My 4runner cranks for 5-6+ seconds before starting in cold weather. Ideas?

[tomhaney1]

Ok, I don't get this problem. At this point Toyota should just start from the ignition and work their way to the crank replacing parts. This is ridiculous.

Any updates ? did replacing the starter fix the issue?

The starter system cranks the engine before ignition to get the oil moving a bit before it turns over.

Its to reduce wear on the engine.

If you go through the entire thread- a lot of the guys here believe this is excessive and not normal for this engine.

I just wanted an update from the OP

Well it is on the V8.

Only rarely in very cold weather does my 07 SE take that long. This sounds from the vid that this is a fuel delivery issue.

Sorry I forgot to update this thread. They said they found the fuel pressure dropped as the 4runner sat cooling down. They replaced the fuel pump and it's been fine every since. It still doesn't start up as quickly or strongly as most other cars I've owned, but it's at least not nearly as bad as before. I used to own a Lexus GS400 (Toyota V8) and it never was the quickest startup either.

We'll see how it behaves as we enter another cold season, though, but there was a night and day improvement when they replaced it, and it was cold back then.

No idea why a different grade of fuel would have any difference UNLESS you are using Arco or some cheap brand. Use a brand of gas like chevron, mobile or shell that has some kind of cleaning agent in the fuel. IMO.

But It should be a Battery/starter issue.

for once I may have been right :naughty:

Accdg to the youtube video, it could be anything. Check your battery posts if they're tight. Or maybe battery needs recharged/replaced. If you haven't changed your spark plugs in awhile, replace them. Pour some injector cleaner (i use B&G) or maybe your gas has some water condensation. Pour some Heet in there. On the side, check your air filter and clean MAF sensor.
Just my 2 cents.

It took you until page 3 though. According to page 1 you and several other members still owe me some beer.

You may be correct on the brew question however it occurred to me originally (and dare I say eons ago) that you wanted to start simple and the fuel system was pricier than a battery,,,(?). that being so you may want to consider the following ratio

length of time since 1st post in days (+) number of posts (-) money spent on fixes that did not work (/) cost of gas to take vehicle to dealer (x) number of itms thrown around the garage in frustration. sub $ for #.

If you calculate this and the cost is <$20. the beer is yours. If cost is >$20. beer is mine (ours)..... :bigok:

glad its running well.......now comes winter.:driving::lmao:

Threxx,
your warranty is from a third party (but affiliated with Toyota and the paperwork is made to look like a Toyota warranty).

Dealer must call the 800 number on it and negotiate for them to provide a credit card for the repair. took several repairs before I got my dealer trained.

sometimes it is hard to get through on the 800 number, or so the dealer claims...

You are not in the Toyota computer at all.

your right about that. You almost have to have the paperwork with you so they can call.

The fuel pump does not operate untill the engine begins cranking. Fuel pumps have a check valve that maintains fuel pressure when the engine is off. If the check valve is faulty fuel pressure bleeds off and so the reason it takes longer to start is the fuel pressure has to build.

wrong! fuel pumps turn on briefly prior to cranking to create line pressure.

in the op's case it was the fuel pump
