Timing for EFI blue 202

[DANNY8]

We got the new motor in PEAKN6, finally got it running after working out the dizzy was 180 degrees out haha. It was running like a barge, it was on 4cyl, checked the leads and plugs, replaced a few leads, then a few plus and now it's running on all 6 now but we're not sure wat to set the timing at??

The blue motor's are 6 degree b4 tdc, and the EFI motors are 12 degrees b4 tdc.....so wat should we do the timing at?

Should we just have a play and try and get it the best we can and leave it at that?

[DANNY8]

We tried having a play with it 2night, but we can't find a muffler that fits over the end of the extractors to shut it up, so we just adjusted the clutch, had a qwik 5 second drive out of the driveway in reverse and that was it.

The timing is so far out that if I put my foot down it doesn't build up revs lol....yet enuf to idle pretty reasonable.

Will have a good suss 2morrow.

G'day
I had a black engine in the old HZ with a 5 speed supra box behind it,i took the fuel injection off it and run blue manifold/extractors,and ign on it.
It took me a while to get the timing right but i did it ear,mind you it was on gas as well,its pretty easy once ya get it right ya wont have to touch it again.
I just turned the dissy till the engine labours a bit then back it off,take it out for a strum and see if it pings,if it does bring it back a bit more.
Regards Phillip

Cheers mate, we've been playng with it all morning but can't get it running right. We've put new leads and plugs in it, and have advanced and retarded the timing heaps but it doesn't help.

When I put my foot down it doesn't even pick up in revs.

Any ideas? I'll go get a vid

[DANNY8]

Here's a vid I got about half hour ago...
YouTube - PEAKN6 - New EFI 202 running like shit

We've had it running marginally better, but still not drivable.

The motor itself use to run perfect (even got a vid of it b4 we pulled it out of the car we got it from a year or 2 ago)...smooth as. The injection gear is a mix of the old setup, and a few bits of my gear. It has my throttle body and intake. The intake was acid dipped and cleaned, so it's clean inside and out. The dizzy is wat we had on the EFI motor only days ago and was running good, the leads, plugs, rotor arm and dizzy cap are all new.

[dreamcatchu]

whatever the hell it is it don't sound good, sounds like it's dieseling,

[PRH]

G'day again.
Just listening to the youtube it sounds like ya got the plugleads out of wack,if it was me i'd whip them all off, do a compression test (i know ya just done it up) but ya need to start at the beginning. Set it on no 1 TDC,do this with the plug out,check compression (the timing marks might be wrong) and retime it,have you got a new set of plug leads ?
Best of luck regards Phillip

I think PRH has got it, check the firing order out..

[DANNY8]

Thx for the help guys will have a play with it 2morrow.

Yeah it has new leads and the we've triple checked the firing order. We haven't got a tool to test the compression, but might try and borrow one from a mate.

Also gonna put the timing light onto the injector wiring to see if they're all working, coz we're pretty sure it's the first 3 cylinders not working, and the injectors are wired up in banks of 3, so it could just be a dodgy wire going to the first 3 injectors

[Wrayza]

That theory on the injectors holds water mate. But I don't think the timing light will be able to show you if there firing. It works on the collapsing magnetic field the leads throw off, who knows maybe the injector pulse is enough to work too. Otherwise try a multimeter or test light.

[AirStrike]

When we did a mates 202 we just started at 6 degrees advance and kept adding timing till you could hear it pinging and then pulled it back a degree.

[DANNY8]

Tried putting the timing light on the injectors but did nothing. Tried a multimeter and the only info I found was that both pins on the injector plugs had a negative current, then when cranking in had a positive current....I dunno how to use a multimeter, so that's the only info I got from it. I tested 5 and 6, then 1 was the same so didn't bother with the rest.

I tried resetting the timing once again, but can't even get it to fire anymore.

I'm thinkin it might be time to pay someone to have a look at it coz I'm outta ideas.

[DANNY8]

Is there anyway to see if any of the posts on the dizzy cap aren't putting out enuf spark?

I've just seen some of the wires going to the coil are pretty cactus, like only like 3 strands of wire out of the whole wire itself are making contact coz the rest are broken, I guess this could cause a huge voltage drop hey?

[14secvp]

with the ignition on there should be power to one pin in the injector plugs and i think if you open the flap on the airflow meter with ignition on the injectors will pump gas watch out youll flood the engine if you have the injectors in take the wiring off the injectors then hold the flap open and see if you have the other pin earthing to drive the injectors .

[DANNY8]

We're pretty sure the injectors are working coz the spark plugs are covered in fuel and coz it's starting to fire again.

The problem now is when when we switched the coil over the tachomatric relay wire seemed to find it's way onto the positive post on the coil.....now it's making a buzzing sound....that isn't good I take it?? It still fires a bit, but not enuf to run.

So at the moment we're trying to track down another relay.

[DANNY8]

Well yesterday we got another relay (thx Doctor Bob), and 2day we went and had a play. Brad spotted an earth cable which had come off....I followed it back and I found myself at the relay haha.....put a new clip on the lead, chucked it back on the battery and the relay stopped making the buzzing sound. So now we have a spare relay lol.

Took the oil cap off and looked inside while the motor was turning over....the rockers we could see weren't moving (we also took the plugs out so oil would pump asap)....took the front side plate off and the lifters aren't getting oil pressure. The outside of the lifter is moving up and down, but the middle isn't moving.

So yeah it seams oil pressure was prolly the problem all along. Took the oil filter off and it was bone dry. Filled it up with oil, pumped more oil in the pump, but still couldn't get pressure. So it seems when the motor idle'd to start with it prolly had no oil....so hope we haven't stuffed it.

Just went and bought some grease to pack in the oil pump, then chuck it back on and try again.

[DANNY8]

Well the grease seemed to do the trick.....after a few seconds of turning over, the needle on the oil gauge started to jump up...then the rockers started moving.

Chucked the plugs back in and put everything back 2gether and it started first shot. Did the timing and it's still pinging a bit and the occasional miss, but for now it's ok. It's booked in for Monday to get the exhaust welded up, so as soon as that happens we can start driving it around again.

Thx everyone for the help!
