Jeff Tourcotte, I am experiencing this same problem. I unhooked crank and cam sensor and still blow the fuses. Any chance you can email these diagrams to me seeing I can not get them to open?

SOURCE: my ecm 1 fuse blows

The diagram below shows everything that runs on that fuse. Check the wiring on these items for a short. If wiring is good, there is a simple way to see which item is shorting out. Unhook all the connectors (don't unhook the VCM) and put a fresh fuse in. Turn the key on--does the fuse still blow? If yes, there is a short in the wiring. If no, the short is in one of the items you unplugged. Now pulg them back one at a time with the key on. Check the fuse after each item until it is burned. Then you will know which part to replace. My first guess would be the coil. Let me know if you can't find any of these or if you have other questions.

I keep blowing the ems1 fuse in my 2010 Chevy aveo. My car turns over a couple times then blows the fuse. Help please?!?!


Might have a shorted circuit in the starting system. Good idea to also check for codes in the ECM. If any present, may help in pinpointing the problem.

Do you need to take the intake manifold off to check on why the fuel/ecm fuse keeps blowing in my 1994 chevy lumina


I would not think so
fuses blow from excess current draw after the fuse so check the wiring after the fuse for a dead short
check for relays after the fuse and if the fuse protects the pump , check the pump itself

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.

2003 chevy s10 ecm fuse keeps blowing what is the problem


Either the module itself is internally shorted, or the power wire to it off that fuse has a short-bare wire touching metal and blowing the fuse.
You will have to examine your wiring and try to find the short. Has any moisture collected in back of, or around the fuse box? If it is a bad wire, it could be bad anywhere from the battery to the ECM.
You might check with the dealer and see if the ECM can be tested for a short or malfunction, and if it can be done with it off the car or if it needs to be tested with it connected up. You may be able to run a new power wire from it's source to the fuse box and to the ECM. You sure need a wiring diagram for this. good luck.

95 chevy blazer keep blowing the ecm fuse


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.
