If i have not started the car for a couple of weeks it becomes a right mission to get the thing back alive! its like i have to bring it back from the dead first
then![](./images/smilies/spacer.gif)
start it up! and the longer its been sitting without being started, the worse it is.

No lambda

-think this is closed loop? cannot remember which way around it.

Linkplus g3 XLEM
560 bhp ish.
![](./images/smilies/spacer.gif)
trying to start it yesterday after 6weeks sitting.
![](./images/smilies/spacer.gif)
fuel pump primes, pressure 40psi ish.
![](./images/smilies/spacer.gif)
battery fully charged and power steering ecu disconnected for better cranking.
![](./images/smilies/spacer.gif)
Cranking for about 20 seconds, not even a cough!
![](./images/smilies/spacer.gif)
Pulled the plugs, all are black and drenched in fuel with the acception of no1 which is black and dry.
![](./images/smilies/spacer.gif)
cleaned all plugs, dried bores, cranked engine with plugs out, refitted plugs, checked spark and all good.
![](./images/smilies/spacer.gif)
now 2nd attempt.
![](./images/smilies/spacer.gif)
Engine fires straight away but on 2
![](./images/smilies/spacer.gif)
(intermittent 3) cyls.
![](./images/smilies/spacer.gif)
This is similar to what happens when the car has sat for about a week.
![](./images/smilies/spacer.gif)
5 attempts later with added throttle and it would not maintain any idle without throttle it would just die completely.
![](./images/smilies/spacer.gif)
So.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
Plugs out yet again! two are warm, no1 cold
![](./images/smilies/spacer.gif)
, no4 iirc not as warm as 2&3.
![](./images/smilies/spacer.gif)
all plugs tips are coked up again, so i cleaned them up yet again, dried the cylinders
![](./images/smilies/spacer.gif)
(lit splint down the plug holes).
![](./images/smilies/spacer.gif)
plugs back in, turn her over
![](./images/smilies/spacer.gif)
(this time with fuel pump off) and bam! fires straight up all cylinders and runs exactly as its supposed to.
![](./images/smilies/spacer.gif)
Quick flick of the fuel pump switch and it continues running without issue.
![](./images/smilies/spacer.gif)
one thing that did happen however and happens pretty much every time i start the car from cold
![](./images/smilies/spacer.gif)
(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.
![](./images/smilies/spacer.gif)
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.
![](./images/smilies/spacer.gif)
My theories are.
![](./images/smilies/spacer.gif)
.
![](./images/smilies/spacer.gif)
possible Injectors sticking when cold? hence dry no#1 plug?
![](./images/smilies/spacer.gif)
possible too much cold start enrichment
![](./images/smilies/spacer.gif)
-would explain why i need to give it throttle if i stand any chance of it firing up?!
![](./images/smilies/spacer.gif)
-also blacking the plugs and causing fuel smell.
![](./images/smilies/spacer.gif)
However, it may not be too much enrichment, may be fuel pooling from trying to fire a stone cold engine with 1200's
![](./images/smilies/spacer.gif)
, causing a missfire.
![](./images/smilies/spacer.gif)
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
![](./images/smilies/spacer.gif)
- also causing black plugs and fuel smell.
![](./images/smilies/spacer.gif)
I am on the verge of getting rid of the car now because of these problems.
![](./images/smilies/spacer.gif)
7 years of ownership and 6 years building the project and i still cant just get in it and use it! GRR!
![](./images/smilies/spacer.gif)
HELP!
