98 4.2 replaced battery now it wont start

[bigdaveh]

hi all

can anybody give me some advice?
i have a 98 4.2 cerbera
the battery was not holding a charge
so i replaced it today
it fired up 1st turn so i was happy ( job done )
it ran for about 5 mins then it cut out now it wont fire atall ( gutted )

there are a few factors that may be relavent

1. the new battery turns the car over much much faster than the old one ( though im sure that is a good thing )

2. i removed the engine bay cover under the windscreen
and it was off a few days ( and yes it rained )
so i thought it may be the coil packs
thought it is not even trying to misfire

3. i have recently replaced the oil pressure sender switch
iit had been running fine after this ~( could i have dislodged somthing? )

4. i have check the big fuse its fine

5. has my car got a emergency cut off switch anywhere?
though there does seem to be fuel at the injectors

any advice would be greatfully received

thanks in advance Dave

Is it turning over, or just dead?

Did u hold button down on key fob when replacing the final battery lead as alarm imobiliser needs to be reset.

5. has my car got a emergency cut off switch anywhere?

On top of the tank in the boot.

hi
thanks for the info
it is not the emergency cut off but thanks for the location

i have just had a plug out and found that there is plenty of fuel getting in but no spark atall
if it was the coil packs would it not try to misfire
it just seems strange that it went from running fine to not firing atall

is it possible that my new more powerful battery has scrambled the ecu somehow?

anyway i will keep trying
anymore thoughts would be great

hi all

well i got it started
the coil pack fuse was blown it started the stoped again blwowing the new fues

is it possible that the new battery could cause it to blow the coil fuse?

....or water. You said the coil packs may have got wet.

hi

yes thats very possible ( and it makes sense )
is there any way i can check to see if they have got wet?
i cant see any moisture looking down
is the only way to find by replacing them??

again thanks for the advice

Once you've got the engine running thy will dry out .
When they get old the coil packs can get little cracks in them, so you probably wont be able to see any water. Use a Hairdryer to dry them out, just position it in the right place and leave it running for an hour before trying again (or if your anything like me every 5 minutes).
It's a bit strange that it did run for 5 minutes before stopping! You sure it hasn't run out of petrol? Go on, give us a laugh and tell us thats all it was.

hi

lol
no it hasnt ran out of fuel
if i can get some new coil packs on a saturday
i am going to replace them i have seen from some of the other postings on this site that they are the same as citreon and pegeuot
so should be on the shelf

hopefully a few scratches on my hands and all will be fixed
atleast i hope so as i cant stand it when my baby wont perform lol

hi all

thanks for all the advice
i have sorted it
when i replaced the oil pressure switch under the coil pack
i traped the wire going to that coil under the fuel line so it was shorting on the block
it starts and runs now however its a bit lumpy
so i am going to replace the coil packs anyway (probably not been done for ages

thanks Dave
