remote starter issues hornet 476t

I have a remote starter/security system Hornet 476T   FCC ID: EZSDEI475  2-66TH CODES

This is a four button fob with lock/unlock/aux/panic buttons  - that's it

In the vehicle there is a red led indicator light   a metal toggle switch, which I assume is a valet?   and a small push button.   

I'm having a problem now when I try to use the remote start function ( pressing the unlock & lock buttons )  the vehicle cycles, fuel pump buzzes and the truck starts and runs for about 5 seconds and then shuts off??   Not sure why it continues to shut down after 5 seconds?  

Everything else seems to work correctly, lock/unlock is good.   Just the remote start problem.   I have no manual and can't find anything on directed's website for this model. 

I have searched this post and see the 24 hour problems, but mine seems to be a 5 second problem  LOL

Sure would appreciate any help from the experts - I bought the vehicle used and this is the first time this has happend.   I'm guessing I pressed something I should not have or did something wrong when I programmed a new fob that I purchased.  I have two now and both work fine, the truck just doesn't run on it's own when I use the remote start option. 

Thansk much

There is a button you push and a metal toggle switch.  I am thinking the metal toggle switch is the valet because when I switch it - the remote does not work. 

Sorry for the vehicle omission.  Again, I'm only trying to diagnose why the remote start does not keep the engine running longer than 5 seconds.  

Thanks

Would you mind walking me through that procedure please?

Thanks

start the vehicle with the key

within 5 seconds press and HOLD the valet switch

the LED will light constant when the tach signal is learned

release the valet button

For anyone else searching this post for help -

The above instructions did no good whatsoever.  A bit-writer had to be used to reset the entire unit.  Took about 1/2 hour at the shop to do it. 

Everything is working fine now.   Thanks for the advice, I appreciate the efforts.  Good luck & happy holidays.
