and the sump,flywheel,water rail etc is changed over.

at least it's not raining :D

just having a coffee, then get the engine in the escort.

anyone intrested in a kooltina rolling shell?

it won't start on the starter motor!!!

the crank position senser is not registering rotation.....diffrent car, diffrent loom, diffrent starter motor, yet the same problem as kooltina had last week. hmmmm. maybe the ecu? can't see it being the ecu myself as when kooltina was bumped, she ran fine.

bump the escort tomorrow, if it starts i think i can count out dodgy ecu.

something really simple...........but i don't know what!!!

when the starter is cranking, the led in the ecu stays red.(it goes green when the ecu gets signal from the cps)

when you take your finger off the start button, the engine rolls to a halt, usually 1 or 2 rotations and the ecu led goes green and when the laptop is plugged in, the live adjustments window shows the rpm, but has XXX as rpm when the starter is cranking. XXX is displayed when there is no signal from the cps.

i totally bypassed the ignition and took a wire from the battery to the starter, and took a feed for the solenoid from this cable, spun the engine like this, but still the ecu does not recognise rotation.

if no rotation is recognised, no spark and fuel signal is sent, so it doesn't start. i span it over with a fully charged battery and it used to fire from a much lower rpm. but starts straight away when bumped!

i cleaned all the earths incase it was this, but no difference. the cps has been changed and must be doing it's job as it will run when bumped.

could the battery spin the engine over at normal rpm, yet not leave enough volts for the ecu?

Have you checked the live is at the ecu while cranking. Not just a normal ignition live? Power the ecu direct from battery live as a test. Possible the starter is drawing to much current and shutting ecu down temporarily.

does interference "start"?

the car started last week with the other engine in. i will replace the cps wire with shielded earthed wire, and swap the cps wires over, as dave at emerald suggested. :(

it runs!!!! :mrgreen:

all this shyte and all i had to do was change the cps wires over!!!

you learn something everyday, strange how it ran for the last 3 yrs with the wires the wrong way round :huh:

good old rave talker :thumbsup:
