There is a major leak in my 92 es300 lexus where would be the best place to start looking

I have a 2005 ES330!

The dealership does all my repairs, but I found this.

This is how I reset the security system each time after disconnecting the battery:

1. Insert master key (non-remote master) into driver's side door.
2. Remove key.
3. Insert master remote key into driver's side door.
4. Remove key.
5. Insert master key (non-remote master) into ignition.
6. Remove key.
7. Insert master remote key into ignition.
8. Remove key.

The is additional information in the link. If that doesn't work, the best place to ask would be the Club Lexus forum.

No it will not cause a no spark condition.

The motor is bad.Time for a new car.

CHEAP BUY FOR THE BODY$500.00.GOING COST $2000.00 FIX ENGINE.IF YOU HAVE LOW COMPRESSION. ENGINE WORN OUT.

IM SUGGEST YOU TO CHANGE THE CAR, THE PROBLEMS BEGINING SOON

The 92-96 ES models are very similar in most components. The body style changed in 97.

My first guess would be "No."

there are fuse blocks under the hood, under the driver side of the dash and under the passenger side also. the ones under the dash may be located behind the kick panels.

LOOK UNDER THE HOOD. AND CHECK FUEL LINES FOR LEAKS. YOU PROBABLY HIT AGAINST FUEL LINES WHILE REPLACING THE WATER PUMP.YOU NEED TO FIX FAST.FUEL LEAKS IS DANGEROUS.

Your car has front disc brakes, the disc's are running out of true, as u apply the brake this causes the steering wheel to shake, the higher the speed the more u feel this, the solution is to have the front brake disc's machined true again on a brake lathe or if they are to thin replace them.

drl relay is under the hood.
