I HAVE AN 1993 MB, 2.3, 190E. 5 SP.
HAVING A FUEL PROBLEM, I THINK.
CAR IS EAGER TO START, BUT WON'T IDLE/RUN.
HOW TO TEST IF FUEL PUMP RELAY IS WORKING PROPERLY?
HAVE REPLACED THE: PLUG. WIRES. CAP/ROTOR. FUEL
FILTER. SEVERAL BREATHER HOSES NEAR/UNDER THE AIR
FILTER HOUSING. FUEL DIST. FUEL PUMPS (2). NEW CAT.
NEW MUFFLERS (2). AIR DUCT HOUSING.
LABOR HERE IN THE SF, BAY AREA IS $130/HR. BIG BUCKS
FOR A TINY BUDGET. WHAT'S LEFT TO CHECK ?
I HATE 'REPAIRS-BY-ERRORS............'

TKS IN ADVANCE.

Do a search on fuel pump relay, you can hot wire it to make the fuel pump run for testing.
I do not know the pins off the top of my head.

Did the fuel pump relay trick work?

ALLO.

SEEMS TO PUMP ENUF GAS.
PREVIOUS OWNER SAID HE REPLACED BOTH PUMPS
WITH 1 YEAR OF MY BUYING CAR. WHAT'S NEXT ?

I AM THINKING OF STOPPING, THE" REPAIRS-BY-ERRORS"
APPROACH AND DONATING THE CAR TO A CHARITY, TAKE
THE $4000 LOSS, CRYING A BIT, AND FLUSH IT AWAY...

I'M ALSO A BIT ANNOYED AT THE SELLER, WHO PROMISED
'THIS CAR WILL NEED LITTLE REPAIR TO MAKE IT A SPLENDID
MB.

Conrad: The most expensive and frustrating method of fixing a problem is to throw parts at it.
To save money and your nerves, get a good professional diagnostic from a competent MB shop.
Fuel pressure, fuel volume, fuel flow, fuel injectors flow and spray pattern, ignition timing, ignition voltage, testing of all sensors, vaccum leaks, etc.
It may cost you a few $$. It looks like so far, your have spent quite a few $$ and you still have the same problem.

THANK YOU FOR ADVICE. ANOTHER PART OF THE ISSUE
IS THE SMOG/EMISSION ONE. THE CAR MUST PASS THE
STATE TEST, OR NO REGISTRATION IS PERMITTED & THE
CAR CANNOT BE DRIVEN. SOMEWHERE, SOON IS A MOMENT
OF DECISION.

WHAT I NEED, I THINK, IS A CLEAR DIAGNOSIS.
ARMED WITH THAT, I CAN ESTIMATE THE COSTS.
THEN, DECIDE WHETHER TO KEEP OR TOSS....

"REPAIRS-BY-ERRORS" IS ALIVE AND WELL IN TOO
MANY SHOPS........

PS. I AM NOT A MECH/TECH. I HAVE PAID FOR
THESE 'ON-GOING-' ERRORS/REPAIRS. SO, I'M
NOT THROWING PARTS, BUT BUCKS, NON-STOP
BUCKS FOR SOME TECH/SHOP TO SPEND ON THEIR
HAWAIIN VACATION.

HUMBUG ! !

COME NOW PROF. you own 4 MB's, 2BMW's, an MG TD and you still let shops replace everything in sight without it being fixed. Likely all you needed in the first place was a fuel pump relay.I got a dandy 74 240D that I'll let you have for 25K needs a little work!

The "old 190e" had the exact same problem. Per the advice of a local tech friend, I bled the injector lines AT the fuel distributor.

I had never hear of doing such a thing. He was right. A ton of awful goop came out and all of suddent the car idled well and ran great.

May want to give it a try.

MANY TANKS, HAASMAN.

I'LL MENTION IT TO MY MECH. ALL OF 'EM....

SOMEWHERE, I DID WRITE THAT I USE LARGE PRINT TO
SEE. NOT TO BE RUDE. EVEN MENTIONED IT TO THE
WEB-MASTER.

KEEP UP THE ADVICE, IT'S GOOD STUFF.....
