460 ford engine. Not starting

Actually, Mitch has a good suggestion. On an EFI system, if you hold the pedal to the floor while cranking, the computer will NOT energize the fuel injectors. That way if it is flooding it will clear out and start. If that doesn't help then it sounds like you are not getting enough fuel pressure in which case it is likely a weak fuel pump. Common problem with the EFI 460 chassis.
BTW - while your coach is a 1998, the Ford chassis would be a 1997. There were no 1998 Ford F53 chassis made.

It is 7.5 EFI engine

Thanks. I should of mentioned it we checked and you can here it come on.

Not getting fuel if it runs on the ether... 1998 should be EFI...

EFI would have an electric fuel pump in the tank.. Lay under the gas tank and have some switch on the ignition and you should hear the pump run for a few seconds.

You might try cranking it with the pedal floored.. Yes, I know you normally don't have to do this with EFI, but it's something to just try??

Good luck!

Accelerator pump,in carb not putting fuel in motor. Is it carbureted or throttle injection or efi.
