have you tried cleaning the maf ? i know those thing are sensitive one time my car was driving like crap and throwing CEL because of maf.

 

at least yours cranks marcelo......my just turns over

 

on my way to julios.. there gonna take my MAF out and put it on ur shiiiet and see what happens.. :O

 

yo CHAD make sure its on the right way! meaning the air flow arrow is pointed towards the throttle body. and take a picture of my engine bay and send it to me at m.cederna@gmail.com i told luiggi lst night but he wasnt at julio's. let me know wuz up! i still dont think its the maf sensor. i'll cross my fingers! gingles whats up with your car?

 

no clue yet.....i dont think the spark is strong enough.....i went back to just one step colder plugs and tried but nothing so im gonna look at the wiring diagram here in a second for the coils to make sure i didnt miss a ground.......the engine just sits there and turns over...and over....and over.....my battery died so i put it on the charger and am gonna go back out later to try....its freakin 95 degrees outside and i have no shade.

 

try what ptuning said go to stock plugs and the pedal to the floor

 

yea im gettin ready to head up and buy some stock plugs real quick and try it....i know im getting spark though but not sure how strong it is...........looks like were racing to get running first man.......5 dolla says i win

 

also....how are they going about breaking it in....my roommate said once it cranks let it sit around 3k rpm for a few minutes to seat the piston rings and then just let it warm all the way up....after that cut it off and check coolant.......let it cool all the way back down and start it up again and start the driving break in.

 

well luiggi is gonna drive my car and tune it conservative and safe to just break in the car. he said around 1200 miles to break in but make sure i fluctuate the speed not to stay at a steady speed. and hit a lil boost not full boost. after 1200 miles 18-20 psi here i come! and i bet you 10 you will win also in driving your car then me.

 

well i know what my problem is.....i forgot to plug in my knock sensor........now i have to take off my dang intake mani to get it....but im waiting untill it gets below 100 degrees to do it..........as soon as my car is running and i put around 500 miles on it i have a 2100 mile road trip ahead of me......im moving to colorado this week. i pray it holds up haha.....ill probably have to retune it by the time i hit kansas because of the elevation difference.......oh about the engine break in.....like im confused about what to do......should i just crank it up and drive it like normal or should i do the 3k rpm for a few minutes?

 

your moving to colorado where abouts? well will have to meet up check out your car let me know kinda excited to have a new boosted scion in the state

 

marcelo they already tried the stock plugs with gas to the floor so Toan any more suggestions?

 

changing to your maf didnt work either?

 

Are you sure you have adequate spark?? What size injectors are you running??? Are you sure the injector pulse setup is correct in the tune??? What all is not stock??? Does the motor (I know its built) have adequate compression?? Maybe the rings are misaligned/incorrect/etc. (like aligning the openings together lolz). There are so many questions I could ask haha.

 

Also, would it start up then die, or just crank over??

 

yea cory im fixin to move to the lakewood area.....where you located?

 

Im in arvada about 20 mins north of lakehood wat are the cross streets

 

It will start and then die. I have 550cc injectors. The motor will be disassembled again since can't find the problem. The tune is the same as before all I know is the injector pulse is really high? It sounds like it's flooded and smells like fuel and injectors are soake in fuel.

 

hmm when i was there it wouldnt even turn on

 

Marcelo - I was going to suggest gingle's problem - check the knock sensor.
