Ummm MB doc, think i'll need you to draw me a picture on that. I have no idea of what that is..or where that might be.

If your tower is still sealed from the factory, it will have a ball bearing in the top.

While you're in there, check the idle air hoses previously mentioned in this thread. (see the yellow arrow). These hoses get hard and brittle and stop sealing around the ends. There is another idle air hose coming out the other side of the idle air valve, but you can't see it in this picture. They caused me tons of grief.

Also, you can easily test your idle air valve from here. Pull off the wire (blue arrow) and put a 9v battery to the terminals. You should hear it clunk.

M.B. Doc is an expert (I'm not), so heed his advice!!

1997 S420 - 265k just bought it with a rebuilt trans. Lovely condition

ok for todays update...I did what MB doc (thanks for the pic)said and there was no change in the car. It's still doing the same. It will almost start but won't run. Put a little gas down the air valve and it fires right up then quickly dies. Every now and again can really pump the throttle and it will stumble around for about 3 mins and die. Check fuel pressure and it is the same as before. 80 psi. I also did what tinypanzer suggested (thanks for the pics too). Took 9 volt battery to idle control valve terminals and got no sound, no nothing. Checked the hoses too and they are ok even the one that runs under intake (used a mirror). So whatcha guys think now?

What is the condition of the fuel that's in the gas tank? Fresh or Old???

fresh.. about three days from gas pump to car.. And sorry slk230red didn't say thanks to you for pics

Are you sure the fuel pump circuit is operating properly. You might want to remove the Fuel Pump Relay and put a jumper on pins 7 & 8 to keep the fuel pump running.

Just a thought.

From another 190E owner:

"190E won't start

Found the problem, it was the fuel pump relay. The fuel pump would work when you initially turn the ignition on but when you tried to start the car the fuel pump wouldn't run. Pulled out the relay and bridged pin 87 to pin 15 so the fuel pump is always running when the ignition is on. That resolved the problem so im just waiting on a new fuel pump relay."
