you will have to be more specific,is the engine turning over?battery in good condition?If it seems to turn over ok then would check heater plugs are ok,filters are clean and renewed if in doubt,and a code reader may help also.I know there was a fault on these where an engine ecu bolted to rear of the block gave a lot of problems and you could open these up and have a smell for burning and also look for soldered joints on the pcb burnt out,just some things to check.
