Ok, I need help from anyone that is a SC300 expert, My car Died on me this morning on my way to work a block away from home( thank god) It cranks but it won't start, I can def smell fuel & it seems like its not getting spark...
Please help me I'll appreaciate it & Lunch will pay for...

 

you said you smell fuel. definitely check your fuel rail and fuel lines. check your cap and rotor. and plugs. and get back with me with the feedback

 

Did you post this in the SC section

 

You may have a bad fuel pump as well. I would work with checking the ignition system first. Process of elimination is key.

 

Well the car started right up last night, This morning too, It started right up & left the car running for 2 hours, I drove the car to work & nothing, Has anyone ever had a similar situation like me before?

 

i used to work at a murray's and we have on-car starter and alternator checks. so you can bring your car to any murrays and have them do a free check on your car.

 

How old is the battery?

 

It's a 93 SC300, I doubt there was anything wrong with the altenator or starter..... I believe it was ignition or fuel related...

 

Battery is brand spanking new.... I drove the car today to work, No problem, I just met a guy today with a SC300 & he thinks its the mass air flow sensor acting up........ Well hopefully i doesn't happen again

 

if your battery is new, check the pos/neg clamps. clean it with a wire brush and scratch the battery post too. make the are tight.

if thats good, check that your power radio antena is draining your battery.

if thats good check your fuel filter, it may need to be replaced.

check the other end of you battery cable too. pos will go to starter, neg will go to your frame/chassis groud. check they are snug and have good contact.

hope that helps some.

thse were my problems with my daily driver 1st gen gs300.

 

I don't have a draining problem!! The car died during running & it just cranked & cranked & cranked but never turned on!!! The car sat for a few hour & it started right up like always... One of my friends just told me it might be the Mass air flow sensor Or the Fuel filter.... Well so far soo good, Car is running without any problems...

 

My guess is spark plugs. The other day when the car died, it was a colder morning. Now that the weather is warmer, it's starting up with no hesitation. Pull a spark plug from each bank...I'm willing to bet they're fouled up. The fuel you smell is probably what's sitting in the cylinders going uncombusted.

If it's an alternator issue, you'd have issues with misfiring, lumpy idle, and then eventually no ignition at all.

If it's your battery/alternator, look for other symptoms like dimming gauge cluster, headlight brightness dimming dependant on engine speed.

If it's your fuel rail, check your temp gauge. The engine could start running hot if the motor isn't getting the fuel it needs.

If it's your MAF sensor, you'd notice a big change in how the car accelerates when it's cold.

 

Also, search on fuel pump ECU in SC section, and how to bypass in case it does it again. I believe when it overheats it stops to work..

 

Thank you...

 

It did it again!!!! I think it's the Fuel ecu, I switch igniter, The coil, NOthing!!!
It started after 15 minutes of seating down.. It turned off again after 5 minutes... can someone please post where the fuel Ecu is located.. thank you..
