Please help, me

I have a problem with my 4x4 saff, I was driving the car and it was fine, then it suddenly cut out as I was changing down the gears, I bump started it, as i was moving and it ran for about 30 secs, then cut out again.
Now when I turn the key to start it, it fires and runs for about 2 seconds, then cuts out.
Any ideas what the problem is as I need the car for Stratford tomorrow.

P.S The car has not been started for three weeks, and it had a flat battery, is this anything to do with it?

 

I'm not being funny here, but does it defo have fuel in it?

Neil.

 

your batt light on dim too

 

YES, I may be a bird, but I aint silly!!!!!!!!!!!!!!!!!!!!!!!!!!!


The fuel pump primes, getting sparks, all engine timing is correct etc, everything that should be there is there, there are no obvious faults.

 

No it goes off when you crank it.

I charged the battery all night last night.

 

though it may be the fuel pump.

 

Aye - sounds like fuel more than owt else eh?

Neil.

 

Its priming, so it cant be.

This is doing my head in!!!!!

 

Time for a compression test then.

 

You say you need the car for stratford tomorrow? whats going on in stratford then?

P.s sorry its not a reply to your problem!

 

The engine is fine , just had fresh rebuild and been mapped at motorsport developments (stu is a top bloke)

 

Run what you brung at long marston airfield aka shakespear county raceway

 

how long was it deaad for your alarm could be a bit fookd and cuting out the car

 

dodgy map sensor?

mine did the same would run for a bit, badly and then die

 

It was flat for a max of 5 hours, and I charged it straight away, it was fine earlier, as I have done about 15 miles in it today before this problem started

 

has it got one of the silly cut off switches in the boot like on my xr keeps trippin out all the time car will start but then cut out when i rev it

 

No that has been checked already.

This is so anoying , just when you think your car is complete, something else goes wrong with it, the joys of cosworths

 

to fire and die does really sound fuel related after it conks are you getting pressure at the fuel rail ?

 

The fuel pump is priming, how can the pressure be checked?

 

Wicked, i live like 5mins from the venue, i knew there was an event last weekend but not this weekend aswell

 

check the fuel inlet

 

could try wiring the fuel pump up permanently.

Sounds as though the fuel pump is working when you crank the engine then cutting out when you release the key.

Get a wire in the live at the pump end,unplug the live wire,shove the wire in and plug the plug back in.

Wire up to a live,either battery or the rear light, depending on the lengh of wire,must turn on the lights though to have a live.

 

Map Sensor?? My Esc Cos would take ages to start and when it did you tried putting ya foot on the peddal and it just died, which turned out to be MAP sensor! Changed it for a new one and all was fine

 

i also blew a map sensor on a 4x4 a few yrs back done the same, mind you the hose on the compressor housein split and it prob hit 40 psi or somin pmsl she popped then instantly dies, shat me pants i did

 

Im going mad

Nothing seems to be making it work

 

Aaaaahhhhh Cossies, Definately sounds Fuel related

 

what about speaking to stu ( or kenny ), he might beable to help ya

 

Very helpful fellas.

 

Did you dis-connect the ECU before charging the battery or use a "spike "protector when you charged it ? Im sure you will be more lucky than me but ....if you jump or charge these things with the ecu connected it can , and Does fry the chips , ive had this before with a huge misfire after re-charging a battery on a racecar and found a Drop out on the chip that needed replacing to cure it .!
sure its only a blocked filter or something stupid tho .

 

all new cars cant be jump started as that DEFFO frys the ecu,,,,,,,,, ask the sales manager at lookers nissan when i fryed the ecu jump starting the 350z with a jump pack


he will remember as the reason the car wouldnt start was i wasnt dipping the clutch

but i said call it learning, we now know to let the batt charge for a while before jumping it

 

no I didnt disconect the ecu, i did not know it cause cause a problem

 

Crank sensor possibly?
