    Hi Joe Knue, I want to help you with your problem, but I need more information from you. Can you please add details in the comment box?
    I think it's in the ignition switch or key switch. It will start sometimes but as I turn the key back from the crank position it will blow the crank fuse.

    I think it's the ignition switch or key switch. It will start but then when I release the key from the crank position it will blow the crank fuse.

    My inclination would be the ignition switch. You should be able to remove it and test it with a multimeter to see if it's carrying a current.

SOURCE: ignition fuel starter fuse keeps blowing and it won't start

The earlier "fix" suggests a possible wiring problem -
more specifically, a historic issue with Chrysler products is the ground connections, which are typically insufficient.
Check both the battery to engine and then the engine to frame (firewall). If either are worn or frayed replace them. Even if it looks fine I would still replace the motor to frame cable with a heavy duty grounding strap available at most parts stores. ( doesn't have to be a specific cable - can even be homemade, just make sure it is heavier than the original and is connected to a good, bare area.)

SOURCE: starter enabler fuse blows which means the starter motor does not work until fuse is changed

It is possible that the starer is pulling too much amperage- 1st thing you need to do is find out what if any other consumers are on that circuit, 2nd you need to find out how much amperage is being consumed by the starter. 3rd test you wires most likely if a wire problem it is the heavy hot wire on the starter or the back of the alternator has a loose retaining nut

Ok well I put in a brand new starter because my crank sensor keeps blowing and thinking I fixed the problem long behold I keep blowing my crank fuse when I try starting the truck I don't know wear to start


No, year make or model. But if you blow the crank fuse, it is between the starter and the ignition switch. Could be the switch, but most likely the wire. At the relay there are four pins. 30 is B+ all the time, 87 is to the starter. 85 and 86 can be switched. But one is B+ with the key in start position, the other goes to the ECM, this would be ground.. Since you're blowing the fuse, you need to find the short to ground. this would be the 85 and 86 wires.

My GMC safari 2004 has been blowing Ignition 1 fuse (40 amps) at the moment I turn key to start position,even without starter disconnected it blowed but i replaced the fuse and i removed the starter r


The problem could be a shorted park netual safety switch . Do you know what a wiring diagram is ? It shows all the componets involved in a electrical circuit ! You IGN.1 fuse 40amp , GM calls it IGN A fuse 40 amp . It feeds the ignition switch and pin 30 at the starter enable relay .When you turn the key to the start position it sends B+ voltage to #8 crank fuse , located in the I/P fuse box ,from there it goes to the park netual safety switch , to pin 86 or 85 of the starter enable relay ! If you pull the relay out of the fuse box an look on the bottom you will see this four set's of numbers ,30,87 & 85 ,86 You can test at the fuse box where the relay plugs in . Here is a video on how to test . The guy presenting the video uses a horn circuit , but it works the same way . It happens a lot , the park netual safety switch shorting out . It may or may not be the problem . VEHICLE RELAYS Operation Diagnosis
Here is a web site for free wiring diagrams
http://www.bbbind.com/free_tsb.html Enter your vehicle info . then under system click on engine , then under subsystem click on starting . Then click on the search button an a link will pop up , click on it .You will see all the componets , connections , wiring colors etc... for the starter circuit for your vehicle .

I have a 2004 dodge stratus that has power to lights but does not turn over when i try to crank even after jumping it off.


Hi.

Check ignition switch fuse. This is a 20 Amps. see that it has not blown. In 2004 Fuse should be nr 8 in the power box under the hood (newer models #24).

Once you are sure that battery, fuse and wires are OK, check starter and ignition switch. Check if there is 12V to starter while cranking. If there is power and the starter motor does not turn, then the motor is gone.
If there is no power to starter motor when you crank, then the ignition switch located inside the steering column may need replacement. Before repairing, try reading error codes with a code scanner.

Hope you can read diagram. Make sure battery has a full charge.Not only check the fuse, check the fuse circuit for voltage, use a test lite. Also, check the fusible link. You could use a remote start button, they sell them at auto store, Hook up the leads correctly at starter solenoid. Hopefully the leads are long enough to get you out from under the vehicle, the leads on mine aren't that long. Then you hit the button to see if starter will crank the engine. If you try something like that, make sure tranny is in park or neutral and parking brake is set.
The engine isn't froze?
I can only help with testing.

Sounds like there's a grounded wire somewhere between the ignition switch and the solenoid. When you bypass the switch with the screwdriver you don't ground out the line, but with the switch the ground shorts the circuit, blows the fuse, and then won't start the engine.

My guess is that you have the wires on your starter improperly connected, and they shorted out, and caused the starter to crank the engine. You have to be very careful when removing the wires. Make sure they are pointing exactly the same way as they were origionally when you re-install them. It is very possible , now, that you may have burnt the fusable link in your battery cable, and you'll have to replace it.
