Ok heres the deal ,, I did some work on my truck yesterday. Nothing thats too big of a deal. I changed my fuel filter, oil change, and a changed my rear end gear lube. Now my truck won't start!!! What could I have done when changing the fuel filter to screw it up. It started yesterday after I put the new filter on but I had to turn it over for almost 10 minutes, I thought I just didn't prime the filter w fuel and it was filling up. Now it won't start at all. Did I do something else??? Maybe the glow plugs ?? I don't know .........


help a brotha out

Thx

I think I just read a post where I might have burn't out the glow plugs from turning them motor when I didn't prime the fuel filter ....



any truth in this ....

 

was the motor warmed up when you changed the filter. check the resistance of the glow plugs if they are over .02 ohms change them.plug it in maybe take the fuel filter off and check to see its full still

 

ummm I just used some starting fluid and its good to go now !!!


WHOOOOOPIEEEEE !!!

 

Don't forget to top off the new filter with diesel when you change it or else you will have to turn it over endlessly before it primes !!!

you don't want to use starting fluid It wreck the glow plugs, at least you got it going again

 

well it runs now , but it doesn't start as easy as it use too. I use to be able to just turn the key and VROOOM , it started. Now It has to cycle around a few times before it fires, at least 5-10 seconds beofre it starts now.

Anyone have any ideas ??

I used the bleeder to drain any air from my fuellines, but that didn't make a difference.

Anyone have any ideas ???

Make sure your fuel filter is real tight or she might suck a littl air

 

It's actually pretty dangerous to mix starting fluid (ether) and glow plugs. Any time you use starting fluid, you should disconnect the plugs.
I'd check all the glow plugs. As stated in a previous response...they should read 2-3ohms each, with wires disconnected. If they read infinity, then the plug is bad and should be replaced.

Found out that I fried the started some how from trying to prime the fuel filter after installation. I put a new starter on today and it starts great .....

 

Hmmm...betcha that wasn't cheap. Next time try to limit cranking to 20 seconds or so at a time.

In addition to what was mentioned by other posters, if you experience unexpected surging, hard starting or rough idling, be sure to check for the existence and correct operation of the OEM water seperator on the firewall, driver's side. I replaced the OEM unit a couple of years after buying the truck (new) and fuel system anomalies completely disappeared. Just fill the new fuel filter with diesel (I use a hose from the bleeder with the valve stem out just prior to replacement) and depress the bleeder while cranking and starting the truck (with a container to catch the fuel) after the new filter is in place. I crank the engine from the solenoid when doing this operation.

Something else to watch out for is air leaking into the fuel lines when the engine is off. Worn injector return O-rings and hoses can leak air in even though fuel might not be seen leaking out. I replaced the o-rings with Viton ones and installed worm-drive clamps (tightened only lightly) on the hoses.

Regarding glow plugs, when the engine consistently becomes more difficult to start cold but is OK warm and you've ruled out air intrusions into the fuel lines, likely the glow plugs are going/gone. Some might still work but cranking times will get longer as more fail. I replaced the ones in my truck at about 140K miles with Motocraft units from Autozone. Cost was about 80.00/set.

Hope that helps! Glad you got it going....
