98 runner / long extended crank after sittin more than 2 days !!
Strange problem with my 98 runner..!!!, If it sits 2-3 days without being started, it takes about 10-15 seconds to start....It just cranks its ass off and eventually will fire up... Its all stock with no cel's and runs fine otherwise...It will fire up fine if it sits only one night...It has 141k on it and purrs like a kitten otherwise... Any ideas??? I just dont eventually want to get stranded anywhere......thanks

Yeah, I will give that a try...I thought it may be a weak fuel pump or something....

I am not sure how the fuel pumps are rigged in toyotas, but it could have a bad diaphram or check valve? My 92 is slow to start after sitting for more than 3 days, probally the same thing... I dont ever worry about it.

Here's what you could try, after sitting a few days, take the gas cap off and listen to the filler neck while someone turns the key to the run position. What your listening for is a hummin sound that will probably go on for about 2 - 4 secs. This should happen everytime you cycle the key. ( listening to an end of a hose in the neck will amp the humming)
If there is a hum then the fuel pump is working if the pressure is w/in specs, most likely it is if there is amply power when you step on it while driving. If this isthe case, then most likely I cocur with AH64ID that it's a check valve problem . (The fuel lines are loosing their prime) Most likely it is intergreted in the fuel pump.
If you don't hear a hum then there's a control problem related to the ECU and F/P relays. Good luck
