Do I understand you correctly ?


Are you saying the coil is sparking with the ignition and the engine is stopped ?.

Can you hear the fuel pump running continuously in the SAME circumstances ?

If so, sounds like a crank sensor issue. (open circuit).
There is a test for this if you have a multimeter.

glancy2081

yes u are correct simon u understand no fuel pump either not cranking it over but ignition on coil sparking and no fuel pump buzz

Does it spark once, a few times or is it continuous ?

glancy2081

continuous this could be a phase test to see who is qualified to be a techie on here

Techie, dont start that "war" again

Was the car running fine before this or did you have it in pieces ?

SOme possible problems...

The ecu is missing its earth connnection (inlet manifiold)

The crank sensor is open circuit.
Pins 3 and 4 on the ecu loom connector should read 600 to 1200 ohms
when the ecu is removed.
Pins 3 and 4 are on the longest row of pins counting from the loom entry end.

The ignition module has lost its earth which is on the inner wing next to the coil.

Obviously, without seeing it myself it could be anything but these are
most likely.

the imobiliser has just been replaced the standard winpac one as it was faulty, tried putting jump lead from battery to inlet manifold and batery to body.started and run for a couple of seconds and cut out then would not start, would that also explain no fuel pump simon going to replace crank sensor thanks u may qualify for a teckie in my opinion lol

Dont discount the imobiliser may be fooking things up for you.

Most likely by the sound of it.

glancy2081

its another unit which is known to work ?

glancy2081

would imobiliser also cause coil problem

Did it run ok before the imobiliser issues ?

I wouldnt trust those WIPAC units working or not.

It really sounds like thats the issue to me !

You need a pro to look at it or its going to be a ball ache to sort out.

glancy2081

the pros all seem to be affraid of coming to look at it was fine then one day would just not start then 2 weeks sitting in garage it was fine a thought imobiliser cut spark to though it sparks when cranking to though

Usually on immobilisers, they isolate 3 to 4 circuits.

Usually fuel pump, ecu power crank/phase signals.

If any of this is faulty your car will not run and may exhibit problems
like you are getting.


Where do you live ?

glancy2081

oh well looks like a need to find somone to remove it then do the instructions that were doing the rounds work simon u know ?

Never seen any removal instructions myself.

I did one 4 or 5 years ago but cant remember details
