Fleetwood Tioga Montara Wont start - fuel pump?
« on: January 28, 2012, 01:55:27 PM »
After sitting for a year, I am unable to start my 95 Tioga. It is a Ford chassis with a 460. Spark is good yet no fuel it seems. The tank is full. Energency cut off switch is okay also. Any suggestions of how I can troubleshoot the fuel system. My guess is the fuel pump is frozen up but I'd like some experience before I assume that it's shot. Thanks!

Any suggestions of how I can troubleshoot the fuel system.

To properly test the fuel pressure you need to attach a pressure gauge to the port on the fuel rail. If I recall right, it should read 40 psi minimum for a Ford 460. You should check for the specs on your specific engine.

BTW, if this is the original fuel pump and it is not equipped with the new design fuel pump, it is past due for replacement with the new pump.

Just guessing... I presume we are talking about a standard throttle carburetor.

If not and if it is a TBI injection system (Throttle Body Injection) there may be another problem.

If so, I may be able to give some unsolicited advise.  (From a GM TBI system).

That vintage of Ford fuel pump is notorious for failures - if it has never been replaced, it is probably time.  I would start by simply disconnecting the fuel line at the carb or TBI inlet and see if fuel pumps with the key on.

A '95 Ford 460 will be port fuel injected and not TBI. In any case, the only way to determine the actual fuel pressure is with a gauge. Since the OP has narrowed it down to a fuel problem, the next step is to determine the actual fuel pressure.

Simple things first: what about the fuel filter? He said the coach has been sitting a year...

Have somebody stand next to the fuel tank then turn on the ignition. The person standing there should be able to hear the pump as it charges the fuel system.
Is there voltage to the fuel pump?

I always try the simple stuff first
