it turns over strong but no start. when i turn the key to start position no gauge or mileage reading till about a minute an then i get the dashes and the theft light blinking fast for around a minute and if i try to start every thing goes blank again. i changed the fuelpump and relay and checked fuses and tried spare key any suggestions would be appreciated . 5.4 liter, 230miles ,obd2 powers up ,links then goes to error

 

I'd have the battery tested first of all and inspect the battery cables and connections.

 

I charged the battery after killing it trying to get it started, cleaned the post. It turns strong.

 

A rapid flashing of the anti theft....is a strong indicator that the PATs system is having issues.

Are you loosing coolant or is musty smelling inside?....front window can leak over time and moisture migrates in and shorts out the PATS control module or the GEM module

 

never mind Reading comprehension error..

 

no coolant leak but it does have a slight musky smell, how do you test the pats control module

 

huh

 

This gets a bit involved and is not a simple relationship so keep an open mind.
First, a running engine that dies on the road is not caused by the PATS system.
Why, after starting, the PATS has no more control of the start process as it's normal Theft protection ends at that point.
.
Second, if the Theft lamp flashes, at restart, it tells us the PATS can't communicate with the PCM for some reason and detects it.
So this looks like two separate troubles and is blamed on Pats.
.
Turn the key to 'run' and wait a couple minutes to see if the Theft lamp flashes a two digit code that tells us it can't signal the PCM over common buss leads. Post the code for a check.
.
It's possible a PCM relay or a fuse powering the PCM has a problem.
The PATS knows this and 'complains' about it.
Good luck.
