Right were to begin.
I bought a stolen recovered astra van which had a knackered head. It has the earlier 1.7td (gm engine). I had the engine fully reconditioned with a head from another van and put it all back together. The vans ignition has been wired in a way me or my dad (machanic of over 35 years) seen. Somehow they have by-passed the imobaliser so you can start the van with a non-transponder key.... Now the van takes ages to start any time of the day.....takes about 45 seconds of turning it over till it starts everytime not just at first. Have changed all the glow plugs just in case. The steering has interment failer as well Maybe once in a couple of days. This van is for my wifes florist and we do around 200 miles aday and stop start all day long. Please can someone shed some light on the nightmare of a van i have as its puzzled both me and my dad.
