truck won't start when it's hot

My truck starts in the morning. When I leave for work it starts right up. It's when I get home, it'll sit for about 10 min to 15 min. Then I'll try to start it up and it won't start. Changed the fuel filter, spark plugs, coil, air filter. All the small stuff. Love my Tacoma! It has 235000 miles!

 

Is it a crank/no start condition, or a no crank condition.

How old are your starter and battery. Battery condition (voltage while starting). Use to have that same issue with my Chevy LUV with a 383. Older starter would get hot while driving and couldn't turn the motor over no matter what battery I put in. With my '40, I had some battery issues that caused it not to have enough to turn a hot starter, but did fine when cold or with a jump.

 

Could be fuel injectors. They are known to leak on our older trucks with residual fuel pressure and flood the engine after it has been turned off. Then if you try to start it soon it floods and won't start. If this sounds like the problem I think the pink injectors from 01-04 are supposed to be better, but you should do some searching on the topic first.

Could be other things too.

Look at post #162. Solved my problem and hope it helps.

 

It cranks ok I guess. But I have been told that it might be the mass air flow sensor. What do you think?

 

Look into what the others said.
When you crank it hot, can you smell raw gas in the exhaust?

 

Thanks guys! Ill try cleaning the IAT & the mass air flow sensor. And see what happens. I'll let you guys know. Thanks again

 

Battery is fairly new. And when I try starting when hot, I do smell gas, while pumping the gas pedal slightly.
