He is correct the speed sensor is used by the transmission controller and antilock brake system the engine controller uses this sensor but not for starting purposes

    So....the first time this happened, it did crank but not start, we did try to jump it and that didn't work. It took us about a week to get to it, so we were going to tow it home and it started. Drove it that day, then the next day it wouldn't start again. Had it towed and that is when they changed the battery out. Drove it for a day and then it wouldn't start again. What would you try?

    there are too many variables to just spout off something are you able to do any basic tests or checks like check for spark or fuel pressure,compression

  • Brian Johnson Dec 11, 2012

    not to overwhelm you but the crank sensor ,cam sensor, or distributor , computer , fuel pump, wiring problems ,ignition switch and a host of other things could be wrong anything would be a guess without some basic checks like spark, fuel pressure

SOURCE: Hello. My 1997 Chevy Tahoe

Now you have a good battery & a starter that turns over the motor

Have you cycled the key on & off with a fuel pressure gauge on the
fuel rail?

Do you have a fuel filter that isn't over 3 or 4 years old?

Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance

If you removed the ducting & MAF Sensor it won't start

Tell us what you checked & exactly how that was done.

SOURCE: Car wouldn't start. Thought

did they run a test on the alternator!! at battery when off should be at least 12.6 volts, less than 12 volts battery is bad. when running at battery voltage should be at least 14.1 to 14.7, thats if alternator is ok. if less than above replace alternator. if alt. is ok, could be a bad battery.

SOURCE: car won't start. There was

I am the type that likes to jump start a car to troubleshoot it. If you jump start the car and it starts that tells you that the starter and engine is good and the problem is in your battery or alternator. If it doesn't start then I take the serpentine belt off and try to turn the engine with a large wrench. If it rotates, then I replace the starter and starter solenoid.

Sounds like your not getting any fuel..Listen for the fuel pump,by removing gas cap and put your ear up to it..cycle the key without starting it and listen for the pump..sometimes you can beat on the bottom of the tank and it will jarr the pump and it will start running again..Not a fix but a conformation

you may be getting fuel but you are starving the cylinders from it. after sitting this long, i would replace the injectors because they will corode inside after 7 years. agood injector cleaner might work but they are probably too far gone. you might have sent a lot of corosion from the fuel tank the first time you ran it & that will add to total shut down of the fuel injectors. also check your oil pressure, or it may jump on timing due to stiff cam bearings. depending on klts, it would be good to use slightly heavier oil grade. you may also want to check your ignition coil for proper supply to plugs. bin there, dun that.

I did not get all of your description. If the computer is saying the sensor circuit is the problem, it could be the connector at the sensor, something in the harness going back to the computer, or the gear in the transmission that turns the sensor.

It may be a bad ignition switch.

Also, It could be a fuel pump, remote chance. A fuel pressure test would prove if bad. Should have 40 psi of pressure.

Any warning lights on, on the instrument panel? Check engine light? Or, they come on after the stall?
