Help!
I just installed 47lbs injectors on my car . I loaded the tune and everything now the car just cranks but it doesn’t start. Fuel relay was removed, cycled the car 5 times before and after installation. Mechanic is saying it might be the fuel pump but it was working/running before the install. I went back to 24lbs injectors and loaded the tune for that also but still no luck on turning on. Anyone know what else it might be ?

Are you getting any codes?

Why did you go to 47lb injectors? If you didn't add FI at the same time you don't need or benefit from that. What else have you done to the car?
