wen i turn the key...she cranks....starts for a second then cuts right off...if i try to crank it and give it gas...itll rev...then cut right off soon as i take my foot off the gas...i dont c any vac leaks...i dont kno what the problem is...im fed up

 

You know in order for you to recieve help..we need to recieve details and information that you didn't specify.

-What Car?
-What Engine?
-Did this just start happening one day or what?
-You say your fed up..so I assume you have been messing with it for awhile now..what have you checked so far?
-CEL?

Details man...details....

 

eg hatch...
b16 head...gsr block type r intake mani...
cel 41
i just put it together and just put it in the car ...
tried to start it a few times...nothing...

 

Code 41 is an O2 Sensor if I remember correctly. But a bad O2 Sensor won't keep the engine from starting.

-Is the Fuel Pump priming when you turn the ignition switch to slot 2?
-Since you just put this engine in..Check all your main underhood grounds(Valve Cover to Radiator Support, Tranny, Thermostat Housing)
-The engine needs 3 componets to run(Fuel, Spark, Air as I am sure you already know) so make sure your getting those, Of course Air is the least likely to be an issue.

If your only getting the 41 CEL Code then your other wiring should be good. I am not that good at diagnosing problems so if I think of something else i'll holla at you.

 

i got it started....but now it starts off really slow then after a few seconds the idle speeds up....dunno what that is....HELP!

 

im also getting cel 14....i cleaned the **** and changed it....still getting the code...

 

check fuel pressure, at the rail, if you can check injector duty cycles.

 

how long ago did you put that engine togeather? cause if its new that might be the problem.. you also might need a tune cause of the mani and the new head

 

Is the mechanical timing of the cam and crank off by a tooth on the timing belt?

 

Their is Actually 4 Things a engine needs to run, 1-Compression 2-Spark 3-Fuel 4-Timing and no **** air. you need to check compression and see if your sealing that head good. and make sure what ecu you should be running with that combo.

 

just did it last week...its nothing special...stock gsr block....b16 head...skunk 2 valves....dual springs n retainers...type r manifold...b&m fpr....nothin special...

 

this is what scares me the most...that belt has too much play in it....ive redone this process like 5 times....belt will not get tight enough to where im not nervous...

 

ok will do....just out of curiousity....whats the aebs headstud torque spec....any1 know
