Sounds like a couple of plug leads have gone on the wrong plugs.

Likely culprit..........crank sensor.
Also check wiring to cam sensor (94) and MAF connection (74)

51M0N · « **Reply #15 on:** 09 July 2011, 20:48:44 »

where would that be on my 3.0? is it at the front of the passenger side bank?

51M0N · « **Reply #17 on:** 09 July 2011, 20:54:48 »

checked crank sensor where it plugs in at the rear of the engine. its plugged in, ive not been underneath it so it cant be that, i wonder perhaps the wiring bridge over the passenger side bank if ive knackered a wire?

Not doubting you but are you 100% sure, also are the leads secure in the dis?

yep, i never took the leads of the coil, just off the plugs.

checked the coil anyway in case i pulled one off but even if one was off should still start?

51M0N · « **Reply #22 on:** 10 July 2011, 09:43:42 »

Going to take everything off again and check for any broken wires etc

i looked at the coil location on this photo http://images.omegaowners.com/images/guides/v6_engine_pics/IMG_0025.jpg mine is the other way round, as in the plug is at the opposite end and its mounted on its side.

51M0N · « **Reply #30 on:** 10 July 2011, 12:18:14 »

managed to solve the problem I think,

the no6 plug lead in a word is f****d hence the misfire the first time.

the reason it wouldnt start the second time is because 2 and 4 lead were the wrong way round as i made a mistake looking at the key for a different coil when mine is the early one and the other way round.

thanks to Steve (tigers gonads) for coming round, nice guy.

Going to buy a new set of leads tomorrow and hopefully all will be well.....

Vacuum leak ?

tigers_gonads · « **Reply #38 on:** 11 July 2011, 18:46:46 »

Right, i've got simon on the phone now

He has just disconected the maf and it starts and runs but hunts between 500 and 2000 revs :-/

Any idea's ?

RobG · « **Reply #39 on:** 11 July 2011, 18:49:38 »

As per Albs, vac leak, & sounds like knackered MAF. Carb cleaner around all the vac connections, listen for changes in the engine note

RobG · « **Reply #40 on:** 11 July 2011, 18:50:53 »

Can you swap your MAF over see what happens then. If it`s the MAF I`ve got one here for a 3.0ltr

tigers_gonads · « **Reply #41 on:** 11 July 2011, 18:56:38 »

At one point, one of the ht leads fell apart.

This has now been replaced but could it have caused a spike somewhere and breaked something up ?

Thought about the carb cleaner but the engines hunting that much ( with the maf disconected ) that you couldn't tell anyway

It won't run without the maf plug out.
Would a vac pipe cause it to die but by disconecting the maf, it runs :-/

Are you near to him to try your MAF to eliminate whether that`s the cause

I have a 3.0 MAF or 3 here...although does sound a lot like there is an air leak...a bad one could be caused by the plenum not having been sat back in place properly when putting it back together...or an o ring jamming it slightly open...

tigers_gonads · « **Reply #47 on:** 11 July 2011, 19:06:44 »

Simon, answer your phone

TheBoy · « **Reply #48 on:** 11 July 2011, 19:09:26 »

Is the 19 still there? This often throws a MAF code.

I would be looking at resolving the 19 first

tigers_gonads · « **Reply #49 on:** 11 July 2011, 19:15:18 »

The engine is a very early one 1995

The coil pack and maf have the square plug

Has anybody got any of these left ?

51M0N · « **Reply #50 on:** 11 July 2011, 19:21:20 »

if i let it run for a bit with the maf off the idling levels out at a lumpy 800rpm took the maf off now cant see any physical damage

tigers_gonads · « **Reply #51 on:** 11 July 2011, 19:24:14 »

Sounds like your MAF is breaked

Stick a wanted advert in the part section

Make sure it says " Square Plug "

51M0N · « **Reply #52 on:** 11 July 2011, 19:59:01 »
