my 2.0 ultima wont start

Driving along very nicely, then it cut out, try to start it, fires up then cuts out instantly, towed it home had a fiddle,
cant get it to run at all, turns over and some times fires up then dies?
i checked for a spark and seems to be sparking, checked for fuel, seems to be fuel there via the bleed valve?
anyone got any ideas?

i checked the coil packs for a spark on all 4 seems to be sparking on all, checked the spark plugs. they seem ok
check the fuel rail for power all working
when i unplug the fuel rail on 2 / 4 ? it makes no diff to how the car runs?
plus when the car gets hot it wont start at all

A suggestion:
Fuel Injector Relay sticking. Get it out, and tap it. Then try again. The contacts sometimes stick together, and can cause intermittant start failure problems.
Only way is a new relay. We had this on another car, took ages to sus it out, and it can be very worrying driving along and suddenly the power just goes and you are not running anymore. Especially if you have 40 tons of lorry behind you!! 
Worth checking anyway. It's relay No. 17

hi there
i'd give all the wiring to the coil pack a good look over. could well be breaking up. also the coil packs themselves could be suspect. they're wasted spark ones hence the 'spark' moving between the leads.

hi there
have you taken the 'fat short' leads off? have a look at the connections for oxidisation. it's also possible that the spark plugs have went 'off'. this can happen very quickly with platinum ones. try swapping them around.
btw, don't run it too much as petrol will be getting to the cat and ruining it.

yes i tested a spare spark plug directly into the top of both the coil packs nothing, some time there is a VERY faint spark?
only the spark plugs that sit under the coil packs seem to be working

hi there
i'd say it was the packs then. can you swap someone for a known good one to check?
shouldn't be too expensive in a scrappy.

Hi. sounds very much like the loom wiring to me, unlikely both packs would go at once. Check the part of the loom where it enters the recess at the back of the engine where the coilpacks are, mine fell to bits under the outer loom insulation. Sometimes it's gone bad right down to the fuel rail.
Regards, Bruce.

If the car won't start when it's hot, then it could be the fuel rail pressure regulator at fault....I had the same problem a few months back

Dont think it was just the coil packs alone, ive cleaned all the plugs, wiring, injectors, inlet manifold so on, its never ran so sweat, i gave it a full service, flushed the engine out, water filters, pollen filters so on.
like a new car now
it was lucky, as i was ready for taking it to the scrap yard.
