Hi,
I have 2012 Jeep Cherokee 3.7 V6 4x4, it has had a list of problems and now it doesn't run anymore.
Changed 2 ignition coils and spark plugs, turned out it needs a head gasket replacement, ordered the kit and had it replaced, also new thermostat (before that car was driven to another location)
Next the starter motor had blown up inside itself, replaced it and still no go.
And now changed valve cover.

The car starts only on 3 cylinders and dies about 20 seconds later. Out of ideas what to check for or what the problem might be.

Also tried teaching the key, no luck with that.

Hope maybe somebody has experience or knowledge what I could do about it.

Much appreciated, thank you!

A few guys here may have experience with your model Jeep, but you may also want to post on a forum where newer Jeeps are discussed. This is mostly an XJ (model) forum.

That said, how did you determine it was starting on 3 cylinders? (scanner or codes?). Has a recent compression test been done? Some ideas could be spark plugs, Variable timing, injectors, wiring, bad connector, intake manifold leak ..or a number of other things. I guess we just need to get some answers to start zeroing in on things.
