Hi, I am Mike, welcome. I'm reviewing your question.

Expert:  Mike S. replied 9 months ago.

This website is not a scam.

Here are a few things that has to happen when you first turn the key to run, the check engine and security light come on and the fuel pump prime for about 2 seconds, then after 10 seconds or so, the check engine and security lights should go out, then turn the key to start and the starter should crank the engine over. Does all of this occur or do any of those check engine or security lights stay on or flash, does the fuel pump run and does the starter crank the engine over fast enough to start?

Is on theft mode
Expert:  Mike S. replied 9 months ago.

What? Say that again.

Expert:  Mike S. replied 9 months ago.

I gave you at least 3 things to check and you just say "is on theft mode", what does that mean?

Expert:  Mike S. replied 9 months ago.

Does all of this occur or do any of those check engine or security lights stay on or flash, does the fuel pump run and does the starter crank the engine over fast enough to start?

Expert:  Mike S. replied 9 months ago.

I assume you are saying the security or theft light is on, does it flash and does the fuel pump run and does the starter crank the engine over fast enough to start?

Expert:  Mike S. replied 9 months ago.

If you need a few minutes to go back outside and check, that is ok.

No communication to bcm the truck don't start at all yes fuel pump has power something happen when we try to connect the mic wire to the new radio
Expert:  Mike S. replied 9 months ago.

Ok, first of all you should have had the battery disconnected before replacing the radio, nonetheless, give me a second to get the wiring diagram and find out what to start testing.

Expert:  Mike S. replied 9 months ago.

Almost there, now is it 4wd or rwd and auto or manual transmission?

Customer: replied 9 months ago.
No 4x4 auto gas
Expert:  Mike S. replied 9 months ago.

Ok, when you turn the key to start, can you hear the starter relay in the underhood fuse block click? To be sure, remove that fuse box cover put your fingertips on that starter relay and have someone else turn the key to start and let me know if it clicks or not.

Customer: replied 9 months ago.
it doed
Expert:  Mike S. replied 9 months ago.

Ok, great, now using a voltmeter or 12 volt test light, let me know if the strtr fuse #62 has voltage to both sides of it when the key is on start.

Customer: replied 9 months ago.
it does
Expert:  Mike S. replied 9 months ago.

Ok, how much voltage or did you use a test light?

Expert:  Mike S. replied 9 months ago.

That fuse feeds power to the starter relay, so if the battery is fully charged and the starter wires are tight and there is 12 volts down at the purple wire on the starter solenoid, then either the starter is bad, or it's not grounding back to the battery.

Customer: replied 9 months ago.
I try it again tomorrow to send some more info I have to go for now
Expert:  Mike S. replied 9 months ago.

I am done, I gave my answer. I asked you how much voltage and you quit?

Customer: replied 9 months ago.
i use a test light we already check everthing you say from the begging i had to got do my job is not that quit on you i want my truck fix you think i pay for nothing just play around no sir am not ill contact you again
Expert:  Mike S. replied 9 months ago.

Make sure you check the grounds, too if the starter wires/cables are tight. Actually you should try to jump 12 volts right to the starter solenoid terminal.
