SOURCE: 1999 Chevy tahoe will not start

check the crank sensor. no signal from the crank sensor causes a no spark condition. best way to check is to put a scanner on and check for rpms.
the crank sensor is differnt from the cam sensor

SOURCE: My chevy express van 1500 cranks but wont start

test and see if you have spark and fuel preasure, you may have bad feul pump, common problem is the fuel pump goes bad, but check before replacing.

SOURCE: i have a '97 chevy tahoe. the engine cranks, but

What you need to do is check for fuel pressure.The pressure should be 60-66 for central sequential fuel injection and 56-62 for sequential fuel injection.If pressure is good then check for spark at the spark plugs.If you don`t have a way to check for fuel pressure then tap on the gas tank bottom with your foot or hammer while someone is turning the key and trying to start the vehicle.If it starts then replace the fuel pump.If this is good then check coil and ignition module if you are not getting spark.Hope this helps.Good luck.

My question what is the problem of bmw car 5 series engine wont start but has cranking?someone pls give some advice


When were your spark plug wires last changed? And have you checked your ignition module? Crank shaft position sensor is another item to have checked.

Will not start. Fuel pressure ok, new plugs and wires. Turns over, wont start. What to check next?


Check for spark at 1 or more plug wires. If no spark, possible crank sensor/computer/fuse/wiring. Check for injector pulse. Remove 1 injector harness and install test light between the two terminals of the harness and crank engine. Test light should flash if computer/wiring ok. Make sure check engine light comes on when key in on position for bulb check. If no light, look for blown ECM fuse/s

Tahoe wont start, cranks tries to fire


Sounds like a fuel delivery problem. Has the fuel filter ever been changed? You can try banging on the bottom of the fuel tank with a blunt object ( hammer works ) while some one cranks the engine. If it starts suspect a bad fuel pump

Did you visually check for spark at the spark plugs, engine cranking? Does the dist rotor turn when you crank it? Did you use a gage and check correct fuel pressure? Any applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader.

If you have the spider fuel system, that system is noted for problems. No, the fuel system shouldn't cause a no spark. If no rpm signal, that will usually stop the injector pulse along with other issues.

My 98 tahoe will not start


You mean when you said it tries to crank but didn't, you mean start right. It did crank ok just wouldn't start?
Sounds like it could be a bad fuel pump or clogged fuel filter. You need to check to see if there is spark. Pull one of the spark plug boots off and put a nail, paper clip, anything you can inside of the boot and put it on top of your engine and have someone turn the engine over to see if there is spark to the plug wire. Let me know back what you find out.
