It sounds as the voltage regulator which is built into the back of the alternator has stuck. Occaisionally this even happens on new ones. Would suggest taking the alternator back as it shoud be under warranty.

Spray some starting fluid into the throttle body. If it starts then you have a fuel problem. If it does not, then check to see if you have spark to the plugs.

Check the wiring going to the coil. If you installed an alarm on that vehicle disconnect the main power wire to the alarm to disable the ignition kill circuit. Locate the ignition relay located on the drivers side fender wall or in the power distribution box under the hood and test it. finally, there is a fuse on the interior fuse panel that will give you this condition. I do not have the exact location so check all fuses in the panel and replace any blown fuses.

The ecu has to energize the relays that send power to the fuel pump and injectors. Until that check engine light comes on, no power will be sent to the relays, thus no start. There are a lot of posts on this site about this, called the delayed start check engine light problem.

Guess what?, there IS NONE. it only has and ORIFICE. and sure it can clog, and does, in fact i drove for 500,000 miles in 3 jeeps. and cleaned it vast times. on one car , the grommet got old and it the orifice collapsed. and i had to buy a new one from jeep. see word FIXED below.? when it clogges, the engine leaks oil and the oil pukes (backups) and dumps oil on the air cleaner. there is no PCV valve, on this engine. but that dont mean its service free.

It is in the main fuse panel ?? are you sure it is a fuse problem not the reverse switch itself ? or one of the bulbs out ?
