Fuses That "Blow" Repeatedly
Without being able to "hands on" troubleshoot the circuit served by the repeatedly blowing fuse, none of us can identify the specific defect which is causing your problem.
Therefore, the following generic answer can be applied to any electrical circuit, whether in a vehicle, or in a building, whether direct current [DC], or alternating current [AC].
Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] and other components from short circuit conditions and/or overload conditions which cause an extremely large flow of electrical current [measured in Amperes], which causes overheating of the conductors that results in damage to the insulation and the conductors.
And in a worst case scenario, the probability of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.
When a fuse or Circuit Breaker [and replacement fuses, or repeatedly "tripping" Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
The fuse or circuit breaker is doing what it was designed, intended, and installed to do; that is to protect the conductors and components of the circuit which it serves.
The proper "fix" for this issue is for a qualified technician, who knows what he or she is doing, to troubleshoot the involved circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse or before resetting a circuit breaker].
Some ignorant few people will suggest installing a larger fuse or breaker to solve the problem, BUT that will only increase the hazard, not correct it.
Do not follow "bad" advice by installing a larger fuse in a misguided attempt to correct the problem. To install an oversized fuse would almost guarantee damage to the wiring and the probability of an electrical system fire.
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.
It is very common for the starter to be the cause of that fuse blowing.
Short in the wiring or a bad fuel pump.
the fuel pump tank wiring is faulty at the pump
Fuel pump
I have a 91 240SX and had a similar issue, my Fuel Pump had to be replaced.
An electrical short between the fuse and your fuel pump, I would replace the fuel pump first..
Disconnect the harness at the fuel pump and replace the fuse. If your fuse doesn't blow after turning the ignition on, you probably have a bad fuel pump, check it for shorts.
You may have a problem in the pump. Take it off and check .
You have a bare wire that keeps shorting out & blowing the fuse, I had the same problem. The wire is the one that runs from the fuse to the fuel pump. The casing has melted away and now the wires are touching.
Where can you find a diagram for fuse panel in a 2003 Mazda Miata?
most likely a faulty fuel pump.
