Question
Driving on the highway and suddenly stopped. Engine will turn easily but will not fire at all.  No weird smells. Any ideas. Thank you.

Answer
Hi Roy... could be a number of things...start by making sure you have spark, then fuel. check fuel pressure. if it turns over too easy, like no compression check the timing chain...when you turn the key on the fuel pump should run for 3 seconds...check fuses ECM and fuel pump and IGN.hope this helps
