I do not have spark?
As I mentioned before my distributor is brand new, how would I test for a CKP?
Any further help would be appreciated.
Again thanks for your time. |
The white/blue wire will be your ignition positive,
The yellow/red wire will be the earth which is controlled by the
ECU, you'll need to change the setup your test light to check for earth when doing this test - test light tail to battery positive, not on the battery negative.
If the solenoids are clicking in the injectors, you'll have injector pulse, they won't fire/click without that
ECU controlled earth.
Ghetto way of checking spark, pull a spark plug lead off, jam a long philips screwdriver up inside of the plug wire where the spark plug would usually connect, then the shaft of the screwdriver that's exposed, put it close to something that's metal on the engine like the intake manifold (
NOT NEAR ANY SENSORS) - about 1-2mm away and crank the engine, see if you have spark jumping from the screwdriver shaft to the intake manifold across the small gap.
Make sure you don't touch the shaft of the screwdriver or you'll get a nasty surprise
You haven't got the
distributor in the engine 180 degrees out by any chance?
CKP needs to be checked with an oscilloscope to see a waveform, given its new its probably not going to be an issue,
If you have injector pulse and no spark, next thing to check is an ignition module, it might be external to the coil, is there an electric module going from the
distributor to the coil or in that area?
The ignition module may be built into the
distributor though if its got 7 wires,
The only cars I have with distributors have external ignition modules (my dizzy only has 3x wires), they are located next to the ignition coil on my car:
I've marked the ignition module and ignition transistor with yellow arrows pointing to them to give you an idea what they may look like and where they can be located (if they exist externally to the dizzy, having 7 wires means it could be internal).
Make sure the
distributor is installed in the correct position and its not 180 degrees out.
