SR20 still not starting

[Bryson]

I'm still workign on getting my Sr20 going and I still have no spark or fuel. I am running the tests the FSM gives, and the Injectors all hav 12v on the hot wire and have proper continuity on the other wire back to their proper pin on the back of the ECU. So according to that they are fine. Next it says the Tachometer should bounce when I try to start it... nothing happens. I next I'm goign to check the ignition stuff like it says... then the CAS... but is there a chance the damn ECU is just shot?? I mean it was packed like *** after all. It was just floating around freely in the crate and it did come from East coast to west.

It is a possibility that your ECU is shot.If you have access to another I would try it.If not I would also look into other possibilties other than the ECU.Is your fuel pump pumping fuel?Check fuses and such.Also when you try and crank it see if you can hear the injectors clicking.Have some one turn the motor over and put a screwdriver up against the injector and listen, if they are clicking then they are working.But also check everything you can such as CAS because that controls fuel and spark also.Hope it helps.

Yes the fuel pump comes on and also IS pumping fuel when I crank... first fuel lines were too large.. the injectors do NOT click when i crank it.. then do not click if I pull the CAS out and turn it by hand.

Check your wiring between the CAS,ECU,and injectors.It should click if you turn it by hand.I would say either wiring or CAS if their not clicking just my .02.

well if you tested the injectors and know they are working...but you still are sure you aren't getting fuel, then either your pump is done or there is a clog or something in the lines. As for the spark, check everything in the electronics to make sure it is still working.(IE ignitor chip, coils etc)

You should also make sure that you have the right ecu. That can make it all not work right.

[stumpz]

make sure your timing is on.. timing is the devil, u'd know this if you read any of my posts.

[Bryson]

I'm positive the ECU is the rigth one, the ignitor chipped I already replaced once because I thought it was it... so thats not it. the coild test fine as far as having proper voltage and resistance... the fuel pump turns on fine and trust me its working well the fuel shot through the opening of a fuel line that was too big on my first attempt so thats not it. if the timing is off it should still spark or the injectors should still click or something right??? I mean I don't get ****... it cranks the same with the ECU plugged in as it does if the ECU isn't plugged in.

ok check your fuel lines that go into the fuel rail you may have them reversed....and did you pull the cam angle sensor off???if you did i hope you just didnt slap the thing in there cause you need to put the motor on TDC and line up the marks on the CAS then install it but if you didnt do that you could be 180 degrees off timing

[Bryson]

fuel lines are right I believe... the in line goes to the connector that is between the intake manifold and my return line is hooked up to the connector on the end of the rail by the throttle body.

I did take the CAS out and then just put it back in... but I took it out to see if the injectors would click when I spun it by hand and I couldn't hear them at all... standing far away... stickign my ear on one... putting a screwdriver to one... nothing. I also couldn't hear then when I would crank the engine.

[stumpz]

ok hi, like i said, timing is the devil.. seriously, just set it so u know for a fact that it is not it.. don't be dumb

[Bryson]

I understand the timing is crucial but I've been told and the FSM both say that if you spin it by hand the injectors should click on and off. Nothing happens when I do that.

[Bryson]

Also I'm having a hard time understand exactly how to properly set the timing.... any pointers would help

[cuzan0]

sounds like your timing is off and the wires by the battery are wired up wrong but start with timing

[stumpz]

here, let me find you the link on how to do it..sec.. http://www.store.yahoo.com/pha....htmlaiight now u'll be able to tell if it's on the compression stroke for cyl 1 by putting a piece of paper over the first cyl and when you turn motor over buy hand, whenever the paper flies off, that's how you know when to follow the procedures on the website

[Bryson]

thanks stumpz I'll do that tommorrow afternoon when I test the wiring between the ECU and the CAS and the ecu and the coils and let you know how it goes.

[Bryson]

oh and after looking at the link I'm about 190% sure my timing is off. we pulled the bavle cover of to put it back in but I didn't see the little marks so I just put it in and closed it up. But still shouldn't the injectors click when I spin it by hand?? anyways I'll let u know what happens tommorrow

The links might not immediately line up with the colored links. With the chain I just pulled, the links were colored black. The new revision to the design is colored silver. It may take a few cranks to get the links to match up with the punchmarks on the cam sprockets. Then you can line up the CAS as they've got on the website.

Check the pressure via the fuel pressure regulator. If there's fuel pressure there, chances are your injectors will be getting fuel. The spark, check the igniter, coil packs, and the CAS.

how do you check if the ignitor chip is bad? just curious...
