fiddled around with the dist some more, got it to idle, still a good amount of smoke, but less then yesterday. gas gauge at E and im not gettting a reading on the pressure guage so ill have to get a can of gas tomarrow lol, that might explain why it wants to stall when revved!

update!

got a 5 gal can of gas... now im actually getting a reading on the FP guage....

start the car... got it to run awesome! then the carb floods and car stalls. i lowered the regulator down to 3psi, as low as possible, and the same thing accurs....

i went back to all the paper work that came with the regulator and noticed it says the return line should be equal size or larger the then input line (from tank to regulator)... well the stock return line is one size SMALLER then the input line and it appears that the fuel is just backing up and pouring into the line to the carb.

if i pinch the line running to the carb and release as fuel is needed it will run perfect, but if i leave it alone again it floods and stalls...

i didnt read about this problem anywhere from the tpi to carb swap sites.... maybe since my car was originally TBI it had a smaller return line then TPI cars???

if thats the case only thing i can think of would be to pop in a TBI pump since they only run at 15ish psi IIRC as opposed to the 50ish psi for the TPI pump, thus allowing the regulator to not get backed up with the smaller return line..... if that makes annnyyyy sense lol

Fuel Injection for the win. The most reliable fuel system <3

why can't you put in a larger return line and be done with it?

thanks for the help........ if u read the begining ud see i wanted to learn sumthin new, i did TBI and TPI on this car already....


all the way back to the tank? i think itd be easier to pop a new lower pressure pump in, and prob cheaper

easier, probably. cheaper, depends on your resources. if you think it will work and not give you problems down the road, by all means do it! i'd hate to see you backtracking and throwing money out for nothing. post up how it goes.

so i was told to check on the floats in the carb... losened up the top piece and played with them, appeared fine, bolted it back down, problem still there....

removed the entire top of the carb.... only to find one float FULLLL of gas and one of the seams opened up, that would explain it not floating up and shutting down the fuel delivery and causing it to flood... right?

i found new floats on summit for like 14 bucks, guess ill be ordering them

How old is the carb? Does it have metal floats or plastic?

brass, no idea on age altho its extremely clean and all the gaskets look new

ok new floats in, runs awesome! i actually drove it around the block :)

but now of course new problems arise! alternator not charging! checked the volts everywhere, all equal at 11.70 and all droping at the same rate while the car was running, guage in the red... time for a new alt!
oil leak like a mofo i think coming from the oil filter, needs an oil change anyway!
cooling fan not coming on/HVAC blower motor not working.... i looove wiring!

I'll have to look at the wiring for the alt. and post it up but make sure you didnt cut any wires that go to the connector on the alt and make sure the power output from the alt is going directly back to the battery or to the little terminal (stud) mounted on the battery tray on the side of the battery.
The problem you are having is going to be chasing down all these wiring nighmares becasue of trying to reuse the factory harness. Your best bet would have been to completely rip out the harness cut out all the fuel injection parts and pretty much rewired it from scratch. Alot of the things your trying to reuse were controlled by the ecu. Such as the cooling fans.

QFT I bet that alt is working fine but not wired right.

You dont want to buy a new alt and give them a perfectly good working alt core, I know I did that traded my 100 amp alt in for a smaller one because I need it to work to get back and forth to work. Turned out it was the battery and the alt wiring!!

i didnt hack up the herness at all, i cut out 4 injector wires, the air pump wires and one other thing, the rest is all there still, with the ecu plugged in...

Thats OK that you didn't hack anything up but even if you still have the ecu hooked up its still not going to control anything because its no longer getting a signal from the module that was in the distributor to say if the car is running. So as far as its concerned the car is not even on. You can pretty much just disconnect it.

does the alt even have anything to do with the ECU, i plugged in teh scanner and the ECU is showing 11.9 volts and it still has a coolant temp reading... all the alt wires look good too

cut the red wire on the 2 plug connector and run it to a keyed power source. problem solved

but im already gettin power on the wire....

which wire? the 2 prong or the single wire that bolts to the back?

on the weather pack connector do you have 3 or 2 wires? If its 2 wire then pin F is a brown wire and is from the fuse block with a 20 amp fuse, on my chart its the same fuse as the fan fuse. Pin S is a red wire that has a fusible link that goes to the starter. The ecu is not connected to the alt.

Hold on. What harness is in the car now?

This is the alt & starter WD from the autozone site for 88 Camaro body harness, I added color. Chk that fuse, chk those links.

bingo! lol so the alternator not charging has nothing to do with the ECU!

lol bonzo its now got a 90 tbi harness... gets hard to keep track of!

LOL, I can't keep up. But what I posted is 88 body harness, not sure if you swapped that. I'll check the other too.

Edit: 90 body harness shows the same ALT circuit I posted above.

IIRC, if that brown wire is not energized the alt will not 'turn on'. I could be wrong. For the link you need to check for continuity from end to end.

yeap. brown wire has no power.... i traced it back as far the the rear ps valve cover, and checked the fuse... is there a ground somewhere? my fans not turning on either...

Yeah that brown wire is power for the fans and the alt. It gets power from the fuse box. Did you accidently cut it and use it to power your dist or electric choke?

haaa it turned out to be wat i suspected!.... the 90 harness is different from my 88 fire wall connector. the brown wire went to nothing! i tapped the brown wire to an emmisions wire im not using and the alternator was charging...

now, can i move that wire to a diff spot on the firewall connector, maybe group it with the fan wire, since thats where its moved to in the earlier cars, orrr try and find an 88 camaro tbi harnes?
