3rd gen Tacoma random hard start

Just being a smart ass.

 

I tried that before. People said "smart" is inaccurate but the other part is correct.

 

Replaced crank position sensor. No change truck had hard time leaving work yesterday :/

You check air filter, if clogged? At around 67,000 miles, the sparkplugs ever been replaced? If nada, time to change them out.

 

OP says it runs fine, except the startup. He has a fuel pressure problem.

 

Leaking fuel injector possibly flooding a cylinder, causing the hard start & smell of gas?

And on another note, I recently had a bad Catalytic Converter on a high mileage 4.0L Ford Ranger that would intermittently have a hard start condition and smelled rich. Replaced the Cats & O2 sensors without doing any ignition work, & haven't had the issue since. Just saying.

One of the occasions trying to leave work

 

The first time the issue occurred I did a basic tune up
Spark plugs, air filter, and cleaned maf sensor.

 

It sounded like it fired off briefly after cranking at first, then died & kept cranking before you stopped it. That seems to me like the ignition worked but truck may be flooded.

Maybe pulling the plugs after the truck has run, been shut off, & then has sat for a bit to see if any are wet, or trying a fuel pressure leak down test would reveal something. Perhaps even a fuel pump problem or TPS error of some sort.

Also, what do they use for Idle Air Control on these trucks?


Disclaimer: I'm new to these engines, so I'm really just spit-balling based on my leaky injector theory at this point. Based on my inexperience with this platform, I'll defer to the experts for troubleshooting procedure specifics, but will be watching this thread to see if you can get it resolved.

 

What about the throttle body, check it out if dirty? Maybe take your Tacoma to another Toyota dealer, or independant shop to solve problem.

 

Dropped the truck off at a different service center. Hopefully they can trouble shoot it. Will keep you guys posted

 

Update:
Dealership confirmed leaking high pressure fuel pump and replaced it under policy.
Got the truck back couple days ago and unfortunately extended crank is still occurring randomly :/ only difference is no gasoline smell now gonna drop it back off today

 

Original Battery? It may still start the truck but does funny things to it before it dies...
