then start it up! and the longer its been sitting without being started, the worse it is.For those of you who are not familiar with my car here's a quick spec lowdown.
.Rev3
1200cc inj's on top feed, external 044 pump, deadhead rail setup
stock head bar few polishings,valve springs etc
2.14L sleeved stroker bottom end
BMIC, side feed intake, q45 TB.
No lambda
-think this is closed loop? cannot remember which way around it.Linkplus g3 XLEM
560 bhp ish.
trying to start it yesterday after 6weeks sitting.
fuel pump primes, pressure 40psi ish. battery fully charged and power steering ecu disconnected for better cranking. Cranking for about 20 seconds, not even a cough! Pulled the plugs, all are black and drenched in fuel with the acception of no1 which is black and dry.
cleaned all plugs, dried bores, cranked engine with plugs out, refitted plugs, checked spark and all good. now 2nd attempt. Engine fires straight away but on 2 (intermittent 3) cyls. This is similar to what happens when the car has sat for about a week. 5 attempts later with added throttle and it would not maintain any idle without throttle it would just die completely.So.
.Plugs out yet again! two are warm, no1 cold
, no4 iirc not as warm as 2&3. all plugs tips are coked up again, so i cleaned them up yet again, dried the cylinders (lit splint down the plug holes). plugs back in, turn her over (this time with fuel pump off) and bam! fires straight up all cylinders and runs exactly as its supposed to. Quick flick of the fuel pump switch and it continues running without issue. one thing that did happen however and happens pretty much every time i start the car from cold (24 hours off or more), it cuts out after about 10 sec if i don't hold a 2k high idle on the pedal,but it does fire straight up again after and idle fine from then on.This is getting really annoying now, took me an hour to get the thing running yesterday and i absolutely stank of fuel after, had to have a shower! it always reaks of fuel when i first start it.
My theories are.
. possible Injectors sticking when cold? hence dry no#1 plug?
possible too much cold start enrichment
-would explain why i need to give it throttle if i stand any chance of it firing up?! -also blacking the plugs and causing fuel smell. However, it may not be too much enrichment, may be fuel pooling from trying to fire a stone cold engine with 1200's , causing a missfire. once two cycles of missfire have passed i could imagine there to be quite a lot of unburnt fuel in the cylinders giving a very very rich burn when it does fire - also causing black plugs and fuel smell.I am on the verge of getting rid of the car now because of these problems.
7 years of ownership and 6 years building the project and i still cant just get in it and use it! GRR!HELP!
