Reason For Bad Start Rb20det

[aussy-boyz]

Fount 2 wires cut behind intake manifold. pretty sure they are for temp sender, a green and a blue/black wire. looks like there have been cut off a plug, trying to find were they go not having much luck, can some one have a look or tell me were the hook up 2?? might need to pull main loom apart looks like its been taped up may have cut wires in there.

cheers

only wires I can think of which are behind the intake manifold is the plug for the IACV valve (Idle air control valve). Might explain bad start as mentioned in your title?

Take note of the brown plug to the right of the photo. Do you have those wiring? (disregard the red circles)

[aussy-boyz]

yea iv got the same wires. the wires cut use to have a connection on it which goes to another connection going to the heater hoses on the fire wall at around the same hight as the wires. mine have been unplugged for years.

hmm so that may not Be the reason for Bad start.

what is it doing to not start properly?

[StealthX]

Done a compression test lately? I.e. Is the motor healthy?

Do you have an aftermarket engine management??

[Rekin]

The other end goes to a hose on the firewall. No idea what it is though...

and the pics

Those pictures doesnt work,why?

[aussy-boyz]

comp is good, starts straight up with a bit of carby clean in intake, or else it like starts to fire but wont keep going like its not getting enough fuel. it misses at the start until its warm then its all good,

[aussy-boyz]

alright im off the idea off that plug still think something to do with temp sensor heres a vid of wot it does, seams like its not getting enough fuel for start up
