My 99 only has 85 K and I cant fix it fast enough! I have had to have the trany rebuilt twice, replace the alternator, battery twice, idler arm, and of course I replaced plugs, wires cap rotor. The blinker constantly makes a clicking sound unless you step on the brake; Im sure I need to replace my turn signal. I have a loud humming from the front of the truck when I go over 30 MPH and it will go away when I stear left; probably wheel bearing but I dont want to take apart the hub just to find out everything looks fine. The dome light stays on all the time unless the dome light override is depressed and to top it all off and add insult to injury, I went to start it this morning and it wouldnt start. It will turn over and sputter occasionally, both sides receive spark and I can smell the gas in the exhaust. I did the searches and it looks like it could be the coil but Im stationed in Germany and I must order the part. I want to be sure before I wait two weeks for it to get here and find out thats not the problem. Any advice anybody can give would be appreciated.

The constant clicking of the turn signal relay, is most commonly caused by the multifunction switch (Wiper/turn signal). If this is the cause it requires replacement of the switch. Ocassionally the problem is caused by a weak relay, and can be fixed by simply replacing the relay.

The loud humming could also be something as simple as a bad tire. The typical signs of a bad wheel bearing is a load growl accompanied by a vibration that gets worse while turning in one direction and disappears while turning in the other. If the wheel bearing is the cause of your humming, the symptoms going away while turning left, indicate that it is the one on the driver side.

The dome light problem is most likely a bad door switch.

As for the no start, most no/hard starts are caused by fuel pressure problems. Before replacing anything, you should check your fuel pressure. The pressure should be:

Key On Engine OFF (during the intial 2 seconds when the fuel pump is running - 60 - 66 psi

Key On Engine OFF (After the fuel pump shuts off) - 55 - 60 psi (This number is to determine the integrity of the system. It should hold that pressure and not bleed down. If the pressure bleeds down it means that there is a leak in the system.)

Key On Engine running it should drop 3 - 10 psi

The pump should pump a volume of about 1 ounce per second.
