Long time to start

Why did you remove the injectors in the first place? Were the same injectors re-used?

The dealer find one of the injector no good after clean it and still not working they recomend to replace all the injectors, about the same injectors reused, not sure, anyway they where changed and now the problem I posted still remains, Any idea?

Were the injector OEM replacements, if not this is your problem, we have used cheaper injectors in the shop and have had the exact same problem.

I agree with ken, the problem may be associated with cheap after market injectors try and get some clarification as to what was used and let us know.

Excuse my ignorance, what is OEM replacements?

Now I know what is OEM, Thank you, Now, if I run the Toyota with the cheap injectors for a while, and since BUY AUTO PARTS , the store I get the injectors, does not accept returns, once they are installed they considered used, So what will happen if I used them for a while, does this is going to make new problems, caused by running it with the cheap injectors, if I run it like that until I get the OEM?

Yep, you are in a pickle but lets run some tests first before we run out and get a new set of injectors. Remove the electrical connector from the injectors and the spark plugs, make sure the spark plug wires are not close to the spark plugs holes, and that no spark can occur in the engine bay, next crank the engine over while you watch the holes, you are looking for a heavy fuel vapor to come out of one or more of them signaling one or more of the injector are leaking, then you can take them back and tell them they are defective. Here also is a guide that can help you,
