Try checking your cam sensor and crank sensor. You can test them with a voltage meter. Many times, the sensors will go before anything else. It may be your distributor itself. Test it as well. If you have a question, please let me know. I am here to help. Thanks for using FixYa. Have a good evening.

Thanks for choosing Fixya and welcome to the site. As far as fuel, it is either the fuel pump, filter, fuel lines, or the injectors. Check your fuel pump fuse, relay, and reset, if equipped. You should hear the fuel pump kick on when you first turn the key. Make sure the fuel filter is not clogged and check the fuel lines for damage. Lastly, check the fuel injectors for fuel. As for the fire, have you checked the cam sensor? Some computers cut off fuel and fire, for example, if the fuel pump was down. If that is not the case, you probably have an electrical issue. It may be your computer. Check your timing belt/chain as well. It may be out of time and the computer may not be reading it. If it is electrical, you will need it put on a machine. If you can't, you will need to check all wires and current in the ignition system to see what is not getting power. If you have any questions, just let me know. Thanks for using Fixya.

Check for spark at any of the sparkplugs.If there is no spark at the plug then replace the distributor ignition pickup coil.

Y is my 97 chevy only fires on the number one cylender

if you have fire on the number one cylinder,it means that the ignition coil is working so your problem can come from spark plug wire or cap and rotor . unplug the wire from ignition coil to distributor and check for fire you are suppose to have fire because you saying having fire on cylinder one. from there change cap of distributor and rotor plus a set a spark plug wire.

What's your problem?I did all these changes to my 1999 Dodge Durango. They are distributor cap, rotor, wires, spark plugs, and pick up coil. My fuel pump is working I also check the alternator and it...

Check that the crank shaft position senser is plugged in and working and not broken this will cause your comp to not send fire to you coil and it won't fire hope this helps you

Truck wont crank. we have put new distributor cap, rotor button, coil pack, plugs, wires, and fuel pump. we also checked our firing order.

you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.

Changed distributor cap now car will not crank

You should check to make sure that the rotor button is in place. Also check the coil wire and the fire orderr to make sure that no wires are crossed. These are pretty much the only reasons why your car won't crank with the distributor cap change.

1997 jeep grand cheerkee tunes over but won,t start no fire from coil to distributor

So you have B+ to coil but no B+ from coil to distributor. Sounds like the ignition module.
Its not triggering coil to fire . Double check it with a test light at negative side of coil and then to ground.crank the vehicle if light flickers its ok if not its your culprit.
Should light flicker then test its the wires from coil to distributor, distributor , rotor and plug wires.
Honestly if the light flickers your not losing anything by replaceing the items from the coil tower to the plugs.

No Spark

The " FIRE" doesnt come to the coil from any of those things you have changed.......The "fire" comes from the coil TO those items!!!! Good luck, RC
