Most likely blew a fuse. Check the fuses.
Which relay were you jumping with a paper clip?
That is most likely the circuit with a blown fuse.
Can you hear the fuel pump run for 2 seconds when you first turn the key to run?
Check the "ECM BATT fuse 9" in the I/P fuse block, it feeds the fuel pump and relay, as well as the VCM.
Check the ECM/IGN fuse same fuse block, it feeds the fuel injectors as well as the crank sensor, the ignition coil and distributor.
Was you trying to jump the ac compressor relay?
Ok, that is supposed to be it. Check those other fuses though.
While you are at it, check the a/c comp fuse 14, same fuse block I/P.
A few ways. First, if there are any identical and/or with the same part number, you could try swapping them. You should also be able to put your finger on it and feel if it clicks, when it is first energized or supposedly first energized such as when turning on the switch. You could also jump them like you tried, but I suggest getting yourself a $2 inline fuse and use it whenever making jumps, that way you blow it's fuse hopefully first an use like only a 5 amp fuse when checking something that has a 10 amp fuse in it, like that. Also, you can remove the relay and make sure it is getting voltage to the spots in the relay socket when they are supposed to be hot. Or I suppose you could remove the relay and using a 6 volt battery out of a flood light and an voltmeter place the relay on a bench and work it by jumping voltage and ground and seeing first if it clicks and sends voltage trough when it clicks when you add 6 volts to it. I have never really tried this yet, but just thought of it cause I have been using my 6 volt battery for my flashlight to check the led light bulbs I am installing in my instrument cluster I had out sitting on a bench and it powers them up.
I was more concerned about the correct relay cause all of the location graphics I found so far just mentions that location but doesn't really specify, which one of those relays. I want to check the owners manual, hold on.
The owners manual was no help. Also check the gauges fuse, should be fuse 4.
Ok, make sure you used a fused jumper from now on. I am not really an ac expert, so I am done. YI did though tell you a few ways to test a relay incase you want to jump that ac compressor relay again. use a fused jumper though. I would first check the ac fuse.
Did that answer your question? If so, kindly leave me a positive rating, so I get credit. If you have any more questions, go ahead and ask.
The relay was probably just loose in the socket.
All done now?
Ok, don't forget to rate me well.
I see you continue to view my responses but fail to rate me, is there something I forgot or do you still need help?
