Hi,
I've got a 95 Tahoe TBI, put the truck in park shut it down , now i've got a no start problem,it cranks but no start,the fuel pump does not come on,the injectors don't pulse,there is no spark,the service light does not come on , the fuel gauge is over full mark.
The things i'I have checked is , fuel pump relay (all good) ,Coil all good,put another dizzy in ,replaced the ECM , still no luck
Please if there is anyone with some idea it would help
