Customer Question

2008 Nissan rogue starts then stalls
Submitted: 1 year ago.
Category: Nissan
Expert:  Jake replied 1 year ago.
Hey there, is it hard to start start all?
Is the service engine light on? Or security lamp when starting?
Customer: replied 1 year ago.
check engine lite on for running lean po171,has new fuel pump and air flow meter,starts aesy,no security light,it started doing this a day after an oil change
Expert:  Jake replied 1 year ago.
If it started the day after an oil change the first thing I would check is that the air box is shut. Have seen many lube shops check the air filters then not close them properly and cause surging and stumbling.
Secondly a lean code condition that is not caused by the MAF, is going to be either an air leak of a faulty A/F sensor itself. The easiest way to check would be to look at some live data. Does your scan tool have that capability?

tapped on IPDM ,car started and idles,idles up and down a little,if I change ipdm are there any precautions
Customer: replied 1 year ago.
po171 code came back
Expert:  Jake replied 1 year ago.
The IPDM is plug and play. There is no programming required at all.
I don't know what you previous readings were sonic you could post those that would be helpful. Live data can tell slot about fuel trims and lean or rich conditions.

Customer: replied 1 year ago.
wouldn't start or stay running yesterday,changed ipdm,still wont stay running,,will run on carb cleaner if you spray into intake
Expert:  Jake replied 1 year ago.
What voltage reading are you getting to the pump?
Customer: replied 1 year ago.
will check in morning,what should I be getting
Expert:  Jake replied 1 year ago.
12v
Customer: replied 1 year ago.
smoke tested intake ,only leak I could find was around seem in box air filter is housed in,not a big leak
Expert:  Jake replied 1 year ago.
I'm not worried about intake if it runs on starting fluid. Get me that pump voltage
Customer: replied 1 year ago.
ok
Customer: replied 1 year ago.
voltage stays at 12 volts ,it still dies
Expert:  Jake replied 1 year ago.
YEA, that's not making a lot of sense. So let me clarify. The car WILL RUN ON CARB CLEANER, but not otherwise. Voltage to the pump is the proper 12v from the IPDM have you checked fuel pressure yet?
