sr will not start once it's been started in the morning

[Este510]

Ok the car dose not start once it's been started in the morning or after it's been off a couple of hours. I can smell the gas from inside the car, I assume it's flooding because if I disconnect the injectors it starts up for a second or two, but the second i reconnect them it floods. I tried turnig the fuel pressure regulator down but it dosen't help. I have spark, fuel, and compression, spark plugs are good and properly gapped, so what else should I check? Oh and once the car is on it runs strong no misfires, or bogging but it dose back fire a little when I let off.

I am runnig a sr20 redtop with a power fc, upgraded turbo, and 72# injectors.

Any info will be greatley appreciated!

Wheres all the nissan experts when you need them?

Try unplugging the coolant temp. sensor. The go bad and can cause that. The computer doesn't know how hot it is and floods the motor with fuel.

You may have a stuck/leaky injector.

The coolant temp sensor was replaced 3 months ago, I'll take a look at the injectors today. Can a stuck injector be fixed or do I have to buy a new one? Thanks for the info, anyone else with any tips?

This is what I would do, Even though you replaced it, it could have still gone bad.

I unplugged it and still the same thing happens. Now it dosen't start at all. It turns over and wants to start but nothing, it's just flooding.
