engine flat spots,then goes!

[stag76]

hi ads,back at car today,just to move it out of way.

struggle to start it,when she did start,she very feathery and more peddle pushing to get her to run.

after a minute of this she evened out. as before she reved cleanly in nutral,no miss fires,nothing,sweet engine.

went for a run,and as b4 if you drive her real gentle and bring it up the revs very slowly she grand,but drive normal,and she acts as if she running out of petrol,and if you shak it down the road,as in left right she will almost stall.

its fuel delivery,a duff pump,or as mentioned the fuel regulator.


il keep you posted,but il get a lend of a pump and a few bits,that i know work.


thanks jay

Throttle position sensor maybe.Did you disconnect the lambda sensor to rule it out?

[stag76]

hi sideways,ok ill try what you saw when at car next,will she run with lamda sensor off?

keep you posted thanks jay

[pjmazda]

Curious, did ya ever get this sorted?

[sidewaysreilly]

yes it should do.

[MX5Spares]

J,I will give you a lend of fuel pump if thats going to cure it !!! Sounds like that to me ,like intermittent fault or loose pump/relay wires .Try wiring pump up directly to check only.Me fingers are getting shorter typing replies to ye. Fix the fe.king thing.

[stag76]

she is fixed

god but what a job,you mention it,i did it.

it was a wiring problem,or more like a ass who created a wiring problem,some git had used the earth of the pump as a earth for a fog light!!

the bulb was loose in the holder in the light,so when it got a bump or moved it would mess up the pump.

my irlfriend was following me one day and told me the fog light was glowing and going on and off,so as it flickered the pump would go on and off

they hadnt even used insulating tape it was that bad a job!

she goes very well,and starts first turn of the key.

mad what people do to there cars.

so thats the story so far

[sidewaysreilly]

Well done, thought as much.

[stag76]

hi sideways,so you knew my pump was wired into my fog light i spent well over 10hrs on the damed thing,and they spliced in where i couldnt see it,there was even some made switch affair also .


all sorted now,never again,she was close to have been broken for parts.


count me in on the track day in louth.

Some asshole owners do stupid'and dangerous things but glad to hear it is sorted.

[Steve]

jebus... glad to hear its fixed, fair play for sticking with it.

[sidewaysreilly]

yes , i said to check all your earths. Most common fault .

[franksm]

Nice work !

Sounds like someone badly wired a cutoff switch. What a mess...

[stag76]

thanks lads.

yes they had just piered back a pease of the insulation and wraped there wire round it,with no tape or proper connecter

and to wire it then through a fog light???


all wires were speaker wiring,so alot going on as there was 4 aftermarket speakers in the car,all the wires the same colour .

sorted now,and mite even be sold,watch this space.

have 5 mx5,and this 1 was forced onto me by robert ,bargain price .

thanks jay
