Angry no spark in coil after changing crank sensor

[shanebell2]

hi everyone i need help...... i just rebuild the front end after a smash all was working good now i just swapped out my old crank sensor with a eirlyer VN sensor it started real rough then stalled i tried the VN computer and it started then stalled and now even with my old crank sensor and VP computer the car wont turn over or even put a spark out of the coil pack...... plz help iam going mad

Check the Coilpack's wireing.. Is it grounded etc etc..

Was it in the car during the smash? It could be dead.

But first, is your battery connected? I've been caught on that one .. Ha ha ha!!

[shanebell2]

i have checked the wiring and the battery is connected lol just cant explain it ever since i replaced the crank sensor and had the issues it hasnt started

[Dum*P*ster]

the new CAS you put in.. It might be the wrong one.

What series is your engine? and what series is the CAS .. May be different,

another q, when you turn the key to start the car up.. does it crank? or just wind ..wind..wind etc?

If it doesnt do anything..Then something is wrong on the crankshaft line (Balaner->Shield->CAS)


[EDIT] - When I got my new CAS and Balancer.. I had to take my Road worthy cert to holden so they could get my Engine Number.. Old style Balancer and CAS is for engines under these number "127" at the start of the sequence. Anything above 127 is the new style .. Strange I know.. But, holden no what there on about this time.. ;p

yeah the 1 i put in was a diffrenbut i swapped the balancer etc over as well even the computer i have a series 2 engin but the sensor was from a season 1....... but the real weird part is i put in my old crank sensor and balancer back in and it wont fire...... o yeah and when i turn the key it winds eg the starter turns everything but theres no engin spark to fire it up

Hmm, check your Spark plugs and leads, they might be damaged..

But, i suggest if you can get a hold of a spare Coilpack & DFI give that a go.. DFI is the main ignition module.

Need more info again lol.

Do you let your Fuel Pump prime - Then turn the key?
Can you hear your Fuel Pump prime at all?
After you've tried to start the engine.. is there any smoke coming from the exhaust?
Is there any smells in the engine bay..Like oil or fuel?

EDIT - Also.. if you have a Gregorys manual or the Vn-vp manual book.. There is a guide in it on How-To test your Coil Pack with a multi meter, if you got acces to the book, have a look in it and see if its even getting any power to it

EDIT again lol - When you had the crash.. Did your engine stall ? or did you turn it off ?

[shanebell2]

the leads are fine the fuel pump is priming i even disconected it at the engin to check and fuel is all good after after to trying to start it it smells like fuel i dont know where to go after the coil pack but its not putting out ANY spark at all where should i go from there??

[Dum*P*ster]

Hmmm.. If you can get a hold of a known working coil pack and DFI.. swap it with yours,im betting your coilpack has shit it self

[shanebell2]

yup coil crapped out replaced it and all good now...... thanks for ya help...... now just to figure out the gear box LOL dam things spurting GB oil everytime its going

[Dum*P*ster]

You Your GB might need re-sealing

[shanebell2]
