Rb20det No Start After Head

[svarl]

heya.

how is all just wondering i just finished doing a head on my r32skyline the head was serviced and had the 12 bent exhaust valves replaced done by fhyswick heads when i put it back together all wiring is on all vacuums are on all intercooler pipes are on and everything is tight when i tried starting it it pops and cranks but dsnt fire it has injector pulse, has fuel pressure has fuel flow, and has spark.

what im wondering if anybody has had this problem before and has any advice on what it can be any helpfull comments will be highly apprecieated it has been sitting for a couple of months now so do u think its worth while taking the plugs out and skirt some oil down the bores? also when i took the plugs out they didnt have any fuel on them? and it has pressure, flow and pulse.

thanks mark hope to hear back soon

check compression / cam belt timing = cas wrong and no compression

Getting any error codes from the ECU?

oh i dunno never thought to plug the scan tool on lol when i was trying to crank it b4 it went KABANG straight out the exhaust so timing is out somehwere all coils are going to right place and i have all the wiring on the back of them right i drew a map b4 i took it all apart lol.

but would timing out cause the plugs to be dry when i take them out? it sounds like it has compression somewhere but dont have a compression tester to check. i also know there is one blue connecter under the collector assembly that i couldnt find to anything its right under the throttle body and just above the fuel rail.

also noticed the CAS has left to right adjust ment could that be cuase it if thats wrong?

Has the locating tag for the CAS on the end of the ex cam broken off? Sounds like the CAS is out of whack a bit.

had a look my exhaust cam nvr had a locating tang?

also the exhaust cam looks out a tooth so will redo that and will havta see if i can find a way to re align the cas again..

any idea what tht blue wiring connector could be?

CAS should have been marked when removed and put back exactly to same position (usually neutral position in dead center), in the wrong position can do nasty things like advancing the base timing (to the left) or retarding the base timing (to the right).. (if i remember left to right correctly). Timing will need to be checked each time the CAS is taken off.

You should be able to see where the tag broke off. Now all you need to do is visualise how the CAS would have aligned. The CAS also has a set of teeth to locate on the ex cam. By the sound of it, you are 1 tooth out on the CAS mounting position.

heya thanks all yea the exh cam is out by a tooth so when i get a puller to get the crank pulley of will put that back a tooth and get the cas on right cranking it one tooth out shoulnd effect the vavles should it? any ides on the connector will try get a pic of it im guessing the bang out the exuast was cause it was to advnced on the exhaust stroke?

heya guys got the 32 running today but the head seems heaps noisy like as in the cams are to tight i mean they did feel pretty tight when turning it over but didnt think much off it how tight are they cams suppose to feel? also its running pretty rough on start up what are some things i can check that would cause that after doing a head?

thanks mark

Check that you tourqed the cams to the head properly...

What did you tourqe them to?

[svarl]

i dunno the head shop did the entire head inch reassembling the cams could the shim adjustment be out at all?
