Two problems not sure they're connected while driving all gauges can just die and come on whenever doesn't affect driving also sometimes when I go to start it I can hear the fuel pump kick in for a split second not the two seconds that it should be running for and I try to start the gauges are not working and it will not start you can shake the truck hit things sometimes it will start please help

 

The way you describe the action suggest a loss of ground for the dash or loss of power to the dash.
1. If the Dash goes dead while driving but the motor stays running. ' After' starting, the dash has no effect on the motor running.
2. The motor will not start when the dash is out because ...now... the PATS is out as well so the motor will not start and the fuel pump may not run. This is a normal effect as designed for theft protection.
Good luck.

 

Thx I totally agree from all the searching I did but I didn't find much on where the PATS system is or what I can do with it it is a 2001 with 5.4 over 500k for sure but odometer went out 5 yrs ago

 

Not to be fallacious, but letting things go has now caught up with you.
There now may be more than one issue present.
Only way is to make repairs.
The speedo functions likely are an issue on the dash circuit board.
The display is driven by a micro processor that gets its info from the engine computer.
The PATS is a stand alone and does not depend on the dash.
That's why you been getting away with it.
Now that there is a power issue that affects both, games are over.
Good luck.

 

I'd like to think I have not let things go have fixed too many things to list we have obd2 reader and fix problems as they come but no code has been given on this problem when gauges work no engine light on but I know it works all lights flash on when starting when it works stand alone pats system where is it can I check connections clean or replace it

 

The dash and Pats are not part of the OBDII system so you won't see any codes related to them using a Scanner or Reader.
When the dash is working, access to dash HEC diagnostics are possible for some faults and reading for various functions in the Dash system..
For this you need the HEC Documentation to interpret the displayed data that is in several formats.
Good luck.
