the car then died out and would not start i have changed the battery new plugs new ht leads and still nothing

i need help big time to get my car started any ideas........?

Has it got sparks?

[Raas_s12]

yes i have also changed the spark plugs.......i am a bit lost now.

do a compression check as the 5th injector might have burnt out the valves as usually they are more hassle then they are worth.

[Raas_s12]

ok will do is there any thing else i can do jus to have a list of things because the car is in manchester and im in leicester and i will be going there very soon to do the work.

the 5th injectors are usually on a pressure switch, se nissan used a metro oil pressure switch that came on far to early, 5psi if i remember correctly, this would probably bore wash.

the 5th injectors can supply to much fuel, this will wash the protective lair of oil off of the bore, leaving metal to metal, you need to get it running and then set up on a rolling road and check the afr ratio.

its probs either spark, fuel or compression.
As you have spark then its one of the other two.

It could be a faulty fuel pump,
faulty imobiliser to pump if ones been put in,
faulty fuel pressure regulator
severe boost leak from an intake pipe

thanks a lot for the info guys....i jus wanna say that i have fuel and spark so now its going down to compression........if there is loss of compression what can i do next?
