I have had intermittent crank no start issues with my 2004 Ranger 3.0 V6 XLT SuperCab with 100K miles. I am close to figuring out the whole problem. The other day the crank no start happened again and using my knowledge that I have been able to google I found the suspect major contributor. I am uploading photos showing what I found. During my trouble shooting this time, after getting the truck started, I happened to reach up under the dash to check the FPIS after the truck had been running for about 2 minutes and noticed the wires going to the switch were very hot. I'd guess at least 130 degrees F. I shut the truck off and dismounted the switch from the firewall, and the pics show what I found. This is a very serious fire hazard that any Ranger/Bronco II owner should be aware of. I have a good relationship with one of the local Ford service departments and plan to be working with them to go any further to resolve my issue. The intent of this posting is to get the word out about this condition and that any and all Ford vehicle owners of the mid 1990's to about 2011 should inspect this FPIS wiring and connector. For my 2004 Ranger this component is on the inside firewall just in front of the passenger's foot area under the dashboard. Likely in a different location on any ford of this era. I will add updates to this forum with my progress in resolving this issue.
