Wont start not getting fire to injectors a week fire to coil pack and when you press break petal a crackling sound in fuse box under hood

SOURCE: Fuel Injector Wont Spray

check wires at throttle body. can use a 12 volt test light to check for current. if you have spark it is not the ign module. set meter for 12-20volts. should have 2 fuse boxes on this model, one behind right side of dash at floorboard

ARE YOU CHEKING SPARK OFF THE COIL TOWER OR AT THE SPARK PLUG END OF THE WIRE SOUNDS LIKE YO HAVE A BAD WIRE

SOURCE: Tryn to locate the fuse box on a 1990 Pontiac Bonneville

GM fuse boxes are usually in glove box, on dash right inside drivers door, or under the column. Hope this helps

If you have a volt/ohm meter, you may want to first ohm check the resistance between the two spark plug towers on each ignition coil pack. Simply remove the spark plug wires from each coil pack and test. Both (if good) should test about the same resistance, (about 5-7 kOhms, but I don't have the exact specs handy on this particular vehicle. The reading may be higher, maybe around 7-12kOhms) but nonetheless, the reading of the 1-4 coil pack should closely match the 2-3 coil pack. If not, the new coil pack may be faulty and should be returned for a replacement.

Also, when you remove the 1-4 coil pack, take a look at the primary spade connectors (2 lugs) coming out of the ignition module. Make certain these are clean and free of rust or corrosion. If so, simply (and gently) use a finger nail file or 400 (or equivilent) sandpaper to file the corrosion off and re-attach the coil pack.

If one or both of these don't fix the problem, you may have to look at replacing the ignition module. But only do that after exhausting the other simpler and less expensive tests! :)

I hope these tips help you out or at least point you in the right direction! :)

SOURCE: changed coil pack that wasnt firing started fine

3.8 1999 firebird the 3/6 coil pack gets power but is not firing everything has been changed even the coil pack still sayin misfire
