Have a FE300 with a DT 466 . Driver told me her wait to start only lights up for 2 or 3seconds no matter what . I also found out the filter and water in the fuel don't light when starting bus . Cruise control doesn't work . Are all these connected ? I just ran the test for the intake heaters and I can turn them on with service max . So I need some real help Also when I was running service max it said I had 39.5 lbs of boost from the turbo at idle ?
pull the intake manifold pressure sensor could be clogged with soot, or EBP sensor is clogged (or pipe) the grid heater harness or the relays (not sure if yours has 1 or 2 grids in the intake) cruise is it on the wheel or above key all our buses have cruise disable but still works for ramping up rpm

Thank you for replying Bluenozer . Mine has 2 heaters . The cruise control is on the dash by the gauges .I will check things outand let you know . Another thing with tis bus it had an over heat problem that damaged the head so we sent the head in for repairs and re installed
EBP(3 wire sensor) sensor will be a tube coming from exhaust manifold to above alternator passenger side, IMP( 3 wire sensor) sensor and IMT(2 wire sensor) sensor front of intake on drivers side, is this an egr engine (tube type above exhaust manifold)
