The green wire came from pelican parts. I actually got it running. I adjusted the whole distributor assembly. It's idling about 1000 now. I think the distributor assembly is a little out of time.

You should be able to get close to perfect by hand adjustment.

There was a batch of bad green wires, wired wrong, a few years ago. Just checking to be sure you didn't grab them from a backwater parts place.

The oxygen sensor needs to be hooked up and working on the Ljet cars, at least in my experience.

mixybro4 08-30-2013 07:50 PM

It's always the way over at the moment. I think I need to pull the cap off and adjust it a little more and then put it back on so I can hand adjust it more. The wire looks pretty new. Where is the oxygen sensor?

mixybro4 08-30-2013 08:04 PM

All the way over **

MPDano 08-30-2013 08:06 PM

O2 Sensor should connect pre-Cat somewhere, the wire is then fed on the side of the tunnel and comes up to left of your CE Panel.

The car keeps saying something about OXS when you start it but then goes away when you rev it.

try resetting the box on the passenger side of the seat or near the CE panel find a white box with a black button on it press the button this resets it

Mrmerlin 08-30-2013 10:01 PM

here is a link with a picture of the box its on the passenger side of the car either by the CE panel or under the cover next to the seat.

see the 3rd and 4th pictures

Distributor shouldn't be hitting against a motion stop.

How would removing cap help?

Have you checked the timing mark alignments?
Set crank at TDC mark; cam gear marks will show (notches are on back, not front, of cam gears)
(if they don't, rotate crank again one rev, then the marks should show)

So, with crank at TDC mark, cam gear notches should align with alignment marks on the rear cam gear covers. Rotor on distrib should align with notch on distrib housing.

Trying to determine if your cam timing is way off (timing belt misalignment or broken cam snout)
Or if distributor is installed at right place.

I was going to suggest this earlier. It's basic timing. Sounds like your off a gear on the Disty.

Which notch on the distributor housing are you referring to? Which end of the rotor?

Mrmerlin 08-31-2013 10:57 AM

when you remove the cap there is a small cut line on the distributor body,where the cap seats
the leading edge of the rotor should line up with this cut line when the engine is at TDC
This is to verify TDC for the distributor or the rotor pointing at #1 plug wire

mixybro4 08-31-2013 11:52 AM

You mean that little notch were the small black lid sits? So to get it back in time I have to take off the timing belt covers and make sure it is in top dead center? Or is there an easier way todo it?

Landseer 08-31-2013 04:14 PM

Best to take off the covers.
Fairly easy to do.

Mrmerlin 08-31-2013 07:02 PM

put the crank at TDC and remove the passenger cam tower cover,
line the rear of the cam with the pointer,
loosen the DS cam cover and see that the rear of the cam is also lined up,
then remove the cap and verify the leading edge of the rotor is lined up with the hash mark on the distributor housing

mixybro4 09-01-2013 02:01 PM

I put the crank at TDC, (the first hash mark on the crank, there seems to be 4 or so different fractions, I put it on the first one). The cam shaft marks do not line up, i went around several times stopping on the first mark and they still do not line up. If you line up one cam marking the other cam lines up with it but the crankshaft does not line up with the marking. Seems to be off by quite a bit. How should i go about adjusting it?

Mrmerlin 09-01-2013 02:11 PM

this is where TDC is for your engine if the cams dont line up then turn the crank one revolution and check the cams again.
If the numbers on your crank dont look the same as this,
then the damper is installed backwards
What this picture is showing is ( 0IT ) is TDC

First picture is top dead center mark on crank, (my markings are facing towards the radiator instead of in towards the engine like yours.) The second picture is the passenger side cam marking, in the third if you look hard enough you can see the mark on the cam. Timing on the cam appears to be advanced about 3 inches( as close as I could get it, I went around about 4 or 5 times)

Warning your crank damper is installed backwards,

the best you can do now is get one cam lined up then the crank will be at TDC,

but it wont be indicated see the picture i posted.

NOTE your numbers are upside down,

thus so is the damper.
To fix it remove the damper and flip it over after lining up the cams,

the OIT should be pointing to the timing cover pointer once the damper is flipped over
