Volvo FE42 problems starting

Sounds like a bad switch. If your handy you ought to be able to take it out and see. If not visible get elec meter and check. Sure that little guy has been turned a few times since 93'.

 

That is going to be your key to getting it fixed. Assuming everything with the starter is Kosher, you're not getting voltage to the starter when the problem occurs. And your job is to find out why.

I would verify that you're getting voltage FROM your switch when the problem occurs. If not, start by checking for loose connections and cleaning them. You're very likely to find the problem there.

 

Best thing would be take it to a shop for a diagnosis, then decide what to do.

 

On your Volvo, try this... First of all, the ignition switch is designed to only engage the starter "once" without shutting it back to "off" and starting all over. That keeps you from starting it if it's already running. That's why it jams up when you re-try to start it. When you turn the key (just short of engaging the starter), you should see the orange "zig-zag in a circle" light up on the dash for about 50 seconds before it goes out. That's the "pre-heater on" symbol. If it goes right out, you'll need to replace the 4" sheetmetal "fuse" which is attached to the pre-heater solonoid on the right side of the engine (1/2" nuts). Warning - the fuse ends are sharp if it's been melted. They're a few bucks at Volvo. Get a spare for the glove compartment and keep it in an envelope.
IF you get the pre-heater to cycle and it still doesn't start, go in behind the driver's front tire to the side of the engine. The first thing you should find is the shut down solonoid. Make sure the key's on and get under there and give it a push to release it. If it's sticking, that should free it. Keep that thing lubed!
As a reminder, don't use starting fluid, etc. because of the preheater in the intake. Also, with the Kysor shut-down on that engine, it usually requires some air pressure to activate the fuel shut-off, so it won't be able to shut down until it builds up some air pressure. If you run into having to immediately shut it down, you "may" need to get underneath and pull on the little triangular fuel shut-down on the fuel pump.
The FE's are rock solid trucks if you maintain them. Good luck!
