WTD, Pictures of v1/2 ej20 engine

[DXROLLA]

So i have my engine back in and all plumbed/wired up, but it just wont fire. I have done a bit of research on the net and im sure i have the injectors/coils around the right way but i would like some pictures just to confirm. It turns over but wont fire, its getting fuel as i have taken the plugs back out and cleaned them due to being covered in fuel, so the only thing i could think is the coils?

Any other ideas out there?

Will it turn over and try start? No CEL and maf/map is plugged in?

[DXROLLA]

Turns over sweet, doesnt even try and fire.

Ive read on the net some people get the cam sensor and crank sensor around the wrong way? Could this be possible? I didnt put them in my engine builder did, any way of checking them?

[DXROLLA]

Looking over the pictures of my build i noticed this photo, shows the crank sensor with a bit of damage. Do you think this would be enough to cause a problem?

Have you got spark? People get the cam and injector ones mixed up. You clearly do not as you had 4 wet plugs correct?

[DXROLLA]

Yes four wet plugs, whats your thoughts on above sensor?

[Guest]

If there is an issue with that sensor you wont get any fuel. Check spark.

I have no experience with said version - but as stated - check basics - grounds, coil getting voltage etc. could be as simple as a connector or as complicated as ecu fault...fuses?

Where does the ecu get its signal to spark?

Also i have replaced the idle control plug due to the other one breaking, if for some reason i have the wires around the wrong way would this effect it starting?

Also o2 sensore looks like it has taken a knock when installing the engine : Again could this cause an issue?

Pull a coilpack out with a plug in it. Earth to the mani so it can spark and get someone to turn the key so you can watch it.

Will check tonight.

Next thing i have removed the A/C, this shouldnt cause any issues would it?

[DXROLLA]

Looking at a wiring diagram for a similar engine i noticed one of the wires does conect to the igniter from the idle control valve, if i have this around the wrong way could it be sending the wrong signal and be causing an issue?

More often than not starting issues a re simple problems, so check the basics before you look into looms potentially being in the wrong way etc.

Is the check engine light on? If the ECU is preventing the car from starting, it will most likely be on.

Coils plug in on harness with black connectors for rear cylinders and grey connectors for front, injectors plugs are also colour coded in the same way

Check the spark plugs are in good condition.

It also sounds as if you have had some work done to the car recently, it will pay to back track over what was done and rule out things being put together differently. For example if you have had an auto to manual transmission conversion, the wiring side of things may not have been done properly.

[DXROLLA]

All been put back to how it was apart from no air con.

Pulled a coil off and checked with an old spark plug and it seems to be getting spark ???

Now where? Timing?

Timing im sure i have right, i even took photos of timing marks when i put it togeather, only thing im not sure about is the crank trigger thing behind the crank pully in the above photo, can that be put on the wrong way or is it attached? Again engine builder put that on.

Looking at the picture, it looks like the timing mark on the belt is lined up with the wrong mark on the crank sprocket? There should be a small mark edged into one of the rear timing teeth on the crank sprocket?

Exactly the problem : Took the covers off and yep clear as mud, seriously F$%k off with myself Live and learn i guess, just hope i havnt done any damage

[rex-leggy]

wow that a fair distance out to! you would hear if something caused damage

no nasty noises?

[DXROLLA]

90degrees out by the looks of the marks, wound it over with no plugs in and it wound over sweet with no noises so im crossing my fingers and toes haha

[Guest]

Idk why they put that mark on there. Anyone know? And also the marks on the front plastic cover |||10|||20 etc.

[DXROLLA]

Apparently it indicates the rotation of the belt?
