have a look at your engine loom where the crank sensor plug connects - see if either one of the wires is damaged, or if one of the terminals has pushed out of the plug housing

Is the new CPS securely connected and correctly adjusted? It may not have been secured when it was installed. The gap between the sensor and the teeth on the crank pulley should be 0.6 - 1.0 mm.

Mine died (spectactularly) a while ago because the king lead decided it was time to end its relationship with the dizzy cap. So I'd suggest they're all secure too.

Does the pump prime first thing in the day ?

rite lads ive done the following checks

fuel pump primes wen ignit turnd on
the cps sensor is gapped to 1.0mm and all 4 lugs are intac
done a quick wiggle test of engine loom while trying to turn it over and still no spark.

bloody eletrics and sensors

Try and get a hold of an ignition amp to try, i had same symtoms as you and a new (second hand) amp cured it.

tabetha

The fact that it primes the pump tells you it is getting cps signal so that can be ruled out.

Have you checked for a spark from the king lead? If you get a spark there, your ignition amp is probably OK.

could be a faulty coil, or try swapping ECU with a friends

i havnt yet checked to see if there is a spark from the king lead as none of the other leads wud spark. wots the chances of a grp a coil failing to work?

i wud like to swap the ecu to rule tht out but none of my m8s have a cossie cos they know the hassle i get wiv mine lol goin to ave a full day on it saturday to see if i can get it started.

wud the tps sensor stop the car frm starting at all?

mechanic28

would not try swapping ecu just yet as u might fry it lol!is your phase sensor ok,gap,condition of wiring?altohugh not sure if that would stop her from starting??is your cam timing all ok?

check to see if there is a spark from the king lead, if there isn't, its most likely your coil is fucked. If there is, then only your dizzy can be fucked.

nugnah

Andy, i think i have a spare ECU you could borrow, i'm in Caerphilly South Wales, and could post it to you to try if you want. I will defo check in my toolbox for one.

you checked the fuse on the engine loom under the dash? mine got knocked by a mate in the middle of nowhere and took ages to find out.

but if you keep cranking over, when you find the fault, change the oil and filter, because the unburnt fuel might be thinnning down the oil and it will rattle your engine

jst finkin now if theres power to the coil but not not sparking,cud it be the king lead fukd? i have the blue magnecor leads and wud a 4x4 ignition amp wrk as i ave jst found 1?

ive had the ecu out and tht all looks fine but thanks for the offer nugnah

biggiejody.ive checkd the relays and fuse's every wer and they are ok

fink i'll jst ave to spend sum cash on a new loom,l8 ecu and sum goodies from motorsport develoments defo gonna go for wasted spark set up

Reno5GTT

Yeah they should both work the same, my 2wd one worked in my mates 4x4 anyway.
