Fuses That "Blow" Repeatedly
Your question does not tell us what the problem is, but I suspect it may have to do with repeatedly blowing fuses. This is a common electrical problem. IF that is the problem, then the following should help you understand the challenge and what to do.
Fuses and Circuit Breakers are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating that can result in damage to the insulation and the conductors, and worse, the possibility of a FIRE which could destroy the vehicle, house, or other structure.
When a fuse and replacement fuses blow, especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
The proper "fix" is for a qualified technician, who knows what he/she is doing, to troubleshoot the circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse or circuit breaker]. Some ignorant few will suggest installing a larger fuse or breaker to solve the problem, BUT that will only amplify the problem, not solve it.
Do not follow "bad" advice and install a larger fuse in a misguided attempt to correct the problem. To install a larger fuse would almost guarantee damage to the wiring and an electrical system fire.

I suspect fuel pump or fuel pump relay problem. Try the relay first they can be tempermental and shut off whenever they want to. then if no luck check wires and connectors for the fuel pump and have it pressure tested.
