Can here a relay buzzing when key is out of the ignition switch. Located noise under hood in fuse box . Pulled a 4 pin micro relay out and the buzzing stops. Engine will turn over but not start without this relay. Maybe the fuel pump relay. Swapped the relay with another identical one and still get the buzzing from this same place. Van starts and runs great but this buzzing I think is the beginning of more serious problems.

The horn relay was shorting out but not activating the horn. When you swapped it out it sounds like the fuel pump was running all night killing the battery. It sounds like the relay had a dead short inside and melted itself to the fuse box. Depending on the extent of the damage you might have to replace the fuse box as well as the relays.

try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.

If it is a single click, the problem lies in the starter solenoid or relay. If it is several clicks in succession, the battery may be low or there may be a loose cable.

also try this :-- Please make sure the battery is fully charged before doing this test! Also make sure all the connections on the starter, battery and cable ends are tight and clean! this is important!! This won't be fun to test but it will tell you if the starter is good or not. Crawl under the car. (Make sure you use the proper jacks and jack stands!) find the end of the starter (not the end that is attached to the bell housing) and find the solenoid switch. it should have 3 bolts on it. Two large ones and a small one. The top large wire should be the positive battery cable, the bottom large wire should go into the starter and the small wire should be from the ignition switch. Take a wire and hold it to the top large wire on the solenoid. (be careful of the other end of that wire when you have it connected to the top large wire of the solenoid! don't ground this wire. it will turn out badly. take the other end of the wire and touch it to the small bolt on the solenoid end. If the starter is working, the solenoid should engage and the starter will turn. If this happens it is most likely the ignition switch. If the starter doesn't turn, the starter could be bad.

Starter Relay Test
Place transmission in Park.
Apply parking brake.
Check for battery voltage between starter relay battery terminal and ground.
Connect jumper wire on starter relay between battery and ignition terminals.
If engine does not crank, connect a second jumper wire to starter relay between ground terminal and good ground and repeat test.
If engine cranks in step 3, transmission linkage is misadjusted or neutral safety switch is defective.
If engine does not crank in step 3, starter relay is defective.
Follow this step by step and you will pinpoint the problem.

if it was me i would make sure its not the fuel pump relay give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair Manual for your SUV wish you the best of luck Michigan Man.

make sure you have spark, sometimes if you start bypassing stuff the ignition works only on a resistor to much electricity and it won't work, not enough and it won't work.
