04 Explorer RS Problem

I have installed a Valet 562T with a 556UW in a 04 Explorer. Everything seems to be working but it doesn't always remote start. What happens sometimes is when the RS is activated the parking lights flash, ignition and accessory come on and that is it, the starter doesn't even try to crank. again it works 7/10 times. I verified my connections and haven't found anything wrong. Here is what i followed incase anyone sees a problem: 12 VOLT CONSTANT YELLOW (+) IGNITION SWITCH HARNESS STARTER RED (+) IGNITION SWITCH HARNESS IGNITION 1 RED / LIGHT GREEN (+) IGNITION SWITCH HARNESS ACCESSORY /HEATER BLOWER 1 DARK GREEN/ LIGHT GREEN (+) IGNITION SWITCH HARNESS and i have the Blue from the 556 to the Blue/White(2nd Status) on the 562T. I've installed a couple of these systems and haven't ran into this problem before. Thanks

When it does this is the theft light flashing sometimes when its realy cold the ford keys send out differant signal. Your supposed to be able to freeze the key thats in the box then relearn it to the car. 

I don't think the theft light was flashing but i will double check this. This also happened when I had it in the garage and everything was at room temperature(62F). I will try it in the morning after it's been sitting all night in the cold. Or should I be using the Blue(Status Output)instead of the Blue/white

If the theft lights not flashing then its not the bypass. Is it set for tach or voltage.

Also make sure you have the purple rs wire connected to the starter side of the start wire and the green to the key side.

I verified that the purple and green are hooked up correctly. I am using voltage sense. yea when RS is activated the instrument cluster comes on as if you would turn the key to the on position and it doesn't even try to crank. The theft light comes on then goes off as normal. acts just like if the key was being used.

Have you verified that the RS puts +12V to the starter wire when it's supposed to? Maybe there is a bad relay or something inside the unit itself. Or maybe said wire is not a solid connnection to vehicle side of starter wire?  Check for a good solid ground while you're at it.  Intermittent problems may indicate a bad connection somewhere.Keith

Your problem is right here! The PATS is not being bypass when you are doing the remote start. Get the bypass working first before proceeding any further. Other wise you are wasting your time. If the vehicle is able to crank than the bypass is successful. Once it's cranking, now you can look else where to see if any other connection you may have miss or done incorrectly.       Be careful whose advice you buy, but be patient with those who supply it.

It does crank and start sometimes. Also I can have the key in the ignition and it will not crank with the RS. I will verify my connections to the 556UW. I am using Red(+12), Black(Gnd) and Blue(activation). Does it matter if I use the Blue or the Blue/White off the 562T? They are both status outputs according to the manual.
