My 99 suburban Ecm-1 fuse keep blowing
you may have a possible short on the wire supplying power to the ECM or any actuators and/or its circuit that is short and feeds on power through the ECM-1 fuse. When does the fuse blow? for instance when you initially turn the ignition switch to on, or during cranking or while the engine has already starting and running.
i have a 97 suburban that on vacation i blew 2 ecm fuses(while driving) and when i reached destination i hit a speed bump and everything went out, not the fuse, would not restart after that....the camshaft position sensor and the pickup coil have been replaced but still not starting
having the same problem it happens when I turn the ingnition on, no starting needed
I am having the same problem with my 99 gmc suburban. As soon i turn the ignition switch the fuse blows. I dont even have time to try to crank my sub. just have to turn it enough to on and the fuse blows every time. Any suggestions?
mmmmmm try checking all grounds are tight and clean. Try auto zone or a haynes manual and see if there is any info on injector resistance, and coil/ dist resistances etc.. some sesnor is probalby drawing way to much! Also check the wireing for shorts especially where is passes through tight spaces and were it is close to moving parts or exhaust. I wouls suspect that it may have blown your computer? Good luck
ecm power wires on passenger side of engine ground out to the exhaust, pull awasy, and check for damage, my 97 kept popping fuses, and this fixed it
I have a 2002 tahoe. Blew the ecm1 fuse. I replaced it it started right up. Untill I put it in drive then it blew the fuse again. It did this about 5 times. Then it started blowing the fuse as soon as I turned on the key. I tried about 20 fuses it kept doing it. So I left it for the night went back in the morning and put a fuse in it started right up and has been good for two days. I am planing a long trip and don't trust it. Any ideas where to start. To find what the problem might have been. Thanks
