Ummm, Yeah I checked the other fuses and they are fine. I can't check #18 125A because I can't find it. Do I have to take the box apart or something to get to it? Thanks again so much for any help.
Thanks,
Nancy

Hey, I checked the #17 fuse and it is fine as well. Do you think it could have something to do with the battery? There appears to be some sort of corrosive leakage out of the bottom of the battery in the corner because it is all over the battery tray.

Yeah sounds like the battery has blown out. Replace the battery.

Unable to start Vehicle.

1. Turn ignition - all lights and radio are strong. Battery is fully charged. Trying jumping off also. I cnah ear the fuel pump kick in. But nothing else

. Vehicle is not even trying to crank. The vehicle was working perfectly fine - we got home after a short drive back from the store. And about 2 minutes later - we were attempting tostyart the vehicle to move it to the front of the driveway and that's when it would not start. We charged the battery and we also tested the terminals and cable s- and pwer is making out to the pos/neg cables. No corrosion on battery at all. (Note: had the catalytic converter and fuel pump repalced back in Jan 2010 - that was a nice post Christmas present

of 1944 doll hairs). Ialso changed out the starter in mid January of this year.

2. After I turn the key - the security light comes on -- and stays blinking until I take key out of ignition. Some history on the ignition - we had to get new keys and they were not cut the best (I guess) but there is always some difficulty in getting the key to turn. Have to jiggle the key and it always started (after a few times of attempting to turn to the key). Not sure if this has affected the ignition or the security of the vehicle.

3. I have heard conflcicting stories of whether or not it is the security system. I guess 'maybe' each vehicle maker may be different on how the security system stops a vehicle from starting.

-A Mechnaic tld me that if I hear the fuel pump it is not the security system - that the security system will disable the fuel pump? Pretty sure the fuel pukmp diud kick in whne I tried to start.

-A friend told me that the vehicle would attempt to start - it would turn over but not start if it was the security system.

4. Checked the fuse (I guess the big square 4 prong deal in the fuse box) is the starter relay? Relay/fuse is good.

5. I am going to take out the starter today and have iot tested at Auto Zone where I bought it. I guess I can do that.

PLEASE HELP.

Your saying, no starter cranking action? Check the starter circuit. You can start with the circuits at the starter relay. Voltage for the load side of relay should be hot all the time, terminal 30. Voltage to the coil side of relay, terminal 85, goes hot with the key in the crank position. Is wired through a crank fuse and neutral switch. Passlock theft system should be injector disable, shouldn't have any effect on the starter motor circuit.
