not. even. trying.

that's why i'm thinking it is still air locked, or some other 'simple' issue.

RPM, ICP, Fuel delivery (firing). That's all.

It should at least stumble if there is a problem with programming for injectors, a bad injector install, etc.

Does your tailpipe smell like diesel fuel? Any smoke while you crank?

Where are you located? Maybe someone nearby has AE and can help monitor some of the numbers while cranking?

Ah...good.

Can you give us a rundown then while cranking in AE:

RPM
ICP
Battery Voltage
FIPW
ICP DC%


I *believe* (but haven't confirmed) that if FIPW is Zero, the injectors aren't firing. I don't know another PID to check it?

If the top 3 are in the Green (values, not in AE), then you should have FIPW.

I also think that if FIPW is showing, but no fire or fuel out the tailpipe, then you have a fueling issue (filters, pickup lines, fuel rail lines, etc)

Did you reply about any smell in the tailpipe or smoke and what color?

(I was out prepping the garage, moving stuff around for this week's project work)

Everything I've read here still only shows 270 ICP. Has to be 500. Keep cranking or start testing HP system.

You're probably right. I was looking to be definitive on the RPMs, too, so we are looking at only one system holding him back

I may be in the garage when you're back on, heading back there right after some lunch.

Let's assume this is an o-ring issue...what's the likelyhood that i can pop the valve cover and see which one is blown out by cranking it?

The Cody test is the easiest way to check for a bad injector o-ring. If you have an oil rail crossover, remove it, if not just pull a oil rail plug and use a air nozzle with a rubber tip wrap a rag around it and put pressure into the oil rail and hold it for a minute or two. listen for gurgling. If you don't hear any go to the other side.

Wrap the nozzle with a rag or when you remove the nozzle from the hole you will get covered in oil.

I had a no start about 6 months after installing new injectors, only building 250 psi, and that is what it ended up being.

I put the IPR sensor ln backwards after repairing the IPOP. Kinda stupid but the result is it wouldn't fire at all. Put back on correctly and it fired right up.

You mean the coil or the needle valve? In my head, I'm seeing a tinnerman nut being jammed into the IPR hole on the HPOP... and that can't be right.

Oh crap..... Doesn't the IPR and the EBPV have the same connector?

They do, but the wires aren't long enough to reach the other connector.
