04 f150 lariat crank no start after installing a radio. Not sure if it could be a fuse, relay or if I fried something. Has happened to anyone before?

 

have you checked fuses ? This is why they tell you to disconnect the battery prior to working.

 

Battery was disconnected and all fuses were fine

 

You’ve probably done this, but go back and triple check everything that you had taken apart. Last time this came up, the guy had one of the battery cables fall out of place while disconnected, then didn’t get connected when putting battery back in.

 

Everything looked fine in leaving the radio unplugged for now, but its gotten worse I checked this morning and now my mileage isn't showing up.

 

so your truck starts/runs with stereo disconnected ?

when putting in new stereo, had you used one of the harness adaptors? In other words, when you now disconnect radio/harness, are you certain everything is now ‘back to stock’?

 

No it still hasn't started or cranked gonna take a look at it right now see what i can do or if I can do anything

 

….?

 

yeah I used a harness, and I just pulled out the pcm relay and popped it back in and it cranked over just didn't start, I tried putting in a different relay and I'm back to no crank. ( I did also put the same relay again and still no luck)
