Hello folks...hope all is well
I removed my Eforce supercharger and went back to a OEM manifold and injectors...I also sent my ECM out to have it retuned by East Coast superchargers...today I plan on reinstalling the retuned ECM ...my question is this...since the oem fuel rail (is empty or not full or gas) is used along with the stock injectors...is there anything I need to do...in regards to getting fuel pressurized on the initial startup...or will the fuel system pressurize itself...and are there any other suggestions...valve covers are tight....belt is good...coils are hooked up...my friend says...just turn the key without firing the engine...BUD!!...I DO NOT HAVE A KEY!!

 

No disrespect, but why don't you just ask Doug or Chris at ECS what they recommend?

 

I've done this too many times lately, no you don't need to do anything. Even though the system is closed loop it fills quickly, mine starts almost immediately & runs smoothly.

 

If you floor the gas pedal, engine will crank for about 5 seconds, but will not start. Do this twice, and should start up fine on the third start, but not touching the gas pedal the third time.

As for priming the rail if dry from the tank forward, schrader valve on the drivers side front rail, and you can just the fuel pump relay out to run the pump without the motor begin started. Hence pull the rail cover upwards in the front, pull the plastic cap, remove the valve with the tool, shove a hose on the valve with the other end in a gas can, pull the starter fuse and jump it, wait for the fuel to flow into the gas can, then put it all back together again. Now do the one start with pedal floored so the starter cranks for about 5 seconds to charge the other side of the rail without the motor starting, then take you foot off the gas pedal and hit the starter button to start the motor.




Note, looking at the rail from the bottom side, so valve will still be on the front side of the motor drivers side,





To add, the starter jump, valve pull with hose on it to gas can, its the quick way to empty passenger fuel tank, since you will never get to it with a siphoning hose. Once the fuel gas gauge is under 1/2 full, the passenger tank is empty, since it the first one that empties to start with.

 

thanks to everyone...vette runs perfect!!!!
