Relays involved in Engine Start

Post by malcster »

Hi Folks,,

Having a few issues with the car not starting, which I think may be related to a relay.

I left the car for a week, and it wouldn’t start when I returned.

It would crank, and then the engine would catch as if starting, fire once, then die immediately (as if there were no fuel to keep it running :-k ).

All ignition components are relatively new (circa 6 months) Coil, Igniter, Cap, arm, leads, plugs.

So I'm guessing its relay related?
Would this sound probable? :?

Close Circuit, EFI, and Main Ignition in particular - all located in the engine bay fuse box as far as I can tell.

Are these relays all the same throughout the revs, and models?
N/A and Turbo etc?

If so, I'll go grab a couple from a scrappies and see if it makes any difference... \:D/

Cheers,

Malc

Check to see if the arm/flap in the AFM is siezed.

How do I go about doing this?
Is it just a case of taking my HKS Cone filter off the AFM and looking inside?

How do I go about lubricating it if it has siezed?

Yep, whip the air filter off and poke the AFM flap with screw driver or something,

If the ingition is on you should be able to here the fuel pump switch on.
We ALL make mistakes !!! :)
