fuses are made of tin-lead, like solder. they melt when they are heated up to melting point by the energy of the excessive current. Assuming the bus voltage is still 14V from your voltage regulator, the only other thing that could jack up the current is a decrease in circuit resistance where the current is going. so your "Fuel" circuit is at a lower resistance than it should be. This is a normal wear and tear condition for a pump motor or a relay coil to get into over a long period of time. whatever is the primary load downstream of that fuse will need to be replaced. (not a switch or the contact path of a relay, that is not the load, just a gating device) A load is a coil, a motor winding, a heater element, a light filament, something that consumes electrical energy in the form of heat, light, mechanical energy, or the like. The load has degraded insulation resistance and is passing that extra current to ground, or it has degraded series impedance, and has lost its efficiency converting electricity to work, and so now it draws more (a bit too much) to get the job done. Ohm's Law.
There's a short in your main line going to your fuel heater.
check fuel pump fuse..
My first thought is that the fuel pump is going bad and is drawing too many amps, second would be a wire grounding against metal.
not usually!!if fuse is blowing out check for short!!
it has a short somewhere in the electrical line
Defective fuel pump fuse or fuel pump relay.
The wire may be shorted to the frame.
Short in wiring, relay or pump? internal problem in fuel pump.
The fuel pump is shorting out and that is why the ecm fuse is blowing .Disconnect the the fuel pump and try it again,if the fuse blow's again then it is not the fuel pump.
Short in the wiring or a bad fuel pump.
I had a 1994 Chevy Cavalier 2.2L with the same problem. There is no hidden fuse for it just the main fuse in the fuse panel & a relay under the hood on the passenger side. It's been my experience that when this happens it is usually the fuel pump relay or your ECC. in my case it was the relay. I would have the relay checked first...... and also check for broken wires going to the relay.
Pull the ECM fuse or the injector fuse , or you can pull the fuel pump relay out of it .... all will keep it from starting
You have a bad fuel pump or the wiring to the pump is shorted to ground somewhere.
Check to insure that you are replacing the fuse with the same fuse size and type (fast blow fuses don't substitute for slow blow.) If this is ok the either the pump relay or the pump is going bad and drawing too much power for the fuse to handle.
I would repair the fuel problem-like a bad fuel pump-or bad relay-or blown fuse-or BLOCKED FUEL FILTER-or out of fuel-or bad fuel-
Yes answer: It's going to the fuse under the hood that runs your fuel pump. I think it was 18. But I'm not sure. Also you may want to try a new cps if it just turns over and will not crank.
why does fuses keep going out
There is probably a short somewhere. I would suggest you check all the wires check fro fraying, any exposure. if all is good there are you using the right fuse? Put A higher rated fuse to see if it still blows
Well it should NOT. It sounds like someone either nicked the control wires to the fuel pump and it is gettng grounded - thereby blowing the fuse or there is something wrong with the fuel pump. So take it BACK to the dealer and let them fix it!!!!
It is very common for the starter to be the cause of that fuse blowing.
One reason could be the fuel pump relay isn't working properly.The second could be the fuel pump isn't pumping enough gas thus causing the fuse to blow.
you need 30 pus
Fuel and oxygen
Well fuel is used to keep something going, and people use the internet, so internet fuel is what keeps the internet going. Answer: people, if they use the internet they are giving it fuel to continue to operate.
