Why does my efi fuse keep blowing?
Why does my efi fuse keep blowing?
There are several EFI components protected by that fuse and any one of them can cause the fuse to blow, my bet is on the fuel pump needs replaced as it draws the most current and will draw more current as it ages. One other thing can cause it is a short to ground in the wiring, which is rare.
Why is the fuse blowing on the ASD relay?
If the fuse is blowing, it has to be because there is too much of a current draw somewhere in the circuit. The purpose of the ASD relay is to cut the power to the fuel pump if there is no Crank signal such as in the case of an accident.
Why is fuse # 24 on my fuel pump 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. The purpose of the ASD relay is to cut the power to the fuel pump if there is no Crank signal such as in the case of an accident.
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.
How does the ASD relay control the fuel pump?
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil (s). With certain emissions packages it also supplies 12–volts to the oxygen sensor heating elements. The Fuel Pump Relay is a separate relay controlled by the ASD relay input to the PCM.
