Hey guys I need help. My 7.3 died and I can't get it to start. Let me recap what happened. I changed the glow plugs and got it started. While running as it should have been it all of sudden died. My first thought was I run out of fuel being the the gauge doesn't work anymore. I got it primed back up but it still wouldn't start. I checked the fuel shutoff solenoid and its working. I can give it a shot of ether and it still will not start. What am I missing? Any ideas on what my problem might be? Thanks

 

Sounds like air in the lines. Crank the injector lines at the injectors until it's squirting nice and hard.

 

Yes, 100% for sure.. If it won't fire off ether, then you aren't getting fuel / air in the lines.

 

Fill the filter with fuel first before bleeding/cranking, give it a head start

 

I got it going but I'm loosing fuel. I found out that it had an electric fuel pump that had lost connection. I ran it down the road and it didn't make it but a quarter of a mile before it died. I wiggled the wire and got it back running. If it's sitting and idling it'll stay running but when you start driving it looses fuel and dies. I'm thinking the electric pump is going bad. Thanks for the help. I'm sure I'll need more help in the future. Thanks again

 

Make sure when you put the new electric pump on you keep it metered at no higher than 7 lbs. If higher, you will blow the seals right out of the main fuel pump


Been there, done that

 

Does it matter that it's plumbed into the original pump or do I need to bypass it? I'm thinking it needs to be bypassed.

 

I always bypassed the mechanical pump on all of mine

 

Thanks for your help. I'll bypass the mechanical pump and check the pressure on the electric pump if it'll ever stop raining.

 

DO NOT use a cheap electric fuel pump. they don't last when used with diesel. if you are going to use a e-pump, use the facet duralift 40222 pump:

while it says 9 to 11.5 psi pressure, it will keep a constant 4-5 psi running.
the 40285 pump will drop down to close to 0 psi at full throttle.

 

Okay. I seen something on the Facet pump. I was wondering about the cheap pumps. Ive heard mixed reviews on them.

 

Never use a cheap pump with diesel. It will burn out. Diesel is thicker than gas or alcohol, and makes the impeller come loose

Usually when you are somewhere you're not supposed to be......

 

If you can afford the $100 faucet I would go to Napa and get a new mechanical pump. There only $30 and will outlast any similar priced electric pump.

The only benefit I can see to the electric pump is easy priming. Other than that I see no benefit and just one more connection to go bad.

 

i never got more than 5 years out of a mechanical pump. the facet in my 88 has been in it for 21 years now.

 

I agree, my mechanical pump is over 23 years old. They're just an old Carter gas engine fuel pump that's been around and used for decades back in the carb days.
