ok next problem!

ok have sorted the van now it runs and fires up but when i relese the key the engine dies as well what can be causing this

 

my guess would be that you have your ignition live fed wires for the engine wired up to your cranking postion (ignition3) rather than igition 2 setting.

 

thanks for the help will give that a shot

 

updated tried the above

ok its deffinatly not the ignition switch as I cut the starter cable of the ignition switch so it would disengage when I take it off the live all the other cables work accesory and igntion circuit.

so ignition on alarm disarmed tocuhed the starter cable on the live van fired up opened accelerator keeping the starter cable on the live kept it on for 30 second and then took the cable the engine cut out still wouldnt stay running

tried this at both ends of the car kept the starte cable on the lie at the ignition and connected to the plug in the engine bay does the same thing

any ideas ?
