NO START HELP & ADVISE NEEDED Badly

[Scooterdog]

Ok a few threads down I posted my truck was running fine and the next morning it turned over but rough idle and lopping then died, would not turn over again.

Replaced the CPS, New fuel Filter, draind the fuel bowl and then put in some fuel in it, and had both batteries fully charged because I drained them. All this was today...

Go to start and no go. Starter spins the motor but does not kick it over. Now my check guage light comes on and my battery light is on. Got up into the engine and took out fuel filter and had my son turn it over to see if there were any signs of fuel entering the bowl, no go.

I can hear the fuel pump but have not checked to see if its flowing as it was getting dark and its like 35 outside.

Last my AIH relay is squeeling like a pig. Will this cuase it not to start? will this cause the battery light to come on? lots of questions but have not had a solution.

I'm at a loss here and need some real help from the pros...Thanks
