Ok so it's a 06' Lexus GS 300 with 288xxx I had a code for bad knock sensors although the car was running fine I wanted the light to shut off so I had the sensors installed... During installation 4 of the 6 fuel injectors broke. I got new ones and had those installed as well. Now the car is put back together but won't turn over. It's very close but she just won't fire. We've been over it twice now and can't see anything wrong. It's like it's not getting gas or maybe no spark. We've been through all the fuses and they're good. It's got gas in it as well I just don't know... Maybe air in the fuel lines? What do you recommend I do?
