the engine start for a second and stop , start /stop start / stop ............
check with scangauge and all the values seem to be ok .
I connected the scangauge in my other truck and the values are pretty same .
Tried a new cam sensor and nothing .
please help thanks so much

 

Say again?

Truck starts and dies on it's own? How long does it run? I think help would be more forthcoming with a better description and an idea of what PIDs you are checking and what their values are.

 

ficm 49v
icp 500 plus
ficm 11v
ipr 15
those values are similar tham my other truvk that run ok.
i started today after many tries , and it wont idle, I have to keep my foot on the acc pedal ,

 

What are the ICPV's at KOEO?

 

icp more than 500

 

Check fuel pressure ?

if it starts but wont stay running and all vitals you mentioned were ok that is what i would check next.

 

Check ICPV's (ICPV's = ICP Volts) at KOEO (KOEO = Key On Engine Off)

This checks your ICP sensor

.

 

KOEO:

ICP psi
ICP volts
IPR
Map
Baro
EBP
FICM main

it start with carbuartor cleaner , and no idle .

 

does the oil filter must be full?
I just remove the oil filter and it was empty , I dont know if that is normal .

 

When you open up the oil filter, there is a drain that let's the oil run back to the oil pan.
