It took me longer than expected due to only working on it on Saturdays only working on it in fair weather! If I had the luxury of a garage it would have been done much sooner. I would definitely recommend giving it a go yourself; this is the first car I have ever decided to work on for some reason. With the mentality of, the worse case scenario is a new engine followed by I could save a fortune in labour costs, spurred me on. Ontop of that the self achievement at the end of it all. Surprisingly it was remarkably easy(ish) to complete in fairness (easy to say now in heinsight) but learnt a lot, Thanks Alex for his speedy delivery of parts at a reasonable price too, thoroughly recommended! So good to finally get a good drive in it, I thought it was amazing before I had the issues and now it feels even sweeter after. Mod planning will slowly start, albeit subtle to begin with..

Another double orange combo buddy!

We are finally back in business! Cam covers & Spark Plugs DONE Injectors DONE Its amazing what an unskilled mechanic can do with a lot of patience, swearing and a extremely friendly and useful forum, can do!!! (thanks all) So officially can I join the Z club???

I rechecked everything but noticed there was a bit of coolant residue on the throttle sensor connector so I dried and cleaned up the contact points and hey presto it started! (after charging the battery as that went flat!) The covers have now been changed successfully running smoothly for a short period and then I start getting a misfire. When the EML flashed i run my diagnostic fault scanner and it shows pending faults for PO304 and PO300. When the fault then sticks and registers the error it only shows PO300. strange as it shows PO304 as pending and disappears. So I'm considering coil pack replacement on cylinder 4 in the first instance as the spark plugs only changed a month ago and then work it back from there. its either going to be coil pack or injector? unless any other suggestions? Also I need some clarity of what cylinder number for actually is? Is it the middle cylinder on the drivers side (facing the engine, UK Car)??

Thanks I will check this also. I used my wireless obd2 reader I got from amazon ( I will update that on another thread.) but mu say works very well. Seems I have some issues with the throttle body sensor and then also threw a could of potential malfunction. I think first thing once weather has cleared is check connections to this I case anything got dislodged when moving/ removing the plenum as I kept this bolted to the together. I will update more as we go along.

I checked everything by hand and replugged everything. I'm trying to think of a process of elimination of what it could be. I have read this a few places on various forums but I don't understand how this can be working and then all of a sudden then become faulty (i know stranger things have happened but its alien) I have ordered a OBD2 reader and hopefully that may through up a error code giving me clearer direction.

I have had a browse of the forums but thought I would see what people's thoughts maybe... Last weekend I changed my near side cam cover and rebuilt the car and car started fine however I still required to change my off side cover. This weekend was turn of the off side cover, managed to finally, found it more fiddly that the near side one...... Went to start it and it cranks but doesn't start. It's like something is stopping it from continuing. The first thing I did was retrace my steps and checked every connector that I would have removed to ensure they are in and nothing is loose. Today I tried to start it with the same result however on one attempt it actually cranked over for sometime (20 seconds or so) albeit it very reluctantly and lumpy. When it does crank over I sometimes get white smoke out of huge exhausts so it must be igniting something at some point. The most frustrating thing is I know it's something small that's preventing it from starting but trying to ascertain what it could be is going it take the time..

thanks all for the welcome. I had the misfire and replaced all the plugs and noticed the 2 plugs swimming in oil. The car ran like a dream and it was only a matter of time until the oil seeped back in. KyleR - Unfortunately they are the 2 plugs opposing each other at the rear of the engine (nearest the bulkead, I'm unsure which cylinder number reference these?) So that's 2 covers and 2 gasket seals and then 2 new coil packs for good measure incase the existing ones are damaged from the oil (unless anyone has any tips on best ways to clean the oil off them) Been in contact with ZMANALEX and discussing products. Having that driving experience after changing the plugs is spurring me on for the fix rather than deliberating on the negatives, things happen! AliveBoy - had the car a number of weeks now and I would be lieing if the quality of some of the zeds on this forum has not got my imagination going and a few hours spent "window shopping"

new owner of a 53' zed in orange. Whilst I have had some initial issues with the car which I'm currently rectifiying (misfire with oil in 2x spark plug chambers); my brief driving experience has been fanstastic even with the small window of full performance it has left me with a permanent smile. Not looking to do any crazy mod's to be fair, some minor cosmetic tweaks potentially however once I have her in full working order and sneaking of sunshine I will get some photos. Have found this forum massively useful already and look forward to engrossing further.
