All good answers above. You might also try the lock out safety function. The car must be in Park (maybe neutral) before it will crank. With the key held in "start" position try jiggling the shift lever back and forth fairly hard while in Park. Foot on the brake. Other than this, consider paying a mechanic to run a full diagnostic test. It will cost you, but not as much as the battery and starter. I agree that batteries and alternators have been faulty right out of the box so have them checked. Also you will find on the Web some sites where for a small fee you are connected with a mechanic who specializes in your brand of car. My wife's BMW had an issue in the drivetrain that the dealer could not figure out. I found a site for BMW mechanics, paid something like $35-45 and had a correct diagnosis in minutes. Be careful that you do not sign up for a monthly "service", just a one time deal. DId you or a friend put in the battery and alternator? If you paid a mechanic he should have got the car running one way...

Odd as it may sound it is not unheard of to have a "new" battery and/or alternator to be defective, so these should be checked. Also recheck all wires and cables involved to be sure they are connected tightly and properly. Not sure if your OBD port will send data if engine isn't running but could be worth a try. Also, hit the starter with a hammer a few times. Seriously. If you have a solenoid on the starter it should be double checked. Previous answer is best place to start.

I found that if the machine has sat for a while (years in my case) just using the steam wand WILL NOT WORK. I followed the suggestion of forcing water into the pick up tube that sucks out of the water tank. I used one of those injectors (like a big hypodermic) for flavoring meat. Worked right away and I’m pulling pretty good shots already. Good thing since my Rancilio Sylvia just bit the dust after 20+ years. Got the Starbucks machine a long time ago at a thrift store for $50.00. Oh did I mention it was virtually brand new? Thank you IFIXIT people!

Follow up to "Mark" Our cups seem to be under pressure, not vacuum, possibly due to altitude (over 5k ft). I push them down so the needle punctures the bottom, then repeat after turning the cup until there are 6-8 holes in the bottom. Also have better luck with the plastic k-cup you fill yourself. Before this my brand new machine was clogging and short cycling starting with the second cup!
