Does the 03 H2 have this module or is it just the relay?

 

there might be something on the firewall around or below the hydroboost area i dont recall if it is the fuel pump module. it you have air suspention there should also be other modules /relays there but as my 03 does not have air suspension i just saw one module.

 

Mine has air ride. Problem is I have the crank no start but sometimes starts but won't stay running. Guess I'll crawl under and see if it is in same spot as on the 06..

 

you might see it better from the top drivers side.behind the fuse box / hydroboost/ steering shaft area. tucked a bit out of the way.
