1998 4Runner 3.4l 4wd. 185k miles. 

Issue: Starting issues after driving but only 10 minutes after shutting down. Example: When doing the daily daycare pickup routine. Shutdown truck. Go in to grab kid. Come back to truck.. If Less than 10 minutes has passed since until shutdown truck starts up fine and runa perfectly. If more than 10 minutes has passed it's an absolute crapshoot as to whether it'll start without a quick shot of fluid. If starting fluid is necessary it starts and runs fine.

No obd codes. I use TorquePro.

Fuel pump energizes when 12v is put to it

New inline fuel filter.

Throttle body and IAC pulled and cleaned off truck. IAC valve tested good when bench tested.

MAF sensor tested good and good numbers coming thru on live data.

TPS checks good.

Injectors pulled and cleaned of the truck. 4 port not 2 so I'm assuming the previous owner had them changed.

Circuit open relay tested good.

O² readings seem ok.

Not out of timing. Timing belt new as of about 5000 miles ago. Done twice because of factory defect in the first belt.

next step is pressure test but I'm waiting on banjo fitting to come via Amazon so I can rig up a pressure tester.

Thanks, hunter
