Spray a little starting fluid (ether) into the intake while someone turns it over.
If it tries to start, the problem lies in fuel delivery (fp reg./fuel pump/ fuel filter)
Unhook one of the coil packs & put a spark plug into it while grounding it to the block or elsewhere, have someone turn it over to see if there's a fat blue spark jumping the gap...no spark = ignition sys. problem.
Just a couple of quickies that'll get you going in the right direction.

ok, will work on that....anyone know if our vx's can be put on a 2-wheel tow dolly for about a 5-10 mile run?

Don't know for sure about that...have read before that they shouldn't be towed (4 wheels on the ground), so I'd be wary of dollying 2.Originally Posted by Ruflyf
Something to do with TOD as I recall.
However, you could dolly up the fronts & disco. the drive shaft in the rear.

If it is a low speed (under 40 to 45 mph) tow you are fine putting the rear end on the dolly and unlocking the hubs. Isuzu says that you can tow those transmissions in neutral for 50 miles at up to 50 mph. For you you'd want the transmission in neutral and the hubs unlocked.
Good luck!

Ok, got it home. I did try the ether and it does try to start after spraying it in the intake. I had my brother try to listen for the fuel pump while I turned the ignition to on and he could not hear it engaging. Soo, does anyone know if this is normal? Real quiet fuel pump on these maybe? Usually its a sure sign if you cant hear it, but I cant recall hearing it in the past either.
Thats about all I was able to do before getting it towed to the house, and I have to work 24 hours tomorrow, so its research time at work, then I can hit it hard first thing tuesday morning.
I know it was suggested that the fuel regulator might be the cause, but could/would it suddenly kill the engine, so fast as if I'd turned the key off? No sputtering or nothing. Although I have my doubts that the fuel pump would kill it so suddenly also, seems like it would sputter at least a little bit as the pressure was dropped. Any ideas? The good news is they are both easy to check and I have a fuel pressure guage, so I'll start on that tuesday morning.

i had a problem with my vx where sometimes at speed i would just out of nowhere lose my ability to rev above 1500 rpm.. the problem didnt happen often but i changed out the fuel filter and havent had any trouble since.. dont know if that was it.. but it probably couldnt hurt

^ I have the same problem. It happens maybe twice a year... cruising at highway speed then bleeeeah the more gas you give it the lower the rpm's want to go then BAM right back to normal again.
Then I have also experienced the quick shutoff and that has happened around 10mph as well. Maybe these are both problems with the fuel pressure regulator? I don't know.... this is wierd, as it doesn't happen with any kind of.... ruglartivity *my new word*. Everytime I just pulled off to the side in neutral and started it right back up, no codes or anything just right back to normal again.
I figured it had to be some kind of electronic thing that got wet or frayed from offroading , but now I think I may be more convinced about the fuel regulator.
