After replacing all of the fuel injectors my car will still not crank. I took the plug the loose and make sure that everything was clean put them back. Put the battery on charge and I and looked at the firing order it is correct and I still cannot get my car to start.

Hello,

When you turn on the key, can you hear the fuel pump come on?
An inoperative fuel pump could be due to a bad relay, wiring issue or a bad pump.

First check the fuel pump relay. It is located in the fuse box under the hood.
Check for any corrosion or burnt pin(s).

This relay can also be tested:

If the relay is functional, then check to see if there is power to the fuel pump harness.

If there is power but the pump is not working, then the issue is likely a bad fuel pump.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
