Refitted ford fiesta mk3 1992 k reg model with HCS engine, proceeded to engine startup disconnected spark plugs and ignition coil. Oil light went out after a while. All good there. Replaced sparkplugs rechecked engine oil level reconnected ignition coil and ht leads, Tried to start engine. Engine turns over but will not start. Puzzled ???. I understand it will take some time for restart, due to the lack of pressure in fuel lines. Is there another solution., or am i missing something else.Please help ...

 

Most likely something silly that has been missed.
Check for a spark, and 12v permanent live at the injectors with ignition on first.

checked sparks ok. no problems with electrics. got two options to check 1. fuel cut out switch . 2. fuel pump/sender unit on petrol tank leaving till last big job little ones first. any input a must.

 

Press the shrader valve that is used for pressure testing the fuel rail, see that it is under pressure, then as you say there is a 12V live at the injectors, this then leaves the earth, which is provided by the ecu, to open each injector, make sure your phase/cam sensor is ok, if they use one I assume it will be sequential injection, in which case it will have one.

all electrics fine. fuel pump and pressure fine. ht/sparks and ignition fine. engine wants to start but wont on turn over. all injectors fine. phase cam sensor fine. still puzzled. if cant sort it by monday calling me breakdown provider for other options. more input welcome though thanks.

 

HT leads correct ?, these are, don't forget 1243 and not the normal 1342 firing order.

all HT leads are in correct order but still a no go
