need more opinions/ideas

[VL Berlina 5speed]

well finally got the wiring done on my car and it turns over
last night was able to get it to run/splutter for few seconds but cant get it running

now i need more ideas what too look at

so far
set the dissy timing to TDC and point 1. cant check with light till it idles
new leads on it and plugs in, new dissy cap, new rotary arm
has spark at lead #1 and its blue arc
has fuel in the system (botom fuel rail pipe is rock hard and presursing)
injectors i cant tell if there working as i cant hear them with starter running
check all the usal plugs are in.
the cas was work fine when i last had it running

check comp and got the standerd stuff plus
starter circuit system
and dentinaton sensor (didnt wire one up)


anyideas i wanna get it idling tonight
cheers sean

Have you given it a good long crank? The fuel lines just be dry?

Have you tried the hose method for listening to the injectors?

[VL Berlina 5speed]

yer have been
done it that many times the battery is starting to die (from my vs)

tryed the screwdrive way but not the hose too loud as the starter is under the plenuim

[Calaber]

You said that you have the dizzy at TDC. Have you tried to advance it a few degrees then turned it over. If it's spluttering now, it might be that the timing is just a degree or two retarded from where it needs to be to start.

[VL Berlina 5speed]

i set it at tdc then turned the dissy over to where approx 15degrees would be
still no start

it has spark, its got fuel to the rail but is it opening the injectors is another question.
i might go try pipe trick, one sec

[VL Berlina 5speed]

injectors are ticking by the sounds of it

[danja]

Do you know if the valves are opening/closing properly?

Does it feel like its starting at all, or just turning over due to the starter?

[VL Berlina 5speed]

just turning over and over, no attempt to start
cant tell if the valves are opening or closing with out taking the over off

got someone on ct checking his car to make sure ive got the fuel line pipes the right way
ie return isnt connected to the fuel regulator

[VL Berlina 5speed]

just checked the spark again and only got a weak orange spark once

would test the coil with my multimeter but its dead
suppose ill have to leave it till tommorow and get a spare one

[Abrowne70]

yeah sounds like coil could be fault, but then again could be a number of things but atleast your narrowing it down, just sucks that your multimeter is dead

[detox_nath83]

Gday sean
process of elimination i would suggest :P
Fuel/Spark/
Can u smell fuel while you been cranking it for a while. back out a plug and check fuel.
Cant be anything to big.
Coil like u said. as well as power transistor on dizzy is working?

[VL Berlina 5speed]

can smell fuel when cranking for a while

forgot to bring my spark plug socket home
going to try setting the dissy one more time, might have it on the wrong cycle, possibly everytime have set it at valves open lol

couldnt get another coil today, if anyone local has one i can borrow it would be appreciated

any way you can tests the capcitor or coil with out a muiltmeter?

[Abrowne70]

i reckon i got a coil around somewhere, got a few motors ill have a look in a minute, im near marion but will probably be up o halleron hill way later tonight

[danja]

going to try setting the dissy one more time, might have it on the wrong cycle, possibly everytime have set it at valves open lol

Reckon the flames coming out the exhaust would let you know if that was happening

[VL Berlina 5speed]

well ive got the timing too the point it will run when you try turning it over
but
will only run for 3 seconds the splutters and dies

i think its a fuel issue, as after every time you get it to run for the 3 seconds it needs to re prime the fuel system, so its using the fuel but it wont continue the supply once running.
will only prime it


so looks like i might have to seach for some ways to test it

[VL Berlina 5speed]

well afm is ruled out now, cheers abrowne70


looks to be lack of fuel supply after primed
ill try a diff fuel pump i reckon next

[detox_nath83]

i would suggest the high pressure fuel pump...
your inertia is priming up your system enough to force fuel into injectors

[VL Berlina 5speed]

ill give the external pump a swap with one to see if that works before i strip the manifold to refit it

[Goon]

ill give the external pump a swap with one to see if that works before i strip the manifold to refit it

I had a lookie at ur vid man, try the plenum again if nothings happening, my car was sounding the same until i refit the whole setup again

[ari666]

bridge your fuel pump fuse in the fusebox so that it has constant power. you can take the hose off for a sec to see if it sprays out. bear in mind it will SPARY out.

then reconnect the hose and get your mate to crank the starter while you hold the timing light. the light will still work while it is being cranked, even if it isnt idling...

then check if your 180 out

[VL Berlina 5speed]

check the fuel, i am getting fuel to the front.
changed the external pump as i might of had low pressure but no dif
regulator is working as flow comes out the fuel return on the rail too

pulled the first plug out and its dry, not even smelling of petrol or any carbon on it

so injectors are not opening

unpluged the first injector lead and plugged a na injector in and it aint ticking when cranking

no wiring on the injector loom was touched or cut
only put condue piping on to neat it


suppose i need to look at trying a difrent compter now
tryed my na auto one but no luck at even possible running
prob because the injector cycle is diffrent apparently

[loveless]

this might sound silly but have you got the rotor button facing the right way? you could 180 degrees out, sounds silly but its easy to do lol

[VL Berlina 5speed]

on the rotartu arm one side of the shaft is squared off so you cant,
its was a good thought though



just been reading through some threads on CT and came across some post that MonstaS4 had posted

these are referring too the relay which was near the battery,
the metal casing relay i think we cut out, cant find it in the dash either (where most where moved too)

tested the injector and i have 12v to both the cables when the car has power running through the car

but then i get lost

if this relay was to be removed would the injectors work?

Forget the LED. Do you have 12v on one of the injector wires? (referencing one meter lead to ground). You'll have 12v on both wires with the engine off.

The 12v feed to the injectors is via the reverse polarity relay. With the relay OFF, you should have 12v to the injectors. If the relay is off but no 12v, then the contacts inside the relay are dirty and you should replace the relay. BEWARE it is a changeover relay (normally closed contact aswell as normally open). If the relay is on, then the diode hidden in the loom near the relay has gone short circuit.

There should be 2 red/black wires, an orange and a black/white. The red/blacks are battery 12v+ via a fusible link. One connects to the coil of the relay, the other to the "common" side of the relay contacts. Sounds like you have 12v on each of these?

The black/white is an earth for the relay coil, BUT.....it is earthed via a diode so that the relay will never come on unless the battery is connected up wrong (hence the name reverse polarity relay). Put the black meter lead on the black/white wire at the relay and the red meter lead on either of the red/black wires. The meter should read 0v. If it reads 12v then the diode is short circuit. Remove the tape from the loom and it will be hidden in there. Cut one of the wires to the diode and i'll bet the car will start.

If the meter read 0v, then check the orange wire for 12v (with the black meter lead on batt -ve). If you have 12v here but not at the injectors, you have a break in the loom somewhere between them. If you don't have 12v, then the relay is shagged. Replace it with a CHANGEOVER relay....NOT a normal relay.

i have just got another starter circuit loom so once i find time and daron is free we will look into it

[daron]

didnt see no diode sean but im sure at 1130 pm in the dark we wouldnt have hehehe
ill come up over weekend and have a look

[VL Berlina 5speed]

If you've removed the relay and haven't rewired the orange wire to battery 12v, then this is your problem. This orange wire also goes to the ecu. I'm guessing that it needs to be unswitched 12v....not ign switched 12v.

In saying this, you have 12v to both terminals on the injector plug which is normal. The ecu switches the injectors to ground.

a reply too my question before
hope its it
