all eight cylinders are showing that they are missing, I've changed coils, plugs, and fuel injectors. Also changed maf sensor stoll getting same results. Any suggestions?

 

First job.

Read the codes.

My Carsoft scanner works great,has identified precisely faulty parking sensor, coil and injector.

If all cylinders were missing it was very unlkely to be all eight coils plugs or injectors.

 

@Alvin Watson, how many kilometres/miles on the vehicle?

Has any work recently been done to the engine or inlet manifold areas?

What DTCs are in the system?

What are STFTs and LTFTs?

What is the battery voltage across the terminals with the ignition in the OFF position when measured with a voltmeter?

What is the fuel pressure at start up, at idle and at WOT?

 

Ask yourself what is common to all eight cylinders to run?
Fuel, fire, with air being the third, but that's ruled out.
As others have asked already what's the fuel pressure???
