Car won't start. Need to locate Crank Sensor. Help!
Three times after towing to the shop for not starting, the car would start right up. I seen at this site someone recommended checking the crank sensor. What is it and where is it located? is it something a back yard mechanic with light skills should undertake

your first problem is that you are taking it to a mechanic with questionable qualifications
engines don't clear throats or have relays do it for them
the car has an onboard reporting system called an ECM and any mechanic who knows his trade would connect a scanner to the data plug and read the fault codes ( you can do that at autozone or like spares shops for free)
knowing the fault codes , the faulty sensors can then be fixed or replaced
from your description of the problem it appears to be a cold engine problem as you say runs well for the rest of the day
That indicates an ambient temp sensor, Baro sensor, MAP/VAF sensor and low fuel pressure from a faulty fuel pressure regulator sensor problem
find yourself an accredited service center that has experience on your make of vehicle and have it properly diagnosed
You basically had a intermittent problem,If anything it probably was not the fuel pump, In order for the fuel pump to turn on the ECM, needs to see a crank value, of 250 RPM or the fuel pump will not turn on, what gives this it is the crank sensor,The crank sensor does age and when it goes out you can be driving down the freeway and all of a sudden the car stalls,and it doesnt start up,
mcdevito75 here, BEST BET, let the shop do this work, too many un forseen problems could come up. The stalling and unable to start for a while could also be a bad ignition module, no test for this part, but I would have it changed, for if it is a bad ignition module, all this other work will not fix the stalling and later start of your car.
maybe there is some teeth missing on the timing belt. when it turns sometimes it catches the teeth and starts. but when it doesn't catch the teeth it won't start. have seen this problem with some cars need to take apart timing belt cover to find out
I had this problem in my shop and its been a Crank sensor and on one occasion it was a fuel pump relay that was bad. Most like its a the cranks sensor that's bad NOT the fuel pump relay but check both. To check see what missing when vehicle doesn't start or shuts off . If there is NO gas its the relay. If there is NO spark its the cranks sensor. Good Luck and contact if you need more help. Thanks for using FIX YA
