I just installed a Heath boostmaster and new towing ecu on my 98 6.5 I also put on a new stanadyne pmd,The truck ran great for about 20 miles then stalled out,It actually burnt a hole thru the back of the pmd and melted some of the connector,Now I have replaced the pmd with a heath unit and it will not fire,I also noticed my wait to start lite does not come on,I have checked all fuses and grounds and it looks good,

Any ideas would be appreciated before I start throwing money at it.Thanks

 

shorted out the ecu?
