I cannot get the effing thing to start

Prehistory: Driving home Thursday: gave it a bootfull (on LPG) and it reved out to about 4500, backfied beautifully, coughed, and died!!

Pulled over to edge of road, cranked motor, and it started (LPG) :D 8-)

Drive on: Gave it another bootfull, (LPG) and it coughed,died and would not start. Called RACV, confirmed no spark: flatbed home ( :( 8-) )

Now, here is the progression:

1) checked interior light and fuses: all O.K.Checked rest of fuses, all good

2) Ran multimeter over all other fuses (e.g.: Main, Ign etc ) no problems

3)Changed TFI module (ignition module):no result: no spark!!

4) Changed coil: Ditto

5) [i]attempted to start, cannot hear injectors running when trying to start [i] but can hear fuel pump priming.

What I have left to do is: a) change ECU relay (gotta spare )
b) change ECU (gotta a spare too 8-) )

in that order :?

Is there anybody out there that has any other ideas??????

Gotta get the effing thing going this/ w/end

Is it even cranking? If not, have you tried the BEM thump?

I have tried everything, including the BEM thump.

This morning I got to it, and the bloody thing started and ran well, both petrol and lpg. O.k. I thought, I will stop it and see if it starts again.

Nothing...no spark again

Cranks fine

Changed ECU's (twice) no result

Spark plug, when removed, is dry. I am thinking that fuel isn't getting thru?? But that wouldn't stop the spark

power is to injectors

Changed TPS, no difference

Ran a diagnostic check, no fault codes evident

I am at a total loss as to what it is.
