Need more details on pumping to much fuel?

Is fuel pouring out bottom of injector key on engine cranking or just key on or off?

Any code setting or check engine lights?

Will it start if you hold pedal to floor?

Does it have good hot blue spark to all plugs?
Are plugs black on ends?
Black smoke out tail pipe?
Will it go ahead and start or do you have a no start?

Map sensor and tempt sensor to PCM and TPS sensor play a very important part on fuel mix.
Do you have a scaner to get any sensor readings in PCM?
