Try disconnecting the wires from the starter and try it again. If it blows the fuse again, then your ignition switch it'self is probably shorted. If it doesn't blow the fuse, your starter is grounded on the inside and needs to be replaced.

More like a short than a bad ground. A bad ground would do nothing. Somewhere in the circuit it is shorting before the load.

Check your cigarette lighter, it may be shorted. Also check all interior lights for bad bulbs. If not need to know how good you are at electrical work. Next steps can be tricky. Let me know.

SOURCE: 93 corolla 1.8 No start Blown ignition fuse

I had a prolem like this one time a while back. what i did was got the wiring diagram and checked everything that was running through that 30 amp fuse. on the one i was working on it ended up being an injector wire pinched under the valve cover and it didnt short out till the car was driven til it warmed up and expanded after the valve cover gasket was changed. hope this helps!

SOURCE: ignition fuse keeps blowing when i turn the key

It MUST be the starter relay coil - or the power wire that feeds it. Likely a short in the relay coil (AKA starter selenoid).

My car will turnover but not start.


There are several reasons why your engine turns over but will not start:
1. Defective ECU/ECM sensors (ie mass air flow, throttle position, camshaft position, etc.)
2. Defective ignition system components (ie ignition coil/ignition unit, pick-up coil, etc.)
3. Wet ignition components
4. Low cylinder compression
5. Valve clearance not properly adjusted
6. Worn or incorrectly gapped spark plugs
7. Broken, loose, or disconnected wires in the ignition circuit
8. Defective or weak fuel pump
9. Clogged fuel lines
10. Water in fuel

30amp AM 2 fuse blows as soon you turn on the key & car will not start


This is common about this time on these Camrys. I own three. The AM2 fuse is blowing because a coil, capacitor, or supressor has gone bad in the distributor. To test this disconnect the two wire connectors to the distributor. Replace the AM2 fuse. Turn the ignition. If the fuse doesn't blow. The distributor.

What other than starter or voltage regulator would not let 1966 buick skylark turnover


HI. This could be as simple as a faulty wire or a bad ignition switch assembly. Use the procedure below to isolate the culprit.

1.Check for 12 volts on the large wire attached to the top terminal on the starter relay. It should have battery voltage. If not, the battery, terminals or wire is bad.



2.Check the small wire on the solenoid for power when the key is in the start position. Remove the small wire on the solenoid and have a helper hold the key in the start position. Check the wire for battery voltage. If there is voltage, the starter is bad. If there is no voltage, replace the wire.



3.Check the fuse in the fuse box under the hood on the left fender well. If it is good, check the relay by pulling it out and checking for power at one terminal with the key off. If there is no power, the problem is in the fuse box between the fuse and the relay. If there is power, have the helper hold the key in the start position once again and check for power at another terminal from the ignition key. If there is power, the relay is bad. If there is no power, the starter circuit is suspect.



4.Check to see if there is power to the neutral safety switch if there is no power at the relay. Use the voltmeter to check for power with the key in start. If there is power going in, check for power going out. If there is no power going in, the security system or ignition switch is suspect. If there is power going in and none coming out, the switch is bad. If there is power coming out, the problem is between the neutral switch and the relay.



5 Remove the cover on the bottom of the steering column. Check the solid yellow wire for power when the key is in the start position. If there is no power, the ignition switch is bad.

2000 Grand Voyager blowing the ignition fuse


Was the old fuel pump bad? It might be worth the cost to replace the ignition switch. The wires to the fuel pump would be a second guess if the old pump was bad and burnt the wires before the fuse went. When you eliminated the fuel pump you also eliminated the wires to the pump and it started. Then you replaced the pump, but not the wires. The ignition switch is the other end of the circuit.

30 amp ignition fuse in engine compartment blows at start


It sounds like a bad ignition switch or something is grounding out.Try to isolate the problem to key positions.See if the fuse blows when you turn the key to ACC(when your dash lights come on without starting)If the fuse does not blow then when you go to start it and it blows it could be one of many problems,the more common ones could be ignition switch,wiring,starter relay,starter soleniod,or perhaps the starter itself is shorting out,this can sometimes happen when a starter goes bad.

Blowing a 40 amp ignition fuse everytime I turn the key over. Suspect short in starter


It is a grounding problem.Your motor does not have a good ground from the motor to the frame..Bad starter will not blow a fuse. Clean all of the grounding straps especially the big ground wire from the battery to the motor. Bet if you check that little ground from the battery to the frame it will be melted..because the main ground to the engine is bad..
