SOURCE: 20 amp ECM B fuse

check again the fuel pump. check the resistance if too low. or unplug the pump and put a fuse again, if the fuse will not blow, then the pump went bad again.

SOURCE: engine 1 fuse keeps blowing when you turn the key

Engine 1 fuse powers the computer and some sensors. I had this same problem on a 98 chevy van 3500 and found the wire going to one of the oxygen sensors had shorted out on the heat shield. Inspect the wires going to all of the oxygen sensors. On this van one of the oxygen sensors on the driverside the wire was laying on the heat shield which eventually rubbed through the wire and shorted it out blowing the fuse. Your short could be on a different sensor but check all of the oxygen sensors because the wire runs so close to the sharp heat shield.

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.

1997 GMC Sierra, I keep blowing the ECM 1 fuse, I replaced Fuel Pump relay and Fuel Filter. Does the ECM 1 Fuse Pump the Fuel Pump, also disconnected the Fiter turned on the key and no fuel.


ecm1 is injectors not fuel pump ecm-b is fuel pump its more likely to be a faulty relay for the injectors, it would be a similiar design to this
12900_oil_sending_unit_and_fuel_pump_circuit_80-yoo05im5qhid2i2poe1uh03c-5-0.gif this is for the fuel system, relay for the injector is nearly the same.

Why does my efi fuse keeps popping 1999 chevy prizm


Pull the EFI relay, replace the fuse, and see if it blows when you turn the key on. If it does not turn the key off, reinstall the EFI relay and remove the circuit opening relay/fuel pump relay. Turn the key on. If the fuse blows than we know the problem is One of the O2 sensors, the IAC, the purge solenoid, or the ECM You can unplug the O2 sensors, iac, and purge solenoid. Replace the fuse, turn the key on, and plug them in one at a time until the fuse blows. Replace that component. If the fuse blows with those unplugged than its probaly the wiring and possibly the ECM. let me know what you find and I'll help you more if needed.

1987 Chevy silverado gauge / idle fuse keeps blowing


The 20amp ga/idle fuse powers a hot fuel module which powers the oil pressure switch, the fuel pump relay, and the fuel gauge in the tank.
Any of the four components including the fuel pump can blow the fuse.

The key is to find out what is causing the ECM fuse to always blow. With just the key on try and see if any codes are set in the ECM. If not, try a new ECM. If the fuse still blows, then disconnect all accessible electrical for everything, including radios, accessories, relay boxes,etc. except the ECM. If the fuse still blows, then probably something wrong with the wiring to the ECM. If it doesn't blow then start hooking up things one at a time until it blows again. Once it blows, that is your problem.

Well you have a short and still have to narrow it down.
How difficult that is depends on what attaches to that fuse.
If it is just the ecm, then disconnect that and see if the fuse still blows?
(if you want to stop wasting fuses, you can just use a test light in its place.
If you have a short, the 12 volt light will be bright. If things are normal, then the 12 volt light will be dim because in series it will only be getting 6 volts.)
If removing the ecm stops the fuses from blowing, then take it in and have it tested.

ECM BATT fuse keeps blowing


That fuse provides power for the fuel pump. Either your fuel pump is blowing the fuse or there is a shorted wire.
