Question about 2001 Chevrolet Tracker
Discover one 20 amp fuse blown,it seem that the afther market alarm system is overloading a circuit and blowing fuses causing the engine not to start.the fuse pump will prime for a few second, when attempt to start engine the fuse will blow.
It appears that it is part of the fuel pump circuit, so I would concentrate on wiring harness & connector at fuel pump, clean it real good, and apply dielectric grease to the connection, as well as the fuel pump relay, connector & harness.

that fuse feeds power to fuel pump relay circuit that feeds pump could be defective pump,or damaged circuit wires that shorts out! and not a good idea to put higher fuse in circuit could cause more damage to circuit! but i know when your stuck, u do what it takes,so inspect circuit related to fuse,

You should be able to take it to the dealer and have them disable the VTSS. Look for about an hour labor to do this.

SOURCE: Blowing ECM-B fuses
The ECM-B fuse is a 20 amp fuse, and you should NEVER put a larger fuse in to try to overcome any problem. The oil pressure switch is a secondary concern; there is an idiot light or oil pressure guage in the dash to alert you to oil pressure problems. Under heavy load, such as towing, your engine requires more fuel, and if your fuel pump is going/has gone bad, it cannot supply the demand.
The problem is almost certainly a fuel pump wire harness short, caused by a dying fuel pump. I have both had this problem myself, and repaired it on three other vehicles. On my vehicle, the wire harness had welded itself together when the fuel pump locked up, and the wire harness caught on fire.
The fuel pump is in the gas tank (of course my tank was full), and the tank has to be dropped to access it. The wire harness is modular, with plugs at both ends, and can be bought from the Chevrolet or GMC dealer.
If you put an incorrectly-rated fuse anywhere in your vehicle's electrical system, the WORST place to do it is where you have--the fuel pump circuit. Fuses blow for a reason, and the manufacturer's engineers properly size the fuses for the application at hand. Please don't do that again.
This can be a very dangerous problem and repair, and no, it is not cheap.
Do not attempt to operate this vehicle until you have had the problem properly corrected. Good luck.
