Commodore 3.8 HELP!!

[COMILUX]

Hey guys.
HELP PLEASE!!!!!

Ive got a holden 3.8v6 from a VR commodore in my hilux.
A weekend or two a go it stoped on me while throwing it around in the mud.
At the start it would idle fine and rev fine but when under load wouldnt rev atal and then it stoped and wont start any more.
Has no spark or injector pulse so replaced crank sensor and still no go.
Makes me think it might be ecu but how could i diagnose this without buying one and trying it?
Any other posabilitys that it might me? Anyone had similar problems before?
Does anyone have a vr engine ecu in chch that i could maybe borow to plug in to see if its the problem.
Any help would be great.

Thanks
Nick

I can get the ecu out of my mates monster suzuki thing hes bilding and hook that up and see if thats the problem its a VN ecu i guess there the same

[H2OLOVA]

Could always visit a carsales and take one for a test drive

[rokhound]

Has it got the factory ecu or an aftermarket one?
Holden ecu's are super simple for those who know their way around them. (the v6 I believe is a 1 wire hook up). There is a holden wrecker in Gasson st who may be able to help you out with another (or loaner) box

[COMILUX]

Ok where would i find that normaly?
Are you able to test ecus at your work?

[radar21]

bottom of the coil pack at the end its got a 8mm bolt in it check that its got power and that its tight and that the plugs not bent nah we send them to nelson a place called anything electronic

[COMILUX]

do they call that the DFI unit?
i bought a coil and a DFI unit of trademe but it apares hes done a runner with my parts and money

[radar21]

yep direct fire injection the dear part of it all .that sucks that the guy made off with your money

[radar21]

IGNITION sorry not injection im away with the faires at the mowe

[COMILUX]

Tryed coil pack and dfi today but still no go, one i used is from a vn series one but was told it would work fine so hoping that not still my problem, takes me back to the ecu now tho. hope i can find one to borow and try if that fails ill admit defeat and give it to someone thats smarted than me with auto sparky shit.

i was gonna say coil pack as well.... Nailz on here had a RX7 with a 3.8 which developed similar syptoms, and it was coil pack, turned out ants had made a home in it....
but if you swapped coil packs then obviously not that.
