Title: running problem omega 2.0 16v
Post by: jjames on 29 May 2011, 17:38:30
Engine starts runs ok until it gets upto temperature then everything goes haywire
i.e. eml comes on, rev counter, fuel gauge & temp gauge go crazy, misfires, and eventually cuts out. It will start again with alot of trouble if you keep revin it up. If I let the engine cool down for approx 10mins it starts ok but feels rough with no misfire. It will rev until back upto temperature then the whole cycle starts again.
Had the code read and it came back as Dispack so changed the pack with GM Dispack went ok for 1/2 hour but faults back.
Anybody have any ideas please?

Sorry but I had the code read by diagnostic centre at the cost of £10 and the code came back as P0351- ignition coil High input

Take the lid off the trunking that runs along the side of the engine, and have a good dig around looking for any wires that have chafed/shorted to others.  The wiring from the ECU to the DIS runs down there.

Was the DIS that you took off physically damaged in any obvious way (casing split etc.)?

Edit, oh and use a paperclip to see what codes the ECU is currently reporting, if any, for free!
See maintenance guide index, Paperclip Test.

thanks for that we will check it 2moro
Old Dis only had slight seperation from round the edges of the seam
Didn't do the paperclip test as we read on another forum (VXON) that the test would not work on models 1999 onwards and ours is a 2000 facelift .
But will now try the test to see if it will work
thanks
