04 Sentra 1.8S hard to start when warm.

[ledgewood6]

I have an 04 Sentra 1.8S which I bought used with 65 K. I have noticed that it starts great when the engine is cold....as well as when the engine is hot....but if I let it cool down for about a 1/2 hour up to an hour, it takes a while for it to start. It always eventually starts...but it make take 2-3 key turns and cranking to get it to start when it is warm. A prior day at a local Nissan dealer did not solve this problem. Any suggestions?

There is TSB for this in the knowledge base of this forum. It requires a repair kit for the fuel pump.

Thanks Streamcast... I checked out the TSB you mentioned and talked to Nissan Parts Dept and they tell me that the so called "repair kit" is essentially a new fuel pump...at $307 (plus installation). My car starts fine when the engine is cold or hot.....but only has longer cranking when the engine is warm. This sounds like a temperature sensor problem to me, and not a fuel pump problem. Do you have any thoughts? .

i had a similar problem with an '01 SE and it turned out to be the starter.

I have a similar problem with my '05 Sentra. Only when its been parked for a short period of time (maybe a few hours). If I pump the gas as I'm cranking and quit trying to start then crank again it fires up. Seems like a fuel problem.

I found a Service Bulletin NBT05-052a, "Long Engine Crank Before Starting" but download was messed up and will have to wait until tomorrow to download and read...

What happens is after the car starts when cold is normal, than is warmed up to operating temperatureor hot than let cool down to warm 1/2 hour or so the fuel pressure drops off and than it takes 2/3 cranks to start. It is a temp issue but for tthe fuel pump. The only fix is to performe the bulletin.
