Iv recently just had the head of my s2k, now its all put back together, everything plugged in, plumbed up etc etc, but for some reason it wont start, its turning over perfectly fine but wont start, iv checked fuel and spark but im not getting any spark. tried my coil packs on my friends car to see they are the problem but theyre are sparking fine on his :s any ideas? its not throwing up any codes on my code reader either.

 

The timing might be off.

 

How long was it sitting while it was waiting for a new head? If I go so long without mine I tend not to function properly.. same logic? Could be bad gas if it was sitting for a while. Or like he said the timing is probably off.

 

Human head and s2k head are 2 different things! O_o

 

Timing has been double checked and it's spot on, was only without the head for 2 days so not that it's been stood for long, Is there a fuse or something for the loom to the coil packs?

 

No ideas? This has got me puzzled

 

Does the s2000 use a trigger wheel or something for spark? If so is the sensor for that connected? I'm still learning about the motor in these cars.

 

Everythings connected, there isnt a single plug left unplugged, wish it would be something that simple, its got me baffled. times like these id be happy for it to be something so simple and make me look an idiot!

 

Is your immobilizer turning off when you put the key in the ignition? Hell it just happened to me! Luckily the ECU "remembered" it's keys after 24 hours of being plugged in.

 

yea the green light comes on just as normal, i tried the ecu reset and its still doing the same, is there a way to programme the key back to the car if it has forgotten the key? the battery was off for a few days whilst i was doing work to the car
