remote start not working, 91 chevy van

I have 91 chev van (starcraft convertion ) it has viper alarm and remote start. It is about 7years old . Everthing works alarm wise . When i try remote start it goes through all the motion ( dash lights up engine light comes on and just sits there . the starter does not engage or turn on . Could it be the hood sensor ( safty senser that stop engine from cranking remotly when open . How can i bypass it temparatly .

Do you think this is what it could be . It is rusty >

there is also a but under dash to push when setting remotes and what ever

thanks

if it is safty mode how would i remove it . It does have the valet button I cant remember what to do to use it. I think you put the key in turn on key and while pushing valet butten .or somthing like that how far off am i

any help would be great

thanks

where is the fuse located . how would i trace it

would it be high up in dash where you have to take dash apart
