We are putting back together and 05 G35 rev that has been sitting for a little over a year. Had it all back together and for some reason we couldnt get fuel to the rails after priming it about 10 times.

Replaced the stock pump that was out of the car for about 2 yrs with a 255 Walbro. That got us fuel to the damper. We then tried checking the injectors which have also been sitting out of the car for a good 2 yrs. They were wet on fuel rail side but dry on the manifold side.

So now im stuck at a dead spot. Is there anyway to check the stock fuel pressure on the damper?

Any help would be appreciated.


*******Fixed....Just in case anyone else has problems. Turned out to be the regulator which is found in the bottom of the fuel sending unit in the tank. Fixed that built up 50 psi and it hit on first crank. Car runs great now.

 

You on a stock regulator?

 

Yes. The damper is stock. It looks like its flowing fuel just not building enough pressure to push fuel through the injectors. Even borrowed a set of stock injectors from another local who just had his car running.

Today im pulling his damper to see if thats the problem. Used to a v8 this returnless system is killing me.

 

yea id check the simple things first, stock lines, stock regulator, etc. is the car modded, or 100% stock??

 

Yeah still no luck picked up another persons dampers that were on a working car and put them in then blew the fuel line with compressed air to clean. Took apart the fuel unit and blew air through all that. Last thing to try is yanking the assembly out of the other guys and swapping it.

The original owner told me today he had to remove the stock regulator in order to fit an aftermarket kit in. Hopefully its a seized regulator swapping out now to see.
