Help toyota won't start!!!!!!!

97 toyota tacoma 2.7 turns over but will not start. Has fuel has spark,timing is right on,sounds like it has no compression. Changed oil a day or two before problem started. Was turning over fine for a couple of seconds when I tried to start it and then just wouldn't start sounded like it had no compression any ideas I am stumped!!

 

Vapor lock maybe?

 

What was the outcome, this has just happened to me?

 

What do you mean by "sounded like it had no compression" ?
Did it turn over unusually fast while cranking?

 

I don't want to answer for mini, but for me it sounds unusually smooth, but I haven't yet tested compression, but if compression were low I know mine would spin much faster.

 

yeah if it turns over easily and really fast usually thats compression, id check that first.

 

So I found some talk about flooding, didn't know that would happen with EFI, but after holding the pedal on the floor for a min it started in a big puff of black smoke, and seems fine now.
I guess I was over thinking things

 

i had one do that to me..i think it washed the cylinders with gas and it sounded like it didnt have any compression.held it on the floor and finally it started and smoked for a min...never did it but that one time.
