I have been having some strange starting problems in the winter season so far. I have a 1995 se at 141K and the this is the first winter in three years I have experienced this. The symptoms of the starting is longer crank and sounds like its about to kick over. sometimes I will tap the gas pedal once or twice and that will help it kick over. Once the car is warmed up it is a little better, but it stills will act up once and awhile when warm too. I have been trying different things to try help with the starting problems. I put a new battery in during the fall. I just seafoamed about a week ago and I also try cleaning the iavc too. I made and installed a grounding kit and I try using HEET to maybe help with moisture in the gas. I regularing use injector cleaner too.

I know there the car is old and wont start like a new car, but it has always had a very clean start over the three years. It can be summer or below 0 and no problems. Im just trying to figure out what could.


I have been trying to catch a video of when its real bad
Heres a video of when its a slight hesitation...
I have been searching for awhile and any imput will be appreciated.

 

Looks and sounds fine to me.

 

engine coolant temp sensor if it wants to shut off and only does so in the winter

 

starters dragging...

 

the video isnt the best showing of the symptom. Im trying to get a video of when i have to hit the gas to get it going. Everytime I pull the camera out it wants to start good lol.

 

Kinda hard to tell. During cold weather, you lose cranking amps, so that could be a possibility.

OP, about how cold does it get before you start to encounter this situation?

 

I'm in Chicago so it's in the 20's. the problem seems to happen more after I have driven the car for awhile, then let it sit for a few hours and it gets cold again.

 

sounds like the engine coolant temp sensor. i have that same issue only when its cold. it'll start then die out unless i give it some gas.

 

what grade engine oil do you run in winter?

 

Engines start harder in cold weather. Yours sounds real good. Placebo works both ways and I think you are imagining it worse than it really is.

 

Had a similar problem with cold starts when it was cold. Turned out to be the fuel filter. Problem started when it got cold

well yesterday I have noticed the symptom usually happens after the car has been driven and warmed up, then sits for a for couple hours and gets cold again. If it sits overnight it starts up fine in the mornings.

 

hmm I just changed mine in the summer. only about 6 thousand miles on it.

 

no $hit??? after sitting outside in -32 farenheit it gets cold again?? how could this happen??? did'nt nissan put a heater on the engine to keep it warm in the winter???

 

well i meant to say the difference between sitting for a few hours and sitting all night. I see it act up more when it only sits for a few hours then try to start it again.

 

Ive been looking around online and people with failing FPR seem to have symptoms like this. might check that out tomorrow.

 

Before checking into the FPR...

Have u done a tune up? Clean the Throttle body and MAF. Replace Engine coolant temp sensor and PCV valve and fuel filter.

COuld be the FPR as well, but all of the above can also cause hard starts.

 

I cleaned my IAVC about 2 weeks ago and checked the throttle body and looked really clean. replaced the MAF and fuel filter over the summer. The coolant temp sensor was replaced about a year ago and I just put a new pvc last week.

 

i know, i'm just yankin your chain man...
