0 mikebh8 Posted September 23, 2017 Report Share Posted September 23, 2017 (edited) You posted it in 4th generation but what year, model engine as may differ (probably not), but to make sure is under the right section? The software I use does not show the faults starting with P1 ( I still have to look into getting a different one), however, I do have a "test to button" option.So if you could tell me some more symptoms or noises coming from the car, would help identify.Does the engine crank?does the pump prime?If is no movement whatsoever ( but relays do make a sound), I would knock the starter motor with a wood stick.

0 ryden Posted September 23, 2017 Report Share Posted September 23, 2017 (edited) Possible issues for your code below : P1651-MIL/DIAG LAMP VIA J1850 BUS IN FRAME RESPONSE ERROR P1651-MIL/DIAG LAMP VIA J1850 BUS STATUS ERROR Seems there's a few possible causes - ECM, Instrument Cluster, wiring, communication issue.

0 gordy Posted September 24, 2017 Report Share Posted September 24, 2017 Hotrod 21st Feb 2017 on tother forum (dot com) had this come up (together with P1685) and he ordered an air flow meter. Then there was a mention of a fuel temp sensor fault for code. Wonder if trying to start engine with meter removed would confirm this.

0 Shanless Posted September 25, 2017 Author Report Share Posted September 25, 2017 Thanks guys... Sorry for not giving you more information It's a 2005 2.8The car drove perfectly...then the instrument cluster failed..no lights or speedo but drove grandI changed cluster but still didn't workI drove the car to a garage to get diagnostic doneI might as well have pissed to the wind cause they were crap When I went to collect car it wouldn't start It cranks over very strongly but won't fire upI got another guy to look at it and that code came up Quote Link to comment Share on other sites More sharing options...
0 mikebh8 Posted September 25, 2017 Report Share Posted September 25, 2017 Fuel issues or immobilizer.When you turn the key to on position (without the cranking part), do you hear noise like a buzz coming from the prime pump?When you turn on the lights, do you get lights on the air control panel?That could be the fuse controlling the acc, do you have radio working?
