Re: 2003 Astro injector flush

You're welcome. If the flush doesn't cure the problem, let us know and we can help you diagnose what's causing the problem. In the meantime you might want to check fuel pressure and leakdown, the results will tell if the fuel delivery system is working properly. Key ON, engine OFF, fuel pump running: Pressure must be 60psi to 66psi and must remain above 55psi for 10 minutes after the pump shuts off.
