Toyota car and truck forums

I have a prob with my 92 toyota truck. used "seafoam" to clean out throttle body.
smoked and knocked pretty good, then quit. upon trying to re-start it fires momentarily, then quits. I had my wife start it, while I used some
flammable lubricant into the throttle body, to keep it going.
I'm thinking that the injectors arent being told to open up.
any comments/suggestions?

Do a quick compression test and pull the plugs and read them - make sure you dont have a problem like a bent valve or similar.

As for injectors - you can stick an automotive stethscope on them and listen for the ticking sound. You can also use a long screwdriver - just be careful.

Also check the knock sensor - didnt mention the engine, but most are between the middle cylinders (#2 and #3 on 4 cylinders, #3 and #4 on inline sixes, one on each side for V6s).

Hopefully, didnt hydrolock the engine - pretty hard to do, but I've seen it happen. Good Luck.
