just wondering what would cause it to have no spark, i have replaced the distributor with no success, does this model have a crank sensor? any other things i could try as im new to working on Mitsubishi
cheers guys

why did you replace your distributor?
test some things. like. ignition coils, leads and plugs.
you can probably assume the new distributor is good, but make sure it was put in good, too.
or do you just mean distributor cap?
i'm sensing disappointment again.

i replaced the cap and rotor first, as it had no spark, that didnt work, so i was talking to the local Mitsubishi service shop, the guy there was pretty sure that it was the coil in the distributor so i got another from the wreckers swapped them and no spark still i have used a brand new plug to test for spark... the reason i was wondering about the crank sensor is ive had the same problem with a Ej20 Subaru and it ended up being a faulty crank sensor?
cheers

the coil volatge must collapse to make spark.
An oscilloscope will tell you if it is. At a pinch an led test light usually will too.
If that signal comes from a crank sensor, then yes. I dont deal with electronics, but it may be a test/clean thing.
Coils can be measured with a fair level of certainty.
Swaping it "because a guy reckons it might..." that guy should be punched.

I would bet it has a crank sensor. Any cheap scan tool should show a crank sensor reading. If you don't have one your just throwing money down the drain. I have had people change a lot of parts for a no spark and it ended up being very simple fix but without proper tools guessing can get expensive. Do you have a tachometer in your car?
