So i know this is a no no but i posted this in the classis sentra section because it is a a 92 se-r but this area gets more traffic and is possibly a better place for this specific problem. If a mod would like to delete my other thread feel free... once again sorry for the cross forum post/spam

Ok so i have been in fights with my car on a day to day basis. I have replaced the distributor, spark plugs, wires, maf, re-grounded the maf again, fuel filter, fuel pressure regulator and ran heat through the tank (new tank as of 9 months ago [same fuel pump]). New Timing chain tensioner and gasket. Swapped out some JWT street 2 cams for the stockers before winter started. The engine is a JDM 10:1 sr20de in a 92 SE-R.

Problem: Intermittent problems, some days it will start fine some it will take a bit of cranking, some days it will NOT start

I have found that pulling the in car fuel pump fuse is sometimes a fix for the completely not starting but if this is the case the car chugs like it has bad fuel or has the maf unplugged. While driving the car runs like a beast as long as i have very light throttle or throttle PAST 1/2 other wise it feels like i have no power what so ever.

When it starts normal it runs fine and has no problems

Usually when it cranks for a bit then starts it has low idle issues but eventually runs normal.

The idle is not that steady, when the car is cold it will stall out if i do not keep on the throttle.

Car is a MAJOR pain to start in anything below 10 deg f.

I live in northern Minnesota so the temps have been anywhere from -20 to 30's.

I have read and read and searched over hundreds of posts and have seen the fuel pump fuse thing but no one had an answer that was posted so I'm hoping to get some assistance here. (http://www.sr20forum.com/200sx-se-r/...get-fixed.html)

My mechanic thinks it is possessed. aka maybe an ecu or fuel pressure issue (fuel pump) or something else really weird

Any help would be GREATLY appreciated,
Thanks to all in advance,

plz?

sound like your fuel pump might be dying! especially if you say it takes some cranking from time to time in order for it to turn on. when you try and give it full throttle seems like it doesn't get enough fuel but if you want to go through the diagnostic process to determine the cause i would suggest to buy a Haynes repair manual at a Autozone or parts store. I strongly suggest this manual for about $20. it will save you unnecessary replacement of parts.

get an inline fuel pressure gauge from autozone. There cheap. should be 37psi with the vacuum line attached 41psi W/O

My b14 did the same thing.. I cleaned the maf and it fixed the problem. Sounds like a weak fuel pump to me.
