06 F450 NO START HELP PLEASE

[skylinetowing]

I HAVE A 06 F450 IT CRANKS BUT WONT START. SPRAY A LITTLE STARTING FLUID AND IT WILL RUN. I HAVE REPLACE THE FICM, ICP, STC FITTING ON HPOP REPLACE THE DUMMY ORINGS. TESTED ICP I HAVE 0.80 VOLTS. DOES ANYONE HAVE ANY IDEAS???? GOING CRAZY I HAVE BEEN WORKING ON THIS FOR ALMOST A MONTH

What happened to it originally? Did it just die on you or did you mess with it and now it won't start?

I can't remember what .8 volts ICP translates to ICP pressure wise. I think it's right around 500 psi but not sure. Still sounds low to me. I guess you don't have any way to moniter ICP pressure with a scan tool? Have you tried pressure testing the high pressure oil system?

Have you tried replacing the IPR?

[skylinetowing]

Did a engine swap. .8 volts from the icp means 500 psi I had over 1volt. I have vcm scan tool.it was showing good oil pressure did air test couldn't find a leak

Gotcha. No exhaust smoke of any kind? How much of an engine swap? Entire engine, short block, long block? Are they your original injectors? Is it logging any codes?

I assume when you say you get it to run off ether it just starts up for a couple seconds then dies off?

[justinmix]

Never mind, looked over your other posts and saw that is stays running after you spray it.

Does it do this only when it's hot? Will it start if totally cool? When it does the no start, you're showing over 1 volt at the ICP sensor? Have you tried starting it with the ICP sensor unplugged?

glow plugs maybe??? simple to check if they have power and correct resistance.

[justinmix]

Not a bad thing to check out, just to make sure they're working. On an 06 truck it should log you codes for this, right down to individual glow plug faults. Not sure if he has checked codes or has any codes though.....

not familiar with 06 but between my 05 and former 03 have run over 200,000 miles with 1 check engine light for 2 days.the 03 in particular i could have in the shop weekly for major work without ever seeing a light

06's will throw engine lights more then earlier years. Due to emissions regulations they throw a check engine light for anything emmisions related, like glow plug and EGR issues. If even 1 glow plug is out on an 06 truck it will throw the check engine light. In a nutshell, burnt out glow plugs will make excessive smoke on startup, so it's an emissions issue.

This is also why if you do an EGR delete on an 06 up truck you need a programmer, otherwise it throws the check engine light for low EGR flow. Earlier year trucks throw the same codes, the just don't illuminate the check engine light.
