Hi first time posting here since I can’t find my solution anywhere else
I have a 2007 Freightliner Columbia with a 14L Detroit 60 series engine
The truck was running perfectly fine until one day it would crank but would NOT start.
Now it only starts with starter fluid. BUT once the truck has been running it starts and shuts off with no problem.
——-
I’ve checked / replaced
electrical - batteries, starter, fuses, starter solenoid
Other - Fuel/water separator and the check valve behind the engine
and I’ve even used fuel injector cleaning fluid
When I changed the filter of the fuel/water separator it would start but very faintly
Now here’s the thing … I come to
You guys because I don’t know what else to check and my mechanic is suggesting that it can be the injectors but truck runs strong once it’s on, so I’m doubting it’s the injectors
HELP! TRUCK ONLY STARTS WITH STARTER FLUID

Does it smoke while cranking? No smoke means no fuel, could be fuel draining back or the fuel transfer pump could be weak. Chech fuel pressure.

I’m not 100% positive on this but seems I’ve heard using starting fluid is a bad idea and can cause a bunch of other problems
I know you need to do what gets it going but if what I heard is right. The sooner you fix the issue the less chance of a snowball effectDon379 Thanks this. -
Check the timing sensors.

A bad srs sensor will act like that, I would probably replace both srs and trs sensors at the same time. Just a guess without a scanner, but I have seen that same thing before and it was the srs.
jamespmack, blairandgretchen, Rideandrepair and 2 others Thank this. -
If the problem started around the time you changed the fuel/water separator, perhaps you have a leak at the filter?
Rideandrepair and Supplychain2019 Thank this. -
