Vr4 Issues

[Guest]

Hi guys, calling all gurus here please..
have my old purple vr4 in my shop running Map2 Ecu and moved it outside today.
Went to move it back inside and it would not start, just kept swinging..
always ran like a dog with the map Ecu tho but this time nothing.just turns and turns.
so begin elimination process.

rewire factory Ecu back in
connect afm
Remove cam covers,check tdc all still good
check voltage on coils, all ggood
check fuel pump operates by looping direct,all good
petrol smell from exhaust so fuel is tthere
swap out ifs
replace inner cabin relays

and still no go..

all lights are ok
abs however not lighting up, possible issue?

failing the scan for fault is there anything you guys may think Iv missed?

poor car..

^1 on what Jonson suggested..

or try bypassing th IFS.. and go from there..

no spark = no combustion

I don't know if this is the right section to post in but i searched and nothing came up.

Basically after a minute or so of the car being started, the AYC light comes on and stays on. assuming there is a problem with the AYC, any idea what the problem is and how to rectify it?

All thoughts appreciated

Weird that all plugs could be fould all of a sudden right? Poor car... Ill remove plugs. Reset gap and try again

 

[Guest]

Ok I'm writing this as i go along.
Plenum removed. Is wet with petrol a bit so flooded somehow maby ?

 

[Guest]

Ok rears removed. Regapped and cleaned.
Now for fronts

 

[Guest]

Cleaned fronts and teassembled. Swing. Fired first pop. Ur a top chop Jon lol. Car died so tighten intake up etc an then should be sweet

 

[Jonson]

Cool. Easy fix. Iridiums and most other plugs foul up very quick with cars that run rich (like ours) and all your doing is moving them in and out of the shop/driveway. I try to keep the cars running for atleast 5 mins when I move them in and out.

 

[chardo]

Damn, 30 mins to replace all 6 plugs, you work fast..

 

[naughtika]

try 25mins

..but at least that's 1 stuff sorted out..

...NEXT!!!!

 

[Jonson]

Are you having a coffee with that too Christian?

 

[dwarfmarine]

try 25mins

I've got it down to about 40 mins In and out with a cool engine.

 

[naughtika]

Are you having a coffee with that too Christian?
