Series 60 hard starting

look for bubbles in tank fuel return line. could be injector seal issues. just search block at top right, lots of info there. ask questions in different ways if you don't see what yuo are looking for. detriot, 12.7, 14, not start, air in fuel etc.

 

So what do you do to start it?

 

I knew someone with a series 60 who had a similar issue, he had the overhead adjusted (valves, injectors) and the problem went away.

 

I had a brand new Volvo with a Detroit I bought new in 1996. It did the same thing. It would lose prime when it set overnight. The mechanic that worked on my truck put some sort of loop in the fuel line. That took care of the problem but I don't know exactly how he did it.

 

Is the truck equipped with fuel flow switching valves? These would be hand operated 'pull / push' valves that are accessible from the fuel fill access flap. If so. they tend to wear out causing a hard start problem. Replace them with regular 'T' fittings or with OE valve if you wish to keep it original. If you use 'T' fittings make sure & keep everything level. Otherwise it could cause unequal fuel levels between the tanks.
