First off sorry about the drawing..lol. I will check my manifolds very carefully again, i block the egr off..i will check my pcv plugs..and any nuts and bolts. I was planning on connecting the pcv vent with a T adaptor and connect to the brake booster and the tube on the back of the intake.. As for my icav i don't have the brown n silver dot connected is was cut. things i'm not sure of are: how to check my MAF voltage..check or adjust tps and the timing as to how much.. i'm will report my finding as soon as i get some more courage....i'm just still hating it... Thanks..

q-tip, I have not attemp anything yet, will keep post soon.

i'm so desperate for any help i did PM Icehouse and Creepycrusier, but i know they are very busy and probably tire of some of our KA nitemares...lol. i need to get this 510 back on the road. The 510 is just teasing me now..it starts but can't run right...Banzai...Thanks.

Q-tip, i have been busy and have not attend to the 510, but i will report ASAP. Just been doing more researching instead of diving into it. Do you think it could be any of my iacv or tps? i'm thinking about routing my pcv to the intake and see if it helps. Right now i just have the pcv vent to atmosphere.

Got it...thanks for the tip.... i guess i'll have to get some quick pixs...let me konw of other general rules as well.....sorry

hello to all ratsun members, I didn't know where to start so i'll just post my intro here. I'd like to say this form is the most complete information of help for all datsuns. i love all the great post, help, and people from just reading old and new post. Thanks, BluDimer.

Yes, running it the way you're telling me to do so is running through the rpm. It's just not idling to well. I have not done anything yet. How long should i let the engine run until the computer recongnize the change and if i have to reset how do i do so safely?

The ECU is has not been reset and is the same. The only differences is that the ECU is not mount it's just sitting on the floor pan. I'll try to do what you suggest when i get home or a chance to. i'll update asap as i do want to get this car back on the road asap. Thanks ...

It works better with the vavle cover vent disconnected from the intake and with just having the iacv connected to the intake. Just like Indy510 if i disconnect the MAF is running all day but not good, because not a right air fuel mixture. I've even spray starting fluid around the intake side and didn't notice any changes. my knock sensor, maf, O2, igniton coil is all connected.

Darn another KA issue. I feel your pain, this is what happens to us newbie try to clean up our engine bay. I know you've already checked, but it really sounds like a loose ground wire possibility. See if you could start the car at the starter by bypassing the ignition.

It's the same everything, if i keep on reving the engine it will stay running. I have not tried unpluging MAF or spray any starter fluid yet. On the starter fluid what i'm i looking for or suppose to see or hear> Indy510, sorry to pull you into this, but i'm starting to hate this. All i want is to drive this thing around. but yeah i should of left everything alone..lol. Q-tip, i will try that when i get home. I've search here over and over hoping i'll find a fix, but yet nothing. i really want to understand this whole KA error. I'm in central, CA and is ready for a local expert to come and lend a helping hand over some beers.... :thumbup:

The only change is it PVC filter and removal from bottom of top intake. Thank you.

I have a 510, but totally agree on what your doing. Although i should of left my wiring alone..lol.

Hello ratsun, I've already post in the engine section, but not sure this could be a electrical wiring issue as well. If not please let me know and i can delete or moderate can do as well. I have a (91-94) KA24DE in a datsun510. Everthing works great until I attemp to do some wiring and hose clean up. What i have done: remove and plug PCV with thread bolts under the intake. Insert and filter into the PCV outlet. Cut and clean up heater hose and non-use vacuum connection under bottom intake. Ran heater hoses direct to heater core. Check as carefully as possible and cut, shorten, and solder all connections. Relocated stock fuse box inside the cabin. Now the with key on I can hear fuel pump on as it is priming gas. Then it stops I then start the engine and it fire right up with no problem. Idles for a bit then slowly blogs then dies. What I have checked and replaced: Fuel filter Mass air flow meter Fuel pressure regulator read 14-16 psi of vacuum. Check wiring again as what I know. My IACV AAC does not have the EGR sensor wired. My IACV AAC does not have the EGR two wires wired. My IACV AAC does not have the brwn and sliver dot connected before or after the issue. I’m stumped here and really need some professional help. I want to get this car running again. Thanks, BluDimer

Below is the wires i have cut and will depin. The XXX's are questionable and my KA is auto not manual. Is there more that i can do? because my wiring loom top and bottom is stick very thick and not slim as i would like or seen on some of you senior members. Any help is well appreciated and thanks ahead.
