Killed my bus

[Pepperami]

Trying to sort out my cutting out problem today using a new vss. Thinking i had worked out where i gone wrong cut the wire and joined them. Now the FI wont switch on it turns over but wont prime. Reconnected the old wire and it's exactly the same. Checked connections, fuses ????????????????
It's all beyond me.

tony,
Ignition on lives the fuel pump relay which primes the pump.
Once started the ECU fires the relay to keep the pump running.
Check the Voltage at the fuel pump relay for 12v with ignition lights on.
If no volts there then check back to ignition fuse.
First things first slow back track.
Has the van fired at all since even a possible quick run and stop?

The engine turns over fine but hasn't tried to fire at all. When the ignition is switched on it doesn't make the whirring noise (prime pump). Cheers i will check over as you have said.

Ok just checked the fuel relay and between terminals 3 and 4 it is showing 14.29 volts. The 15amp ignition fuse is fine.

Peps sounds like wneh mine went breasticles up try a perm feed to fuel pump so keeps gooing all time if runs then pump is ok then didtch the silly metal round relay and put a 30 or 40 amp normal auotomotive relay in its place once i did that it worked fine I allso move d the relay into a cool area !

Where did you have yours James. Mines under the rock and roll by the slider. When its running you can really hear the fuel pump (loud). You have a bmw pump don't you?

[Pepperami]

Tried diagnostics nothing happening there.

[jamesc76]

Mine was in the engine bay now next to the flap, yeah mines a bmw pump but thats the same as others the scooby relay is a metal cylinder one that plays up alot! once i binned mine it was fine

[Pepperami]

Have put a normal relay in still nothing. Have just dusted down the race bike, just in case.

Sounds like you are missing 12v to the ECU?
Cant remember if Richard put an Ignition fuse on the ECU?
Fuel pump relay Pins 1+2 Yell you should see with ignition on 12v ish.

Pin 4 Black Red live to pump on prime and running.
Pin 3 Light Green Black to ECU via a diode. Its this signal that grounds the relay making the connection.
If the ECU has no Juice then that function will not work.
On the original Subaru diagram Pin 2 is fed via the Ignition relay.
Pin 1 also feeds the ECU!

Of course the ECU might have volts but have a fault.
If you say even no diagnostic operation then it still points at a voltage loss somewhere.
Lets not forget I could of course be completely wrong and barking up the wrong tree.
And also I have probably got the wrong year wiring diagram!

Thanks for all of your help with this desperate matter i will show the mobile mechanic all of your replies on Friday.
It all confuses the hell out of me with all of the different colours.
Have resorted to using this now!

How are you going to mount the RnR Bed and Propex on that?

[syncroandy]

Have you got the wiring diagram ?

[Pepperami]

No i only have bits of info about it and problem solving stuff from usa. It is an RJES loom with a small car vss.

[jamesc76]

Get in touch with rjes gett eh,m to email you the diagram for the mechanic to look at would be best bet? Nice crosser tho!

[Pepperami]

Cheers James done.
