GSR possible fuel pump issue

[Dylan Coombes]

Ok so maybe 3-5 seconds after starting the car yesterday it spluttered and died, did this the next 5 times after this as well. I tried revving it after starting and it just died at 2000rpm. IF it is the fuel pump I've decided I may as well upgrade it while I'm at it so what would be the best option? I don't need anything crazy just enough to support any future mild mods. Walbro? Bosch?

 

[mathew_colville]

im not sure if its the best option but i run a walbro 255l pump (gss342)on my 4g93t, not a huge pump but will be able to handle some upgrades
its louder than a stock pump but walbros always have been. i dont know if the bosch is quieter?
just make sure you get a genuine one, not a knock off
it went in quiet easy and i was able to put the sock on it to make it a little quieter

 

[Dylan Coombes]

Yeah that's what I had in mind, mainly because I don't know any other ones haha. Priced up a Mitsi replacement at $250 or some shiit. Think after market is cheaper? Unless trademe ones are knock offs

 

[evo-gsr]

Walbro are the most common replacement and have been known to be capable up to around 280kw

I have the duetsworks 300. Quiet like a church mouse. Actually its a bit noisy but not too bad.

Another option (which I'm using) is the Aeromotive 340, straight fit, dead quiet and e85 compatible.

Is it necessary to replace the fuel filter while replacing the pump as well?...or at all for that matter?

I dont think its necessary, but if it hasnt been changed in a long time it probably wouldnt hurt

 

[VIN18M]

Good idea to

 

[Dylan Coombes]

replaced the fuel pump to an evo 2 unit and it hasnt made any difference. still idling rough for a few seconds before cutting out. also sounds a lill rough when cranking it over, almost like its running on 3 cylinders

Are you sure the spark plug leads are connected in the right firing order?

 

[Dylan Coombes]

Yup. Had a blown coil pack. Replaced it with a new one and worked fine for the drive home but then crapped out again the next day. So what could be causing the coil pack to shit itself?

Bad connection to the crank angle sensor?? check to see if theres any broken wiring on the plug or any corrosion

 

[BYBY5L]

Check grounding too, could be worth swapping out the tr power unit also,

 

[Dylan Coombes]

coils and tr power unit all tested fine by the sparky. had a quick look at the plug on the cas and nothing looks out of place. will have to have a proper look sometime. couldnt be bad leads or plugs? unsure how old they are

 

[Dylan Coombes]

Ohh CRANK ANGLE SENSOR lol where the f is that?

 

[BYBY5L]

Plugs being so cheap are definately worth a try, and could def be leads arcing out too,
I got spare leads if ya in melb nth (on the phone an cant see ya location), def welcome to borrow them, save ya wasting money if its not

 

[Dylan Coombes]

Cheers but na just a bit further away... Hamilton nz haha

 

[BYBY5L]

Oh true, i grew up over the mount! Lol
Hope ya get it sorted
