1995 starting issue

1995 Tacoma, V6 Supercharged

I've been having intermittent starting issues that are getting worse. I replaced the battery but the issues continued. This morning I jumped it (started fine with a jump) and drove it for about an hour. It runs great. Multimeter on the battery terminals shows 14.55 DC when I first jumped it and hovered around 14.05 DC after running a bit. I assume alternator would be fine with these numbers.

About an hour later I went to start it again and I get no crank. I've read could be starter, could be vapor lock but I don't really know how to diagnose beyond what I have already done. Any help is appreciated.

 

So....when you get no crank......you can still start it with a jump?

 

Just throwing ideas out, but maybe a loose battery ground? Only thing I can think of that explains it won’t start with a good battery, but still starts when jumped. Or corroded terminals?

 

Start here...

Yes I've never had an issue starting with a jump. It cranks and starts right up. Without a jump I get no crank, no clicking, when trying to start a warm engine. Even if it's hot outside and the truck hasn't been running I have an issue. Cold starts seem fine

 

Thanks, I'll look at this.

 

Sounds like bad battery connections via corrosion or being loose

 

Load test the battery. It could be weak.
Loose batt connection.

 

Thanks I'll try this. Connections on the terminals are tight and clean.
