Took my spark plugs out today to inspect them as i wasnt convinced i wasnt running on all four cylinders. Two spark plugs are fireing im shure but two doesnt seem to have ever fired as they where still like new and where covered in fuel. What could cause this? Takeing into consideration i have a newly built engine running efi, new plugs, leads, and has only been fired up twice. im shure im getting fuel but no spark? Please help me!!!!!!!!

coilpack dodgy?- tryed seeing if all leads are firing?
ofab/ofac or summit else??

vroooom ptssssh

fire it up, pull a lead off one at a time and see if the engine note/idle changes. check for a spark if one isnt firing, if u got a spark leave that lead off for a few secs to dry the plug then stick it back on and see if it starts working.

im running ofac managment at the moment. Havnt looked into into anything properly yet as i just checked the plugs before i left and realized somthing wasnt right. When a coil pack fails doesnt it fail totaly? Cheers Chris69

It will be a few days until iv got the time to have another look at it but anything that might help me identify the problem i will try out. Cheers

i'm pretty sure the coilpack works in two halves or something so if it was failing two cylinders wouldn't fire- worth a try as a coilpack should be quite a quick fix
don't quote me just going on memory so hope it helps.

Thanks for you help ill source another coil pack and try it out. The coilpack was never checked so could well be the problem

fook me you wernt wrong! Bloody give me a good zap! Well i found what was wong and it took me about a minute to find and rectify in the end. I had a couple of ht leads around the wrong way

Now runs sweet as a nut. The only thing that i worrying me now is i got it up to temprature for the first time ever and there was alot of blue smoke coming out the back but im pretty shure its old oil from of the exhaust i put on yesturday. seemed a bit oily inside so i hope its that and not the turbo. Also had my exhaust heat wrap ball out aload of smoke. Is that normal for new heat wrap? My dad thought i was gonna catch fire lol

Chris69

heat wrap smokes like mad dunnit- its normal as far as i'm aware lol
its got the cylinder number on the coilplack on an efi engine
I expect the blue smoke will clear but keep an eye on it.
