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.

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.

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.

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.

2004 Chevy Trailblazer LT w/inline 6cyl cranks but won't start. Fuse #28PCM-1blows when ign is turned to ON. Do you have a wiring diagram for this circuit? Thank you.Bob


This fuse powers the injectors. You may have a shorted injector but usually this is caused by the pink wire touching a hot engine and melting the insulation--causing a short. First trace the pink wire from the injectors to the fuse box inspecting for damage. Also trace it to the pcm. If no damage, disconnect all injectors and put in a fresh fuse. Turn the ignition on and check the fuse. If it burned, the wire is still shorted and you can assume the injectors are ok. The short could be in the pcm. You can cut the pink wire to the pcm and put in another fuse. If it burns again, you definitely have a short along the wire. If it doesn't, the pcm is bad. Repair the wire with sloder and electrical tape.
If the fuse did not burn the first time, turn thr ignition on and plug the injector in one at a time, checking the fuse after each one to see which one is shorted.

I have a 94 Buick centry and the ecm fuse keeps blowing out. New battery and starter. What would cause it to happen


A short in the ECM , does it blow the fuse right away ? or does the vehicle start then it blows the fuse ?A short in the wiring going to the ECM could do it also ! Disconnect the connector at the ECM Pull the fuse an check the wire with a ohm meter ! starter has nothing to do with, has a short to ground somewhere on that ECM power feed circuit .You need to find a wiring diagram for that circuit. Connector 2 black 24 pin connector , A-2 pink wire . first you need to find correct side of the fuse pin without power , with volt meter , one side will battery voltage ,you don't want that one ! put black lead to ground an the other to the wire an see if there is continuity. Hope this isn't to long winded an I hope it helps !

2003 chevy silverado injector 2 fuse blows when ignition is turned on


You ohmed them but did you check them for continuity to GROUND, to find out if one of them is grounded out ! They normally ground to ecm/pcm not to eng. so check them for short to grd with wire harness unplugged from all injectors and check 1 at a time, If they all show open...no ground then check your power should be pink for chafing or bare short to ground. this will be on Bank 2 you are checking which is the Head that setsfarthest back to firewall. Bank 1 is Head farthest to front towards Radiator.

Put a new motor in my 1990gmc truck 1990year.It ws a 10 amp fuse for the ignition, what is wrong/blo


Hello! Just because you changed an engine does not mean that something unrelated hasn't occurred... In the fuse box is the 10A fuse in the far left row...Third fuse down?....If it is that is the ECM ignition Fuse...Tracing from the ignition switch it is a Pink wire that goes to a 3A in-line fuse and changes color to Purple/White then on to the ECM...When the fuse blows is there battery on the Pink wire?...If not...Pull the blown fuse...Disconnect the main Battery terminal...Set multimeter to the X 10 scale...Place one lead on each side of the pulled fuse socket and the other lead to bare metal ground...Does either side read resistance to ground?...If it does turn the ignition key from off...To ACC,.. to start and finally hold on run...Does the ground go away in any of those positions? if it does I would suspect one of the ignition switch wires is touching ground...Hard to find...But if you alligator clip the meter in place and wiggle the ignition wires you may see it come and go...Indicating where you are moving the harness the bare wire is pinched to ground...
However...If the movement of the key does not produce a change...Remove the fuse box...Flip it over... identify the wire on the fuse that blows and trace it with meter in-place wiggling as you move through the harness until you find the bare spot touching ground...

An easier softer way is to identify the color of the wire that connects to the ECM IGN FUSE...It will be Red, or Purple/White and go to the ignition switch...Cut it on both ends and run a wire of the same gauge from point to point...Guru...Saailer

I have been having issues with my 1996 Jimmy. When I turn the Key to accessory, the #10 ecm ignition fuse blowes. It will not start. Any suggestions? Thank you.


Unplug the injectors, coil, crankshaft position sensor, and the ignition module. Check to see if the fuse blows with these unplugged. If it doesn't than plug these back in one at a time until the fuse blows and replace that component.

If it still blows. than the pink wire that supplies power to all of the above components is shorted. A careful inspection of the wiring will be necessarry to find the problem.

One other note that fuse also feeds the Vehicle Control Module on vehicle equipped with a VCM (4.3 liter)

Ecmb fuse blows as soon as i put in a fuse without keys in the ing.


hi, i have seen this problem before, i am a trained ase mechanic who works in a shop weekly. in my case, the suburban was a 91, it started by blowing the fuse randomly, then as it got further along, the ecm b fuse would blow consistantly as you describe. I found the problem to be in the wiring harness between the fuse block and the electronic control module on the pink/black power wire. It had become hot next to the radio and the insulation had melted into a direct ground to the ecm. then as time passed, it melted six other wires till it hit battery power. this is when it shorted the fuse all the time with key in or out. You should start by checking behind the glove box at the wiring harness going into the ecm, if you can get a schematic for the wiring, it would be better advised. See if you can find the Pink and black stripe wires(there maybe several of them as they power everything from egr solenoid to oxygen sensor possibly) and look for melting of the insulation. If you do find this to be the case, technically you should replace the whole harness, but it is possible the cut and splice in new wires. If any other wires are affected, you should replace these also. Check the whole length of the affected wires, they may have shorted all the way up or down. If this sounds like a big deal, it is! so, good luck, hope this helps.

I have a 1995 gmc sierra 4x4. It blows transmission fuses. When i unplug the wiring harnes from the transmission it stops blowing fuses. Is the short in the trans or in the harness? How do you tell?


The short is inside the trans, but you will need to take the pan off and trace each wire to find out where the short actually is. You have narrowed it down pretty well. One way to really narrow it down before you take the trans out is to unplug the connector and put battery power to the PINK wire cavity. Now take a jumper wire with a 10 amp fuse and touch each wire until the fuse blows. The TAN/BLACK is the Torque Converter Clutch solenoid. BROWN is the 2/3 shift solenoid. Lt. Green is Shift Solenoid "A" and YELLOW/BLACK is Shift Solenoid "B". Those 4 solenoids are powered by the Trans Fuse.
