NA6 stopped dead. Electrical issues.

Could also be embarrassment - maybe Patchy is tired of running around half naked and is hiding till you come up with a nice red coat

could well be bigdog

OK. No action from the pump when ignition gets turned on. No hissing or humming
lowmiata I'm not entirely sure what you ment with

" your hand on the rocker under the door and feel the car hum when the pump runs "

turned it over a few times......spark plug is as dry as The Simpson Desert.

got Spark
no fuel
try to conserve the battery now.

fuel filter probably needs to be changed anyway.......hasn't been changed in ages.

Whats the most logoical way to check from here.

[StanTheMan]

Could it be the timing belt.... or is that a stupid guess?

not stupid but very unlikely....timing belt was changed with the engine swap 30k km ago.

[kitkat]

hmm fuel pressure.... dissconnect the fuel hose in the engine bay and crank her over for half a second... if your lucky she spurt out some petrol indicating fuel pressure.

Prob not the best way to check but a certain way.

(This will eliminate or not the fuel pump also)

[mickfred]

air filter blocked or afm stuck closed?

[StanTheMan]

didn't check that mick......but will do tomorrow night regardless.

Miata.net says you can strap F/P and GND at the diagnostics connector (similar to your fan) and with the key in the on position the fuel pump should be running.
That would save some battery as you aren't cranking the engine at the same time and will be able to hear the fuel pump.
If it's an in tank fuel pump, it will be fairly easy to replace.
(Sorry I haven't looked for it yet)

[StanTheMan]

sweet...i'll try that tomorrow.Thanks ampz

Time for an NB8B eh Stefan???

[StanTheMan]

If anything....yes it would be an SE

but that is really no being realistic.

If you have fuel and power check the main ignition relay - about $35 from Mazda for the NB one. I carry a spare for mine after Dave had two fail...

I've had 3 of these go, $25 from a wrecker or $110 from newells!!

It's the big green relay in the underbonnet fose box. Will probably have a fried terminal.

It powers the fuel pump, fuel sender unit (have you noticed your gauge acting strangely?) and the injectors. Without it - no fuel gets to the engine.

[StanTheMan]

wow caff if it turns out to be the ignition relay.....its the first time i've had to replace it.
i've had the car for 10years.....
guage has been normal....or i haven't noticed anything strange.....

Thanks Caff & Bigdog.

All you need to do is SKI Stefan. That's Spending the Kids Inheritance.

I hope it works out to be something cheap and simple!

Jeebus Caff! Newells certainly win at that rate ! As Biggus D said, I bought 2 of them from Penruff Maz for $35 each... one sitting in the glovebox for 'ron.
I wouldn't expect this to be STM's problem - wouldn't the relays etc. be different on the little red rocket?

Steffan - it's pretty unlikely to be a fuel filter - as they block gradually, and normally you feel this as missing or temporary cut-out under load at higher revs. Idle and lower revs usually function OK. Also no point checking timing belt if you don't have any fuel getting there.

Cheers and good luck,
Dave
