    Go back and have them check the timing for you, or they used the wrong heat range plugs. I would go to a different mechanic!

    Did you replace the plugs with exactly the same new plugs? Are the plugs gaped right? And did you put the  wires back on the same plugs? Did your turn the crank so that the number 1 cylinder is on top ready to fire?

    Maybe you put the spark plug wires back onto the wrong plugs. You will have to determine the firing order and check.

    See a mechanic again.  Check for any trouble codes.  Spark and fuel pressure needs to be checked.  Check if the correct spark plugs were installed.  Could be a bad crank sensor.

    take it back to who ever changed the plugs? does it run all right or is there more to this story? try turn the key on and off a few times before you try start it just to see if its a fuel pressure issue wrong plugs if it doesn't run well or drinking fuel.

    Pay for and see a car mechanic to look at your car.  Sometimes you can't CHEAP OUT.   Better than burning out a battery or starter motor.  It needs a tune up.

    The problem you though could be solved with a new set of spark plugs is still there and now it's worse. Pull OBD2 codes to get to *where* the problem is and diagnosed for the remedy.

      He never said the check engine light was on.  If it's not, there shouldn't be any codes.

    You can buy a cheap inline plug tester. That will show up a faulty plug. Check the gaps and make sure the HT leads are connected properly.

    Check the spark plug gap and make sure you have the right plugs!
