I havent been able to get my 86 na started for a week now i let it dry out last few days and put a battery charger on and it still wouldnt started, i ended up pulling on the manifold from the passengers side to get it to start...it started and every time i let the manifold go back that slight bit and wouldnt start, I noticed one of the harness nuts wasnt on tight so i pulled and tightened it up. The car ran it idled no problem a lil sputter so i played with the tps and CAS, still ran, i then procedded to make sure there was no air in my coolant lines so i undid the rad cap and the bleeder screen i was able to get them closed back up not much to get air out, so i went to start my car again and no go. not even close to starting? oil smells like gas hmmm im lost why would it start when i pulling on the UIM towards the passengers side? Any help would be appreciated!!!!

Went back tonight got no spaark now any ideas?

tew

It sounds like you have a bad conection, someweher in that wire harness. You'll have to go in there and investegate a little more. A good test light should be a help with this. Check your ground+ main connectors and other obvious, but often overlooked stuff first. Let us know after that.

PK797

there is a ground bolted on or by the egr valve im pretty sure its your problem.check it and get back with us



David

how do you suggest i fix it ?

well find it (remove uim and look for a wire going from your harness to the egr) ,check to see if its broken any where or has come loose. Then bolt it back down or replace the wire. You have two grounds one coming from your harness to the egr bolt and one from the bell housing to the firewall the one im talking about is the one to the egr but i would check both just in case



David

I replaced the one from thebell housing but the bolt fell down and didnt drop out the bottom of the motor so i ground it to the intake manifold, also there was a wire with some kind of black resistor by the oil filter that i cut the onds off of and twisted the wires together, is there another wire under the intake manifold i should be looking for? Also i get 7 volts the first front iginitor and zero at the back? Bad ground?





Help me please....

ok went and took the uim off and tightened the ground it was loose still no start a lil spark from the fron plugs didnt check the voltage of my coils again i didnt have time........could something have gotten wett by the air box when i bled the rad, would that make it not have juice in one coil and have juice in the other? 7 volts in the front one and nothing in the back one?

You might have blown your engine fuse. Is your fuel pump coming on for a few seconds when you switch on the ignition? If not then there is a 15 amp fuse on your kickpanel fuse block that might be blown.



This is only 1/2 of your problem though. Now you will have to figure out what is tripping the fuse.



Do you have a custom intake on your car? Make sure it is not rubbing the fuel pump relay wires.



Good Luck.

if the afm connections are bad it wont run either

can i cut the connections and run them straight through?

also i belive they got wet when bleeding the rad so if i dry them with a hair dryer hopefully this should work?

AFM do you mean the ones attached to the air box?

yes

Thanks im pretty sure its ethier them or the silinoids down under the air box being wet b/c of the weird voltage at my coils i took the connects off and measured the voltages across them and the front has 7 volts and the back has 0. so i figure they might be wet.....watcha think?

Well i thought id be different and tell you all how i fixed my problem i used a hair dryer...Pulled out the airbox and blew dry everything under there....left the hair dryer going for probably 5-6 hours today and it started on the first try.......so for those of you out there with no spark or a little spark make sure the area under your airbox is dry.....very dry......mine fires up no problem.......also it didnt look very wet but it is hard to tell with silver coloured "colored" connectors. I drove it home tonight and seems good so far a little sputtering but i read sumwhere on here a post about my ecu causing that and to solder the wire or something.

That is only a temporary fix. You have something shorting out. Make sure all your connections are clean and no wires are frayed.



BTW - Congrats on getting her running.

Sh1t dont tell me that :( Will i have to trace the problem further replace some of the electronics up front and if i do that can i replace them with better ones? I have an 86na ...thanks
