I've got it all back together, and it seems to run OK, but it's hard to start. If I give it some throttle, it will fire up in 4 or 5 seconds. But without any throttle, I have to crank it for 20 or 30 seconds or more before it will fire up. When it does fire up, I get a short puff of dark gray smoke, then no haze at all. It just feels like it's loosing prime. At first I thought it was just air in the fuel, but aftter running for 15 minutes or so, I just don't think so.

The fuel pump, filters, overflow valve and injectors are all new. I have 15-18 psi fuel pressure at idle. Just about all of the fuel lines are new too.

Anybody have any ideas?

 

mine does the same thing after i bumped my timing. not sure if your timing was at 16 before or not. jusy my 2 cents

 

what are the pop pressures on the injectors?

it sounds normal to me, ever since I went with bigger injectors with a higher pop press I had to give her a little " love tap" to start

 

May be that the fuel solenoid isnt fully engaging. Try holding it up while you crank and see if that helps.

 

I didn't think that was much of an issue until you got over 16. It was one of the reasons I didn't go higher with the timing.


?

They have a 280 bar pop.


That was one of the first things I check, all good there, I had already put in a fresh relay as part of the rebuild.

From what I'm hearing, it's sounds like it's the price you pay for performance. Glad I put new contacts in the starter while it was apart.

The main thing is that the truck has autostart, and I really like that in the winter. But it will never start with that now. Guess I'll rig up a fast idle setup and see if that will work with the autostart.
