I am done sick of my computer system/ money pit.

I am about ready to swap to reular HEI and carb.

Unless anyone can offer solid proof on what parts to change and will back that up with money out of your pocket if your wrong.

As of now, there is no proof that several hundred dollars in parts will fix anything.

Where going to a regular dizzy and carb will.

You can tell Im sort of fed up and need help in one direction or the other.

See post if you wish

Well first off, please tell us exactly what it is doing then list all the parts in order that you have replaced. State whether they are NEW replacements, what brand, Used?, How old they are. Then list any testing you may have done.

I don't know what kinda problems you have, but I can tell you what will work cause i've done it and my 1983 2.8l camaro ran fine untill I pulled the motor out to freshen it up(started to smoke, sat for a long time).
One buy the edelbrock intake manifold for a 4bbl, then buy a holley 390cfm 4bbl. That will eliminate the computer controlled carb. Second go to Auto Zone buy a dist. for a CANADAIN made 2.8l that dist. has vacuum advance on it then buy a universal ignition coil and hook everything up and your computer can be disconnected alltogether. Any carb from the 80's that were computer controlled always had problems. I had an 1987 Dodge Charger 2.2l I-4 with the same set up, I swapped that carb out as well for a regular Holley 2bbl.
This is probly not what you want to do but it the only I can tell you for now.

Thanks allot there, besides maybe less mileage did it perform the same over all???

As is its super annoying as replacing computer parts are no guarantee to fix anything. Gonna cost about $200 for ECM, prom, MAF, AIT and it could still run like crap. Where it ran great for 7-8+ years.

No need to retype everytihng if you follow the links posted above it tells what all my problems are.

Not to sound like a male reproductive organ, I am not going to sift through the words finding out what you tried/tested etc.
You want help, please help us so we can possibly help you.

well i have had the same problem with 2 different cars with efi b4.and after changing a sh@t load of things i found that puting a 4bbl and geting rid of the electronics is the best way. and i found some power going from tbi to 4bbl if yours is tbi you should feel the same but if it's mpfi you may not get any more or even lose some.but at least it will work good

[no_doz]

fuck it-megasquirt and turbo the piss outta it

What kind of cost was that, new or used parts.

Think I might have better luck finding a canda site since they did the regular HEI n carb more thne the US???

Id perfer to go used on parts. doesn't have to be a 4bb either, id take 2bb stuff if it was cheap.

[montess408]

i did new for one and used for the other. it should not be hard to find old s-10 parts in a J/Y early 80's s-10 had 2bbl carbs

If anyone can offer any more tips or possiable leads on parts let me know.

[gsEnterpries]

i would look on car-parts.com for the intake carb and distributor it's your best bet.
i remember when it happened to my 3.1 i replaced the fuel pump,fuel filter,ignition module and coils,plugs,wires various sensors and checked and rechecked the harness as well i got used injectors and ecu. i spent around 500$$ and i never found out what was wrong.

It’s Alive!!!!!!

Thank the lord.

The ECM replacement was a total shot in the dark.
Did have a few hiccups at first.
Had to wire my fuel pump back up as it was on a switch.
[Computer turning it on should of been a clue]

I was then able to get the 2nd ALDL cable I built working and was able to do some data logging.
