2005 Excursion 6.0 PSD w/ PATS anti-theft system.. I've posted this on other FTE Forums, so I'm taking the chance someone on one of the others will see this and have the answer.

Ok fellas, I'm about to start throwing tools, (not really, but I feel like it)..... Installed a Presitgue Remote Start (took out of wife's Blazer)..... Got in installed, and will remote start with key in proximity. Learned that I needed a PATS bypass.. Purchased a XPresskt model-PKFM.. Wired in as install said... now I can't get the (*&(^( thing to start.. engine just turns over until battery is drain or I shut down the remote start.

The only two things I can come up with is the negative input to the PKFM bypass isn't getting the negative amperage it needs to communicate or it's not programming to the keys. (followed key program instructions)( step 3 says to immediately start the veh w/ remote start, however it has the delay for the glow plugs to fire, not sure if it's taking too much time until start to finalize programming)(and the damn install directions don't say how many neg amps it takes to effectively communicate)

Not sure what to do next, really getting bent about the situation..

 

Did you resolve this?

I've installed a handful of RS's & can think of two things that would cause your situation but it's a stale post...

 

edit- nevermind

 

I apologize for not posting the cure for the encountered problem...

I returned to the shop where I purchased the by-pass module, they ran the wiring and couldn't locate an issue with the install. One of their techs said to install the PK-ALL module. He advised, for some unknown reason, some of the Fords will not communicate with the Ford designated module and the PK-ALL has more programs (frequencies) built into it and it will usually work.

He was correct, installed it, started just fine.
