Car will no longer start :(

[Asacei]

Hi,

Ok quick summary....car was running albeit with a few idle issues, changed gearbox (due to other problems not because I thought it would fix the idle ) .......now car turns over fine but won’t fire up

The problem appears to be spark related.

The car has new plugs, new rotor arm, new distributor cap.

If I pull one of the plug leads and using an old spark plug check for a spark I seem to be getting an odd, fairly week spark, just once when the engine first turns over but then no further sparks. But this is a fairly hit or miss occurrence with there often being no sparks generated at all.

I am struggling to work out why it would suddenly start doing this when it was previously starting no problem at all.

So most likely causes?

Coil pack, they can go anytime even if it started fine ten minutes beforehand I found that out lol, is the rev counter bouncing when u turn it over

Yep, sounds like the coilpack. Happened on my old lude, dead easy to replace and are about £25 off ebay.

Cant say I noticed the rev counter bouncing. Would the coil pack going still give the odd spark? I thought it tended to give nothing at all if it had given up?

Could also be the dizzy cap or rotor.

Also the dizzys are really sensative, if you check for a spark and the plug is not properly earthed, this can blow the dizzy too. The safest way is to connect a jump lead to the negative of the battery and clamp the plug with the other end.

Also worth checking that the earth to the thermostat housing has been put back properly, this will prevent the car starting too and it's likely affected if you have swapped the gearbox.

Dizzy cap and rotor are both new, so think its unlikly to be them.

Spark plug used for checking for spark was earthed well to the header and the block is well earthed so should be ok (battery is in the boot so jump leads wont reach the negative terminal)

Good point on the earths Vtecmec, they got a quick check over but worth a double check

thanks

There's probably a few symptoms why it won't start my car would turn over and give the occasional hint it was going to fire up but eventually it just wouldn't so I replaced the coil and boom fired up on first turn of the key, easy enough to change the coil in the dizzy

Thanks GJMHONDA2012, I have ordered a replacement - hopefully will be up and running again next week
