Ok, understand. No electrical power.

Huh? You hit the clutch? Are trying to describe a rolling start? And it failed to start with a rolling start right? If you have no electrical power, the injectors won't fire, the coil won't fire, the car won't run.

no no no , when i stomp on the clutch while standing still, car is not moving , and i have full electrical power aswell

What?

If the engine doesn't crank over, but you have electrical power, why don't you say so. Right now, I don't really know what you have.

engine wont crank

when u turn the key i have full power , its a brand new battery, and I hear injectors squriting so fluids are comming in to the engine.

so therefore im figuring its a soleinoid or switch or relay of some sort,

thanks for the inquiry

Quick way to test if it's the Clutch start switch (no neutral switch).

Get a short piece of wire stripped at both ends (1" or so would do just fine)
Look for a plug going into a switch behind the clutch pedal (just high enough to be out of sight from the driver seat)
Unplug the switch, and use the piece of wire to 'jump' the plug

If it starts, it's the switch. You can be cheap and tape the wire in place (remembering to always have it in neutral or have the clutch in when starting), or go buy a new switch.

If it doesn't start, check the relay on the Pass side next.

Edit: Wait? What? Now I am confused.

A couple of quick things. The injectors don't pulse with out a crank signal. So you don't really hear them.

There is two wires on the starter. A big one, that should be 12V. The little one should be 12V (B+) with the key in start position only. Have your buddy put it in the start postion when you are down there with a meter. If it shows battery power, you have a starter problem. If it shows nothing, pull the schematic and start checking the circuit.

thanks for the help i figured it out sorry for the hole forum it was stupid for me to start it the problem was the starter power supply and i got a brand new connection and it works fine

Aha, a bad starter power supply. Come on Nick...didn't they teach you anything?
