At start-up it smells like it is flooded but it starts up fine and no codes. Sometimes lately right after it starts it dies after a few seconds. Any ideas what causes this would be appreciated.

 

Define "no codes" please.

When did the problem start?

How long has it been since you replaced the plugs/wires/cap/rotor and filters?

Have you pulled the plugs to look for signs of unburned fuel/rich condition?

 

Define "no codes" please. Ran key off scan and received no codes

When did the problem start? The smell which detected by better-half has been that way awhile

How long has it been since you replaced the plugs/wires/cap/rotor and filters? About 35,000 ago

Have you pulled the plugs to look for signs of unburned fuel/rich condition? No but will do tomorrow.
Thanks for the reply

 

And, is gas smell limited to just start up? I had a constant gas smell that came from a leaky tank where lower support rubbed the tank.

 

No it seems to be just when I start. Seems to me the smell is coming form the exhaust.

 

At the very least you should get the System Pass code of 111, then repeated for the Key On Engine Off tests. You will also get the same thing if there are no stored codes in Continuous Memory. Anything less means you were not successful when you tried to run the KOEO test/CM display.

 

I forgot to say I got 111 then 10. I will do engine on after work and see what I get

 

The "10" is the separator code between the KOEO test and CM display. At least we know for sure now there are no apparent codes causing your issue. The KOER tests may reveal more.

I also highly suggest you check the Fuel Pressure Regulator for signs of a ruptured diaphragm. This will allow fuel to be drawn into the intake. Remove the vacuum line from the FPR, then cycle the key a few times. If you smell or see fuel coming out of the FPR, replace it. This is a very common problem.

Plugs that look gas fouled is another symptom of a leaking Fuel Pressure Regulator.
