Hard Starting Issue

Truck starts hard after sitting for more than just overnight. It will start after first turn over and idle for a second then die. Then it has to crank for 5-10 seconds before starting. Once running, all is well. Idles good, runs good, doesn't seem to be any power loss. I just ordered an AutoEnginuity and would like a little guidance where to start testing aside from just pulling codes.

Thanks guys.

Have you replaced fuel filters and checked fuel pressure yet? I'm betting you have a fuel pressure issue, possibly with the HFCM itself.......

FICM is good. 47-48.5 constantly.
Batteries are brand new.

How do you do HPOP-Air test?

IPR-Voltage test?

Ignition System test?

Hard Starting Issue

Hooked up a fuel pressure gauge this morning. With the key on and fuel pump running (20 secs) pressure rises to about 40PSI. Fuel pump shuts down and pressure immediately drops to zero.

No leaks that I can find.

Fuel pump?

get the blue spring update and install. Replace both fuel filters. Then if pressure still not up to 60-65 psi with key on, replace the pump. Only other possibility is the pick up tube is plugged in the tank. Not likely, unless you have a metal fuel tank. they are notorious for the inside lining to flake off. Stick your head down there and verify you have a plastic tank for peace of mind....

You can save some cash by just buying the Racor fuel pump itself, that inserts in the HFCM. There's a guy on Ebay selling them now, around $180.

Already have the blue spring installed.

Just check fuel tank and it is NOT metal.

I'll check out the pumps.

Thanks.

So I replaced the fuel pump and both filters. At idle I am now seeing about 55 PSI.

Here is a link to a video of what my fuel pressure does when I turn the key on then starting the truck. This doesn't seem right.

55 is acceptable......anything under 45 is a risk to your injectors. With a blue spring and new filters, I would expect to see 60-70 psi. Possibility your pump is getting weak, but still within specs.

It's normal when you turn your key on, it will build pressure.....if you don't start the truck after a certain amount of time, the pressure will bleed back to zero. If you have 55 psi, and it stays there while driving, you're okay and good to go.

Did you do the blue spring yourself? If not, you better take a look and verify it's a blue one. Sure acts like the original one......
