Hi All-

First, I have a '00 SD 5.4, automatic, no alarm or remote start.

I'm getting an intermitten starting problem when the truck is warmed up. I'll drive it for maybe 20 minutes, shut it down, come back to start it in 10-15 minutes, and nothing, no clicks or anything. The dash lights come on, the battery is good. I've tried shifting into N, jumping it, tapping on the starter...

An hour or so later, it starts right up.

Any ideas?

Thanks-
Jeff

 

Sounds funny but check your battery cables for corrosion. If they're clean, I'd keep looking. Solenoid? Starter? You say the battery is good....did you have it checked (althought it doesn't sound like a battery)?

 

Welcome to FTE!

My first guess would be your starter or starter solenoid is failing when it gets hot. As it cools down it works again.

 

This stuff is right on.

If bat is good and you jump across the solenoid and it starts the solenoid needs changing. If not it is probably the starter. There could be a bad safety switch,, but I would put the $$ on the starter if the solenoid passes the jump test.

 

Thanks for the replys...

Looks like it was the solenoid, I switched it out last night, so far so good!

It could also be in the key ignition, my '99' will do that all I have to do is wiggle the key alittle.

 

Good, glad it worked out.
