Dead JA

[JD_Stazza_Brendan]

Bit of a long shot but im grasping at straws.

On way home car suddenly started shuddering, like a plug lead had come off. Couldnt pull over on the road i was on and had to stop at a set of lights where the car died and would not start again.

I pushed the car off the road and started looking for obvious problems.
My JA has Sonata MPI with a LINK V4 computer
*All plug leads are connected right
*Fuel pump still works (can hear pumping away in back like it always has)
*Changed plugs
*All 4 plugs have good spark
*All earths checked
*Wire connections checked including injectors,ecu
*Timing checked (all lines up perfectly)
*Can smell fuel after trying to start it
*Motor turns over fine just wont start
*Car was running perfect before this
*Battery connection good
*Battery voltage great
*Tacho bounces when trying to start car
*Vacuum lines fine, even one going to MAP sensor on ECU
*Havnt done compression test

Any ideas??

Snapped cambelt?

[JD_Stazza_Brendan]

Nope, its all good and got tension

[bigd]

Have you had the cover off and had a look at the whole belt?
Does it try and fire or does it just turn over and over?
What were you doing before it started playing up?

[JD_Stazza_Brendan]

Took cover off timing belt, its fine.

Started the car up, started driving home from mates house. about 500m down road it starts spluttering.

[bigd]

If it just plain doesn't start it has to be fuel (which you said is fine), spark (which you also said is fine) or compression. Can you check compression of each cylinder?

[Starion VR4]

mmmm, check yr ignitor & the earth to it. :beer :beer

[OLD FART]

Had a similar problem donkeys years ago & it turned out to be a blocked fuel filter .
Suggest you disconnect line before rail & see if the flow is a stream or spits & farts like mine did
Hope this helps

[JD_Stazza_Brendan]

How would i go abouts finding the Ignitor..Is there a way i can trace it back from the Coil?
Could it be built into ECU?

The fuel filter is a clear one that sits in the engine bay, Looks like its full of fuel. Ill swap it over anyway.

[Starion_Turbo]

when driving along did you loose all power and notice cars speed dropping and running like 2.5 / 4 cylinders stalled when u'd stopped?

You might have had the head gasket let go between 2 cylinders, check all 4 for compression and you may find that 2 ajoining cylinders have little to no compression.

I had this happen a few years back.

[JD_Stazza_Brendan]

Thats the other thing ive got to check. Ive got a compression gauge at home somewhere just got to find it.

But what you described is what happend. Felt like it was on 3 or less cylinders. then when i had to stop at the lights it died.

If i took off the rocker cover i should see water in the head shouldnt I, or is this not always the case?

Umm, in a word, no! Oil yes, water no...

[JD_Stazza_Brendan]

Sorry, meant to say, if the headgasket was stuffed would i see some water in the head..

Or can the headgasket be stuffed and not show signs of water in the head

[WidebodyWoody]

I think if the head gasket is stuffed, you don't necessarily see water in the engine. That is mainly from cracked heads. But I have not had a gasket gone on me before, so I wouldn't know 100%. It is probably possible.

Hey Brendan, This has happened with this car b4 and it was the
igniter




just in front of the left/front strut there is this black box
and a long time ago that igniter sh-t itself and it may
have done it again, check that the WHITE wire going to the
igniter isnt broken (AT THE IGNITER)
When I blow my last head gasket it was between cylinders
and NO there wont be Water or oil swapping going on.

Cheers:Phil.
