as it needs. The fuse is to protect the wiring and keep the car from catching fire in case the starter fails and tried to pull more current than it should. That being said you need to change it back. 80 amps is 33% more current than what that circuit is designed to carry. Being that it's a 1993 you should probably be on your 3rd starter by now

I have a Mazda 121 that wont start, I have replaced all the fuses under the bonnet, But when the battery was reconnected the 80 fuse blew straight away... Would the problem be the relay


Unlikely a relay which would have to be very seriously kaput to cause a fuse to blow and even if it was that bad it is only a slim possibility.a fuse would blow.

Clearly there is a short circuit somewhere on one of the circuits protected by that fuse. Check in the vehicle handbook what circuits are supplied by that fuse and begin disconnecting until the fuse goes away.
To save spending money on lots of fuses for testing a headlamp bulb can be connected across the fuse contacts to monitor progress. A short circuit will cause the bulb to be full brightness and when it dims or goes out you have found the faulty circuit.

Alternatively a couple of wires can be fixed to a spare MCB from a consumer unit if you have such a thing...

When i go to start my car i blow the #11 fuse located under the hood,what does #11 fuse go to?


Hi Aaron, I'm glad to help!
Aaron, see if the fuse blows when you turn the key to the on position without trying to start it. If it does then it could be anything on that circuit. NOTE: If in fact it only blows when you try to start the engine then your problem is in the "START-RUN-CIRCUIT" which mean you have a dead short in either the wiring or something on that circuit. If you find it is on the start run circuit then disconnect the starter and see if it still blows the fuse. CAUTION: When disconnecting the starter always unhook the negative battery cable first then rap the power wire with a rag or tape so it doesn't ground out on the engine and cause more problems. Now that you've disconnected and rapped the starter wires reconnect the negative battery cable and try to start the engine, if the fuse doesn't blow then replace the starter. If the fuse does blow then reconnect the starter remembering my caution. NEXT: Disconnect the Alternator using caution and try to start the engine if it blows the fuse replace the alternator, if it doesn't blow the fuse then you have a direct short in the wiring somewhere in that circuit. Start looking for frayed wiring that could be grounding out on the engine. Hope this help and have an awesome day Aaron.

01 kia rio keeps blowing the injector fuse every time i put it in first and take off how do i fix it


You may have a shortted injector. Pull all the injector connections off, put a new fuse in. If it still blows the fuse, you must have a short in the injector drive circuit from the ignition switch to the injectors. I don't know what all is in the circuit, but you may have a resistor pack before the current reaches the injectors
If the fuse did not blow, then one at a time, reconnect the injectors. You are looking for a shorted injector that blows the fuse. If the first connection blew the fuse, disconnect that one, put in a new fuse, and start with a different injector connector. You may find one that blows the fuse, meaning it is shorted, and needs replacing.
Good luck.

L999 Chevy Cavalier keeps blowing fuses and won't start


you have a SERIOUS electrical problem. - '.
BUT which fuses keep blowing - that is where we need to start.
1. is it the ignition circuit. - - does starter motor turn over when you trun the key.
2. is it the starter relay circuit.
3. is it the starter motor circuit.
4. is it the computer circuit. - - do you have fuel pumping to the engine and cylinders.
5. none of the above. - - do you have spark at the spark plugs.

I have an 02 civic and the drl fuse blew...so I replaced it and it blew again right away!


The fuse is blowing because there is an electrical problem, probably a short, on that daytime running light circuit. The problem must be found and corrected before a fuse will stay intact. The fuse protects the wiring from getting too hot and starting a fire. So don't be tempted to replace it with a higher amperage rated fuse--you'll just be asking for an electrical fire. Fuses are simply "problem indicators" and one-time electrical power cut off switches. They can't fix problems by being replaced.

The circuit will have to be checked with a volt/ohm meter by some one experienced with trouble-shooting electrical circuits.

Blowing starter fuse could this relay or switch


Hi, to determine whether it is a short circuit on cable or the starter you will need to disconnect the battery cable from the starter and replace the fuse. If the fuse blows again there is a short circuit on the battery cable, if not then there is a short circuit in the starter motor or starter solenoid.

Short circuit in fuel pump electrical circuit


Sounds like a dead short in the wiring somewhere. Follow the wires from the pump forward and look for any chafed wires.

2001 Sebring Convertible Starter Fuse Problem


The reason that you are blowing fuses is that your starter is drawing too much current. This usually means that the starter is failing (too much internal resistance). By increasing the size of the fuse yoiu are running more current through the wires than they are designed to handle. This can melt the insulation and maybe start a fire.
