Seriously?

 

No.....

 

Yeah, It looks like it would work.

 

Im starting to associate your name with............:laugh:

 

Well, the steering column is from GM..

I know HO engine wiring harness can be modified to carry the signals for a 350 SBC swap using GM computer, and IIRC it requires the use of the stock ECM unit in parallel for some of the stuff if you want the stock gauge cluster to work. But it certainly isn't a swap-some-stuff-around thing to do. As for directly swapping in an S10 computer to replace the renix computer.. no. What the heck makes you think the engine management and programming of the ECMs would be similar on an inline-6 AMC engine and a V6 or V8 GM engine even if the ECM units and their connections would be the same?


What is the problem with your renix computer? I actually highly doubt the main problem is the computer - most likely it's the wiring harness and all the connections. If they get corroded, you will end up with serious malfunctions. Grounds also need to be clear of corrosion to ensure proper functioning of the engine management and all other electrical circuits.

 

The problem is you can be driving, and it will randomly lose power and start missing and sputtering like its out of gas. I have replaced ever sensor in it that is associated with this problem, and the computer is a Re-manufactured unit, the original shorted out. Should I try a junkyard computer or put a totally different motor and wiring harness in it? By the way, the grounds are clean.

Page 3 has the fix

 

Have you checked fuel tank (fuel intake tube), fuel pump, fuel filter and fuel pressure? I had similar issues on my XJ a couple years ago, problem was the pickup-tube/ fuel pump assembly had worked loose and it sucked in air occasionally.

Replacing sensors randomly won't help a thing, you gotta properly search for the problem (multimeter and a renix service manual is your friend). Also check all the connectors for corrosion, it's certainly not uncommon to have corroded connections on a vehicle of that age..

 

The fuel pressure is fine, but I had it on a computer to day and the fuel trims didn't line up with the factory specs. The short term fuel trim, would start at 120 and work its way down to 0 and start missing and sputtering.

 

Ever do a sensor ground test? Takes less than 5 minutes. I'm betting this is wiring related. Also it's an 87. Ever cleaned out the c101 connector or bypassed it with your CPS wirs?

 

would you mind posting the test? i would like to just check mine, for the hell of it.

 

The column is GM, most of the sensors are GM.

The dizzy is Ford, the control setup is Bendix.

The plug isn't even the same sort, much less pin-compatible. No, that's not going to happen. I wouldn't even try to adapt it, and I've made some awfully bizarre stuff work (I don't think that GM had an electronically-controlled pre-OBD inline six, just V6 engines. The electronic controls are OBD-II, for the reissue of the I6 in VORTEC trim.)

 

Re-read post #9 and please answer the questions there. The C101 connector carries all sorts of critical info between the ECU and sensors.

 

I already cleaned the C101 connector and the grounds, still no change

 

did you even read the thread i posted? I had nearly the same issues, replaced ~1k$ in parts...found out it was one bad wire in the loom. You need to start unplugging connectors and start testing resistance and continuity.

 

Yeah I did, everything checked out fine, I still say my computer is messed up

 

What was your average resistance? High? Low? Did you test the pins on the computer that lead to ground on the firewall? With a helper the process takes a few hours minimum.

 

My jeep died on me awhile back ago, would just sit there and crank. checked the wire's replaced $400 in parts and still nothing, it end up being a bad ground wire that looked fine on the outside.
