73 maf voltage

31 no rpm signal
was expecting crank sensor but no ! just cut out coming up to a roundabout and would not go again any ideas on the 72 code :(

72 Amplifier (Direct Ignition System (DIS)) control signal (A+B) Lead interruption, open circuit :-?

Totally failing crank sensor Mark......as opposed to one with a crap signal.
Normaly a bit intermittent as its often due to a wire break

thats me next check rob :(

Thought you would have done that before whacking another crank sensor on ;)
-
72 is not a Motronic code.
Try disconnecting the MAF as a little test

right checked got spark will go dissconect maf now

no different mark all lights going just battery light staying on ??

Ok, any vac leaks?
Does it start if you apply light throttle?

no but when towing home i jumped it off and it started but as soon as you take foot of pedal it dies deffo no vac leaks
-
If it will run as described it does sudgest a possible vac leak or a sticking idle valve.
When it ran, was it lumpy or nice and smooth?

Sorry, my mistake Code 72 relating to DIS is for the GM Multec ECU but I`m pretty sure on the Motronic 2.8.1 72 is the throttle switch not running on full load

Nope, not a valid code at all for the V6 Motronic (and I just double checked the reference :y)
Remember, there is no throttle swicth

Not doubting you Mark, but why would it throw a "72". Am I right in thinking that 72 might relate to "first generation 2.8.1" i.e. up to say MY 95/96 or am I just waffling :D
-
any more ideas chaps ???
-
so whats this code 72 ????

AFAIK 72 relates to first generation Motronic 2.8.1 ECU

well mines a 99 mv6 3.0 so buggered on that then ! :(
