Try looking at spark from coil. Pull coil wire (hold with well insulated pliers or similar to avoid shock) and hold away from coil. crank it over and observe spark. If 1/4"-1/2" & orange/yellow color, replace it, if about an inch or longer & nice blue color, coil should be o.k. Appears that computer problems are not uncommon on these, so if that doesn't fix it, I would disconnect battery connections, pull computer connections, clean well with contact cleaner, add a little dielectric grease and re-assemble & try. Otherwise you may have to have computer tested by good mechanic. Remember, even though some people don't like going to a dealer, they are the most likely to have run into this the most, and usually know right where to look. Keep us posted, good luck.

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

No spark to ignition coil or spark plugs. we have replaced all spark plugs and wires cap and rotor down stream O2 sensor too.

The Cam & Crank Sensor controls whether the coils will give spark to the engine or not if you scan the computer it should give you a code for 1 of these sensors. They are very easy to change and are only around $50.00 each.

99 5.2 durango :pulled codes for multipe missfire cylinder #5-7

Aloha We have just replaced all of what you have replaced, plus water pump, fuel pump, pcv valve and 02 sensor. Took it to mechanic today we had misfire on 1,2,6,7. Mechanic said that the 99 dodge is known for bad computers, he checked ours and works great turns out that it was the coil. Ours was jumping 1/4 inch and had a orange/yellow spark. it is supposed to have a 1 inch spark and be blue. This has solved our problems after 527 dollars later.
Check the coil!
