Car Wont Start

[poonman]

95 n/a man For a little time now i have been having problems with my autoshut down relay tripping and all i do is change it and it fires back up again well this mourning i drove to work and died as usaual, i changed the relay and it fired right up for half a second and died again now everytime i change the relays nothing happends nothing i can do is starting the car, i dont even hear the fuel pump relay coming on, but i know they all work because i have jumped them and they click like they should i have even jumped both relays with wires and still nothing, it just wont start at all no matter what electrical thing i do to it.

it isnt equiped with anti theft is it??

Just the one i had installed, Autopage but it cranks over fine and i can bypass the relays so the fuel will flow and signal sent to the Coils

make sure you have power at the fuel pump. If you have acces to a fuel pressure gauge attach it and look at it when your car dies to see if it cutting fuel. This should help you narrow things down.

I dont both me relays arent getting turned on from the ECU if i jump the relays it gets plenty of gas.

if it wasnt doing after you installed the anti theft system then check and make sure all the wiring from reley to the ecm are good. If your computer has all the inputs it needs and the signal isnt coming out suspect bad ecm.

ok im still back to square one and my ALARM has NOTHING to do with it. The Auto shut down RELAY is getting all the positives but the ECU is NOT sending the negative signal to turn ON the Fuel Pump relay AND the Auto Shut Down relay. If (I) bypass the Negative signal and give it my own NOT from the ECU and it still doesnt Start, What could it be. Is it possible that it could be a Crank or Cam Sensor, Also my ECU has a whistle in it but the caps dont look like they are leaking. But as I mentioned before. It does this from time to time and all I do is mess with the ASD relay and change it and it fires up, This time i changed it had no effect.
