Good Afternoon all,

Last week I went to work on the vr4. I replaced the spark plug wires and put a new o2 sensor on. At this point the starter was on its last leg, it would not engage properly. So I ordered a new one ($66 on rock auto) and got around to it today. After replacing the starter the car will crank now, but will not start. I can see I am getting fuel pressure, not 100% sure on spark. I believe I have the firing order wrong on the wires. Can someone help me out with this. I will include photos of how the ignition coil is set. Sometimes when I crank the car it will read the RPM really high, other times normal ?

Both pictures show the plug wires not connected. Might want to start with that. /ubbthreads/images/graemlins/grin.gif

One coil does 1-4 the other coil does 2-3. In the OEM location the order is 4-1-2-3 left to right. Your coil looks flipped so try 3-2-1-4. If that doesn't work try the OEM order.

Plugging them in would definitely be a start in the right direction! I tried the OEM orientation and that did not work. Will try that order and see if that nets me results. I ordered a spark checker just to be sure. I think this is a 2g ignition coil after reading some posts about the differences.

Thanks!

You can just put a screwdriver into the spark plug boot and see if it sparks on the valve cover to check for spark. Even if it was in the wrong order it would backfire. I also once bought a non running 1g with similar issues and it ended up being a loose connection at the cas. Pull the plugs after attempting to start and check to see if there wet.

Quoting JRuby:

2G coil should be the exact same minus bracket? Since it's waste spark you could technically swap the paired wires and it wouldn't matter. 1-4, 2-3 or 4-1,3-2.
