Engine fired then died.
Guys.....Need some help!
It's about 20 degrees here this morning.....Went to the garage to start 4R with 160K and planned on letting it warm up. Got in, turned key...engine started for about 2 seconds then died...kinda sounded like a stuck choke would the way it died.
Now when you turn the key, it sounds like there is no compression...motor turns over fine but nothing happening? The only thing out of the ordinary is that I was working in the garage all day yesterday with the 4R parked out side. Brought it in last nite at 10:00pm from 14 degress outside to 50 degress inside and it was about 28 in the garage this morning. I'm wondering if the timing belt broke or slipped a tooth? It's only got 40k on it since replaced. Or posibly fuel line freeze up?
Any ideas? Need help fast...gotta work tomorrow and this is my only available vehicle!
THANKS

It's not real hard to get under the top plastic cover for a glance at the timing belt if it's the 3.4.
Got spark?

Where did you put the ether?
Try cranking the engine for about 30 secs then pull a plug and take a whif, if you smell gas then fuel si not the issue. Next check the fuses to see if you blew something (esp since the truck started and then died after a short time). It would also be good to check the cam pulleys to be sure the timing belt didn't let go. Let us know how you do with those.

Where I sprayed ether.??...I Pulled off the boot and flipped open the throttle plate and shot ether in the intake.
So far...I have drained the radiator and pulled the cam belt cover off....turned it over and belt spins...not broken. Also seems tight.
Will check fuses...then gonna pull a plug and check for spark next......

Ok....pulled plug on front drivers side and got spark and smell fuel. Checked the underhood fuse box and all fuses you can look at are fine.
I'm out of ideas.....other than possibly timing belt skipped a tooth.....anyway to tell without tearing the whole thing apart?
Anybody??????

I would try a compression test if you have one handy. Do at least 2 cylinders to make sure you're getting proper alignment on the timing belt. You could also pull off the front cover and verify that all the timing marks line up (ie both cams and the crank at 0 degrees / TDC). If you have all 3 (spark, fuel and compression) the engine should fire.

She had let it sit for a week in much colder than normal temperature (26F), after draining the oil, and not refilling it until just before starting it in the cold air. The extra friction caused by the colder than normal temperature, and the fact that the oil had drained from the cam area, caused the problem (imo). Plus she was probably running a heavier oil than she should.
Timing belt had about 10k miles on it.
Diagnosis was to pull a plug, notice the wet plug and the piston movement when cranked. No sound of air exiting the open plug. Stuck a compression tester on it for good measure.. zero, not a flicker.
On top of all that, the 944 is an interference-engine. Be thankful yours is not.

Pulled the cover....all 3 marks are lined up. Just talked to a local 4R mechanic and he told me that there has been a rash of water in the fuel at the local BP station......which is where I got my gas last time. SO, I'm gonna crack open the fuel line at the frame filter and blow the fuel both out the engins side and back into the tank....hope maybe that works????
Compression has to be ok if TB is ok, although you didn't check it... or even for a "whoosh" with the plug out. You had the sense that it was free-wheeling when you cranked it. Doesn't quite add up. More info

This exact problem has happened to me after letting my truck sit for a few days in the cold (20F). Both times it was parked immediately after a long pull on the highway, I was living about 2 blocks from the interstate.
My solution? Crank it with your foot on the floor for about 20-30 seconds. Mine sputtered to life and ran fine. Its happened twice in 3 years. My theory is that the gas tank and fuel system lost vacuum.

I'll try words.. its easy to find and get to. On the intake manifold casting, on the passenger side, there is an imbedded TOYOTA in the casting. Come back with your finger from the second O while standing on the passenger side, and you will hit the CSV.
You can verify it as it will have a fuel line coming in from below and to the left, and a connector standing above the plane of the intake manifold.

Looks like it was bad watered down gas........Ended up pulling the tank and draining it, then cracked open the fuel line on the engine and sent compressed air to clear out the entire line. Filled it with fresh fuel and dry gas, hooked up the battery charger and after about 25 - 30 seconds of fast turning over it started!!!! Now I just gotta go buy some anti-freeze and put it all back together!
Thanks for all your help!
