Legnum doesn’t like right turns

[marc mtp]

Ok guys my legnum is playing up , around most right hand bends it’s missing or ignition cutting for a second but on longer sweeping bends it goes for longer , I’ve played with connections and can’t see any issues ,thinking ignition or fuel ( and no I can’t always go left turns lol) any ideas

 

[Gav]

Could be fuel pump. That’s why it’s only on right bends. Or could be ignition leads. And they are moving when you go around a bend.

I’m sure others that are more experienced with these cars will offer some advice or ideas

 

[marc mtp]

While the car was stationary, running I move connectors and can’t get a stumble. Will hook up see if any codes

Take your fuel pump out and have a look at the pickup etc.

don't turn right do a lefty

is it auto or manual

 

[6A13TT TYPE S]

Sounds like fuel pump to me

 

[Legnooms]

try unplug MAF too, should run fine without it but if the connection or unit has any faults it won't like the sensor dropping in and out.
Make sure plenty of fuel. Check grounding straps, battery terminals, wiggle spark leads while idling. All that stuff is easy takes 5 mins to test. Might be lucky

Sorry wish I can help but I have a question.
Just curious why it would it might be the actual fuel pump that a few said if turning right ?

 

[Legnooms]

When you turn right the fuel will bank to the left side of your tank which could be starving the pump.
My partner's territory if below 160km to empty cannot start on a downward slope lol

 

[Nitephyre]

Shouldn't it be starving when you turn LEFT, as the fuel pump is on the RIGHT.

 

[Cameron McPherson]

Nah.

Turn left, fuel sloshes to outside of the car (RHS/Driver's side) for pump to pickup.

Turn right, fuel goes to the left side of the car away from the pump.

Fuel always wants to oversteer so goes in the opposite direction of the corner.

So if he had a full tank, then he shouldn't have this problem ?

Also "marc mtp" does it still have this problem with a full tank ?

 

[marc mtp]

Filled to 3/4 no problems 2days later back on half tank and just did it around last corner before home , I have checked codes , checked connections while idling not a stumble , I still thinking electrical

 

[marc mtp]

While idling unplugged maf , went a bit lower in revs and lumpy as , wiggled all connections I could put my hands on not a stumble, also it auto

 

[marc mtp]

I get code 25 barometric pressure sensor with evoscan , can’t imagine this would cause it stumble for a split second whilst turning right

 

[naughtika]

borrow MAF from someone?

 

[marc mtp]

Got a new pump will put it in see how it goes

 

[naughtika]

goodluck!!

I recall someone from CVR4 had similar issue. Just can't recall if how it was fixed or what actually caused the issue

 

[Cocko]

Adam had similar issue with his silver beast. Fuel pump and filter was the culprit there.

 

[marc mtp]

Installed the walbro from Steve with no resolve to the issue still doing it
