help

[dstmsp03]

ok, just put the forged built motor in the car, set everything to time, checked all grounds and just replaced the crank sensor. the car just rolls and doesnt start. getting plenty of fuel and spark. whats wrong here? really need help

[Witchdoktor]

similar situation happened to someone on another forum. timing belt wasn't installed right, timing was off.

[dstmsp03]

We've checked that. plus I don't think its the ecu, its getting spark... could it be the cam sensor?

[Witchdoktor]

did it work before? any reason to think it broke? all other sensors are plugged in and even if the engine wasn't primed I'd still think it would turn over. hope whatever it is you figure it out soon.

[dstmsp03]

yeah it did, car ran good until the motor blew.. C'mon ppl, really need my car quick.. What all can this be?

[ForceFed]

If your getting spark....and fual..Its got to be in the timing..you better recheck that timing belt and make sure its on properly.

Is it firing at all...Even backfiring....If there was fuel...and spark..It should ignite at somepoint even if its a backfire?
Did you purge the air from the fuel lies after having this all apart?

[dstmsp03]

yes, it was purged, there is nothing.. It just rolls..

[ForceFed]

Is there fuel though?
to and from the injectors?

If so..I would SERIOUSLY check the timing belt.
You sure you didnt install it 180 out?

[dstmsp03]

yes, fuel to and from the injectors, I will recheck time.. I know the timing arrows point in on the cams and up on the crank.

[ForceFed]

IIRC...cant you put the cam wheels on the wrong cam and they will be 180 out when lined up?

Someone else will have to answer this..but I thought when I looked at them..It was possibble.

[dstmsp03]

never took the cam gears off when we took it apart.. pulled the whole cam.. with gear attached..
that would make it 180 out.. but i know thats not the problem..

[dstmsp03]

ITS ALIVE.. haha.. turns out previous owner must have had the cam gears out, they didnt line up at all with the movement of the valves, fixed that, redid timing, and she fired right up!.. thanks for the help all!

[Witchdoktor]

nice

[dstmsp03]

yeah, it was a bitch to get into time b.c of that issue! but it sounds mean as hell now with the 2871, 626 mani and 8.5:1.. now just to get my computer to connect to the ss that i just installed today!

[SeR_Cyclops]

man you will have to post back up and tell us how she runs! vids and pics also!!

[dstmsp03]

def... just im at work right now, but my cousin is finishing putting it together, then tomorrow its off to get an allignment, i am hoping i can get the ss issues solved here pretty soon.

[dstmsp03]

another issue, my boost gauge isnt reading anything in Vac at idle, just 0, its showing 10 psi when its driving and boosting..

[2.0t03speed]

i wouldnt be boosting it at all if this motor is brand new

[dstmsp03]

break in on a built motor is to run the piss outta it..

[2.0t03speed]

umm what? thats not how i learned but to each is own break in your motor how you see fit

[SeR_Cyclops]

i have never heard this either.

i had my second built motor now and my mechanic said take it easy and dont run fully syntheitc till 3000 miles on the new motor..and hes a mazdaspeed specialist

[dstmsp03]

i am not running synthetic til the second oil change, and we were testing to see how the boost and vac is,.. back on topic, what can be the cause of no vac and reading 10 psi boost?? we replaced all vacuum lines today!

[terbow]

if u have no vac it should be idleing like utter shit or reving itself like knightriders car

if its idleing fine and ur not idleing at 3k rpm. try another gauge or check the boost reference.

[dstmsp03]

the only prob i am seeing with idle is when it comes to a stop, then it shuts off unless you pop into nuetral and feather the pedal...

[terbow]

yea thats usualy a leak post maf. like if u have a bov and no recirc.

id check the gauge or its source.

[brmiley]

im telling you check your egr valve...

they most of the time just need to be cleaned.

[dstmsp03]

egr is brand new
