Problem starting

[SINCITY_NSX]

I'm doing this post for a buddy I know every one on prime is smart so I hope you can help. Its an intermittent problem right now and I cant seam to figure it out. Last night I drove 10 min to the post office and when I got back out it to the car the engine wouldn’t start. It will crank over but it just wont start like it was out of gas but I have a full tank. I had it towed back to the house removed the fuel line to see it the pump was bad and it was pumping out gas when I turned the key so I put it all back to gather and went to check the spark and the car fired right up. Today I changed the fuel filter and I went on a 10 min drive and it did the same thing I had to crank the car over 5 times then it fired right up! Any ideas?

Is it the Main Relay?

Is the car stock? If not, and you've made fuel system additions/changes, it's most likely due to colder plugs and too much fuel at start up.

It's 100% stock! I was think it might be the relay.

If the main relay, fuel filter/pump have all checked out alright and you run out of ideas, try this. Might be oversimplifying things but I thought I'd mention it. I had experienced trouble starting after short distance drives as well (mine is stock, with cold weather and over 5500 ft) and I had read somewhere on prime to do something like the following.

Get in.
Put the key in.
Turn it so that you activate just the electrical (do not start the car).
Put on your seatbelt.
Then start the car.

When the electrical is activated, you've heard the fuel pump go on and the subtle sound of the fuel rumbling. During this time, I just fasten my seat belt and get situated, then the fuel rumbling usually has stopped. It's at this point, for me at least that the car starts without any hesitation and has worked everytime. However, there have been instances for short runs to the bank or store where I rushed it and did not wait and the car didn't start. I'll wait a few, start all over with this little technique and it starts up. If the car has been sitting for a long time, I don't have to do this and it starts right up. It's after short distances for me. I don't know if it could be an altitude thing, the cold winter or what. Anyways, I hope you figure it out.
