Auto Electrician Please Help!

Hi Guys

Can anyone recommend a decent auto electrician in the east mids area?

Got a starting problem on my Elise S2 2001 which I have now hit a brick wall on. I have bypassed the meta immob, replaced the multi function relay unit, checked all the fusses and earths, changed batterys in remote, it has a new car battery. When I turn the key to start the only thing I hear is one of the relays in MFRU clicking. Fuel pump not priming, I started the starter motor manually with a screwdriver, this in turns causes fuel to flow and the engine and it fires briefly, then stalls.  

Anybody have anymore ideas?

Cheers

Start at the beginning. There is a permanent 12v supply on the large connections on the starter motor. The coil of the starter motor has a small spade connector on. This is what shuts the contacts to allow the starter motor to work.

 

Is the spade connection on correctly and in good condition? Welcome to MLOC BTW   :)

Thanks for reply guys

Martin:

Yes I have removed spade connector and checked it, its good condition, this is how I manually started it by disconnecting the spade connector, put ignition on and bridged that connector with a screwdriver to the permanant 12v feed, it fires briefly then concks out.

Phil:

Fuel pump won't prime on ignition setting 2, but when I bridged the starter motor I disconected the fuel line before the fuel filter, and fuel is pumping through quickly. Looking back that could have been dangerous with the sparks from the screwdriver.. LOL

You need a decent multimeter then. Check there is not 12 vdc on the spade then? you will need to put the black lead on a good earth. Work your way back through the circuit from there. I dont have a circuit diagram to hand at the moment.

Thanks Martin, bought a new clarke multimeter last week from machine mart, as old one was knackered, and already did that, there should be power there when cranking but zero. Earths all good too, getting the same reading when checking direct battery voltage and checking battery positive to engine earths. I bought a used MRFU to and was the same, I have taken apart the MRFU and checked the four relays with a 9v battery, they all open. The car has been off the road in my garage with engine out for the last five years (don't ask!!) Everything was working fine before, car has only covered 21k and is in top shape.

Thanks for the video however I have an early S2 sports tourer which used the Meta alarm and immob system, as did the 340r.

From around feb 2002 onwards the cobra alarm/immob was introduced. I only have the one button on my remote, which is incorporated in the key.
