After my cam install I have to push my gas pedal to the floor while cranking it over in order for it to start. Any ideas why? I have larger injectors I could put in. I also have not sent the PCM out for a tune but would either of those things cause the car to not start? After I get it started it doesn't want to rev up.

Any suggestions would be appreciated. Car and motor only has 30k on the clock.

 

Get it programmed. That should fix it.
Also make sure your valve lash is set correctly.

 

Putting the pedal to the floor while cranking it puts it in "clear flood mode".... actually reduces the amount of fuel that is injected for startup.
