obd port not working

[michael b]

My check engine light came on & I hooked up my tester in the OBD port to check for codes but nothing comes on. My SCT tuner wont power up nor will my superchip tuner for Ford codes

I had a remote starter/keyless entry installed 2 days ago & I believe there is a purple wire hooked up to the computer area under the hood on the firewall Hmmmmm

Any Ideas?

Thanks

BTW The problem with the trac is that the "check engine" light is on & when the truck first starts it stumbles & dies Then I restart & it stumbles a bit & then the idle gets a little high, Then it stabilizes. This happened last year when it got coldish outside & the shop fixed a intake leak (300.00) It feels kind of the same but when I checked the codes a couple weeks ago they were different then last time that I had the problem.

Codes #1131

> & 1151-- 1131 is:Lack of H02S11 Switch-Sensor indicates lean.

> 1151 is: Lack of H02S21-Sensor indicates lean.

usually when the obd II plug is not working there is a blown fuse.

Yes, The diag port fuse is blown.... OR the wire they tapped into is now broken...

Jeebus, I just finished diagnosing that my headlamp switch is shorting the #11 fuse, when the DC adapter for my mp3 player falls apart in the cigar lighter, and blows the 20 amp fuse for the cigar lighter and diagnostic port.



It reset my damn scanguage. lousy piece of crap. :angry:



I'M HAVING A BAD FUSE WEEKEND.
