-4 Gallons ...? Sounds like too much. You mean 4 Qtr..?

But any way. Don't expect the same amount that you pour in. because due to trap some in the filter, possibly the engine already
burn some and may be some leak.


Good Luck

It sounds like it could be a fuse isuue. I would first try to see if you can locate a fuse for the horn in your fuse box, ( fuse box should be inside, on the driver's side, under the dash, near the driver's door. When you remove the box cover, look on the inside of the cover, it may have fuse diagram to help you locate the fuse for the horn.

If it isn't a fuse related problem, you may need to run a new lead wire to the horn. The old wire could have be faulty from breakage, or corrosion.
That was good thinking using a jumper wire.
Best of luck!

Could be.
If the trans is stuck in park, you should be able to turn the front wheels if both are off the ground. Otherwise, if the brakes are not stuck on, and you can't turn either wheel with both off the ground, its the trans.

You cant check fuel pressure that way. You have to connect a fuel pressure guage to the fuel rail at the schrader valve. It should have 30-40psi when ignition is turned on. Injectors not functioning properly will cause a misfire Sounds like a fuel pump or fuel going out.

that happened to me and I solved the problem by replacing the computer. It cost me $40.00 out of a junk yard and it has been running perfect ever since.

This car uses R12, it is no longer available, you must convert it to R134, this requires the compressor and reciever dryer be replaced and the system flushed out and the new PAG R134 refrigerant oil be added and new charging port kits installed. Is that car worth this effort?

Sounds like the voltage regulator in the alternator is bad. Take the alternator off and have it tested (for free) at a parts store.

GM are usually in the trunk on same side as fuel fill door. Look for small hole on the sheet metal ribs on side of trunk.
