I have replace the fuse with a 20 amp the fuse it is suppose to have in it but it blew out again and then i replaced it with a 25 amp fuse and it started fine but then shut off after 3-5 seconds... I just wanna know what could be causing the fuse to blow.

It depends on the year make and model what is running on that circuit.
Something is pulling too much current, just like when a fuse in the house blows.

SOURCE: keep blowing fuse for fuel pump

If it takes more than a couple of hours to blow the fuse its most likely the fuel pump. If it blows instantly you could have a grounded out feed wire (+) wire or a bad relay. Look in the haynes manual to get the location of the relay.

SOURCE: 2001 S-10, Blowing "ECM Batt" fuse after running for about 30 min

that fuse feeds power to fuel pump relay circuit that feeds pump could be defective pump,or damaged circuit wires that shorts out! and not a good idea to put higher fuse in circuit could cause more damage to circuit! but i know when your stuck, u do what it takes,so inspect circuit related to fuse,

SOURCE: 2002 Sebring LXi Convertible Starter Motor Fuse Blown 2x

Starter solenoid. I don't have the page here but in chiltons a page shows the ignition to fuse to relay to starter and if you look closely it's quite basic. I had same problem with constant fuse blow #8. The solenoid over time wears and sometimes sticks. When it sticks, your system can overload thus burn fuse. I bet you never stalled out while driving, but only when you shut off and start somewhere it's a no go. That's because you're system is already engaged. I had to change starter as solenoid part of it all. I see others suffer this same problem so please share this around. Solenoid can stick for a millisecond.

SOURCE: blows fuses

SOUNDS LIKE THE ALARM HORN IS SHORTED, CAUSING FUSE TO BLOW.
TRY UNPLUGGING ALARM HORN & SEE IF FUSE STILL BLOWS.
IF IT DOES NOT BLOW, REPLACE ALARM HORN.

2005 duramax wont start replaced ficm rand one day great wont start again blew mega fuse still no start


find all ground wires in your vehicle clean and sand shiny , replace tight. will save money on parts you don't need. also older starters will begin to draw too many amps and keep blowing fuses. test starter.

20 amp ECM B fuse


check again the fuel pump. check the resistance if too low. or unplug the pump and put a fuse again, if the fuse will not blow, then the pump went bad again.

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 a 1994 Dodge Intrepid with a 3.5.The 20 amp engine control fuse keeps blowing.We have replaced the starter and the fuel pump.This did not solve the problem.When the fuse blows the engine will still...


The fuse that keeps blowing is related to your ignition. Get the faults read at a shop and find what is triggering fault and that will lead you to your problem. It's a whole lot easier than throwing parts at it, and cheaper.

HOW DO I TELL IF MY FUEL PUMP IS BAD. MY CAR STALLED AND BLEW A 15 AMP FUSE TO MY FUEL PUMP. COULD IT BE SOMTHING ELSE?


well it could be a bad wire to fuel pump....or pump is old and drawing to much current......replace 15 amp fuse and test for fuel if it blows again u can try a 20 amp fuse in place of the 15 amp ......but only to determine if pump is still pumping fuel b4 you turn on key disconnect fuel sending line to engine and get a bucket .......try turning it over and see if fuel is pumped into the bucket ....if 20 amp fuse works chances are your wiring is good....and u need a new pump good luck let me know how u make out

Fuel pumpfuse keeps blowing


Disconnect the batter. Under the hood, you should find a fuse/relay box. There you will find a Fuel Pump Relay. The back side of the box lid will have a diagram (should have) that will indicate which one is the Fuel Pump Relay. Replace the relay and try again. If the problem persists. you may need a new fuel pump. Some vehicles are equiped with a "secondary' fuel pump, usually located near the back of the engine, mounted to the frame. This one will be easier and probably cheaper to replace, vs the one in the gas tank. In my experience, even with a plugged fuel injector, an engine will still start and run, just not as smoothly. Also, check all your spark plug connections, battery connections, and starter connections. Do this with the battery disconnected. This is just a way of making sure all connections are good, in the even that is the problem. You can do this before purchasing any parts. For your battery, you can put some terminal grease on them to prevent corrosion, rust, and acid build up; a common cause for faulty connections, resulting in such issues.
I hope that this information was useful, and aids in the successful recovery of a healthy running vechile for you.
