Vp 5ltr starts and stalls

[Kev ol bluedog]

I start it goes for a few seconds then stalls. Have replaced iac ,tps , air temp sensor, injectors, fuel pressure regulator, checked fuel pump . Problem still remains.

Only started doin it 4weeks ago when i took it to the drags. Up until then its never had a problem . At the drags it seemed like it was flooding cos the spark plugs were wet and now its the opposite. Take plugs out and they're dry..

Have replaced everything bar the hall effect sensor as i was led to believe the Vp 5ltr dizzy didnt have one?

The VP V8 has a hall effect distributor. Next time this happens, get an old spark plug , open the gap to about 8mm, fit it to one of the HT plug leads , hold it against the block with an insulated screwdriver and see if you still get a spark.

If you get a spark the cause is probably in the fuel system, if not look at the electrics.
