z 1000h again

[hoood469]

so the H has decided to throw a wobbly again !!

It runs then it doesn't then it runs then it doesn't !

Anyway after stripping everything down rewiring the injection loom changing everything pump, regulator, relay cleaning the injectors you name it I've done it, to no avail. so on day 4 I for got to attach the temp sensor wire and it ran !! attach it, it doesn't replaced the sensor with a good one same thing doesn't like it
it runs crisp probably better than ever with it not connected so is it the brain ? I would have thought it wouldn't run with it connected
also why would it be intermittent it ran last week for a whole day with it connected all of the loom has been replaced so no faulty joints etc
Anybody got any ideas ?

,mmmmmm errrrrr ..lol ,they are strange beasts these H's ,mine wouldn't run without it connected.So ive no idea why yours is doing that
but enjoy

[hoood469]

yeah I know Ollie, logic says it shouldn't run without a signal,
took it for a ride today wouldn't pull missing like a pig, further investigation needed would prefer a H over a MKII but the carbs are on the bench !!

[ollie]

could well be the ecu ,might be worthwhile getting it checked by a ecu specialist .
carbs are on my bench too

the most common problem iv'e found with all poor running F.I. models is the fuel return valve back into the tank sticking not opening fully....

[ollie]

ahh yes i agree ,good point there

[hoood469]
