SOURCE: It keeps blowing the ECM Fuse, checked wiring but

My friend;
Try this;

  1. Did you insert same valued fuse i.e. { fuse rated 15APS with same fuse}.
  2. Check OP'S & voltage of the Alternator = 13.7 V DC - 14.8 V DC MAX.
  3. are you sure NO internal shorttings inside the ECM.

I have a 2005 land rover freelander in the engine fuse box the f3 fuse keeps blowing 15amp you start the truck go down the road fuse blows it starts runing ruff stop turn off truck then try to start wont...


15 amp is a fair current draw and for it to blow after a few minutes means that there is a short in that circuit that is allowing a drain to earth that just exceeds the 15 amp. It is in the ignition part of the system and may be a bad connection ( water ) or a problem appearing in the ECM or relay . Run fault codes to find the area of the fault. Because it is taking time to blow the fuse, it will be difficult to find. Check all wiring for rub marks .

30amp AM 2 fuse blows as soon you turn on the key & car will not start


This is common about this time on these Camrys. I own three. The AM2 fuse is blowing because a coil, capacitor, or supressor has gone bad in the distributor. To test this disconnect the two wire connectors to the distributor. Replace the AM2 fuse. Turn the ignition. If the fuse doesn't blow. The distributor.

If it "keeps" blowing the ECM fuse, it is because you "KEEP" replacing the fuse without diagnosing and repairing the reason the fuse is blown.

if it is the ecm b fuse thats blowing i would try disconnecting your oil sending unit and see if it still blows the fuse.i have seen the sending unit short out internally before and blow the fuse.if it is the ecm 1 fuse it is either a chaffed wire or one of your injectors shorted.

I have a lhs 1996 Chrysler. The car wont start and the engine fuze burns out.


I also have a 96 LHS that randomly blows the 20 amp ECM fuse. If this is what you are referring to, the problem may be in one of your ECM sensors. 1-Start by unplugging all ECM sensors (Temp, Cam, Crank, 2-O2, TPS, etc.) and replace the fuse. 2-Crank the starter (the car will not start) and see if the fuse blows. If it does you probably have an electrical problem with the ECM. 2-If the fuse does not blow, plug in only the cam sensor and start the car; it will idle rough and the check engine light will come on. If the fuse blows, the problem is the cam sensor or wiring to it. 3-Continue plugging in sensors one at a time and try starting. When the fuse blows, you will know which sensor and/or wiring to the sensor to check. This process of elimination has worked twice for me.

Keep blowing ECM fuse on 90 honda accord


I'm thinking the ECM is bad and grounding out, causing the car to blow the fuse. The old gas wouldn't cause this problem.

Suspect fuel pump may be causing too much draw, it's on same circuit I believe. Have draw tested, or at least check & clean all connections at fuel pump and try, if that fails, replacing fuel filter to reduce possible load on fuel pump may help also.
