Check if the injectors are leaking and also test the O2 sensor.

Turn the key On-It'll be very obvious if its leaking

. Ok then the injectors definately arnt leaking. I just replaced the oxygen sensor and its still spraying way too much fuel out of the injectors. It wont even start because its getting so much gas. Can the injectors be bad even tho there spraying exactly the same. Thanks hopefully that helps

It suppose to be spraying in a mist cone shape pattern-not breaking up/puddles

. Yea there definately spraying not misting. So does that mean my injectors are bad or does it have to do with something else

Could also be the fuel pressure regulator leaking too-also test the coolant temperature sensor.

The fuel pressure reg. Is new I had a mechanic install it and I put a cooliant temp sensor in a couple days before the o2 sensor.

Check the fuel pressure if its within 9-13psi this is the specs

. Ok cool I will test the psi. If it is more then 9-13 psi how do I lower it. Or how do I fix that problem
