Hi Anonymous, and the usual suspects are:
1. Loose, corroded, or broken battery cable ends inside the cable harness especially the "NEGATIVE" cable at both ends.
2. A severely drained battery.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

My 1987 jeep cherokee pioneer will start but then you drive to the store come back out and it will not start until it sets for 5 or 6 hours..


You may have a faulty ignition coil. Check to see if system is firing when it won't start. If you have fire it is probably fuel pump.

2000 nissan maxima won't fire when trying to start. it turns over but won't fire. it started once and ran but won't start again


sounds like it might be flooded. Try and remove the fuel pump fuse from the fuse block that is just in front of your left knee. While it is out crank the car and see if it wants to start and hold down the gas pedal all the way and then relase it and back and forth and once you get it to run have the fuse ready in your hand and in front of the spot to install it. and then keep the rpm's up with the gas pedal until the smoke clears out behind the car.
