Year of Manufacture *: 2006/2004
Engine Size and Code *: z17dtl/z19dth
( Optional ) ECU Type: edc15c7/ edc16c9
( Optional) Fault Codes: none
both don't run, they have had second hand engines fitted (not by us), they have no fault codes, vectra has had an ecu tried as an option, astra has new ecu fitted by dealer and four injectors fitted and re coded by dealer, vectra has had injectors tested several times and re coded with tech 2
both have sufficient compression(astra lacks a little but would still expect to start)both have sufficient start fuel pressure,both high pressure pumps create max pressure, good cam and crank signals and no fault codes
both vehicles crank over(so don't suspect any immo issues and no codes or lights relating to immo)
only clue is injectors fire once then lose injector signal, leave vehicle five ten minutes again fire once and no signal
have diagnostic blindness have been looking too long, must be missing something obvious and i have two so somebody else must have one.
silver bullet please
