check and see if you got power to the starter, maybe see if the fusable link is blown however i would think that nothing would work if that were the case

deer slayer · 09-01-2006, 10:21 PM

theres power to the starter

lilpup69chevy · 09-01-2006, 10:26 PM

does it have a solenoid you can jump across??? also like i said try the fusable link located close to the battery

neonlarry · 09-01-2006, 10:31 PM

When you turn the key to start do you have power to both large terminals on the starter or just one?

deer slayer · 09-01-2006, 10:50 PM

neonlary there is only one big terminal on the solenoid
lilpup yes it has a solenoid but it has two small post which do i use

lilpup69chevy · 09-01-2006, 11:27 PM

damn without knowing i would just say guess it i know you'll use one big post one little one try it both ways either way its not gonna shock you

its also possible your battery cable has came apart inside and your not getting power to the starter the rest of the truck gets power of the other wire of the terimal that run to the juntion box on the fender right above the battery

*screamin_eagle* · 09-02-2006, 04:00 AM

given you have it in park and its a good starter. I'd say you should check for resistance

If it is an auto be sure and check the neutral saftey switch

beautimus · 09-02-2006, 07:56 AM

If the truck is an automatic with column shift, i would say check the neutral safety switch, maybe hold up on the shift lever and try to start. but since its a 4x4 , i would asume its a stick shift, so that probably aint gonna help.
Have you had any indication of problems before now? maybe the starter not acting right before? if so i would suspect the solenoid, or the small wire going to it. i have had that wire burn in two inside the insulation, i couldnt tell untill i pulled on the wire and the isulation just pulled in two. thats where i would start. check that wire from end to end for continuity and if it shows good i would replace the solenoid. if that dont fix it then i would be stuck and have to ask somebody else. good luck, Tony
