If nothing at all comes on,your ground wire could be very corroded or disconnected from the frame connection.First examine the connection on the battery.A little corrosion in the right spot will cause no power.If that isn't it,trace the negative cable as far back as possible.If you can,check the whole length of the wire to the frame.It should not be very far back.If this is not the problem,please reply back and i will get an autolink to your post and will replay ASAP.Good luck!

    You betcha.I have a couple of errand s but will check back ASAP.Greg

    There is a fuse box under the hood which is called a power distribution box.It is easily accessible on top of the engine,off to either side.They may or may not be labeled.Check some of the higher amp rated ones.They should be in line with the battery system.If you have trouble determining if a fuse is good let me know.I only have free long distance after 9PM EST,but if you have a home phone with free,perhaps you could call me.It is kind of hard to describe and we would end up emailing back and forth forever but a phone call would be very easy to check results and go to the next step.

    There is a fuse box within the car and one under the hood.The one under the hood simply looks like a black plastic useless box and is common to most cars,however,it is for the very high power systems which break down into the lower fusebox within the car.If you're not sure what you're looking for,you may not even notice it.Your best bet to find it is to call a GMC Jimmy dealer and the will give you a better description and location better than I because different makers have different ways of doing things but is normally near the very top,probably near the battery and the top snaps off,but be a little careful as to not break the snaps.They should not but plastic will be plastic.Good luck!

    Sorry but diagrams of this sort are not free downloads due to patent rules.Also,models from this year should no longer have distributors but should have an ignition pack/coil which makes it unnecessary to line up the connectors like in the old days.If you have an email,I could send you a picture of what mine looks like so you have a general idea of what to look at.It looks like a part which appears to really have no function and is hard to describe but contains larger than normal fuses.Greg

If the fuseable link needs replaced where is it located

Fusible links connect to battery power, usually somewhere along the red (positive) battery cable. On some vehicles the links connect to the red cable at the starter post connection, lots of GM cars put the links there. Older Fords had the links connect to the battery cable at the starter relay on the passenger fender. The links have to connect to direct positive battery power somewhere, because they work independent of the key switch being on or off. They get power from the battery and not from the ignition switch. Think of your headlights: you can use them with or without the key. That is because the fusible link (if so equipped) for the headlights gets power right off the battery.

No juice

Have you checked the connections with a meter ? Its possible a battery cable has corroded inside and is not making connection even tho it looks ok from the outside. Could be a ground connection too.
A volt meter would tell you how far the power is getting from the battery before it stops.

Ignition system is not getting any power. I replaced my battery and still no power. The key doesn't even trigger the door ajar tone. I checked all fuses and connections. Could it be a sensor or a part

Make sure your battery is fully charged.You have some power so your battery or connections may be bad.You may have a fried fusible link.I cant tell you where it is located though.Check your cable connections at the starter and the ground at the end opposite the battery.

92 GMC sierra pickup with a new battery, has no power, checked battery connections, even with jumper cables it still has no power

I would start with the fuseable links on the starter and the ground connections for the engine. One of the battery cables could be corroded inside under the plastic.

Drain on Battery; Alternator and Battery both cheched and are "OK", All power shuts down intermitantly with no consistant pattern or symptoms.

That sounds like a loose connection of the main power cable from battery to system. Check where it is connected (ob battery or starter) fo looseness. If OK check connection on main fuse box.

I own a 91 Mercury ( ford) Capri convertible. I went to start it and it turned for a second then died. All power to the car died instantly. There is no lights no radio no lighter no instrument light no...

Has to be a cable connection issue of some sort. Check the other end of the battery cables, either the ground connection to the chassis, or power connection to the under hood fuse box. Could be that one of the battery cables has broken inside the insulation yet the connector looks good. Try using a cheap ohm-meter to see if there is a break in either cable ...keep looking!

I have a toyota corolla and battery is fully charged no power

Sounds like a bad connection with one of the battery cables check the connection to both cables at both ends and I personally would make sure that i cleaned the main engine ground (where the negative wire from battery connects to engine). Good luck!

Honda civic hatchback si it has power till turns the key

It sounds like you have a loose connection at the battery, the door chime and ecm lights don't require much power. As soon as you turn on the key, more power is required, with a bad connection the power from the battery, will drop off. My guess either bad connection at the battery or a battery with a dead cell. Hope this helps.
