I have a 2000 s430 that i drove yesterday for about a mile when it began jerking and died. I was able to get it running for a while to pull it over, it ran teribble. It died again and wouldnt start , the engine turns over but wont start. I removed the air intake pop of covers and sprayed some starting fluid into the air intake at the back of the engine. The car started and ran for a few seconds then died again, I sprayed it a few more times and it started each time but will not remain running. I had a friend of mine remove the injectors to see if fuel is coming out of them while cranking the engine , and yes it does . We do not have a pressure gauge to check it properly. I believe that the problem is the fuel pump, do you agree or do you have a few other suggestions
