Truck is hard to start, shakes and strong smell of gasoline

Greetings everyone justed joined this group. I own a 16 taco trd sport just under 100k miles. Recently the truck is sometimes hard to start, when the truck is warm idling at low rpms at red light. It's performing unsual shakes sometimes very noticeable, the whole truck going back and forth feels like it’s going to stall out. But when driving everything is normal even reving it up. No signs of drop in fuel economy. Also a recent oil change I can smell strong gasoline when it began to pour. Brought to the dealer today, they said the battery and spark plugs are good. They mentioned something to do with fuel line pressure which they need further diagnostic. Anyone has this issue before?

 

Fuel filter?

 

A lot of great information from a Toyota Master Tech with over 10 years of experience. Go to You Tube and search for the "Car Care Nut". All he does is Toyotas.

 

Ima looking into that

 

It could be

 

I assume you had the crankshaft recall issue repaired? That is a very old recall from 2016, but checking just in case.

Toyota replaced the faulty crankshaft sensor with a new one, that lo and behold works.

Failing crankshaft position sensor can affect idle, acceleration, cause stalling, misfires, vibrations etc.

If you are not sure, have your dealer take a look at it or the vehicle repair history to make sure it was changed back in 2016.

Fuel pump can also cause the issues you are having.

 

Sounds like the spark plugs to me, were they ever changed

 

if you have 100k miles and never replaced the fuel filter it may likely be that with all the dirty fuel there is. That plus old spark plugs as another mentioned could certainly be giving you all the trouble.

 

I agree with this.

 

The fuel filter is an in tank filter and is designed to last the lifetime of the vehicle.

 

You are probably right about the Toyota fuel filter, however, this makes no sense, logically. Filters are designed to trap dirt. Dirt eventually clogs a filter. Maybe if you run 100% clean fuel, then maybe, which is impossible. But maybe toyota has figured out a way to filter our dirty fuel and still keep the filter clean.

 

Here is more information on the Crankshaft Position Sensor recall.

Toyota and other manufactures have been doing this for a long time. Very few filters are changed.

 

Yeah, they are gambling on the use of fairly clean fuel.

 

I just checked for recalls. It looks like the truck has no open recalls. Could the crankshaft position sensor fail again even it's been done?

 

Sounds like a general maintenance item to me. Good luck Op.

 

You misunderstood. he said the filter lasts the life of the vehicle.

That means if the filter is done, it's time to toss the truck and get a new one. /S

 

Updates on the truck. Dealer charged me 2hr of labour for diagnostics. Told me both fuel pressure regulators went bad and need to be changed. Quoted me 160 for parts and 2.5 hrs of labour to get them replaced. That's is really expensive I'm not sure if I want to bring it back to the dealer..

 

Nobody works for free. Time is money. Some people may work chepaer than others. In the end, if you need the truck, get it fixed. There are other "costs" involved.

How much "more" will you spend trying to find someone to do the work at a lower cost, and acquire the parts...
