Car starts cold without issues

 

If run to store and restart, takes a few times to start. Cranks but doesn't turn over. Does eventually start.

 

Recently had main relay recall completed wth-68

Also they completed following update

11-162-16

11-162-16R

 

Since taking in for the previous stated recall and update, I've had the same issues. Rafferty Subaru didn't have issues starting while in their shop.

Anybody have similar issues?

ask them if they can put some kind of monitoring device on it that will record what's happening during the no start condition.

and of course if you can recreate it for them - that would be ideal.  keep taking notes on a pattern in case it's something repeatable.

 

any check engine or other lights?

 

if it does it again - turn the key to ON without starting the car 2 or 4 times.  then try to start.  does that help it start?  

if so that would indicate a fueling issue.

No check engine light

 

Once started, runs great, gas mileage is phenomenal at over 40mpg.

 

I can hear fuel pump activate when turning key and will try to see if priming will eliminate issues.

 

Thank you for your quick response

I would guess it's the fuel pressure regulator which is internal to the fuel pump.

 

This guy hasn't figured it out yet but may be headed int he same direction:

If that's the case - then monitoring the fuel pressure when the issue presents itself is the key. But that's not routinely done on Subarus or easy to do.

 

If you could post back once you find out the root cause that would be great.

is the store very close? such that the car has not warmed up?

It's a 15-20 minute drive

 

Originally it was repeated, but they claimed to fix with main relay recall replacement

 

Today was in the 50's here, didn't have any issues all day. Not sure if that's a coincidence or the weather is playing a factor.

Previous few days were much colder and yesterday was very rainy

 

With the car having such low mileage, they were hesitant to check fuel system. They seemed determined it was electrical, hence the ecu flash.

 

I will keep updated, thanks for input

Today drove to Ikea, 30 minutes, car sat for 35 minutes while inside. Tried to start and only cranked. Turned key off and restarted immediately.

Weather today is close to 50 and dry which contradicts my wet weather theory.

Has been at dealership for 2 days

 

1st diagnosis

Replaced crankshaft sensor

 

Still continued extended crank when hot

 

2nd Diagnosis - low fuel pressure

Replaced entire fuel pump

 

Picking up tonight

 

Thanks grossgary for your insight
