<p>[QUOTE=&quot;Studebaker Hawk, post: 4041281, member: 51267&quot;]Maybe newer trucks have an electric pump feeding the injectors,mine is still the old fashioned mechanical pump, but the law of the land (NHTSA rules) all vehicles that have an electric fuel pump that is&nbsp; in any collision the circuit must disconnect. The circuit is sensitive enough that a strong bump may disconnect the circuit disabling the vehicle unintentionally. That is why&nbsp; cars produced this way have an easily reached reset in the trunk or rear of the car.</p><p>But as been said, there is plenty of diesel fuel vapors around, ruptured tanks, battery boxes nearby which probably go to a grounded circuit at the chassis with a thick (3-0) battery cable providing a significant spark and heat. Lots of plastics on newer trucks light up pretty easily, and aluminum when it gets hot enough eventually catches fire.[/QUOTE]</p><p><br /></p>
