Hello, my name is***** your check engine light on? Has anything been replaced? Thanks.
Ok, give me a few minutes to look up wiring and I'll see what could cause the 20 amp IGN fuse to keep blowing out. Thanks
In what fuse box is this fuse?
I see you said under hood.
Here is diagram, let me know exactly what fuse your referring to. Thanks.
Does fuse blow right away or only when turning on key?
This fuse powers the fuel pump relay. It sounds like your fuel pump is shot causing fuse to blow. Remove fuel pump relay to see if fuse stops blowing, if so then this points more toward fuel pump. Then next step is to unplug the fuel pump to see if fuse stops blowing, if so replace fuel pump. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
No problem. Let me know how it turns out or if you run into questions. Thanks again and have a good evening!
