had a vn out the back for a while and started it every now and then.decided im going to put it back on the road for my daughter as it shouldnt need much.I started it up the other day and it seemed to be running ok and and i put it in park and let it idle for a minute then gave it a couple of light revs and it gave like a slight backfire and stopped and i cant get it started again.i have tried another fuel pump and replaced fuel filter,changed to another throttle body with sensors,changed all relays and even tried another ecm and tried the coil pack with a spare spark plug into the leads and onto the body.have have read on here to pull the rubber hose that goes to the fuel rail off and fuel should pump out as i turn car over is this correct?have tried this and have no fuel spraying out.any help greatly appreciated.thanks
