1995 Lexus ES300 car wont start, tried alot of stuff, changed battery, checked fuel pump, fuel filter have not replaced either yet, noise from pump suggests its working, Spark is fine, distributor cap replaced, car turns over but wont ignite.

When the engine stalls;
Test for spark (ignition)
Test for fuel pressure & check fuel pump volume

Most cars have a rev limiter built in and will not let the engine goe past 4000 rpm's you may want to change out the spark plugs as often if it has flooded just once the plugs do foul out

Sounds like you have a serious vacuum leak. Don't bother checking the fuel pump in tank, it's working, otherwise it wouldn't start and idle. Vacuum loss will cause it to die because when you open the throttle even a little, it gets too much air and not enough fuel at the same time. Check that all vacuum lines are connected and not off or badly cracked.

you should never need to change the fuel filter. i would only change it if you have a fuel pump go out. it is under the rear seat just for your information.

Try to replace the fuel filter and then check the spark plugs. Mke sure to clean the spark plugs and after you clean the spark plugs and still the same it wont start replace the spark plugs and check the distributor as well.

to tune it properly change the following
1.Air filter
2.Spark plugs
3.Fuel filter
4.Oil filter and Oil to make sure the engine is clean inside
5.Run at least in the fuel tank injector cleaner
6.Check the timing belt age as it would need to be changed if it hasnt or if you cant tell when it has
7.If the car runs well that will do if its running poorly you willneed to llok further .like getting it pluggrd in to a diagnotic computer to see if theres anything wrong

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.

I would have started a little cheaper myself. First, is it a fuel delivery problem or an electrical delivery problem? It could be something like a bad spark plug or wire, a clogged fuel filter. You indicate that you have already spent alot of money...some on a fuel pump and some on an ignition switch and crankshaft sensor. These are all expensive items that may not even be the problem. Check out the cheap stuff first and work by process of elimination. Hope this helps. Good luck.

replace timing belt on es300 1995

I had a similar experience just the other day, i stopped to get gas and turned the car off and when attempting to turn the car back on nothing would happen. Well, let me rephrase the lights inside and out would work as well as the ac and the radio. My initial train of thought was maybe it was the battery so i went and purchased a new battery which was around $100, I installed the new battery and the car still wouldn't start. Does your car make a clicking noise when you turn the inginition key or is it just silent? If it is silent, you might want to check to see if your starter has burned out. Luckly a friend of a friend does his own mechanical work and was able to remove and replace the starter for me. After the starter was replaced the car started right up and ran perfectly. Not sure where u live but in my area a starter ranges in price from $100-200, but they also charge a core fee ranging from $45+, which can be reimbursed if you bring in your old starter to the store. I would suggest getting a starter with a lifetime warranty as well, but thats just a suggestion.

Hope this helps,
