1990 300E FUEL PUMP QUESTION

[JOSE RAMIREZ ESTRADA]

Hello again,

My 1990 300e w124 3.0 doesn't start, I checked the fuel pumps and the second one does not work.

I looked for fuel pumps at pelican parts and there are many options, but a great question arises, "are the first and second pump the same?", there is no indication of the pumps been different.

Any advice will be greatly appreciated.

Thanks

The first and second pumps are the same.
What is your mileage? I changed both pumps on my 89 recently at 340K Km. I opened them up and the commutator had a lot of wear. Definitely time for new ones (I bought the Bosch).

It's around 150K miles (240k kms), i will change the one that doesn't work, if the car starts, then will start saving money for the other.

The w124 is a wonderful car, but it's very complicated.

thanks

Won't the car run with just one pump but cough under load due to inadequate fuel delivery. I guess I always assumed that was why they put in 2 fuel pumps. I do not know this so it is a question rather than a statement.
