IF THE CRANK SENSOR GOES BAD ON THAT ENGINE THE CAR WILL STOP RUNNING OR NOT START IF TRYING TO START IT. NEED THE CODE INFO TO HELP YOU FURTHER. TRY GOING TO ADVANCED TO GET THEM TO READ THE CODE-THEY DO THIS FOR FREE.

SOURCE: check engine light

Check all of the connections to the ECM--twice.

Be sure the four-letter code on your replacement ECM matches the one you removed.

The ECM relies on calibrations performed on some sensors while at the factory. For that reason there may be a switch or a sensor that is reading out of range.

If it seems to be running fine, drive it for a while and get an accurate measurement of MPG. Poor MPG will indicate that things like O2 sensor, MAP/MAF, TPS, IAC, IAT are not reading properly. Check for codes with a OBD-I reader.

SOURCE: car shuts off when it gets hot

your ignition coil are going bad, they need to be replaced. once the car gets hot the circuit shut down the car when hot. once they cool your riding again until they get hot. thats your problem. Good Luck

97 tacoma runs a few seconds and dies. will stay running if you keep foot on gas for a few mins then let off. crankshaft sensor code, replaced it but still get code. could it be iac or tps

If the code for the crank sensor comes back, then there's still a fault in that circuit. Check for sensor resistance and wiring harness short or open. Crank sensor resistance should be 1,630 -2,740 ohms when cold. TPS would not cause those symptoms. IAC could cause rough idle but wouldn't affect higher RPMs. Bad coolant temp sensor could also be part of the problem. Bad sensor = ECM thinks engine is warmer than it is and provides too lean a mixture. But fix the crank sensor issue first since that affects the fuel injectors.

My Buick Rendezvous now cranks but wont start no matter the temp of the engine or outside. Replaced the ECT sensor and it worked for a while but now refuses to start at all. Jumping it doesn't help.

Hello,

The first thing I think is the 'coil' the second thing I think is the throttle position sensor (TPS). Some sensors will not throw a code as they are pre-ignition sensors (TPS). Press the gas pedal to the floor and start the vehicle - this will bypass the TPS. If the vehicle starts clean or replace the TPS. If not you may have to replace the coil pack or coil(s) but test them first (ohm with volt-meter - book should have specs).

I hope this helps

That is a possible cause alright. I would get a can of fast freeze spray from a motor parts factor. If its ok when cold but shuts off when hot its very likely.when the engine shuts off, spray the crank sensor and immediately start engine. If it starts and stays running its your crank sensor. Does it have a duel mass flywheel?? Some times if the crank sensor picks up off the flywheel and the duel mass is worn , it then runs out of sync with the cam shaft pick up sensor, which will cut the vehicle off. Just a shot in the dark? If you can drive vehicle when cold , check for vibrations whilst engine is cruising at steady speed. You will not feel vibrations under load. Keep us informed on how you get on.

Check the ECM if it has the number 1228253 that is your problem, these ECM's will give a shutting off problem. Get a used 16198264 and that will fix it. Buick dealer secret info.

if your fuel pump is functional at time of failure another common problem is the crankshaft sensor located behind the crank pulley a scan tester can identify if this is the cause in datastream of the scanner watch for a crank signal while cranking engine over

Car shuts off while driving

if car shuts off while driving it could be a bad crank sensor. a bad crank sensor will shut car off while driving, then it will not start for about 10 minutes, when it starts it runs fine until it goofs up again. the popping could be the sensor for it controls timing along with the cam sensor.

Runs fine for approx 15 mins,then stalls out and wont start again

sounds like coil problem, coils will start cold then get hot and stop. when coil cools will crank up and run till it gets hot, try to replace the ignition coil,dont think it would be a crank sensor, try a coil,thanks robert b.
