Miss fire Opel corsa 2005

Assuming the car is properly serviced and it's not something silly like a spark plug, it's either a coil, HT leads or the fuel relay, 90% chance it's the coil.

Don’t believe anyone who tells you it's the computer box.
 
I have gotten the same issue with my corsa recently. Ive gone through changing the spark plugs, Leads and even the fuel pump. The last thing I tried to change was the coil, but the new coil I got doesnt seem to create any spark? The engine just cranks, it doesnt start. I took it back to exchange thinking its a faulty unit and the second units also gives no a no start. With the original coil I get a heavy misfire, but at least the car starts. Any ideas on how to sort this?

And so, seeing as this is not a political or race question I have to agree....................
While you at it check filters and fuel lines.

The problem comes when you do too many things at once, because you might unwittingly introduce a fault by putting in a faulty part or messing up something.

But at least you haven't fiddled too much so it's not hard to retrace your steps. If you get a start, even with a misfire and nothing on the new coil it means the new coil is faulty, and the new one you exchanged with is also faulty.

The new pump is a good thing anyway, proactive maintenance so no loss there, put back the old coil and go buy a fuel pump relay because the symptoms match what I once had, it's around R150 at Gold Wagen. Replace the relay with the old coil on and see what happens, then put in the new coil to satisfy yourself on its operation.

The relay is on the drivers at the bottom on the right on a Corsa B, not sure about the Utility. It could still be the coil since you don't have a working new one.

Lastly, I have found Midas to be a little dodgy on parts, stick with Goldwagen if you can.
