Hello everyone I have a 2005 nissan sentra 1.8L with a starting problem. Almost every time I start the car it takes at least 2 or 3 tries to start, it has never left me stranded but it is also VERY annoying. It has been an ongoing problem for as long as I have had the car (almost a year.) In the mornings, or when its left alone for awhile (maybe 3-4 hours) it USUALLY starts perfect first try. It is when it is left alone for about 10 minutes to an hour is when this problem starts to arise. I have changed all the spark plugs and my fuel pump. The car is almost at 180k (oil regularly changed by me) and NO CHECK ENGINE LIGHT. If you have any input or insight on this problem it will be greatly appreciated!!

Try cycling the ignition switch on and off 3-4 times without starting the car
to prime the system then try to start the car. If it starts fuel pump/pressure
is the problem. Did you use a Nissan fp for the replacement?http://www.ericthecarguy.com/faq/solving-automotive-no-start-problems
When you changed fuel pump, did you just do pump or the whole assembly. There have been problems with the fuel pressure regulators on them. I beleave the pressure regulator is part of the assembly. Do what College Man said, if starts then regulator. If you can test fuel pressure you can see if the pressure bleeds off soon after shutting it off. good luck.

I’m pretty sure I changed the whole assembly, because like you said the fuel pressure regulator is apart of the assembly (so is the fuel filter and what not.) But, I have tried priming the fuel pump before and still no luck on starting first try.
Just a thought if it were the fuel pressure as suggested wouldnt it fault after sitting for long periods also not just random 10min or 1hr.
Still worth while checking your pressure just to know its ok.
Does it run ok when it starts or does it cough and fart for a bit and eventuallt clear itself?
One more thing. When it doesnt want to start hold your foot flat on accelerator and wind it over and see if it wants to start. Ive had vehicle in the past (older p11 nissan primeras) that flood themselves after short trips. Different vehicle i know but may help narrow down your issue.

It does run ok when it starts. I used to have a few misfires when it would start but I changed two of my coil packs and it hasn’t happened since. I do give it some gas sometimes when it is taking long to start and it usually will get it going but I have never completely held my foot flat on the accelerator. *update* I also did clean it with seafoam this weekend just to clean it and I still have the issue.
