If you have a scan tool or code reader, you shouldn't be disconnecting the battery to erase codes, just use the tool.
Now, does the fuel pump run when you first turn the key to run? Do the check engine and security lights come on and then go out after 10 seconds?
Will the engine start for a few seconds with starting fluid?
Just 2-3 short shots into the throttle body then try to start. Just try it once. Let me know if it starts. if not check for spark, if it does start check the fuel injector fuse/s.
That would be fuse #1 in the fuse block behind left kick panel.
start with that first then.
check for spark
My way, make a test plug.
You can make a test plug with a new spark plug and some wire, a mini hose clamp and an alligator clip. First open the spark plug gap to around 0.075” and strip both ends of a 16 gauge wire about 4 foot in length. Attach the mini hose clamp around the threads of the spark plug cause that is a ground and secure it with the mini hose clamp with the bare wire end in between to make a good connection. Next, take the other end of wire and secure to an alligator clip.
Now, you have a test plug. Remove any spark plug boot you want and insert your test plug onto the spark plug wire end you just pulled off and ground the alligator clip. Lay the spark plug in some shade somewhere under that hood and then crank the engine and look for spark. It should crackle with sound and should be blue but red is ok, orange is a little weak. If it can jump that 0.075” gap you should have no problem igniting an engine.
You can also use that to check coils on some vehicles.
Now fuel, with engine off get a flash light and look down the fuel intake if you can and give the throttle a pump and look for gas squirting.
forget that last part , Now fuel, with engine off get a flash light and look down the fuel intake if you can and give the throttle a pump and look for gas squirting.
I made this paragraph years ago.
If you have a tachometer, then just see if it registers a cranking rpm. Then try the starting fluid.
