Guest Jason1 Posted June 11, 2014 Share Posted June 11, 2014 Anyone know why my coil packs are wired like this? Not standard and so is there a coil upgrade I don't know about? Thanks Quote Link to comment Share on other sites More sharing options...
Philly_1 Lex Posted June 11, 2014 Share Posted June 11, 2014 Broken coil pack clips. Common problem on this motors as the heat eventually makes them break. Instead of just buying new clips from Toyota someone just wired them this way. If it was me I would replace with the genuine clips and check the coil packs for cracks while you are at it.

Guest Budz86 Posted June 11, 2014 Share Posted June 11, 2014 Looks like they've just been wired in without the clips (which tend to go brittle with age) and it's possible the previous owner was too tight to buy new ones. Why you wouldn't when going to the expense of buying new coilpacks is beyond me... Quote Link to comment Share on other sites More sharing options...
Guest Jason1 Posted June 11, 2014 Share Posted June 11, 2014 Thanks guys I will get them replaced as soon as I can, just another thing to add to the list, The list just keeps getting bigger, as it is running good at the minute I shall replace them when I change the plugs, and great advice I will check the coils whilst in there.

dangerous brain Posted June 11, 2014 Share Posted June 11, 2014 Or get yourselves down the local breakers and find a Renault megane as they have the exact same part number plugs. Why would you do that you ask? I dunno about on supras but on aging aristos the looms across the top of the engine to the coil packs and around the corner at the top of the cambelt cover and the next 9-10" of loom suffers very heavily from heat damage to the wiring insulation and subsequently some quite severe corrosion to the conductive material as well. On a megane breaker you'll get the same plugs for absolute pennies that have not been subjected to the sort of temps that a 2JZ lump will provide and you'll be able to clip out a couple of feet of wire and significantly less brittle convoluted tubing as well giving you a decent repair loom option should you need it. This repair is well documented on the aristo forum. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 11, 2014 Share Posted June 11, 2014 Because someone was too cheap to go get new clips. Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted June 11, 2014 Share Posted June 11, 2014 Hi-Jack alert!!! Craig when are you going to admit that supra's are nicer than aristo's and buy one lol Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 11, 2014 Share Posted June 11, 2014 Haha never! I can't get over the crap interior, when I want a 2+2 Ill just get another Soarer, its a better car anyway Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 12, 2014 Share Posted June 12, 2014 That needs the connector shells and terminal repair leads to put back to stock. All available from your Toyota dealer. Use proper Raychem adhesive lined heat shrink connectors, not some Ebay junk, and the proper crimp tool. Quote Link to comment Share on other sites More sharing options...
Guest Jason1 Posted June 13, 2014 Share Posted June 13, 2014 Thanks all You are all saying the same thing to get the proper plugs fitted. So now added tot the list Many thanks Quote Link to comment Share on other sites More sharing options...

Use proper Raychem adhesive lined heat shrink connectors, not some Ebay junk, and the proper crimp tool. And that will cost you quite a wedge I imagine Chris. The megane ones you can find are in perfect condition (most of them) and are literally pennies. Obviously it involves climbing around in a megane engine bay at a breakers and obviously you'll need two cars worth as they are four pots but it is an uber cheap fix (probably cheaper than the abomination pictured in this thread) Quote Link to comment Share on other sites More sharing options...
