Hi all, need some help to figure out what I need to check to determine why this start issue has appeared. Since I have never had any start issues before.
So the full history is this; Car hadn’t been driven much during this past 2 years due to Covid/lockdowns. Took it out for a spine and the engine light came on and there was engine wobble. Turns out one of the spark plugs were broken. Got all 4 replaced, also replaced the coils since they had some wear on them. Got it serviced, so engine oil and filter and air filter changed. No issues so far, car still started fine.
Then I got the fuel injectors cleaned since I never had them cleaned (car is almost 200Km). I could see some carbon build up on the pistons area so put some fuel additive (liqui moly, Fuel System Cleaner/Conditioner). After that I started having starting issues. I turn the key and the engine cranks but doesn’t start, so I now I have to crank it a few times before it catches and tend to hit the gas petal to get it to catch before I can drive.
I looked to see if there was any fuel leak or disconnections around the fuel rail/injectors but nothing. checked all the other areas that was recently changed but nothing.
Not sure if this is due to the fuel additive so been driving a lot to use up the fuel, got it down to 1/4 and filled it up again but still having starting issues.
Please let me know if anything comes to mind regarding this start issue, not sure what to look at next to figure this out. Thanks.
