GU ZD30 Cranking but wont Run

Just had mine do the same thing..

Mechanic did following:
got error codes 76 - Fuel quantity solenoid valve signal improbable. 73 - pump communications line open circuit/short circuit.
Carried out a pump PSG scan. no pump codes were found.
Fuel filter replaced as slightly dirty.
Checked fuel tank and found black oil contamination throughout the main rear tank.

So mechanic advises to remove and clean the tanks then fit a new pump.

Looking at over $6k all up

Not sure I want to plow another $6k into a 2000 patrol..

There should be enough dead ZD30Di around the place to pick one a fuel pump second hand?

Just read it on face book..
$250 to plug his computer in...
Crazy

I had the same problem in Alice Springs.
Could bet my left testicle it is the injector pump.

The sub tank pump is a transfer pump only, not related. It will transfer fuel when you start the car but only for a few seconds.

When my old ZD died it was the pump that went. Error code 0703. In a nut shell the circuit board on the pump was fried.

I think its from page 27 for all the codes.

Hey Guys n Gals,

Well I been having the odd issue where powers dies when I press accelerator pedal but when I double tap it comes good, had codes read other day and it came up as Accelerator Module, had a major service done & left battery discon for a hour or so and all was running well until today... no rhyme or regularity to the issues so far.

Went to a job out of town and got 5ks out did a uey and went to take off, power was good then just died, and engine stalled, hasn't started since, cranks OK fuel filter is priming up hard after 1 or 2 pumps but after cranking goes soft again, no evidence of fuel leaks and all fuses are good..
Will get under it over the weekend see if the fuel lines are all good also check all wiring as the issue only started after I hit a small roo the other week, no damage aside from original plastic bash plate of sorts...

Any other suggestions aside from one previously mentioned would be appreciated, I will be going through the previously mentioned tips over the next few days prior to sending it into the shop.

Anyone know of a shop in the Lower South East SA (Mt Gambier) area rebuild fuel pumps etc...

Cheers Lads n LAdettes hope ya footy team gets up which ever ya follow.

Update on the dreaded cranky but no go....

Had the beast towed to the shop this arvo and yep codes for pump etc.. dead fuel pump quoting $4500 replaced with rebuilt unit from Adelaide.... not the news I wanted to hear but it was expected, lets just hope that's all that's up with it.

Take it easy you lot

Yeah thats what happened to mine last year. Or similar. In the end the pump was dead. I wasnt prepared to spend that kind of coin on a ZD30 so i spent more and did the td conversion.
Lucky though. As after the car was finished, the head was removed off the ZD and found that number 4 piston was cracked. So yeah, i could have spent 5k on a motor that had the pin half hanging out of the grenade...
