Thanks for taking the time to look. I have a 99 a4 1.8tqm. It turns over but will not start. Right now it has the "injector open circuit" codes for all four cylinders(p1237-1240). I've cleared the codes but they come back immediately. I've put some new parts on the car in the few months I've had it which I'll list below to eliminate some things.

New Parts
-fuel pump relay
-ignition switch
-icm
-engine speed sensor/cps

Also, the timing belt is good as well as the fuel pump and filter. I do have fuel pessure at the rail. All the fuses are good as well. I'm assuming the codes would indicate the injectors are not squirting fuel. Are there any things/areas to look at that would cause this for all cylinders all of a sudden? Any advice would be greatly appreciated! Has anyone been through this nonsense?!

 

If it's on all four you have a bad ground.
