car wont start!!!

[GREASEMONKEY]

Are you sure its getting fuel at startup? This kinda sounds like the same problem i was having. I also replaced the CTS, Swapped Injectors, Checked ECU, ETC.. I never did figure out the problem but i was thinking about the MAS being the problem.

This also only happened when it was really cold out, Eventually i could get it running but i had to pull the plugs and pour a little gas down the cylinders and it would fire right up.

Start out by finding out whats the main issue IE: Fuel, Spark, Air Intake / Vacuum leaks. Then it might be a little easier to narrow it down.

that bastard started up the first try today!
weak battery and all!
what a bi*ch!
i will probably try to switch out the mas for another one i have....
so i am honestly lost at this point!
thanks though!


i guess when its below 0 degrees? gotta jump in the toyota instead!

the boost gauge is a big part of the car not starting.... now that it has warmed up, the car seems to not want to start again. again it will start whenever the boost gauge comes up to the zero, but if the boost gauge stays negative, the fuel relay will click right when i turn the ignition? and no fuel is what im guessing? my datalogger lost the mmcd program and i cant seem to find it online or have the know how of installing it back onto the pda? so i cant run the check engine light?

but as i said when the boost gauge is all the way negative the check engine light is on in the "on" position in the ignition....

but when the boost gauge is zero, the engine fires up right away, then kills, while it kills the fuel relay clicks?

i will try to get some vids posted soon..... i dont understand the boost gauge?

or if anyone has a logger that wants to swing by and give me a hand? i have some ice cold brew!

watch the boost gauge.....
comes up to almost zero but when cranking it goes negative.... doesnt start then just goes all the way negative...

as again the next try...
boost gauge at zero... this time cranking, boost gauge is positive..... car starts....

but it eventually dies and does the same thing as before, boost gauge goes all the way negative and check engine light comes on.....

well, when the car "started" how did it run? and how long? was it running well, or really choppy?

My car has similiar issues, I have no clue what it is, but I am switching over to a standalone system, so it doesn't matter anymore :)

it runs perfect when its running..... somedays it goes all day, and others not even for a minute?

Sounds like an ECU problem to me.
