Let me see if I have this correct.
1. Ford and GMH are pulling out. So no sales there.
2. By your own admission, the price of LPG is going to leap upwards this year making it uncompetitive with petrol.
3. The global market is slowing and effectively heading into depression territory. So that rules out North America, Europe and China.
4. China copies most things. Read no sales there and they will dump into other markets.
5. Once the new pump issue is resolved in 3 months - then approval testing will start - count on another 3-6 months for this if there are no problems.
6. The initial patent is from 1990. No doubt this has been improved upon by other competitors over the last 23 years.
And you still want people to invest in this?
