Slow start with new battery

Slow start with new battery

Postby joshkeast [OP] » Mar 09 2011, 12:22am

I just rebuilt my engine after a valve job, had issues getting it running (see previous posts) finally got everything running good but it was kind of slow to start afterward. I assumed it was because of a 4 year old battery and the constant strain of trying to start the truck during the repair and recharging. It was time to buy a new battery anyway. So I just installed a brand new NAPA 840 cca battery and have been driving around, charging it with the alternator, but my truck is still dragging a little before it starts. The cam retard offset is at -1 which is within specs. I'm just wondering what would cause this lull before ignition? Could it just be the temp outside? Today it was around 40* F.

Thanks in advance.

My truck starts a little hard in the extreme cold, but up here in Minnesota, cold means -15F. Is the starter OK?

I'm not positive. It did get quite a work out before i figured out the valves. I imagine its gonna need replaced here pretty soon. I'm just trying to make sure this truck is mechanically sound, I bought it about 8 months ago and have found out the previous owners flat out lied to me about the work they did to it.

Might be obvious but check for corrosion at the batt. cables and on the connections on the starter.

It's got a brand new battery I just installed today. I haven't checked the starter yet because it was snowing and raining today.

Good chance the starter is worn out. Not to bad to pull and have it bench tested.

Keep us posted on your work- now's your chance to treat the truck right, since the previous owners didn't.

Double check the connections, especially the chassis ground

You might also get a meter and check the resistance in both the + and - cables. Being a '96, you could have corrosion that's found its way inside the cables and that causes big problems. Also make sure you follow Hartski's suggestion to check and clean up the chassis ground. That's something that probably never gets checked on the average vehicle. After all of this is done, I'd have the starter bench tested. Good luck!
