I have a 2000 with a 4.3 v6. It has trouble starting but once it is hooked up to another car with jumper cables it startes no problem. i assumed it was the battery or connection so i just replaced the battery and still no luck. i need help.

 

i had this same problem but with mine..it wouldn't start for crap unless it was cold started, my mechanic said it was a bad terminalor a bad terminal connector.(haven't replaced either no money to get it done yet)...its still doing it to this day..but..i hardly drive it so its not a creitical situation..YET...thats some thing else to get done w/it..*rolld eyes* it NEVER ends...sorry i doubt this was any help at all lol

 

Have you had the starter, alternator, and ignition coil tested?

 

Is your alternator putting out enough voltage when you have the vehicle running?

 

the alternator is putting out plenty of juice. my problem is it has trouble starting all the time hot or cold. all the time.

 

If the alternator wasn't putting out enough to charge the battery, then that could have been it. But seeing as you are getting enough juice, it could be other things like the starter may be possibly bad/going bad.

 

I repeat.

 

it seems to that it wouldnt start period if the starter or coil was defective. and it sounds like the starter is working find, turns over no problem.

 

Check the cables for corrosion on BOTH ends of both cables. You might have to twist them to see if any crap is inside. If it only starts hot or cold by jumping you probably got bad cables. You could also check them for resistance but I don't know what they should read, should be pretty low I would guess.

 

Think not, huh? Fine. 'Sounds like', 'looks like', 'feels like' don't tell you anything. Anything electrical or mechanical can be working, but not at full capacity, and not do what it's supposed to do. Hope you solve the problem, though.
