Check your throttle positioning sensor, it may be sticking when the engine cools down, and may be flooding your vehicle. It should come up on a diagnostic tester, in the codes.

2000 Yukon denali having trouble starting. Sounds flooded. After it sits awhile it will start. Replaced fuel pump. Still having problem. Security light is on. Replaced ignition switch. Please advise.

If it is flooding,fuel is not the problem.Sorry you did a pump already.You need to check spark and air,I would start with spark.Check your plugs for spark.If they all spark normal,that also means the ignition coil is good.That leaves air.Check the filter and intake hose for leaks,holes,etc.I would guess spark,but you never know what you'll find.If you are not 100% sure how to check spark,sounds like you probably do though,just comment on this post and I get an auto email linked to here and tell you the best method.Good luck!

2000 Yukon Hard to start, rough accelleration

First things first. The morter is direct injection, no throttle body. The injectors inject fuel directly into the cylinder. A few possible simple causes. Bad gas is and can always be a contender (my mom had the exact same issue with it stalling). Try putting some water remover in the tank and going to a station that has lots of traffic (gas doesn't sit as long and is less likely to have water in it). Also you can use Lucus fuel treatment in each fill up to help prevent fuel breaking down. The injectors could possibly be going bad (hard start, hesitation are also signs of injectors) but could also be a failing fuel pump or fuel filter may be geting plugged. Also the CPS crank position snesor which would also contribute to this issue. I would start by taking it to the local parts store for code scanning to see if it points you anywhere specific first and if not then start with the cheapest things first or have a no start diagnostics performed at a service shop..

Starting problem after engines warm smell gas

I had the same problem. It may start to or already is stalling as you slow down or stop. I changed my fuel pressure switch located right on the fuel rail on top of the motor. It's about $80.

Nissan Sentra Series 3 won't start

I have the same problem. When I let the car sit over night it cranks right up, but if I cut it off it is off for hours and won't crank.
