that is the power module.
can someone tell me what this is called?
i have had a problem with the car just cuting off at random times for the past few months but now its doing it so bad it is undriveable.where the arrows are at is where its making a clicking sound and if i unplug the wire harness from the air box the car doesnt run at all.if i turn the key on after about 15 seconds it sounds like wires burning(even tho no smell or burnt wires) then it starts to click,i can put my finger on it and feel it clicking on both spots.was hoping i could get some info on what that has to do with the car just cuting off.thanks in advance

what about the other one(the arrow to the left) what does that have to do with the power Module?
I think that is the A/C relay. I forget which is which but there are 4 (I think) there, starter, ASD, cooling fan & A/C. The starter relay wouldn't have anything to do with the car shutting down, and neither would the cooling fan relay I think. If it's the ASD and it's not staying closed, then when it opens you loose the fuel and ignition. If it's the A/C relay the only way I think it could shut the engine down is if the compressor is seized. Check to see if you can turn the compressor by hand. I think the ASD is controlled by the LM, so it could be the LM faulting causing the ASD to open.
the ac pump is off the car at the moment so it must be the ASD relay or the Power Module making it cut off,the clicking starts at the power module first then the other relay startsI think that is the A/C relay.

the power module controls the ground for the relays and such, if that stuff is clicking with the power module, you may very well have wiring issues or plainly a bad power module. what are we working on? year,make,model,engine please

The ASD relay can sometimes get worn out try another one, Also I had this type of problem with my 85 GLH-Turbo.It stumped me for 2 weeks before I figured it out. It was the wiring harness directly behind the battery,Acid ate the plastic coating off the wires, Inside the plastic ribbed covering, which was containing the wires that directly goes to the power module look at that too just to be sure.
ASD is integral to the PM on 85-87.
Are any fault codes set?

I thought that was '87 only....?ASD is integral to the PM on 85-87.
So that leaves only starter, cooling fan and A/C - can't be the starter or other bad things would be happening, A/C is removed, so can't see that causing a problem, which leaves cooling fan. I don't see how that would cause a shutdown either. Perplexing.
no codes have been setASD is integral to the PM on 85-87.

84 it is located behind the R/S kick panel with the LM, 85-87 integral to the PM, 88-90 underhood on the L/Fender, 91-...depending on model on L/Fender or in the PDC.
I am on my way out now so I will have to look over the wiring later.

Also remember, the ASD relay along with almost every other integral piece to keep the motor running rely on the HEP working correctly. If the HEP is going bad, it will intermittently make the car cut out, shut the ASD off, etc.
Like others have said, inspect wiring near the PM first, even disconnect the PM electrical connectors to ensure the terminals/sockets are not corroded. 20+ years of life on the road doesn't do any favors for electrical components.

i thought it might be the HEP also when the car first started doing it but after 4 diffrent HEPs and checking the HEP wires all the way back,its not the HEP and i can hear a funny sound coming from the Power Module even with the car off/switch on and all the wires look and feel good(doesn't crack when bent)looks like im going to have to find a Power Module from somewhere.Also remember, the ASD relay along with almost every other integral piece to keep the motor running rely on the HEP working correctly.

Your PM connectors look dirty, and could also be loose.
Try cleaning the plugs both on the harness and PM very very well, then re-apply some dielectric grease to all the plugs.
Also check that the ground straps (braided steel straps around the engine) and that the ground from the battery are properly connected. When the ground connection is lost (especially near the fuel rail) you'll get a clattering of relays and the PM, and power will be lost.
I had this issue when the ground strap at the intake manifold and on the firewall came loose, or were otherwise not making good contact. Also had the issue when the ground wire to the PM came loose in it's plug. Ensure that all your plugs and grounds are good to go, and I bet the problem will vanish.

everything on the car is grounded great.ive replaced all the grounds and even added some extra just for good measure.im thinking its got to be the PM now,that is the only thing i haven't replaced yet.now the search starts for a new one:bang headYour PM connectors look dirty, and could also be loose.

As already stated connector/terminal issues are a common problem with 20+ year old wiring.
Verify all the connectors/terminals are clean of tarnish/corrosion,terminals are not spread/pushed out and are locked into the connector.
Since you have multiple relays clicking on/off you have to determine if you are losing a power source or ground.
Since a shorted relay/circuit can cause this problem start by disconnecting the external relays and see if the problem stops.
If it does plug them back in one at a time to determine which relay/circuit is causing the issue.
If the problem persists with all of the relays disconnected you will need to check all of your power sources and grounds into the PM.
