Question about 1996 Lexus ES 300

1 Answer

I have a 1996 lexus es 300. code P0303. I have 125# of compression in it. I did the screwdriver to the ear test with th injectors and #3 in the back is not clicking very loud like all the others. Come to think.. the plug didn't smell like gas. What should the compressions be in lbs's?

Most likely the crash sensor (located somewhere in the front of the vehicle) has triggered. Some can be re-set, most have to be replaced, otherwise the vehicle will not start.

Tech ( but it's not hard ) use a Q-tip and some 91% Isopropyl Alcohol.
This will help for new cd's.( before even new ones errored out)But old ones, it still error's out.
Because the laser is old and weak.But if you got the time it can't hurt.

SOURCE: alternater

Once the battery was placed backwards it may have sent a charge to the radio causing it to stop working, the alternater you should just try to either get it directly replaced same model..but if you want to try make sure all conectors are the same...other then that you can probly get a rebuilt one cheaper...rebuilt your current one will make sure its the same...and one major thing before you change anything make sure that the belt is on properly for the alternator and everything and just check if you are geting any charge from it

google the codes you have posted here
codes P0303 and P0302 lexus 300
these are cylinder misfire codes. There is a procedure for this but I would suggest you rad that and follow directions before going the compression test route. The other thing you said was that all this started when you ran out of fuel. Could be you burned out the fuel pump or the pump sucked the junk up off the bottom of the tank and is now plugged up. So many choices but if it was me, I would start with the fuel pump before I started tearing into the motor.

Hope this helps.

I just replaced the head gaskets on my 2002 Lexus es300. And it won't start back up. It's getting fuel and it has spark

Well, an engine needs 3 things to run....fuel, spark, and compression. But they also have to happen in the right time in the right amounts. If you are sure that you have fuel getting into the engine, and you are sure that you have spark at the plugs. I think I would be checking the timing and the compression. And remember, just because you have fuel pressure at the fuel rail doesn't nesissarily mean that the injectors are opening.
