Hard starting after an ultrasonic injectors cleaning
Hi everyone,
I need some advice on this, I was having poor mpg on my HHR, so I take my injectors to a cleaning shop, they gave me the results and the injector were cleaned, well After I installed back the injectors I am having hard starting in some situations,
In the morning first starting it is OK,
After some driving then turning the car off and then turning on inmeddiatly is OK
the problem is when the car is off like an hour or more, then I have a hard starging of like a 5 or 6 seconds then it starts normally.
This is happening every day, and I have to say that before the injectors cleaning it was working ok, I have read in other threads that the fuel pump is the cause but, It was working ok. so I have no clue of what could it be.
Any idea ?
I appreciate anything
Thanks guys.

If you have an auto parts store nearby that can read trouble codes, have that done first. If any codes are found, post them here so we can give you an idea of what may be going on.
In the event that no trouble codes are stored, you csn try disconnecting the NEGATIVE battery cable for 30 minutes to reset the various computer modules to their factory defaults.
You may have the beginnings of a fuel pump failure, so having a mechanic check the fuel pressure might not be a bad idea.
Depending on how the injectors were handled, they may be damaged, so you should go back to that shop and have a talk with them.

Hi 843de / donbrew thanks for your quickly repply, I will try disconnecting the battery first, right now I have a message and a light on, it is because the TPMS in 1 tire is not detected, there is no any other message.
-donbrew I have no idea of what is this EGR tube, so I will make some review about and check.
about the TPMS, is there any battery in the TPMS or needs to be changed? wich one do you recommend to buy?
thanks for your help
