well i'm having a fuel system problem, so to start i changed the fuel pump because someone messed with the old one and put it on a switch. anyway still have the problem it starts fine when its cold but if you try to start it when its hot it just keeps cranking over. i'm going to replace the injectos next and i was wondering if i could put in 720cc secondaries and run it on stock ports? i'm going to port the engine later so i just dont want to buy injectors twice. i'm also going to run an rtek in the near future i just need the car to run so i can move it around lol my shop isnt very big haha.

 

i'm not an fc guy but i believe that switch was there to cut the fuel pump off to start the car easier, the fc is prone to flooding the engine on start-up, so u can shut the fuel pump off after the initial cranking to stop excess fuel from fouling the plugs. once the motor catches u gotta flick the switch to turn the pump on to sustain the idle and drive.

i could be totally wrong though. The fc guys will be chiming in shortly!!!

 

try changing out the Coolant sender at the Back of the Waterpump..That little "baby" there,tells the Ecu when the car is Hot,and regulates the Fuel,so to speak..if that sender is Screwed then the Engine will get fuel when cold(start up fine cold) but when hot.,gets Fuel like the engine is Cold,and therefore Hot start.. .and a fuel Cut switch is just a Lazy Man's way out of Fixing what is actually wrong.(Band-aid,as Aaron says).

 

If you just put in 720CC secondaries with no way to control them, you'll run seriously rich anytime they start firing. It will be like hitting a little wall.

 

okay i'll do that stuff and see where it gets me but the car will start and somewhat run with the 720cc untill i get the rtek to control them? cuz i dont need to drive the car but i need to be able to start it up to move it.
