Guys, I have found out that Ecm 1 fuse is blowing. As soon as I replace it and turn the key to the ignition. Fuse get blow again and again which is preventing the car to start. Obd 2 scanner is not showing any error.
1.....
The ECM 1 is one such computer; it has a fuse is installed to protect the computer from sudden power surges or other component damage -- the fuse will blow before any damage can reach the ECM. Many component defects can cause your ECM 1 fuse to blow.
2.......
Another cause of an ECM 1 fuse consistently blowing is a fuel pump problem. When the fuel pump begins to fail it overheats, causing it to drain more amperage (amp); if the amps exceed the amount of amps the ECM 1 fuse allows, the fuse will blow. Replacing the fuel pump should correct this problem.
3.....
The ECM 1 operates via voltage sent from the battery. Anytime an electrical wire becomes frayed, burnt or damaged, the wiring leading to the ECM 1 will short-circuit; once a wire short-circuits, a power surge can occur; if the power surge exceeds the ECM 1 fuse's limitations it will blow the fuse. It is hard to track down a short circuit, but you will have to look at every wire leading to the ECM. It is best to have a qualified technician -- with the tools and devices to narrow down the specific wire causing the short -- work on such fuse problems,
Good Luck...
Till now I am trying to start it but Check engine light is flashing rapidly. I have check the fuse box in the bonnet and all the relays and fuses are good. What could be the reason? Any ideas guys?
