My 1999 Chevy Tracker dies sometimes when it gets hot and also wont start after it gets hot. Someone said maybe the crank sensor some say maybe a relay of somekind. I am just wondering should I replace the crank sensor and if so where is it?
It is the Camshaft sensor, I have a 2003 tracker with the 2.0 liter engine. I replaced the cam sensor, and it did the same thing, died when hot, then wait 15-20 minutes and it would start again. There are no codes stored in memory, UNLESS you read codes when the problem is occurring, then it sets a Camshaft code, but clears itself when the engine starts. So anyhow, since it died after replacing the cam sensor, I figured it was the crank sensor, so of course I pulled the transmission and replaced the crank sensor (bad spot behind the flywheel) It still died. I checked and rechecked everything I could think of, wiring, grounds, PCM and terminals, bought another Cam sensor, and it is still running!!! When it got real bad, I could push down on the sensor and get the car to start.It is the Camshaft sensor, I have a 2003 tracker with the 2.0 liter engine.

Re: My 1999 Chevy Tracker dies sometimes when it gets hot...
Chevys have an engine module in the distributor that acts that way when they heat up I had the same problem with my camaro look in to that before replacing Franco sensor

Go to Autozone or one of them and get the trouble codes read. Probably something there, maybe a crank or cam position sensor code, or also could be something in the ignition system like a bad coil or the ignition control module. The ICM controls the ignition coils' circuit, both of these two items can go bad and then fail when warmed up. Backfiring, shaking, and coughing kinda sounds like a bad crank sensor, but that's just a guess. Check for trouble codes first.
First key on you should hear pump run a couple seconds if you think it's the pump have someone crank it over and another pound on the fuel tank this sometimes makes the pump motor start to run, if it does that may be enough for you to drive to a shop for a new fuel pump.
Well the alternator won't have anything directly to do with an engine not starting. Only if the battery is dead because the alternator is not charging it. If the engine cranks but does not start, someone will need to figure out if you are lacking fuel to the injectors, spark to the plugs, or compression to proceed with testing.
if you have not changed the camshaft position sensor you need to do that sounds exactly like my problem got the new fuel pump and filter in there and it was fine for a month then same thing started happening again, been fine for 7 months since I changed my camshaft position sensor
if if the crank sensor has been replaced and still reads bad it could be a timing issue,maybe timing has slipped or maybe timing chain has broke.. remove oil cap and look down into valve pan while someone tries to start it. if rocker arms do not move then this would indicate timing chain or gears are broke.... hope this helps and good luck....please rate this post
Check your crank sensor. You might have an oil leak that is getting inside the sensor which is the reason why it wont start when hot. When oil is cold, its thicker so it leaks slower. Have a mech check it out.
