Can someone please help me! I got my ignition coil changed on my 2004 gs300 on saturday because my car was having misfires. After changing the ignition coils I tried to crank the car but it wouldn't start, we disconnected everything new and put all the old ones back on and still nothing, then I realized the alarm indicator is blinking even when the key I in the ignition and turned. I tried a locksmith and he assured me nothing is wrong with the key, PLEASE HELP ME. I've changed the fuel pump, spark plugs and also tried everything I read online about resetting the alarm and nothing works, I can activate and deactivate the alarm from my key pad but the light continues to blink and the car refuses to start
OK all you smarties, here is question that has me baffled - when replacing the fuel pump on these first gen LS400s, there are two options listed
1. The Denso, and
2. The Aisan (guatamala)
Does anyone know what the difference is, and why? I was replacing the FP in my 1992, and not knowing any better, got the Denso from an online supplier based on their claim that it was an exact match replacement for the factory installed FP. When I got the existing FP out, however, the construction was all metal and much more robust, with a couple of shiny bands at the base. I did not see any branding marks on it, but noted that the Denso I replaced it with had the fuel feed nipple made of plastic, and generally appeared to be of cheaper quality (cost about $200) Anyway, I compared prices for both the Denso and Aisan from the Lexus dealership and the prices are very different - $250 for the Denso and $360 for the Aisan (Guatamala)!!!
Can anyone on here shed any light as to why this is so? By the way, I think that I should have got the Aisan for my LS, just based on the pictures from the dealership website show the both side by side, and comparing that to the FP I took out of my tank! $360!!!
Thanks for any insight
p.s. For those who are wondering about the Denso - it appears to be working well, but I am concerned about its longevity, simply because of the apparent cheapness in construction.
Looking for anyone to comment or who has experience with this and would like to make any suggestions.
Approximately, 350 miles from home, the steel fuel line on my 99 LX470
rotted through and let go... The first indication was he stench of
gasoline from the drivers seat... and then the rain of fuel in front of
the rear tire when I stepped out to check.... I dumped 13 gallons in 6
minutes racing to a service station on a Sunday morning at 8:00 am. Any
one with a match or lighter could have sent a wave of flames chasing me
3 miles into town.
Has anyone had experience with this, who has successfully changed their fuel (and return) lines?
I had a "bypass" installed to get me limping home.. but now the truck sits in the driveway waiting for some much due attention.
Does anybody know when to replace the fuel pump resistor on my 1991 LS400 ?
All data I can find, including the numbering on the thing itself says that it has to be 0,73 ohm, and when i measure it with my digital multimeter, the value is 1,9 - 2,0 ohm.
Seems to me that when the secondary fuel pump relay (the yellow one, just above the resistor) switches to it, the fuel pump will be slower than spec.
Should I replace it or just completely bypass it ?
I recently replaced the blower motor in my 1992 LS400 with a after market part, the install was clean with all connectors and fuses reattached. When I went to start the car the blower began to work however, the car would not turn over as if the fuel pump was turned off. I did not disconnect the battery before doing the install. After several attempts of starting the car I disconnected the battery cables for approximately 1hour hoping that it would reset the computer, well that didn't work either. I checked all the fuses and there were none blown. Prior to fixing the blower there were no problems with the car starting at all. There is fuel in the car, and when I turn the ignition I can hear the clicks from the FP relay, but cant get no action........Need Help....Any suggestions?
