Hard Starting


Ronbo

Recommended Posts

Removed my check valve this morning. Found a lot of crud and a piece of paper inside. I was looking at the o-ring in side and it looked loose. I was trying to seat it and the whole thing came apart in my hand. I replaced the internal o-ring and re-installed. It started up without delay and did the obligatory stumble when the air hit it. It then idled and appeared quieter than I remember. We shall see how it does later today when I move it to load the jeep.

I put over a million miles on a 98 Volvo with a N14. It took a while but I discovered it mattered what brand of fuel filter I used. It would be really hard to start after a filter change and hard to start in the mornings. Fleetguard (what you get at a Cummins or Volvo dealer) or anything built by whoever makes their filters were the culprit. I generally used and carried Baldwin.

Fleetguard is a wholly owned subsidiary of Cummins, Inc. and is the OEM filter for all Cummins engines. Are you suggesting that the Fleetguard filter is an inferior product?

I know there was a thread and numerous pictures on this forum several years ago comparing different filters. They were cut in two and pictures taken. I also believe the author was RandyA (TheProfessor at that time). Couldn't find it by search but if I recall the Wix didn't perform so well. Also if my memory serves me correctly (always a 50/50 shot ;)) the suction collapsed the internal components of the Wix.

Fleetguards are pretty good in any testing you can find. I'd be interested in any further info on this backed up with any facts possible.....not just "Dodge is better than Ford". I had to put a Wix in my truck in my little adventure with bad fuel....but I'm happy to switch it out of the 382. It is pretty simple to do.

Trucksaledave (I thiink that's the right spelling) was the one with where the Wix trashed his engine.

He hasn't been on for awhile..

Years ago I installed a new filter and started the N-14. It was normal to be a little hard to start so it acted normal.

The next day I thought maybe the filter was not tight enough so I twisted it on a little more. Now the truck will not start. loosen the filter and now back to normal hard starting but it will start.

This is with NAPA filters.

It is not just the brand of the filter, although I have used all the majors and never had a problem with any of them. There are several part #'s for a filter for the same application, usually the differences involve the size or capacity/flow in microns. The guy who sells you the filter behind the counter has no idea that there are differences. Start with taking your engine serial # to the engine manufacturer and get the correct original filter # from them and cross it to other brands if need be. Of course many of these trucks have had modifications done to them, but getting back to the original configuration is a help. A filter with the wrong micron rating may cause problems, particularly in close to gelling conditions. I always ask the Freightliner dealer to look up the vin just like any other part and let them sell me part# originally installed. I have kept track of the correct #'s over the years, but they get superseded all the time, so sometimes that leads to a dead end.
