Post head gasket replacement.....No start 02 impreza rs

[Sbimpreza]

Recently did a head gasket change as well as a resurface of the head. I put the engine back together by the book and now it won't start it only turns over. No fuel on the spark plugs and injectors aren't pulsing. No spark on the spark plug even though new ngk spark plugs and wires. Thought it might be the coil pack ignition so I replaced that(no dice). Thought timing was off so I checked that and after numerous engine turn overs the lines all line up on crank and cams. Replaced cam and crank sensors and still no dice. Double checked the fuel lines and they are correct. Only thing I came up with was that the wire connector going to the coil pack ignition only lit up in 1 of the 4 terminals when using a volt check light. Could my wire harness be bad? Everything looks fine on it and no major slices. Have no clue guys, so any suggestions I will try out.

Does your model have an igniter (sometimes called an ignition control module)? Mine recently went bad but replacing it got me going just fine. However since you lack pulse at the injectors and no spark then there must be something else. Trace back the connections in the harness and see if something is unplugged.

Triple check the large connectors at the pass. side rear of the intake manifold.  Make sure they are all snapped in place.

I think it's a wiring problem. I have the key to on position and Checked the volts with a light tester in each terminal of this two big connectors and only some on the brown connector light up and on one on the grey connector lights up. Does anyone know where to find the wire diagram on those 2 wire clips on passenger side behind manifold.

triple check crank sprocket timing - you never use the arrow/reiangle on the front, use the dash/grooved 'tab' at the rear for TB alignment, then do a tooth count after rotating the sprocket 2 times.

 

also, check the large hose from the IACV to the intake tubing connection.

 

ground connections are also critical.

It was working fine before the engine work , correct ? If so then unplug each connector and inspect the prongs inside , they can get pushed out of place when reinstalling. Also, make sure you attached the coolant temp sensor wires completely on the coolant crossover pipe under the intake manifold.

Yes I checked all hoses are connected and the timing lines line up perfectly after several engine turnovers on engine block and cam wheel as well as crank wheel so it can't be a tooth off. I really believe it is a wiring issue. Do you know which wires should be showings volt on the major wiring connectors behind the intake. Both cam and crank sensor don't get power when car is turning over.

Try the attached. Should be a FSM  in there...also yours is the same/similar to Forester.
