I just changed the alternator this morning. Hook battery back up now cranks wont start no security light flashing no security light blinking at all. When turn ignition over gauges do not swipe don't remember if they normally did or not but now they do not swipe as in speedometer and RPMs. I've also been having trouble with the no windows no radio. Just driving down the road and radio cuts out and power windows hear a click under the dash radio coming back on Windows work again research and see if it's in the battery save circuit inside the dash cluster wondering if this is causing no start now. Any advice would be great!

 

32 views and not one comment LOL let me ask you this when you turn the key on an Excursion does the gauges for tachometer and speedometer do they sweep?

 

When does the security light on the cluster supposed to flash mine does not light up at all

 

The gauges do not sweep when the ignition is turned to the ON position. I am not sure on the PATS security light anymore. I can't remember how it used to blink before I went with the Gearhead Hydra chip....

 

So, basically you have power to your starter, but not your computer/injectors...

Something is likely unhooked/disconnected somewhere if all you did was change out the alternator.

 

I did the exhaust manifold stud change last month. Doing so I broke four bolts off recessed into the head and had to weld nuts on to them so I just connected negative battery terminal. After exhaust job was done but it all back together I tried to start and had the same trouble as doing now couldn't hear the fuel pump so drop the tank and switched it when to start back up still no start. I went out the next day to do more troubleshooting it started right up drove fine for the last month month-and-a-half no troubles till today when I disconnected the battery again.

 

Thank for information trying to rule stuff out.

 

Since you don't have any information listed in a sig, you have to tell us the specifics of your Ex otherwise we can't even begin to try and answer your question.
