Hi,
In the morning when I start the car in turns over right away and runs excellent. However once the car is warm and I try to start it, I have to push down on the gas pedal at least 1/2 way down to get it to start, and then sometimes it stalls, but it has never failed to start. One fuel pump is noisy and I had the fuel filter replaced. A tech checked the fuel pump relay (behind the battery it says kickdown on it.) and said it was ok. At one point I saw the ABS light flash on. (just one time so far.) Is ther a relay for cold/warm start or one associated with ABS any ideas or help would be great.

Have you check the spark plugs' conditions?
I understand for the ABS light, with some of the w124 when driving with the wheel straight for a while, the ABS light comes on for no reason.

I would also check the OVP.

Hi,
Yes plugs are first thing I replaced, how do you check the OVP it is the one with the fuse on top of it right?

Problem solved with one bottle of Techron plus an hour drive on the highway!

Are you sure the ABS light does not come on anymore? Seems like a different problem all together.
