New Fuel Filter - now car won't start

[aldissmith]

Hey..

Guys i have a problem i need your help please I just changed the fuel filter on my vehicle now it will not even turn over. No problem with the battery.

I could not find a similar post to the forum, so started this one. I have a lot of experience, so cannot understand how such a simple procedure could go so wrong. All connectors and hoses are reconnected as before. I did see a warning about knowing the "activation code" before disconnecting the battery if the car has an alarm; I did not disconnect the battery.

I just bought this car and have no real experience with its maintenance yet; can someone give me a hint here?

maybe these two problems are not related after all. getting the diagnostic check will be better.
