Sr20det running on 1 cylinder

[Sr20probs]

My sr20det is running on one cylinder they are all gettin spark. My timing could be off though. Could this cause this any input would help thanks.

SR20DET will not actually 'run' on just 1 cylinder. Could you clarify what exactly you mean by 'run'?

Well it is only firing on one cylinder I should say

Pull the fuel rail off leaving the wires and fuel lines attached. Crank the engine, and you should see puffs of fuel from the ends of each injector, all firing at once. There should also be no fuel dripping at all. Dripping = bad injector O-rings, cheap to fix.

If you are getting fuel from all four injectors, perhaps the cylinders are flooded. Dry them out with a hairdryer after removing the plugs. Also check your oil on the dip stick for the smell of gas - gas in oil thins it and leads to a spun bearing very quickly.

If you have spark and fuel on all 4 cyls, and the cyls are nice and dry, if it still wont start it could likely be the timing. Use the FSM procedure and don't skip any steps - if you have to skip a step something is wrong that needs to be handled.

Good luck!

2 common reasons this happens on fresh swaps:
1. you are using a J4 ecu on a 62 harness (or a 62 ecu on a J4 harness)
2. you are using an N/A (distributor) ecu on a coil-per-cylinder turbo harness

Hmm I haven't looked into that I'll give it a shot
