Yay! An awesome update, glad to hear it's running again!

UPDATE:

She's running, and better than ever.

I go to check my fuel today..

I have fuel pump going, injector are getting pulsing.. so i pull a fuel line and to my suprise there is no fuel pressure in the line..

i jump the FP relay terminals and I test the pressure and flow.. it has flow but very low pressure.. and after i turn it off it doesnt even hold pressure, within a couple seconds its zero pressure...

So i get into the fuel tank and while running the pump look inside through the level sender hole.. and there is a lot of fuel moving around in there.. so I remove the whole fuel unit and...


what do you know, I guess the hose i used could not handle being in the fuel.. replaced it with one that is specifically for fuel only.. and put it back in the tank.. a couple cranks and she fires up running smoothly.. let it warm up and go take it for a spin, and it has more power and throttle response than before.. i was getting sideways in 2nd gear! (prob because I cleaned the AFM and adjusted the TPS and cleaned out the throttle body..lol)

So now look forward to more Race Car updates!

Dope thread! How did you go off on turn 9 at Laguna?

tried taking the corner a little bit faster, BFG Rivals broke loose, and i over corrected, because i didnt want to go into the wall. lol

update.

now have spark, but its still not running, the injectors are not firing..

checked reference and speed sensors in the trans bellhousing and both are producing signal wave all the way to the DME.
also cps sensor is working because i am getting spark.

spark issue fixed:
in the C101 connector, apparently there was a burnt wire and the GRN wire was completely destroyed. PO replaced the wire with a yellow one and switched the wire locations in the C101. The pins male and female in the connector, one was being pushed up into the rubber cover when connected, but when disconnected appeared to be fine.

well idk whats going on with my car.. now its not getting injectors or spark.. maybe a bad ecu?

[ncrmtrsprtsE30]

I think I may have found my problem...



I went through the ECU pinout for the ETA connector testing the harness.

every single pinout was good, except for the TPS (throttle position switches)

Pin 2 (closed throttle) - has NO continuity
Partial open throttle - NO continuity
Pin 3 (WOT) - has NO continuity

pretty much no matter what position the throttle was in, it had no continuity..

checked the TPS and its soaked in oil, disconnected the connector and its dripping oil. I havent removed the tps from the throttle body yet.. but im guessing its messed up from the amount of oil I see..

will have an update on sunday.

Debating a 2.7i conversion. swap the head and electronics over to 1.3 motronic any suggestions?

do it

Did a little work on the demon tonight and this is what I came up with...

What I started with = NO SPARK, YES FUEL.

COIL primary resistance is ZERO ohms.. (should be .5 ohms)(poss shorted primary coil, POSS DAMAGING ECU)
COIL secondary is 5,750 ohms (5k-6k is spec = OK)
COIL POSITIVE POST has ZERO voltage with KOEO (key on, engine off) (SHOULD have +12V)(possible broken wire between IGN switch and COIL POS+ wire)

I hooked up a IGN switched 12v source to the COIL POS+ POST and now I have spark!

Engine should fire - nope - still no start - possible fuel problem now, since i know i have spark and compression - only thing missing is fuel - could possibly be damaged ECU.

thanks. now fix the car and get back on the track!!

Next thing I am going to try is the CPS sensor, going to replace that.. and if that doesnt work then im done with this motor.. lol

thanks. now fix the car and get back on the track!!

What was the problem with the bassett wheels?
I noted them a while back as a potential option for track/autox wheels. Seeing your comment makes me wonder if there is a reason I should take them off the list.

for one they are lug centric ONLY wheels.. so all the strain goes on the lug studs/bolts.. they actually ending up damaging my studs on the front..
also finding a shop to balance them is a pain..
they are fucking heavy, the wheel alone weighs more than my wheel/tire setup now..
but they are cheap..
BUT you can also find cheap wheel knock-offs that dont weigh a ton and are decent.. I got my Miro wheels for $260 for all 4, in a 15x8 that only weigh 13lbs each.. compared to the bassett 15x7 weighing in at whopping ~25lbs

Can you post links to the spoiler and VGs?

I hope to see this thing one day in person.

The ducktail spoiler is actually for a S13 240sx coupe from fleebay, I wasnt sure it was going to fit the trunk so i got the cheapest one i could find.. and it ended up fitting the e30 trunk line perfectly with a small amount of filing and trimming the extra piece in the back.. :up: LINK TO SPOILER

VGs are also from fleebay.. but the delta wing shaped VGs are better than bump shaped.. LINK TO VG
