Cranks but will not start

Yeah. Thanks yeah, I know the general procedures for determining spark and fuel. I think it's getting fuel I could hear a humming it's going to tell me no spark that I already fairly sure on. What I wasn't sure was that oil being so high, plus I've never dealt with a car that just sat that long without even being turned. Well, I'm going to check the compression especially in that first cylinder that had the misfire code on it check the fuel and spark, change the oil, and then we'll take it from there and I'll probably need help, so I'll get back with you again and thank you. Oh, one more thing. What's the best way to purge that gas tank so I can put fresh clean fuel in it, or do you think that's not necessary?

Hey thanks, I'll be getting back with that car either today or tomorrow and if the common issues of fails to start it I'll get back with you. I will let you know regardles. Thank you

Tuesday morning I've just gotten back to the Sentra I got so far as draining the oil and it smells like gasoline. I know this isn't good but how bad is it?

Thank you so much and for continuing. Do you think that a bad at fuel pressure regulator on this car could cause that problem? And if so, how would I test that the fuel pump is good?

You still with me SQM? I took a break from that Nissan. I'll be back at it Tuesday I did get the oil changed to where it should be. The spark plugs were completely fouled. I put four new ones in and that's when I left. On Tuesday I'm going to check and see if it's getting spark and fuel and if it's not gone from there. I have a question: Everything I've read says check the compression with the engine warmed up. If you got no start, can you check it without starting it first or would I be wasting my time?

I'll let you know what happens with it Tuesday night or Wednesday.

All right I'm back. Hope your still with me on this SQM. Out of town unexpected for over a week I just got back to the Nissan yesterday I already put new plugs in it last week, so I decided to crank it and third or fourth try it started. It ran real ratty stalled after about 10 seconds same thing a couple more times started stalled, and then it ran for a while. Started every time after that and ran until I shut it off, but it runs really ratty. I mean any gas at all it'll stall. SQM, in your opinion what should my next diagnostic step be? I know there's a lot of things that could be doing this, but keep in mind when I first got it, I ran the ECU codes and got back p301 codes and fuel temperature sensor circuit codes and that would have been from 6 - 7 months ago when it was started last and is a persistent enough of a problem that it filled the crankcase half full of gasoline. I didn't have my code reader with me yesterday when I stopped by and saw it, but I will definitely take it with me today and erase the old codes or run a new code and of course, I will check the cylinder one coil and fuel injector and then, if they're both good and check out please bless me with what my next diagnostic step should be, so Great and Knowledgeable One.
