Working at 6480 that won't start teir 2 electronic injection pump Perkins engine was wondering does anybody have wiring diagrams or know how many lives should be at the pump

The engine doesnt fire up until sensor on engine senses it turning at certain speed. Don't know speed im afraid. Be worth checking sensor that reads this too.

The bosch vp44 injection pump fitted to these tractors is unreliable . Ive just went through same issue with ours.

Ended up ecu replaced and new fuel pump and big bill.

 

[Bloders]

Is it common rail or the Bosch VP44 type pump
Any error codes
Have you tried bypassing the stick of dynamite fuse? (Next to pump)

 

[Jabk]

Funny I don't think the engine is turning quick enough even though there was two new batteries and a good starter off a 6270

[Jabk]

It's the Bosch pump had no power coming to the stick due to earth problem at relay got it sorted and have one power to the stick and it the heads to the injector pump

Vp44's just die
Ecu will be fried And pump body worn
1200 for recon pump

 

[Jabk]

That The ECU on the pump or one on side of the engine

 

[davidroberts30]

On the pump

 

[Jabk]

Any way of testing it

 

[Chae1]

Could you get another pump to try on tractor?

 

[AWJ26]

Check the ignition switch first, had a vp44 pump reconditioned on a 7480 that wouldn't start and it turned out to be the £30 ignition switch!

 

[Jabk]

I don't think I have access to another pump I think my switch is ok and I have power at my fuses the lazy turnover is puzzling

 

[Bloders]

is it turning over slow?
crack an injector - any diesel coming out when cranking?
i fitted a car injector to an old injector pipe when messing with ours (6460) and no diesel coming out of it.
have you checked power from the dynamite with a bulb or multimeter? ours had 12v but when tested with a load, no power behind it. I bypassed the dynamite and worked fine then

[Jabk]

It is turning very slow there is a small amount of diesel at the injectors what way do you bypass the four wires on the stick

 

[Bloders]

first thing is to sort the slow cranking out.
- flat battery
- poor connections
- knackered starter
- partially seized engine
then its cranking crrectly, look at the other bits.

I worked out whihc was +ve and -ve into the dynamite, and out of it (used multimeter), then bridged the connections with some fuse wire to test it. Proved that was the issue then semi permanantly bypassed it until a replacement was ordered and delivered.

 

[Zetor]

Check there's not a hydraulic spool not stuck on constant, would cause slow starting

 

[Jabk]

Wonder if the starter from the 6270 had a high enough capacity it turns the 6270 quick the engine turns free with a bar at the starter ring I wondered bout sticking spools and turned over with a guage in them but it didn't seem to pressurise

Try giving the battery’s a good charge or jump it off.to see if it turns over faster.it won’t start if it’s not spinning fast enough.
