TOYOTA Cressida just stopped running!

[college man]

since its a carburetor. remove the air cleaner open the flap
move the throttle linkage a couple times to see if fuel sprays
into the carb. better yet. spray some starter fluid in the carb
to see if it starts. if it does then its a fuel issue. either the fuel
pump is not working or the filter is clogged again.

This is a great place to start if I’m honest, keep us posted.

Thanks guys for the really fast responses. I really appreciate it 🙂

After consulting with my father, he told me to check the inside of the distributor. And I was amazed by the fact that a gap as narrow as 0.5 mm can stop the engine and prevent it from running!

I actually don’t know what’s it called, but after removing the distributor cap, there is what I call “the hammer”, which is sitting on the central shaft. The shaft has four rounded corners, so when the engine runs and the shaft turns, those corners would push an arm back and forth, opening and closing a gap.

What I found is the gap was always closed, so what I had to do is re-adjust it to be opened 0.5 mm, and that fixed the issue.

This also caused the engine to be a little bit high at idle, but I think I can fix that by re-adjusting the carburetor screws.

Thanks for the update!

[college man]

glad you worked it out. thanks for the update.Cool

[abuthabet87]

I had another issue, and I think it is because I have a crack in the exhaust muffler, just at the very end of it.

When the car is in idle, the engine is nor stable and smooth. Instead, its rpm decreases slightly then rises back to normal. This happens at a rate of approximately one decrease per second. And when I put my car in first gear then raise my foot off the clutch pedal slowly so the car will roll on its own without hitting the gas pedal, the movement of the car is not smooth. It jumps and leaps every second!

[college man]

does it jump in every gear or just first. heres a video to help
if its the clutch or not. a muffler crack should not cause a idle issue.
unless its by the 02 sensor.

Glad you got the points figured out. As for the ‘surging’ with a carbureted engine this can be tricky but I would first check for vacuum leaks as that’s a great place to start in situations like this.

[abuthabet87]

It’s not the cluch. I put it in 5th gear and it immediately stalled.
As for the vacuum leaks, I doubt I have any, but I’ll check for them. But I almost got this fixed by adjusting the carburetor mixture screw to allow more mixture in.

Thanks guys for the follow up. You’re the best 🙂

[EricTheCarGuy]

If you adjusted the mix richer and it got better it’s likely you have a vacuum leak. Once you find it you’re now going to have to readjust the mixture screw. Be sure to check around the base of the carburetor as leaks are common there, sometimes it’s not the gasket but rather the throttle shaft that’s worn out so be sure to check there too.

[abuthabet87]

Thanks Eric, that’s a good idea since that mechanic had removed the carburetor and re-mounted it, if there is vacuum leak it will be there.
I’ll check for it tomorrow and update you.

BTW, if I found a vacuum leak at the base of the carburetor, should I remove it and try to mount it correctly? and is it safe for me to do it by my self? I’m not a mechanic, but I know how to loosen bolts 🙂

If you can make a video about carburetors, that would be great 🙂

[dreamer2355]

If you do have a base gasket leak, just replace the gasket yourself. Take pictures and take your time if its your first repair C8-)_x000D_

Or see if you can find a service manual for your vehicle.

[abuthabet87]

Let’s just hope it’s not the gasket, as I’m not sure if I’ll find easily !_x000D_
Thanks alot dreamer2355 for the follow up._x000D_

I’ll try to take pictures along the procedure and post it here,

You can find from here easly http://www.rockauto.com , buy from internet, they will send to you via fedex, you can see on your hand in 2 days.If you sure your problem is a headgasket.

[EricTheCarGuy]

If it’s leaking replace the gasket as it’s a common failure and I doubt remounting it would reseal it.
