Why does the fuel pump fuse keep blowing?
Fuse #24 (20 amp) is Fuel pump relay output to fuel pump. Fuse #19 (10 amp) supplies 12 volts direct to the PCM. If the fuse is blowing, it has to be because there is too much of a current draw somewhere in the circuit.
Why does my Jeep Grand Cherokee Fan quit working?
In this one we take a stab at permanently fixing a common issue with the 1999-2004 Jeep Grand Cherokee. The electric cooling fan will quit working, and your jeep will overheat, due to a failure in the electronic fan control relay. This is a heat related failure and I add a large heat sink and relocate the relay to try and avoid further issues.
Why is the fuse not blowing on my relay?
Replaced relay due to no start, vehicle started but acted as if cold circuit was not working. Drove for a few days like that and then the ASD control fuse (not the 30 amp) started blowing. Im back to square one.. Now Fuse is not blowing but the new relay is now chattering. Please help.
The fuse that is blowing is the one that operates the relay, not the pump circuit. – the relay always has power (key on) and the ECM switches the ground. Old school method I always use in these instances is replace the fuse with a higher amp re-setting fuse like on electric window motors or electric seats!
Where is the fuse on the fuel pump?
Everytime I turn the ignition on, I blow the fuse. The fuse is located in the slot marked ECMI. How do I find out if it is the pump, the relay, or anything else? I am assuming there is a short somewhere. I thought maybe I pinched a wire and am arcing out somewhere.
Can a fuel pump overload cause a problem?
If not, check the other loads on the fuel pump circuit as those other loads could be causing the problem (the overload). To check that refer to wiring diagram in Factory Service Manual.
When did I replace the fuel pump in my S10?
In April I replaced a fuel pump in my S10. When they replaced it , it blew a 20 amp fuse. They put in new fuse and it ran fine till this week. 5 months later. The fuel pump was bad and was replaced under warranty.
Can fuel pump cause fuse to blow?
a locked up fuel pump would blow the fuse. also check at the fuel rail to see if the pump is working. it may have been a clogged line that burned up the first pump which in-turn burned the fuse. and if there is/was a clog then it probably clogged the injectors as well, if fuel is making it to the injectors then you might try running a high quality fuel system / injector cleaner .
Why does the fuel injection fuse blow?
The fuel injector fuse provides power to the injectors using splices therefore enabling one wire to feed 6 injectors. A shorted wire at any of these wires will blow the fuse.
Is there a fuel pump fuse anywhere?
Yes. Almost all vehicles have a fuse in the panel that controls the fuel pump/ECU. Look under the dash, next to the driver side foot panel. Look for ECM, ECU, or fuel. There is also a relay inside the engine compartment on the driver side on the top of the firewall by the hood.
What Fuse is the fuel pump fuse?
The fuel pump fuse is located to the right of the A.I.R. relay and to the left of the horn fuse. It is marked as the ECM-B fuse.
The fuse that is blowing is the one that operates the relay, not the pump circuit. – the relay always has power (key on) and the ECM switches the ground. Old school method I always use in these instances is replace the fuse with a higher amp re-setting fuse like on electric window motors or electric seats!
Why does my EFI fuse keep blowing out?
Many Toyota owners have a problem with the electronic fuel injection (EFI) fuse blowing repeatedly. Here are some things to check: 1) The wires around the EGR tube for melting or fraying. 2) The wires near the EGR vacuum switching valve (VSV) located under the intake manifold.
Everytime I turn the ignition on, I blow the fuse. The fuse is located in the slot marked ECMI. How do I find out if it is the pump, the relay, or anything else? I am assuming there is a short somewhere. I thought maybe I pinched a wire and am arcing out somewhere.
Where are the fuses on a Toyota Ricks?
2) The wires near the EGR vacuum switching valve (VSV) located under the intake manifold. 3) Wires pinched between the intake manifold and the cylinder head. 4) Wires pinched anywhere along the valve cover. 5) Check injector wiring for any pinched locations.
