IF YOU HAVE CKED FOR A SHORT THEN MOST LIKELY YOU HAVE A BAD INJECTOR. YOU CAN UNPLUG ONE INJECTOR AT A TIME UNTIL IT STOPS BLOWING FUSES OR YOU CAN TAKE IT TO A REPUTABLE TECH WHO CAN HOOK IT UP TO A SCAN TOOL AND IT SHOULD SHOW THE BAD INJECTOR.

    First id like to say thanks for your immediate attn. earlier. Now the fuse is not blowing. None of the coils on the left rail are getting spark. Last night we cleaned all of the injectors and it worked great, we woke up in 10 degree weather(in case that matters) and we are running on 4 again. Sorry earlier i misunderstood a friend that is helping.... If you need any more info please let me know and once again, thanks

SOURCE: CHEVY 1500 TRUCK HEADLIGHTS TURN OFF WHEN YOU TURN ON SWITCH

If you have replaced the switch, and it is still doing it it sounds like you definately have a short somewhere in your wiring. On the other hand if the dimmer is in the turn signal arm ( forward bright back dim ) the problem could also be there in the dimmer switch, such as a short being caused by that dimmer switch being faulty.Auto Zone and Discount Auto Parts both test a lot of your electrical problems for free, and/or may have some knowledge to more accurately pin point the problem. Not sure about Pep Boys or some of the other discount auto part chains.

Check your cigarette lighter, it may be shorted. Also check all interior lights for bad bulbs. If not need to know how good you are at electrical work. Next steps can be tricky. Let me know.

Efi Fuse Keeps Blowing


It could be a short in the wiring, or a shorted injector possibly.
To check for a bad injector, pull off all injector connectors, put new fuse in, and turn key to on. Does fuse blow? If so, maybe a short in the wiring, possibly a problem in the ecu. If fuse is still good, put the injector connectors back on one at a time and watch the fuse. If one injector connector causes the fuse to blow, that could be a shorted injector. Good luck, don't know what else to check after that.
