Just bought this was running 2 days later will only crank over when warm, Any help appreciate. Replaced Fuel pump, spark plugs and fuel pump relay.
if it wont even crank over on starter its nothing to do with the engine management, the starter motor is fed by the ignition switch pretty much direct. if its got an aftermarket or dealer fit alarm/immobiliser then this could be suspect, or if its an automatic maybe a problem with the interlock system. look at the ignition switch wiring to the fusebox as best you can, the cranking live is the thick red/black. check the wiring to the starter motor as well
