Okay. We are going to need to start with a little more info. The smoking really bad, was that from the engine or from the exhaust?

If that was coming from the engine then I suspect it was overheating and we may have a warped head. Can you get a recording of what the engine sounds like when you are trying to start it?

If this was from the exhaust then that would explain why you replaced the injectors.

So let's start with getting some basic info first. I would suggest with starting on getting the compression of the engine as I suspect we have some larger issues.

However, here is another guide that will help with no start issues:

Lastly if this was smoking from the exhaust and then you changed the injectors and now it will not start we need to check the fuel pressure as well.

Let's run through this info and let us know what you find and we can go from there. Thanks

Hello,

Just to clarify, previously you would have smoke coming out of the tailpipe? What color smoke did you get? (black/blue/white)
And it ran before the injector replacement.
What issue made you replace the fuel injectors?

It could have compression issue and not starting.

And currently it does not crank, right? Does it click?
Have you tried to jump start the vehicle?

Please let me know little bit more information.
Thank you.
