1993 300se won't start
I have a 93 300se. The engine turns over but won't start. It has become gradually longer to start, now it doesn't at all. Ive changed fuel filter, fuel pressure regulator, distributor cap and rotor. I didn't see a spark when I did an inline spark tester. I smell no gas. It doesn't even sputter when I spray starter fluid in it. New wire harness 1 year old. Any ideas ?

The battery is bad. I have to jump it to get it to get the engine to crank but it doesn't hold a charge for long. I also used a good battery testing it and the same result.
Not sure on the condition of the plugs. The car ran very smooth when it did start so I didn't think that was the issue. My concern is that i don't even smell gas. Would the crank position sensor be responsible for both no spark and no gas ?

You should heat the fuel pump(s) running when they key is turned on, they are controlled by a relay, but will only run to pressurize the system if it does not start. I would also think CPS, with ether or gas and spark it should o something

GUESS WHAT...SHE STARTED !!!!
Well after 6 months of guesswork and buying parts I don't need my problem is SOLVED. All i needed was a new IGNITION COIL !
Went to see Sam at Advanced Auto Sports in Farmington Hills, MI. He was highly recommended by others and figured this thing out in no time. It's good to find a fair mechanic thats really looks out. Can't say enough about how much I appreciated that and getting back on the road. Time to get her all cleaned up. I'm back in the game. YEAH !!!!
Thanks for all your advise too. I helped to understand the cause and effect of it all. Much appreciated. GO TEAM !!!
