Hey guys. I have a Sniper tuner and my CEL is on. The Sniper can't read the PCM it says...any ideas?? Now a few weeks ago, my CEL came on, went to autozone and there tuner said I had no power to my OBDII. So I looked for the blown fuse...found it replaced it, took it back down there and the code was a bad fuel sending unit. I have yet to replace it though. I have checked the PCM fuse again and it is good. What would meke that fuse blow in the first place. I beleive it's fuse #41. And it's also idleing really low and even shuts down and red lights now.....I have no idea whats goin on......Thanks for any help!

I'm sorry...It's a 2004 F150 New body style with a 4.6

I do not have experience with the Sniper software but I do with several other tuners. Is the software and firmware up to date for the unit? This hads cased complications for some SCT and other devices.

What Sniper unit do you have as well?
Commando or Special forces?

I have the Sniper Special Forces Tuner. I found that my sniper will let me tune the truck but will not read trouble codes the recon wont work on the truck because its a PPC computer , Recon only works on the EEC-V computer. Went to Auto Zone and the CEL code is the Idle Air Control reading low speed, hence the idle is going wacko. So Do I need a new IAC or should I try cleaning it? Thanks again for all the help
