Flooded engine wont start. running out of ideas

[Marky]

It worked before

You changed something

Now it doesnt work

My suggestion would be just put it back the way you found it

[Guest]

Just throwing this out there as I have no idea and I would highly doubt it but could the ecu learn the smaller injectors to a degree where it would run on them especially as its only running 9psi or so?

Try the greys and see if it starts. Dont bother swapping the mani swap just the injectors and see if it runs. Then you will know for sure if its a fuel problem or not.

In a crude way yes, when in closed loop fuelling it would be trying to compensate and that does affect the open loop fuelling also... but not ideal by any stretch, its only like that to take into account small changes from things wearing out with time and changes in the environment etc, not so much a 20% change in injector size

You can run far larger or smaller injectors than normal and have a car drive seemingly just fine, its only when you push the loud pedal that it becomes a bigger issue

Out of curiosity does the car have an aftermarket reg on it as well?

Yea thats what I thought. This should be a reduction from 440 to 380cc or whatever greys are. If the coil pack was mounted in a factory fashion I would start to believe in funkys phantom V4/5 fuck ups.

How many bolts on bellhousing out of interest? Wonder if thats P1 or 2.

As above. so im probably over fueling with the yellows. I bought new plugs today but still no luck of getting it started. just more puffing out the exhaust. It sounds like there is air being released some where after a few cranks but im not entirely sure where. Is that normal? could it be that the injector seals are damaged and there is pressure leaking causing it not to start? either way im going to have to pull injectors out again to try the greys or check the seals. how can i tell whether or not the ecu is a genuine j2? If i pull it out, open it up and take a pic will you guys be able to tell? It should be though cause from what i gather, the earlier model ecu\'s dont fit the v5/6 loom.

If your cranking and cranking and no starty starty then it will blow back out the intake (or sound like it) what it is is the engines sucking and sucking and trying to prime but the excess air has no where to go so comes back out. Entirely normal. You might even get a back fire.

[whatshouldiget?]

no aftermarket reg. Ok so i reinstalled the greys. Bloody hell those yellows took a bit of muscle to remove. I gave it a few cranks but the same result. Battery died after a few attempts but will give it another go tonight when i get a hold of the jumper cables.

I would be checking spark now

[Guest]

Right, to get out all right, even worse in place too.

Pm subirex dude get him to cast his trained eye over it. If I was closer I would come check it out (not that I would be any help). Somethings got to be not quite right.

[Marky]

You mentioned a change of manifold

Are you 100% the new one is fine and sealed onto block properly? Its the only other thing which changed rignt

[lachlan]

you didnt plug the passenger side cam sensor into the injector and vice versa did you ? think it is possible and has happened before

First thing I put to him cam sensor wasnt plugged in. Must be right way round for it to get fuel on the plugs.

[Subirex Automotive]

where abouts are you located? i can come and have a look at it for you

[whatshouldiget?]

yeah cam sensor is in correct place. yeah mani was swapped over. I had a look at it today and i noticed that the gasket on the passenger side isn\'t correctly on the tabs on the block but the rest of it is tight down. could something like that be a issue? i swear its probably something really simple that i just keep over looking. It\'s always the case with me lol. i always miss the smallest things

[boon]

Is the AFM plugged in?

How far away are the holes from lining up?

What torque did you bolt the manifold down to? 18ft/lbs?

New gaskets?

[Guest]

There are 2 little studs each side which hold the gasket in place then it cant get pinched or anything. Normally start and die with a vac leak.

[Rosssub]

What about Throttle body/IACV/TPS changes between version 3/4-5/6? Guess CEL would trip if that was an issue?

It was working before with same manifold well same style. Guessing the idle control thingy is in but unplugged.

[Rosssub]

Unplugged IACV would trip a CEL too? Unless the CEL bulbs been wired to the ABS light and the car has 256 stored fault codes...

Long story. Short version - v5/6 body and loom, v3/4 long block and intake mani w/p1 greys but v5/6 tb.

so you trying to run v3/4 sidefeed yellows with a v5/6 ecu expecting topfeed injectors?

a v3/4 intake manifold will need the idle control blocked off if you are running the v5/6 throttle mounted ICV

what is this setup i don\'t even

i require pictures of all things

V5/6 are not top feed they are p2 yellow 440cc side feeds. Pics above in linked thread. Looks like a plate is over where the iacv sits on the early mani.

[kamineko]

derp yeah. i was drawing attention to the P2 style injectors. are they driven any differently by the ecu compared to P1?

The greys were p1 also...so doubt it.

[czar loc]

any differences between p1 and p2 yellow 440cc?

ok. but its assuming a lot.

anyway - once you\'ve installed the injectors, unbolt the rail itself with installed injectors, raise it out of the manifold, then prime the fuel system. if its leaking you will soon know where.
