My 2001 sienna v6 died out while I was driving down the road as if someone turned off the ignition switch. It did not sputter or anything. It just cut off. It only cranks now but won't fire up. I checked for codes and no codes are present so what should I do?
Do you
have the same problem?

Hi szalkuskt, Welcome to 2carpros and TY for the donation

You need to establish if its a fuel or spark problem-
If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems
with compression and valves opening and closing at the wrong time/broken or jumped timing
belt/chain

There are no plug wires so I guess I would have to take a coli pack out of the head and put a sparkplug in it and then ground it out to check for a snapping blue spark. Also where are the important fuses so I can check for to see if they are blown? Also, I need to get a fuel pressure gauge to test for fuel pressure, what is a good inexpensive kit to buy and also maintenance manuals on how to do it.

Do the spark test 1st then follow it with the fuel pressure check

Do you hear the fuel pump when you turn key On? If so do below

You hook up to the fuel test port on the fuel rail then turn key On and read the pressure.

As per the repair manual you can go to Mit1 . Com for a lesser cost.

The pump noise should be in the tank? Also what is a good fuel tester to buy, are all the sizes of test fittings standard on the rail?

Disconnecting the battery will make the computer lose some memories, maybe it relearned itself-Double check battery connection. Are you having troubles starting it up if not you're good to go. Its hard to say where this problem originates-The trouble part its intermittent and has to be catch right then and there if its fuel or spark problem.

What does flashing do and usually how much is it? Is it cheaper to buy a new computer? What do you think is happening that my computer might be kicking off the engine? Can this type of problem be other than computer related?

Next time when it dies out do below immediately don't disconnect the battery to fire it back up and come back with some results, in the event it dies out again bring it in

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

Well right now it is in the "no start " condition and I think I am going to tow it to the dealership on Monday while it is in the "no -start" condition and that way they can have a better chance of diagnosing it. Sound good?

If the iac is not working would it bring on a code? I took the intake ducting off today and try to start the engine and it would not start. Why did the dealer tell me the iac is going bad? Itnever produced codes

Ok I got the van to start then die. I hooked up my obdII scan tool to scan for codes and no codes but hen it would start and run, but run funny. Then I noticed I had the OBD II tool still plugged in and when I unplugged the scan tool the van died. Tried to start it back up it would NOT start. Tried starting the van with the scan tool plugged in and it started up but ran a little wierd and the temp gage would fluxuate up and down.

You need to bring the computer in and get it tested this is as far as I can take you thru the internet

IACV could be bad and won't give a code, don't always rely bcuz the CEL didn't read a code for the IACV that's its still good-try replacing it and go from there.

Are you thinking the computer is bad? Any reason why with the OBDII plug plugged in that it ran? Can I remove the computer and buy one and install it without going to the dealer? I have seen ecu exchange places on the internet. Remove the computer and take it in or drive my van to the dealer and play the dealership service department game again?I really don't have faith in the dealer although, I am going to change the IACV with a brand new one bcuz I ordered one already. Where is the computer located anyway?
