this has been happening for the last week or so now.
I drive it for hours and all is fine, then park it and come back say 15mins later and wont start... no spark from the coil. Cool it down for a few hours and it starts again? This is an ED using standard ignition system. I replaced coil, leads, cap, rotor, module, rebuilt dizzy about 6months ago. Any ideas whats going on here? |

it could still easily be a faulty coil hey.. also check obvious stuff like battery terminals and wiring etc, best way is to see if the coil is getting what it needs (ie the right pulses of power to make it trigger... or plug another coil into it and try that

I know you say that no there is no spark so I'm probably no help, but I had a similar problem and it turned out to be the fuel pressure regular.
All the best in solving you prob Ben |

When its hot and doesnt start - is it trying to kick over, but just not make it?
or does it just not do anything?

Crank it over and it doesnt even try to kick.
There's no spark at all. I've tested my way back to the coil, next i'll have to test whats going into the coil... whats a good way of testing the coil, other than trying another which I dont have? Are the modules reliable? The cars been sitting for about 3 months so all the new elec gear I put on it could be all coroded by now. |

sounds like the tfi modual if thats what they call them, its usually apart of the dizzy but not always. just check basics, like is there a crank signal, power earth.

this is most likely not the cause of your problem, but thought id add this anyway. i had the exact same problem, wouldnt start... and if by chance (a hell of a lot of cranking) it starts, it starts really roughly, blowing smoke, and no guts in it at all til it uses all the fuel (obviously floods)
It turned out to be some nitwit has piggybacked a wire off the ECU, and the wire had something to do with engine heat (or something like that), and it was shorting out, hence no spark. Just food for thought

check the rotor button, might'd be 'home' also try replacing the hall sensor

had the same problem on my EL, replace the coil, drove me nuts cos like you said starts ok when cold, but when hot it goes no way buddy... I think probable cause is resistance goes high when hot and doesnt have enough power when you are trying to crank the motor over due to power drain.
I replaced my coil due to this problem and hasnt had a problem since... only problem is they are a bugga to get too... prepare for massive amounts of swearing!

try chucking another relay in the starter relay position. My old bunky EA had the same problem and it was the relay.

had the exact same problem with my XF, it'd crank its heart out, but wouldnt fire, swapped the TFI module, no help, swapped the dizzy and fired straight away
turned out to be a FUBAR hall effect module inside the dizzy

OK,
Just put a new module on and new hall sensor. It started fine, but thats due to the motor being stone cold, drove for 20 mins around the block, got home, turned it off, turned key and it fired again... then idled for 20secs and died without warning, wont start again. So, tomorow I'll go buy a new coil ( this coil is 3000kay/9months old ) and see if it'll start when hot. Where's the starter relay? I'll grab a new one and try it too. |

starter relay shouldnt effect it as it only is used when you crank the motor and that seems to be working fine.....
but starter relay is one closest to the fuse panel under the bonnet (bank of 4 relays) on a ef/el pretty sure same on ea (relay closest to water res)

Just put a new coil on it. MSD coil, I mounted it on the shock tower with new lead to dizzy, cut the old coils injector type plug off and solder longer wires to reach the new coil.
It started fine, idled until it got to 80 deg and ran for a bit then died... wont start again. So, it has brand new battery,coil,coil lead, TFI module and not very old rotor,cap,leads, rebuilt dizzy... what can I change now?? One thing I notoiced, on the wires that plug into the standard coil, the earth wire goes into a little blue box and out to the coil, what is this thing? And should I use it with the MSD coil. |

Im now 99% sure its fixed. I found an earth wire that looks like it goes to orcomes from the module/coil wiring that was connected by its last strand... soldered it up and it started first pop and is now behaving itself.
Lucky I bought all those new parts haha... stupid wire |
