did you just put the FASS on??
if you already had the FASS then never mind and my guess would be VP44
have you checked the codes yet??

Have you checked the filter and fuel lines?

The Fass is supposed to run a few seconds and then shut off. To much pressure and it won't start. You and turn key on and then off to get it to run 20-30 seconds and then shut off. It will throw a code it it runs continuously when trying to start

I have not checked the codes yet.The fass filters are always changed every 20000 miles 5ooo miles ago when low sulfer fuel acted like a solvent and cleaned my tank, 4 filters in 2 days. I pulled the fule line at the ip and the fass is pushing good no air. WAIT IT DOES TURN OVER A "LITTLE LIKE ITS A DEAD BATTERY, LIKE MY CYLINDERS ARE LOADED UP. Dont have a reader cant check the codes??? what to check next? Thanks so far everyone for the input

turn the key "on" and "off" 3 times and on the last turn leave the key on then read the codes displayed on the odometer and tell us what you find.
try jump starting it too.

P1291 is the code its throwing manufacture fuel air metering. I broke down and bought a obd 2

it might pay to check the oil and charge/jumpstart. if the oil is up or stinky...you have problems, if the batts are down it could be your problem, or at least some of it.

I would have your batteries load tested.
SYMPTOM
P1291-NO TEMPERATURE RISE SEEN FROM INTAKE AIR HEATERS
that's what I found on that code, if the grid heaters are not coming on then it may be from weak batteries.
