R33 Not Starting,

[nickperth]

Hey hows it going i got a R33 Series 2 which can not start, it cranks over but it wont start, it aint sputtering so it wouldnt be a fuel issue, but im thinking it could be down to the spark. The car originally had broken down while driving so i had to get it towed back home. The things i have currently done to the car is a ecu diagnostics check and it came up with 55 so everything is fine according to the ecu. I also chectked the spark plugs and did notice a very small amount of oil on the spark plug i only removed the first 3 spark plugs.

I did check the cables of the distrubator and everything seems fine, i However recently hit a pot hole and had probably caused to dislodge a gasket or something and its been losing a bit of oil latetly which has caused the oil level to go down and has caused a very noticeable amount of oil on the left side of the engine just under the turbo, so im not sure if this has anything to do with it. I also have also started to experience a bit of oil in the inlet system more then i used to, infect i used to not experience any oil.

The main thing i want to know is there any tips were you can guide me what i should do next to see if i can resolve the problem, or a possible sympton that usually causes problems like mine as i have had done a search on the forums and couldn't find anything.

Yours Truly,

Nick

Ive just checked the CAS and its working all good as i hear the injectors when i turn the wheel on it, so its no the CAS.

Hi i would be checking the turbo feed line incase it might be cracked or the oil return lines to the sump from the turbo and cylinder head

also check rocker cover bolts.There is not much else there unless you have damaged your sump remove the heat sheilds over your tubo

and it should give you a better inspection.

With your engine not firing it could still be your fuel pump or your crank angle sensor check to see if your fuel line pressurises then the ignition

is switched on and that you also hear the pump prime up.

[nickperth]

Alright cheers ill have a look at it tomorrow morning

[nickperth]

Ive done the fuel check on the pump and i can hear it prime and ive taken the fuel hose off and gave it a crank and fuel started coming it out. I took of the crank angle sensor and turned the wheel and could hear the injectors going so id say its not that as well.

How would i go by checking the spark and coil packs to know if the problem is a spark related issue?

[DVS JEZ]

Pull a coilpack out of the bracket. Plug it in to the loom. Fit a spark plug to the coilpack. Rest the hex of the spark plug against an earth (something metal) and crank. See if the spark plug has a strong arc.

Can u explain more.

Did it stall and now won't start? If so what exactly happened when it stalled?

[nickperth]

When it stalled it happened when i engaged the clutch so i thought it would it start up when i disengage it, but it didnt. So i tried cranking it and it kept turning over but it didnt sound like it was spluttering so i was thinking it would be spluttering if it was fuel, if it wasn't most likely something like a ignition or spark problem.

The spark plugs it currently has a brand new Bosch Iridium ones which are gapped at 1.0mm they been working perfectly fine so far i did however check the and they look perfectly fine for something thats been in the car for the past 300ks.

I am however getting a set of coil packs for a series 2 this week and possibly going to change them over to see if its down to the coil packs.

I will try today the spark plug problem and give it a show if its down to the spark

[nickperth]

I just want to add i did change the fuel filter just to make sure it wasnt blocked but i got admit when i cranked it over you can here a slight bit of sputtering coming from the exhaust.

[nickperth]

Also when i took the fuel filter off there was no fuel delivery but i could hear the fuel pump priming

[nickperth]

Okay i got the car started i changed the ecu over, however the car now is running quite rich it blows black smoke, i however am having a very rough idle issue it sounds like a really lumpy 69 camero but it sounds like its struggling to stay on and its reving at about 800 rpm, i also get this ticking sound from the turbo and exhaust manifold area.

Would you possibly know what the cause of this could be, im guessing it could be a fuel relay. However i did check the injectors and the only one didnt seem to change in idle was first injector not sure which one it is but its the first one when looking from the front.

However all the others changed when i took the plug out except for that one.

How long did you run it for could be a build up of fuel in the cylinders correct me if I'm wrong. Ticking sound could be a small exhaust leak check to see if all the studs are still there and gaskets are in good condition

[nickperth]

I ran it for a good 10minuets, ill reset the fuel pump tomorrow and ill also check the leak i think it could be i need some new studs, as i recently replaced the exhaust gasket. Though the rough idle im sort of worried about it, its quite rough its i got to admit, its a strong vibration, like it would sound awesome in a muscle car not so cool in an import

[DVS JEZ]

Check all the intercooler pipes and connected and tight

Try some new cheap copper spark plugs. Bkr6e.

[nickperth]

Okay car aint running rough any more i replaced the exhaust manifold head studs as i saw a bit of carbon build up so ive replaced them however i took the car out for a short drive today and its back firing real bad and its struggling to boost up, however it broke down after 5 minuets again same problem it wont crank over, would you guys were i could check next.

[PaulosECR33]

when you pulled your plugs out are u sure it was oil and not fuel... cos if you say its running quite rich and missing you could have fouled plugs

+1 on getting new plugs
