spraying starter fluid before the air filter sounds like a great way to have a flaming air filter on your hands...

do it properly, pull the intake tube and air filter out, spray into the opening before the AFM. Still not guaranteed to not muck up the AFM, as karman vortex AFMs are very sensitive to solvent contamination.

Thanks!!! I'll try that. I have the cover off already but the air filter is in the way. Should I take the air filter out? Once I do this and it starts, what does that mean?

the air filter in the way doesn't matter - ether is quickly a gas, once you spray it

okay thanks. again what does mean if it does start with the fluid?

this statement seems ridiculous


this sounds more plausible, but if the car won't even crank, I'd much rather have to replace AFM than a starter!

Because you took the time to point it out TWICE I'll elaborate.
Ether is stored as a liquid in its container, pressurized by some type of propellent (in aerosol cans in this case). It instantly boils into a gas upon release due to the difference in pressure from inside the can and the atmosphere. Equally important, it is a gas only when the vapor pressure in the surrounding environment is below a certain threshold. If the vapor pressure in an enclosed space (say, an air-intake chamber, next to a filter element, which is the low-point of the system) is increased by oversaturation with ether, the phase change from liquid to gas does not occur quickly enough to keep the newly added ether from puddling/soaking the airbox+filter. This condition is actually quite common when trying to start an engine, moreso than when spraying ether into an already running/turning over engine as there is some vacuum decreasing the partial pressure of Ether. The main fire hazard then is the (relatively high) likelyhood of a simple backfire in the intake, which normally would not be an issue, igniting the volatile mix of air and fuel in the entire intake tube. And, you know, sparks of any type.


I would rather replace neither if they weren't broken.

Ok got my problem fixed!!!

It was the fuel pressure regulator. After replacing all kind of parts it was a simple fix (money spent ). thanks everyone for your help. This forum is the best for the fixer upper on our own cars.

Backfire is possible but extraordinarily rare on fuel injected engines, that was a common problem back in the days of carburetor aspirated engines, but a super rarity today - and no one is advocating an oversaturation condition, just a 1 second spray in the intake area that I marked in green - Neither the plastics used in the LS400 intake area, nor the '95 or newer MAF sensors are bothered by ether, my 96 has been sprayed more times than I can count when my ECU capacitors went out, with no ill effects to any plastic or sensor.
