No fuel to the injectors?

[3bals]

I stopped by the shop today to drop off the custom brackets to relocate the FFM. They had everything hooked up and were trying to get it to fire, but couldn't get fuel to the injectors.

I figured it would be a hard start with everything new. New IP, new FFM, new injectors and new injector lines. I had them plug in a different (new) PMD with a new ext harness and still no fuel. Both my PMDs are Heath's. We have fuel to the IP and the air is out of the FFM.

Any thoughts?

Have them pull the glows and crack the injector lines while they crank it. It will turn over much faster and easier with no compression and the fuel won't be trying to expel compressed air in the fuel system. once they get fuel to the injectors reassemble and fire it up

I'll tell them, thanks.

I sent a message to have them try that and I got a call that it was running. Apparently they just didn't try hard enough the first time. I'm headed over there now to hear it run.

Sweet! Pics are good but video is better

Hopefully you don't need a new starter. Hope it runs well for you.

Well, the starter was new before today.

I'll get video and sound later, too much going on today.

Sounds good though

Here's what I think happened today.

Both times I have replaced an IP and injectors, I tightened down the injector lines, bled the FFM and cranked it up. It always took some effort, but not too bad.

The tech that was working on the motorhome, had all the injector lines loose and was looking for fuel to be coming out. As he tightened them down finger tight, one by one, he soon was showing some fuel. He tightened them all down and it started.

The main thing is I panicked, having been waiting months and spending thousands, all kinds of things went through my head.

As long as the @$%^& galley plugs are tight and oil isn't running down the back of the motor behind the flex plate, its pretty easy peasy to sort out the fuel issues. We started my new motor with a slight squirt of 5/30 weight down each intake channel. It lit on the fumes, stank like hell, and helped shorten the number of crank intervals trying to bleed the air out of the lines like I had with an IP swap. I like the idea AK brought up of spinning the sucker with the GPs out until diesel mist is in the air better though (Missy Goodwench's "new engine start sticky' IIRC).

Important thing is "IT IS ALIVE!"
