I did an ultrasonic cleaning on Injectors and after that I have a hard starting of like 5 or 6 seconds, the thing is that in the first try in the morning it works correctly, and even works after some seconds after the motor was turned off, but when the car is turned off and waited 20 min or more, I hace the hard starting.
I think you should buy repair manual first for your vehicle after that it will be easy for you to solve the problem. Check the link may be you will find something useful here

disconnect the batt. is your fuel pump running check fuse listen for it
SOURCE: 2006 HHR turns over fine but won't start
Turn your key to the "on" position and listen...you should be able to hear the fuel pump running. If not, I would like to say to check a relay, but the hard starting was probably an indication that the pump was going bad and it most likely went. If the pump is running, I would replace the fuel filter or get a fuel pressure test at the fuel rail. Hope this helped, sorry for your troubles, and I hope you find a resolution to your problem that is not too painful.

replace the floor shifter. there is a switch on the shifter that allows the key to move. gm has had alot of problems with these shifters.
Most of us know
how the injectors get clogged. Its nothing else but the fuel that we use which
causes clogging. Every time we turn off our car's engine, last drop of petrol dries
on the nozzle of the injector and leaves behind deposits. These deposits become
firm with the heat of the chamber. The more we drive our car, more deposits
accumulate. Gradually it starts to restrict the flow of petrol from the tiny
hole on the nozzle and the injector starts to lose its efficiency. This causes
the engine to lean misfire and hesitate on different rpm, power and pickup is
lost, the car becomes uneconomical on petrol, unburnt fuel can be noticed in
the emission and worst of all the wear of engine becomes faster. Only 8% to 10
% clogging in the nozzle can cause all this
Proper cleaning can restore their like-new performance. There is no need to replace fuel injectors unless they are actually gone bad. Injectors are designed in such a way that they are not very convenient to clean. They are sealed units and cannot be opened for cleaning. Ultrasonic cleaning is MOST effective process for cleaning fuel injectors. It is cheap and comprehensive solution for the problem.
Under certain conditions customers may experience a MIL "ON" condition with DTC P1349 indicating a variable valve timing (VVTi) malfunction. In some cases, the cause of this DTC may be the VVTi actuator.
In general P1349 is a misfire or ignition issue under most general OBD-II - but Toyota spec'd OBD-II has it as a VVT malfunction. Unfortunantly - hard to tell which it is. Might be the ignition timing set too advanced (VVT-i issue) or low fuel pressure (bad or clogged injector, bad or low flowing fuel pump/regulator). An emissions test could tell you which one it is. If you want to try a quick fix on your own, I'd start with the basics, change the spark plugs, air filter, and maybe the pcv valve, all these are cheap and easy. Other things could cause the problem though, so if the quick fixes don't work, I'd lean toward the injectors.
Seafoam and other additives are very good solvents that can help clean the injectors - but may not be strong enough to clean off these injectors. Injector cleaning services generally don't work that well - best way is to have these cleaned ultrasonically or replaced (very costly).
