MX-3.com

I swapped a KLZE into my MX-3, and just got to the point where we could fire it up tonight. I started it, first try it started up.. But was only running on 4 cylinders. I changed the plugs, no help, I changed wires, no help. It is getting fuel and spark, and I did a compression check with numbers all over 150 (gauge wasnt too acurate, old and leaky, but still forced it to at least 150 on each cylinder, probably is more in reality)
I thought it may be a faulty injector, not so, I even switched entire fuel rails out for the probe ones. I then tried messing with the firing order, is it possible that this was just never right? I have a manual, but it isnt right for some reason, I think it is for the previous model year... What is the firing order, and where is a clear picture?
thanks, I am getting so stressed out I want to beat it with a bat right now

Are you sure that all of the plug wires are going to the correct plugs on the disty? The disty cap should be numbered and I'm sure you already know this, but, the cylinders are numbered like this if you're looking at them from the front of the car:
1 3 5
2 4 6

and the disty should be numbered like this:
4 5 3

6 1 2

Just wanted to be sure that this isn't your problem before we launch into more complicated solutions.

Yeah, now its right, but still the same problem..... should I check injecter pulse? I doubt that it is that because I switched out fuel rails and they are still the same 2 cylinders, 4 and 5 are not firing at all.

It runs on 4 cylinders still, odd, just a hint smoother, but it sounds like it has the worlds largest set of cams, lol

Have you checked if there is gas getting into cylinders 4 and 5?

yes there is, that is why I swapped out entire fuel rails and everything, both work.... Injectors spray (right into my eye, lol)

Have you checked the timing?

would that cause a miss? I havnt checked it per say, but I have moved the distributer around a bit with no change whatsoever.

Have you swapped out disty caps? or maybejust take th eone that goes to 4 and hold it near th emotor and see if it archs when u turn it over.

EDIT: nevermind , read ur getting spark

I am running the KLDE distributer..... thats what I have to do right? It is a brand new cap and newer rotor as well.

yes it arcs, they all get good strong spark

Hmm i dont know..you have spark, u have fuel, swapped injectors and checked compression. I have no idea. How did you check for spark? Did u pull out the plugs on the offending cylinders and inspect them.

yeah, they are black, already and they are brand new NGK's... I switched them again to no avail.

If your 4 and 5 plug wires have strong sparks, I'd say it would be a good idea to check the timing.

With a timing light or just reset the belt or???
