Jeep Grand Cherokee 2.7 CRD not revving or accelerating

[Harlekin]

I have now replaced all affected sensors. previously I had already replaced the entire engine wiring harness.
Now I've built a new and can be programmed, but it has changed nothing.
the car is resting on.
I have no more idea what to do now.

Ohh gutted for you sounds like u have tried everything
Is there not a breakers yard u could get the main ecu and the gearbox ecu and digital clocks
So u don't have to programme anything
I have herd the gearbox ecu causes problems

Being a jeep it's probably the fuse to your heated seat makeing the cake not work
Ha ha

Have u checked fuel rail pressure and so on

[Harlekin]

i find it very strange that nobody have the same problem like i.

it cant be normal.


is it possible that the wiring harness from the engineroom to the passengerroom is broken and that the problems come from there???

yea it is strange there was 1 other guy with similar issuses but his was resolved with a ecu and haveing jeep recode it to match his car with the situation u are in its hard to say all wireing worth a check tho

Did you ever get the TCM tested

[Harlekin]

where have you read that the other guys have only change the ecu and then whas all ok?
i have only read that he have change the ecu and then nothing.
i have wirte him a mail but he dont answer.

tcm= transmission control modul??? the ecu from the automatic gearbox???
no, that i have dont check, because i have no drb and i cant check it.
but the tcm have no troublecodes.

some guys say that the ecu isnt crashed. the ecu is ok, but the trouble codes cant reset because the failure is still there.

New battery .. ?
Get to an auto electrician and get them to check the alternator and battery .. once the battery is replaced (if required, however once these guys are flat they are not really good again) and you will probably find all goes away (after the errors are reset of course (the auto electrician will have a scanner to do this).
