Hello,

I am new to this. 1986 4runner 22re. it was running so smooth but had bad battery. I haven't started engine for 3-4 months and decided to replace new battery. It starts engine after i replaced battery and then dying with 400-500 rpm from 1k rpm. i decided to drive the truck and it normally, smoothly drive. pull over and leave engine on and it is dying and going to dead. I couldn't find any wrong, is it from battery? or other?

Hope yall can help me out!

 

Fuel filter? If you haven't changed in awhile its a good place to start.

 

Definitely not fuel filter because i drove truck and it was running smoothly. it problem when truck parked and leave running engine on. it wont last long

 

 

Whats voltage when its running?

 

Thanks! it was battery! I got new battery and it's running smoothly now
