Starting my car

[mk2bal]

I still think its an m.s problem, or a wiring problem. Have you checked for a spark, and fuel? didn't it turn over a while bk?

LOL I know you do! Nah it didnt have spark, changed my coil then took out all spark plugs and cranked the engine ( fuel pump not connected) and they all fired up, but then it was 180 degrees out so obv wouldn't start.

My wiring is 100% correct, there is nothing to it seriously, well M.S anyway, it's a possibily the cars wiring could be an issue. I cut into the fuel trigger wire for my fuel pump, then one ignition wire, which was my window one as they arn't working, so got to fix that! And that's it wiring wise. Other ms wiring is fresh straight from the ms loom.

When I first ever tried it, it started for one second, then never again.

My spark plugs where covered in unburnt fuel when I took them out( clean now) so must be getting fuel. Tunerstudio is saying fuel pump is on when cranking.

Well if it started once then it isn't your timing or the engine. Which leaves the ignition and injection system. Order some new injector seals from vw, pull the injectors out, and check for fuel. If no fuel, leave them out until you've found the problem, and cured it, and proved it, then refit with the new seals..pull a plug again and check that as well. Separate to the injectors too, don't test together or you and your car might burn

That's what I thought, then started fiddling and now put my timing out  Ohwell good to learn the hard way. Ok I'll get some seals ordered in. But I havn't tried it yet with my new coil. Could it have started up for a second then broke the coil ?

If it did its very coincidental, but its most likely your wiring is at fault. It might kill your new one. Sometimes a switched open neutral can kill coils (in a.c anyway) in your case it may have been a poor earth on it,or you put the connections on the wrong way round or something, I dont know.sounds like your motors a bit of a joke, or you dont know where you are with it?! Where was the methodical thinking upon the conversion? The notes, the photos, wiring diagrams, fuseboard info, any other help you may need,so your understanding everything your touching..no offence but my 1.3 carb to 2.0 16v started on the first turn of key, and I knew it would! And I'm no mechanic trust me!

[emery1990]

Well it just aint starting, checked my ms wiring over again and nothing, all earthed to the right places.

I got all the help I could of got, nothing I done was from my own thinking, always asked someone if it was right.


Getting info for an ms conversion on the 9a isnt easy, no photos etc, just a wiring diagram that was wrong anyway

I think a pro is needed  Call Nick at RTech i believe he knows all about megasquirt as thats what he wanted me to run my ABF on..

[emery1990]

Well checked wiring again and checked with ms pros if earthing was ok, they said it needs changing a bit but wouldn't cause a shortage, so havn't touched any other wiring, so god knows why it would be shorten, unless there was an open circuit that has always been there and whilst I've moving stuff bout it's showed up.

Don't know whether to just start it up and see if it blows my new coil! After changes to my earthing has been done.

Checked 4th time, 100% no sign of shorting on ms side of things.

Will that do the trick, only needs to work once.

if you need to check compression then yes mate
