2G Faulty ECU causing hard starts?

[BENJAMINSTACKS_TSI]

Been having hard starts since I bought my 2g. Could a bad ECU be causing this problem?

Recently I had all my maintenance done, OEM timing belt, balance shaft belt, accessory belts, OEM crank sensor, OEM crank pulley, OEM CTS, etc, and this problem with hard starts still occur. Starts up fine then will have a hard time starting,
then wait a couple minutes then it starts.

Sounds like a battery ground issue, or chassis ground problem

It could be a number of different things. If you just replaced the coolant temp sensor and this didn't happen before, I'd double check to make sure it's working properly the wiring and plug are in good shape. Might want to fill out a profile too.

does it stumble for a few sec then eventually clear up and idle fine?

yes it does this and it idles fine once started,new battery and clean terminals

Does it happen after the car has been sitting for a while? If so you might want to check your coolant temperature sensor.

Coolant temp sensor has been replaced with a new oem one also

After it sits for awhile pull the plugs. If one of them is wet and/or smells of gas you have a leaky injector in that cylinder. The car will stumble until fuel ptessure comes up and all the gas in that one cylinder is purged. Likely once its idling shut it off and it starts again cleanly until it sits again. This is one possible scenario.

What year is the car, does it have a cam sensor and crank sensor or just one? Who did the timing belt
