Once it starts- how does it run as soon as it fires on gas & lp? I would run a tank full of fresh gasoline plus an additive called "Sea foam" - I've had great luck w/ this product for cleaning out gummed up gasoline fuel systems.

As far as the lp fuel system- no fuel system cleaners as of yet. If it won't start on LP then a system rebuild is in order.

Customers love technology- until they have to pay to fix it!
OK OK NO NEED TO YELL ABOIT IT....LOL

being that its sat for a year it could be that the duel system is all gummed up on both the gas and lpg side.........ignition and injection is controlled by signals from the cam/crank signals somcould be a weak signal there at cranking. Also check and clean or replace the MAF sensor this plays a part in it also.

I would start by getting one fuel system to work/operate properly by either going thru the gas sytem and changing the filter and cleaning the injectors somehow. On the lpg side i would start by cleaning or rebuilding the NIKKI regulator and checking the injector holder and injector and cleaning any tar junk out.....

What engine does this truck have in it.....Nissan K21/25?

Hope if you changed plugs you used OEM original NGK plugs,aftermarket,parts store plugs dont work well in these nissan engines...

Guess without knowing what engine is going to be a guessing game......still might be a guessing game after that

You could start by replacing the spark plugs.
