Car went into limo mode, reduced power came about, cannot drive more than 10mph, and car has shut off in that state . The ignition coils are getting no power whether I switch them around between cylinders . 1 2 and 3 just appear to be dead all at once . The car runs super rough at idle . I changed the spark plugs , 02 sensor, and no love also. What reason why three of these cylinders will stop all at once? Can the HPFP do this or possibly DME gone bad ? Here's my faults


Szl can signal/ detection tank empty/ communication (sportsmode egs) is missing/ message error/ injection calibration


Ignition cylinder 1 burn time too short/ building up of fuel pressure ekpforward stroke

It wouldn't be a bad idea to switch your fuel injectors around and see if they are the problem. If they are then installing new ones is easy...

[DJtoad]

The first thing I'd check are the brown ground wires on coil harness. They terminate on top of two of the valve cover bolts and can break off pretty easily, especially during a valve cover gasket replacement. Very easy to check and simple to fix.

Sounds like the MOSFETs blew

[Dreezyjuice08]

Thanks guys ! I'm gonna try all of these today starting with the injectors . Off to buy another multimeter, saving the mosfets for last:/

[Dreezyjuice08]

So the mosfets are good! Fuel pumps turns on and car turns over roughly! Can someone explain to me how to test the ground wires on the coil ?? Set it to DC, with car power on , put the negative on the bolt on the ground and the positive where?

[DJtoad]

Just make sure they are attached to the lugs and none of the wires or lugs are broken. All of the wires in the harness are small and aren't that hard to damage.

power supply on the DME went bad and was unfixable. Had the DME replaced and car ran better. I also had leaking injectors, which fixed this while issue.

How does this happen?

We had a similar issue with our MDS80 DME. Ended up having to get a new DME. Went with a MDS81 and the car now runs great.
