Argh...

Dads Van is broke down, Going Crazy 3.3 v6 Runs Only when you pump the gas. Hold the peddle half way in where it should run at high rpm's dies right out.. Replaced Idle air Control Replaced EGR Valve Pressure in line seems good... Maybe some type of electrical malfunction? Really appreciate any ideas as we are out and hes going to loose what little hair he has left..

Thanks

P.S Dunno if it can be tested with a diagnostics in its current state, doesn't really run/idle It does run but only if ya pump like crazy on the gas peddle

Have you checked the fuel pump pressure?

How about the gasoline filter ?

How about major vacuum leak?
