Starting Problem.

[charlie]

HOPEFULLY NEW YEAR, NEW IDEAS, NEW LUCK.
As some of you might be aware, i rebuilt my engine late last year.
All is well apart from the car will turn over but will not start on ignition key.
The car will push start.
engine only done 250 miles since rebuilt. Still feels very tight.
The following is list of items changed/checked.
1) G40 sensor -------new
2) G28 sensor--------new
3) G4 sensor ---------new
4) Ignition switch-----new
5) coil pack----------new
6) spark plugs--------new
7)fuel filter-----------new


Only fault codes showing are G28 & G4.
Could someone please share some light.
Any ideas or suggestions will be appreciated.

surely it has to be the wiring to one or both of these sensors.if wiring shows fault codes.

Charlie, make sure the relevant voltage is present in the wiring WHEN CRANKING.
I would say it drops to 0V, that's where the problem lies.
