Have an intermittent starting issue with 2001 ranger. When engine is cold it starts and drives perfect but after driving about 20-30 minutes and engine is hot and you stop and shut off engine a minute or two and try to restart it will not start sometimes. Also you cannot hear the fuel pump prime for the one or two seconds when the key is turned to on position but if I let it sit and cool for 30 minutes or so it will start and run and drive perfect. I thought is might have been a bad fuel pump relay and replaced but it still does it but again it doesn't do it all the time. No engine codes either. Any ideas what would cause the fuel pump not to get power all of a sudden after the truck had been ruining then you shut it off and try to restart then nothing until it cools off??

 

Check the Inertia Switch. It could be your issue. That's what happened on my '06. But don't just look at it's face. I'd strongly recommend removing the housing and fully inspecting the switch, the wires and the connection. Mine looked great from the front. When I removed it, you could see the wiring harness was completely melted.

 

I did look at it and it was not switched off, can it still be faulty if not thrown?

It can definitely be faulty. Mine never triggered once, but I had the exact same problem you were having.

What I'm going to say next will probably upset some people on here, but oh well. I took mine out. Ran the wires to an inconspicuous spot and connected it instead to a toggle switch. Haven't had the issue once since I did that and now I have a fuel pump cutoff switch for extra security.

As an additional note, if you decided to do something like that, create a jumper wire. Toggle switches in this application can go out from time to time. I put quick connects on everything so that if the switch goes out, I can grab my jumper and connect the two wires together to be able to start the truck.

 

Thanks! I'll look at it.
