Update: swapped out coil and it starts now. Very odd as they both read the same on my meter, can only assume the old one is collapsing under load. Thanks for all your help folks.

Yep its getting air, pulled the air box off to check. Its not flooded, has been left several days at a time between attempts to fix it and Ive pulled fuel pump fuse and cranked it over to clear the cylinders. I'd do a compression test but need to order a tester. Wondering if its skipped a tooth on the belt and the timing is off.

Cheers for all the help folks. Bit of an update... Have had dizzy apart, tested impedance on dizzy coil and it's within spec (0.7 on primary and 15k on secondary). Just to be clear, the dizzy coil and plugs ARE sparking. Also put noid lights on injectors and they are firing correctly, along with fuel pump running, so fuel is def going in. Given that I'm getting a spark on all my plugs and dizzy coil is within spec, is a new dizzy likely to be the answer...?

Thanks guys. Pulled all the plugs this morning, cleaned them up as they were a bit fuel fouled, tested them with my multimeter and they are all reading around 4.5k so look good to me. Engine management light is off. I shorted out the 2 pin connector anyway, but the light didn't blink so there are no codes stored. Dave - yes engine is turning over fine, just no start. Was driving back from doctors when it started to lose power intermittantly on gear changes (so when coming off the throttle), carried on another 500 yards or so, then it died. Started once after that, for all of 5 seconds, then it was all over. Found a chap breaking an MB6 who I asked about a dizzy, but he's since sold the whole car so will have to look again. At the moment my list of suspects is dizzy, crank sensor and ECU. Looks like I'll be taking the wife's car to work tomorrow!

Cheers Noodles. Forgot to mention I've changed the relay, tried that before towing it home, and its got fuel and ignition so def not that. Can it still be the dizzy if I'm getting a spark though? Suppose the spark could be weak, but I'd expect it to at least ignite a couple of banks when cranking over even if it doesn't fully start.

So rather embarrassingly I broke down a couple of miles from home this week, loss of power and then died, refused to start after that. After getting towed home I've started checking the obvious things. Spark is present on dizzy coil and at plugs and fuel pump is running (sprayed petrol all over my engine bay checking that one!) so we have fuel and ignition. Could it still be the dizzy if I'm getting ignition on the plugs? Spark looks strong to my eye, should at least try and fire up if nothing else. I recent changed the thermostat if that is relevant, checked the plug and ground attached to the thermostat body and both seem fine. Can see cams turning through oil filler cap. All other electrics working fine, no dead fuses. I thought crank position sensor but can't find where it is. Any other suggestions?

Do you still have all your teeth?

We have a winner! Factory fresh! I think you've read that wrong mate, 167,000miles. Face - palm.

Cheers noodels

Im sure someone else on here tried that, but it can't be done as the wiper motor is keyed to fit a certain way. Still, perhaps easily fixed with a grinder...

Bah - double post. Stupid phone.

We have a winner! Factory fresh!

Hmmm... It's not annoying enough that I'm going to bother seperating the box unless it gets worse I don't think. Noodels - would you happen to have a link to those energy mounts?

Ah - I think the MX5 is one of the cars Im going to regret not owning in my life. Will have to wait til the kids are grown up I think.

Cheers Nick. Just been perusing your build thread and car does look the ideal height.

I get juddering from when taking up the clutch from a standstill. Been there since I've had the car, not got any worse and not slipping at all so just ignored it. Am I looking at a new clutch or could it be something simpler like worn mounts? (I realise I'm asking the 'how long is a piece of string' question a bit here)

Correct. Though if you just have the standard mgzs shocks and springs you won't have gone low enough to need them.

Yeah I did toy with the idea of getting Eibach pros to go on them. That's what you've got right? How do you find them? Ride ok? Any clearance issues?

Cheers, I might give a 9v battery a go to be sure I guess. They werent working on the original head unit either and the cabling at the harness is fine as I've checked that. I've got a meter in the garage somewhere, but it's buried under crap and kids toys! Joy of parenthood.

Head unit is setup fine, rear speakers are intact at connections. 99% sure I have a break in the cable somewhere, just need to track it down if I can get 5 mins peace from the wife and kids!

Ta, will take a look.

Seems like a good deal considering a lot of places are selling LCAs alone for that price. Only question is quality? http://www.ebay.co.uk/itm/380467919912

Yeah I'm perhaps being too harsh on their condition, but I'm more concerned with whether or not they are the right parts given what others have reported.

So, I bought some MGZS 180 shocks from CW some months ago. One thing and another meant I've only now gotten round to looking to fit them. However, from reading the threads further down this page, it sounds like I might be wasting my time. See what you think: Rears marked RPD000120 with blue springs. Fronts marked RNB000360 (I think) with blue and orange springs. No leaks on them, but tbh they don't look in great nick.
