Powerchoke wont start.

So my 99 stroker was having a hard time starting this morning. It would start up difficaultly and rev. up all the way and just cut out and shut down. It blew alot of white smoke out the exhaust. So i went through everything, checked all the fuses and all the connections again and again and still nothing. Then i just went and bought a new CPS and replaced that and now it wont even start at all, it just cranks. So I am currently charging the batteries and have the block heater plugged in. Does anyone have any other suggestions that i could try. Please help asap im supposed to leave on a trip tommorrow. THANKS

i thought it would have been the CPS because it has never been replaced and i have 63k on the truck. But that didnt work. Im hoping its just low on voltage. I have tried playing with both my chips. I have the ATS chip that can be turned off and i have a six stage injector pressure module that can also be turned off. Doesnt matter what position any of them are in, it still wont start.

I would start by unhooking your chip and the injector pressure control module not just turn them off, if a chip is loose it will cause a no start, and if your control module is malfunctioning who knows what it would do.

OK. i will try doing that stuff. I have not got it started yet. I ordered another CPS because i think its that, and you can always use a spare. My rpm's dont move when i crank the motor, so i have read that that is a cause of the CPS. So i will try both of those and let you know.

Nothing yet. I just barely put in the new sensor. i got the original oem instead of the POS autozone one. I tried starting it and still nothing.
I disconnected the injector module but havent done the chip yet because that ones a little difficault.
Im way low on voltage (11.0) becasue ive tried starting it so many times.
So im letting it sit overnight charging and will try again in the morning.
Plus its way flipping cold here and i have a foot of snow. Hard to work on the truck when its only 10 degrees outside.
thanks and will let you all know tom.
Does anyone know if the vacuum system has anything to do with the motor starting? i noticed one of my hoses has been burnt off. Got a little to hot.
What are all the esscential components for it to start?

Theres obviously fuel, oil, air, CPS sensor.
Should i be checking injector regualor, injector pressure sensor, all that bs.
does than MAP sensor play a part?
help me out.
thanks

k....try this....

check your glow plug relay...there are instructions in the tech files....do this and try to start it first..... this is the most likely culprate, although the lack of tach signal is throwing me for a loop. could have been a bad CPS but it should not have blown any smoke becuase it should not have injected any fuel if the aftermarket CPS was no good

other possiblilities....
under valve cover harnesses
bad glow plugs
bad injectors (unlikely for enough to fail at once to cause a no start on a well maintained motor though)
unplug your fuel heater.. it could be shorted
Check your fuses
