20 amp fuse keeps blowing engine won't start, fuse

You look up the circuit that blows the fuse in your owners manual

You then need wiring diagrams to figure out why a fuse blows &
solve the problem,you don't replace the fuse, only to have it keep
blowing

Hi,
Who installed the engine? If you did, check all the Grounds/Earths under the hood/bonnet. If the mechanic/shop did, take it back and have them fix it.

Td

look inside the socket coin fall into the socket

Pls be more specific, doe's this fuse keep blowing or what? Fuse blows and your car won't start. I have a 2004 GTC and the #8 fuse kept blowing, had to replace the starter, (it was pulling 80amps instead or the normal 30-35) once the starter was replaced, no more starting issues and the fuse no longer blows. Hope this helps, good luck

Check your tail light and other running light sockets for corrosion.
Pull each and every bulb to check it, also check the back side of the socket.
(Your headlights are not part of this circuit.)
Rust or water with rust will conduct enough current to blow the fuses.
Please revert back to the 20 amp fuse, as you may damage the wires leading to the bulbs in places you won't be able to find or fix.
It's unlikely that it's one of the actual light bulbs, all light bulbs tend to go open instead of shorted, but you can check them too.

There are a few things you can check. The first thing and most likely what the problem is would be the fuel cut off switch. Below is a picture of it the location of it. Where you see the blue arrow pointing down is where the button is that you push to reset it if it is "popped". If that is good the next thing you can check is the fuse for the fuel pump. That fuse is located in the power distribution box located in the engine compartment under the hood (picture of that location below as well) I also gave you a diagram of the layout of the fuses with numbers. The fuse for the fuel pump is the fuse located in the number 10 position and should be a 20 amp fuse. Last you may need to check the fuel pump relay. That relay is located in the same fuse panel and will be the one marked number 301. I hope this helps and good luck.

FUEL PUMP WILL HAVE A 20 AMP FUSE.LOOK FOR BLOWED 20 AMP FUSE IN THE ENGINE COMPARTMENT FUSE BOX.

Look in your owners manual in the index for fuses, find the page and it will tell you what runs on the #6 fuse. Tell me what it says and I'll try to help you figure out the cause. Whatever you do don't put a bigger fuse than 20 amps.

Here is an idea, when do you blow the fuse key on, key on engine running, key on engine running hitting the break pedal? Try and get the key on without blowing fuse if possible, then one at a time try those circuit loads ie: horn, brake pedal and so on, if you isolate which load is pulling to many amps(blowing fuse) unplug that load itself, then restart testing, see if fuse stays ok. You can also substitue the fuse with a circuit breaker and unplug each load until click(of breaker) stops.
