     I just changed a leaking fuel fitting as Jack suggested and it worked great.  Now I have developed a slight hesitation in getting the starter to engage.  Both the front and rear starter switches act the same.  When I push the button in front or throw the switch at the rear, it takes about 3 tries before the starter spins the engine. The first couple of tries act as though the battery was low, (they are fully charged), the starter tries to spin but then nothing.  On the third try it spins and the engine fires right up.
     Are there other relay solenoids other than on the starter itself that could be causing the problem?
       Thanks,  Iver.

Does your system have a fuel pressure switch in the starter circuit. Perhaps you disturbed the connections when you made the repairs.

Here is the proper way to diagnose your problem as per Gerald Jenkinson, the Grand Poobah of diagnostics.

I would pull all your grounds in the engine compartment and sand them shiny. Those things get really corroded.

it is a dirty job though...

Sorry... forgot to suggest that you do the leads to the starter as well.


hope this helps.

I think Paul & Rick have this one. We were getting the LUG LUG LUG with no start on our 8v92. Checked the Batts.=Full. Found a loose ground cable @ the batt. ground. Went ahead and cleaned and tightened all the batt. conections. Now it starts with a touch. MAN, that Big D sounds good. I got it Bad!!! Grin Grin Grin All the Best, M&C

As other said, check ALL the connections.  Look for one that is hot after starting.  What is likely happening is the first couple tries are heating up the bad connection causing it to swell and tighten up just enough to work.  Soon it won't.

Good luck

A bad connection will get hot, use an infrared thermal temp gun and point it on any termination, this includes all distribution panels including your house system. It's also a good idea to tighten all terminals once a year, electrical current does strange things to wiring and terminals, including all grounds. Keep the smoke in! Wink

Did ya get the part about the poor connection getting hot? Huh Roll Eyes Cheesy

I think the most probable connections to go bad are internal to the starter.....1 and 2?  The next are in the relay.

If you don't have a thermal gun...get one.

Really important here:  Get some silicone grease like the stuff they use for spark plug boot release or cheaper but just as good SILICONE GREASE and coat all the connections with the stuff before you finish the connection.  You will never have this problem from that component again.  Toy pasks their light bulb sockets with the stuff to preserve the good contact you get when the parts are new.

If all the above fails - try load testing the batts - how old are they? FWIW

Hello:   Dont forget to check the connection behind the engine below the rail right side looking at the engine from the rear. From that connection one wire goes foward to the batteries; one to the starter; and one to the alternator.

Thanks everyone for all the advice.  The 8-d's are new. Pretty sure the fuel pressure switch is undisturbed.  I will start checking all grounds as a first step.

I agree with Tony.

If you just worked on the fuel system and the starter worked ok just before this work you probably have done something to the fuel pressure system. Not a lot of mystery there.

However, if it was a long time since you used the starter before repairing the fuel leak it is probably electrical connection corrosion.

There is also a starter relay in addition to the starter mounted solenoid which is small and often fails or doesn't work because of corroded terminals. This is usually the best place to look first because you can easily jump it with a small wire.

Gus,
   Actually I had the problem developing before the fuel fitting repair.
Where is the other starter relay that you mentioned?
    Thanks, Iver
