long story short just finished putting in my new shortblock from forged first day breaking in motor CEL marks a bad cam sensor same time i replace it and purge my clutch felt really hard.... pivot ball breaks hence i cannot start my car up to check the sensor..... after replacing pivot ball i reset the ecu doing the technosquare instructions and car wont start at all just cranks ..... i will be running test tomorrow but wanted to see if you guys had any input on this


dam still was a long story


ANY HELP WOULD BE GREAT THANKS

 

could be anything really, from improper motor assembly to cut wires to bad fuel pressure.

good luck

 

fuel pressure maybe ima check that in da morn and also my spark

 

check the ground on the front of the motor

 

checked the ground even added more grounding just in case ........... ok ran some test seems to be the connector to the bank 1 sensor on my passenger side...... car started after moving or playing around with the connector

it turned on stayed on drove around and then when i stoped turned the car of it wouldnt start again......

dumb founded now i dont knwo what to do any help

thanks

 

post all the CEL codes.

 

Flywheel not installed correctly!!!

 

we thought of the flywheel but i drove the car for like two days..... unless it can still if its installed backwards i dunno i dont think so but let me know ..... from when driving it around to changing my pivot ball i didnt touch the flywheel and the car turned on and drove fine for a bit just last night soooooo ahhhh .....

 

codes are p0340 and p0335 which is crannk sensor and cam sensor bank 1 i replaced the passenger sensor and crank sensor and still notthing

 

sometimes the codes for sensors don't display if engine is not running. often if one senor is dead the others die too. so maybe swap the other cam sensor too. and check signal plate on flywheel. it might just be tiny partial parts missing...

 

sounds like the flywheel was put on wrong

 

im replacing the other cam sensor in the morn but jtran wouldnt the car not start at all if it was put on wrong ...... dam these lil setbacks i was suppose to have my motor broken in by now and would have gone to tune with you this weekend oh well minor setbacks gotta do it right

 

Hope you figure it out soon bldg. I'm suppose to re-tune aswell when you take your car to "JT". Maybe, the flywheel is wrong and that is what was causing the vibration you had mentioned. Hate to drop that tranny again.

 

well it can start anyway, if 2 of 3 sensors are good, but in limp mode

 

car still will start with the flywheel put on wrong. on the flywheel there is a place on the flywheel where it lines up with a place on the crank. i would check that first.

 

check/replace flywheel sensor sounds sort of like the problem i have experienced before on my Z

 

Dropping Tranny Saturday to check the flywheel. Hopefully we find something wrong.

 

i hope so drock we'll see!

 

ok guys update please help me diagnose the problem!!!!!

Rule Out ( things Checked and working)

Flywheel Positioning Correct
all sensors associated with tranny in checck
all sensors and grounding wires in tact.
new cam shaft sensors and crank sensor

ONE PROBLEM ..... NO CONTINUING SPARK OR FIRE

Car Cranks sets of one spark and then dies...... will repeat as long as i pull the key and retry....

theories:

aftermarket car alarm
anti theft system
or some type of grounding issue
computer??????
i dont know what to do next please if anyone has any ideas or troubleshoots let me know

ive tried reseting the anti theft according to manual but no luck so far

 

Just a little more clarification:

1) Car cranks perfectly fine but won't start.
2) As the car is cranking fuel pressure seems normal. Fuel pump is working.
3) Checked spark while cranking. While cranking it'l only spark "once". If you keep cranking you won't see anymore spark ecxept that one time.
4) Flywheel positioning correct.

Could it be:

Ignition "brain" (I forget what its called)
Key fob gone bad
vehicle's antitheft
Aftermarket alarm

I think the main thing is what can be causing no continous spark.

Sometimes while you are cranking the car it sounds like it wants to turn on but then it doesn't and keeps cranking.

Thanks,
