ecu woes!!

[garymar1983]

hi guys need a favour of someone, had my clio track car out last weekend, got a few hours done then came in for some grub, switched car off, as ya would.
When i went back to it it would not start, just turns over. no fuel no spark.

this is the cars 2nd ecu. which i bought from a member here.
the original ecu i took out and put a chip in it, then car would not run, same symtoms, no fuel or spark.mayb i broke it??!!! not sure..
thats when i got another bought standard ecu, plugged it in and hey presto, until last week half way throgh our session :( :oops:

can i send someone the ecus to plug into there cars see if it is problem with ecus or mayb it is something else??

any help would be great

could be the sensor on the gearbox/flywheel..tdc sensor

[garymar1983]

hmm i suppose ill have to investigate that. cheers, would that cause the fuelig to stop too?
i thought crank sensor would just cut the spark????

[MAXIBOY]

iirc its cuts both but not 100% sure

bad earths/broken earth strap...

...Loose connector/typical French petulance...

If you turn the ignition on, but not far enough to turn it over, does the fuel pump run as normal? OR do yo get a click click click from the injectors?

[garymar1983]

Earths fine I put new one on it!

Not sure about fuel pump noise fairly sure no noise I've never noticed injectors clicking ill check and get back to you. What's your angle???

[kj16v]

In normal operation the pump runs for a few seconds to build pressure and then stops.

If you have totally duff chip then the injectors will make an unmissable clicking sound.
