I have a 2010 Chevrolet HHR 2.2L it cranks but won’t start I done changed the fuel pump starter ignition coils spark plugs the fuel injectors the crank shaft and cam shaft sensors what else would stop it from starting we even sprayed starter fluid still no start it has fire and fuel but still just turns over but won’t start

 

How about some details? Did this happen out of the blue? Was the check engine light on for weeks? Did anybody do work on the car immediately before?
Did you look at the timing chain?

 

A friend of mine gave it to me after he put bad gas in it and all that we changed on it was what we found wrong oh and we did cleaned out the fuel tank and no we didn’t check the timing chain yet cause I’m hoping it’s not that

 

You've spent a good chunk of money replacing parts. Checking the timing chain is pretty close to free. Pull the valve cover and have a look. The chain should not have any looseness at all.

Also get a code reader and see what diagnostic codes are present. Post them up here, just the alphanumeric codes, ignore the descriptions, as they are often misleading.

 

Ok I’ll do that tomorrow morning thanks

 

What is "bad gas" that ruins a car? Do you mean diesel fuel?
Another basic free test is a compression test. Most auto parts stores will "lend" a compression test kit, you pay for it then get a refund when you return it.
If it ran diesel there isn't much hope.

 

No it wasn’t diesel it was some dirty old gas he had put in it but we cleaned the tank

 

"bad gas" + "tank cleaning" = sand or flakes in gasoline (probably)...
If so, look for anything that could be blocked by the flakes. Most likely injectors.

 

The fuel injectors were replaced.

 

yes the fuel injectors were replaced.
