Car Forum / Isuzu Cars / August 2006Fuel Filter change cause of starting issues?
Recently I changed my fuel filter in my 2001 Isuzu Rodeo 4WD LS with 74k miles. I replaced it just because I figured it was overdue. Ever since replacement I have been having issues with troubled starting. Sometimes the vehicle starts right up. Other times it takes 3-5 seconds of cranking before it gets going. Once the engine is going, everything appears to be functioning normally. The starting problems seem to occur more often after the engine has warmed up for a while and then shut-off for a short period. Could I have maybe installed the fuel filter backwards or something? It looked very similiar to the old fuel filter and I installed it in the same direction as that one. Could be it was installed backwards. The ones that I have seen that can be installed backwards have an arrow indicating the direction of fuel flow - that is the arrow points toward the engine. Could also be that if you "top off" the gas tank the evaporative emmissions canister (aka the charcoal canister) is flooded and needs to be replaced. If your old filter was slightly plugged and the charcoal canister was "full" it may have been able to make up the loss while starting the engine and now it is being flooded. I had a similar problem on an '87 Toyota. I haven't topped off my gas tank since then. Sorry, I don't know of a way to test the charcoal canister. > Recently I changed my fuel filter in my 2001 Isuzu Rodeo 4WD LS with > 74k miles. I replaced it just because I figured it was overdue.

I'll look into this. Hopefully it is cheap. |
