Before you jump any relays take pictures of the area. Wide angle first, then close up.I bought a multimeter so if someone could tell me exactly what wires to test, how and when (key on or off) that would be great. I also bought a fuel pressure gauge and made a jumper wire. Based on what I’m reading I should jump fuel pump relay K3 at terminals 30 and 87 making sure to touch the two silver parts. What should I do if it cranks? Immediately remove the wire? If it doesn’t what would the next step be? Thank you
My carsoft scanner does have a live data function. Doesn’t the engine have to be running to get live data?
Yes everything is connected as it should be. Radio Alarm LED blinks once to indicate key is being recognized. Vehicle cranks but won’t start. I will check live data feed.No, engine does not have to be running to look at live data.
Have you sorted issue with fuel feed?
I have 3/8 fuel in the tank, I cranked the engine a few times and pressed the Schrader valve to let air out while having someone else crank the engine. Fuel pressure shows up as 0.How much fuel is in tank?
You are going nowhere until you remove the air trapped in the fuel line. Have you connected the fuel pressure gauge?
Only important values are 196 and 199.As recommended by Witek_M here are the results of the engine live data for driver authorization. 199 Immobilizer shows NOT ACTIVE. 197 Status of drive authorization as immobilizer is activated. Does this mean something is wrong with the immobilizer? What exactly is the immobilizer is that the coil ring that goes around the key hole with the two wires and box that clip onto the steering wheel? Thank You

Very good. Repeat this procedure until fuel comes out of the Schrader valve.I have 3/8 fuel in the tank, I cranked the engine a few times and pressed the Schrader valve to let air out while having someone else crank the engine.
Wouldn’t that kill the starter if I continue doing it? Installation of fuel pump filter and lines are correct, everything is right and pump isn’t making any noise. It is a new pump and not a cheap one.Very good. Repeat this procedure until fuel comes out of the Schrader valve.
The immobilizer is fine. Forget about it.
If you aren’t winning, check the installation of the fuel pump, fuel filter and lines. Something isn’t correct. Is the pump running? Is the fuel line pinched somewhere?
