SR20 Injector issues (HELP!)

[Wolfzter]

I know there are some smart guys here...I fear I may not be one of them:facepalm: I have an SR20 non-turbo engine planted into a Lotus Replica. I have scoured the internet for info on my non-pulsing injectors and may be more confused than before I started.

I have 12 volts going into the injectors and they do not seem to pulse during the crank cycle. I have a mess of spare wires coming out of the ECU and can not find any Pinout diagrams for the V6 Module...so it's a real crap shoot for me.

Any of you encountered a similar problem? Where should I even begin?

[TheRealSy90]

Just for information, all four injectors open at the same time during cranking on sr20's.

[Wolfzter]

OK...that makes sense. So, the pulsing should occur during the run cycle? Maybe I'm barking up the wrong tree?

[Wolfzter]

Maybe I need to pull an injector and see if I have fuel flow during cranking? What do you think?

[TheRealSy90]

If you believe they aren't working then yeah pull the rail off the intake manifold with the injectors in it and make sure they all spray. But yes during cranking all four will spray at the same time.

[Wolfzter]

Well this is bloody embarrassing: I think the fuel has gone off...it sputtered a bit during my repeated attempts at cranking. I will drain the old stuff and put in some new. Maybe it will run then

I do thank you very much for your info!!! The behaviour now makes some sense. I tore the harness apart and double checked all my wiring and it seems to be correct. I have the Fuel pressure set a bit high at 50psi...might try trimming it a bit when (and if) it runs
