SOURCE: fuel pump relay

Hi,

For a 1998 Audi A4, the Fuel Pump Relay would be J17, the 6th (last from left to right) on relay bank marked "Central Electric Panel". It would have markings "87F/DTI".

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: 2007 Jeep Wrangler Unlimited Crank-No Start. Replaced FP.

Hey Tim take a look at this, will this help ?
SUBJECT:
No Engine Crank Or No Engine Start Due To Electronic Lockup Of The WCM / SKREEM
OVERVIEW:
This bulletin involves the replacement of the Wireless Control Module (WCM), and if
equipped, the replacement of the Electric Steering Column Lock (ELV). The WCM is also
referred to as the Sentry Key Remote Entry Module (SKREEM).
MODELS:
2007
SYMPTOM/CONDITION:
The customer will experience a no engine crank AND a no engine start condition. Also, the
remote keyless entry (RKE) system will not operate. This condition may be due to an
electrostatic discharge (ESD) from the ignition key into the Wireless Control Module
(WCM), causing the WCM to electronically lockup. This condition may occur more
frequently in dry and/or cold weather conditions where a sufficient electrostatic charge is
more easily produced. This condition is corrected by the replacement of the WCM
DIAGNOSIS:
1. With the condition present (i.e. the vehicle in the no crank / no start condition), connect
the StarSCAN® scan tool to the vehicle.
2. Turn the ignition switch to the “ON” position, and power up the StarSCAN®.
3. If the WCM is electronically locked up, the StarSCAN® will display the WCM as being
“off bus”.
4. If the no crank / no start condition is present, and the WCM is “off bus”, then reset the
WCM by temporarily removing the IOD fuse (with the key out of the ignition switch),
wait for 10 seconds and then reinstall the IOD fuse.
5. With the IOD fuse reset having been performed, verify that the vehicle will now crank,
start, and run.
6. If the condition is temporarily corrected by performing the above steps, and if the part
number of the WCM is earlier than the part number of the WCM listed in the part
reference table in the Service Bulletin Parts Required Section below, then perform the
Repair Procedure.

Fuel pump relay switch for a 96 Mercedes-Benz E 320


I believe it is integrated in the K40 relay module in the front right engine compartment next to the ME control unit. I also believe the 97 W210 relay was moved outside of it. That fuel pump should be outside of the tank so it will be easy to test for power and ground at the pump if you are having a fuel related issue. I have replaced many more fuel pumps on these vehicles than relays. I usually replace the relay as a precautionary measure, but not because it failed. I hope this helps you.

Can't find the fuel pump relay on my 1990 190E Mercedes. Every thing I see says it is in the engine compartment behind the battery. Not so on my 190E. Where else could the fuel pump relay be?


Relay should be behind fuses under a screwed down cover. My question to you is why would you think the relay is bad? Check voltage at the pump as someone turns the car to on. At this age it's most likely a dead or dying pump. Other things to consider are OVP relay (behind the battery) , coil dead, general tune up ie plugs, wires, cap and rotor.

1992 mercedes 300e cranks over starts for a second then die


Could be a number of things. Start with the fuel pump relay. When your key is in the start/crank pos. it overides the relay as soon as you release the key to run possition the relay has to stay ingaged or the fuel pump will shut off. Also look in your owners manuel for impact or emergency fuel shut off switch reset.

My 2005 dodge magnum sxt AWD is having starting problems. It has happened twice so far. I start the car and then it dies. start again and it dies again. try again and it won't even start. I've checked...


I'll be honest, it sounds like the transmitter in the key isnt reading. A key remake without the factory transmitter will start the car, but only keep it running for a few seconds before cutting power to the motor. your electronics will still run....This may be too obvious, but honestly, thats what it sounds like.
