No it is on top of motor.

The above is incorrect , I believe. It appears to be on the side of the engine attached to the water pump. But it is not on the top, as above stated( i just looked, and ruined a perectly good upper hose gasket.)

Without seeing the 1991 Lexus es250, it is impossible to know exactly the cause of the fuel pump problems. A mechanic will be able to look at the car and let you know whether it is a bad pump, relay, or a clog.

How do you change a knock sensor on a 1990 Lexus ES250 it has the same engine as a 1990 Toyota Camry?

You have to take the intake manifold off in order to do this. Both sensors (there are 2 of them) are on top of the heads. A dealer will typically charge $1100-$1500 for this service because it is time intensive. The sensors themselves are around $170 each. I would recommend a top end rebuild to get more value out of the time/money spent on this procedure.

Why would my Lexus es250 be overheating?

It could be a number of different problems. The first thing to do is go to an auto parts store that offers free power-train error code readings, the scanner may answer the question. If not, possible causes are: dirty radiator, bad coolant temperature sensor, bad thermostat, bad waterpump, bad cooling fan or cooling fan relay/fuse. Or it could be a blown head-gasket, which will make your oil light brown and foamy like chocolate milk or make your coolant recovery tank smell like exhaust fumes.

How do you stop the Over Drive Light from flashing at all times in a 91 Lexus ES 250?

dude flashing o/d means problems to your trans check it out No it doesnt. I own a 90 es250 and the o/d flashes when the car is in o/d. There is a small button on the back of the shifter where you can turn it on and off. You might want to look for this button elsewhere if it is not on your shifter.

Where is the fuse box 1991 Lexus?

In the ES250 model, the fuses are located in 2 primary places. In the engine compartment, on the drivers side, along the top outside wall, in a black compartment. Just pop open the snap on hinge to gain access to these fuses. Secondly, inside the car, drivers side floor panel area. Remove panel door to access these fuses.

What would cause the battery to drain overnight on a 1991 Lexus ES250 if the car was off?

Often it's an alternator diode. Check the battery first. When batteries start to go bad they can often start to discharge over a couple hours. Take it to an auto parts retailer and have them test the battery and alternator for you. I had the same problem with my '92 Windom (ES 300). It was a faulty trunk mounted CD changer that was draining the battery.

Does the 2.0 v6 1vz-fe engne fit in the Lexus es has the 2vz-fe 2.5 v6 in it right now but the timing belt broke an i found a great deal on a 1vz-fe engine...?

Yes it does, I have a 1990 Lexus es250 and it had the 2.5 2vzfe and I swapped for a 2.0 1vzfe and it bolts right up swapped all the stuff of the old motor on to the new motor, I did however buy a seal kit timing kit water pump for the 1vzfe motor because some of the seals are only for the 1vzfe and will not work on the other, you get the point. I have 50k on this motor in my car and it works great.
