Too Late! Read the email too late to consider Howell EFI. I've already ordered from Ecklers. Anyway, Howell didn't have anything listed for an 84. Only 87 and up. Ecklers ECM should be here tomorrow. That's one of the reasons I ordered from the. I believe I must have had the ingition on when...

Fuses are OK Went throught the injector diagnostics step by step and every symptom leads to ECM problems. Checked all the fuses, all working. It's not a big deal to replace the ECM is it? Ken

Crap ECM is toast. Followed the diagnostics in the service manual. Test light stayed on during cranking. Shorting PINs A & B on the ALDL did nothing. No check engine light. Fuses were all ok. Resistance between terminals was greater than 1.4 Ohms. All points to faulty ECM. I guess I'll...

Error Codes..... I hooked up my scanner last night, and when I tried to scan for codes, the scanner said the computer wasn't responding. I looked at the ALCL connector, and it looks like the previous owner might have done a hack job on it too. Ken

sumtin fishy I'll check for ingition pulses this evening and also check for fuses. I hope that is all it is. After thinking about the sequence of events last night, I can't say for certain that the ingition wasn't on. I'm pretty sure it wasn't though. What would that do if it was on? Blow a...

Key was off when the battery was pulled. No fuel coming out of the injectors. Ken

84 CF won't start????? Vigman, Remember this subject in the first thread? After disconnecting the battery, the injectors aren't pumping gas anymore. All I did was disconnect the battery for one minute to allow the ecm to unlearn. When I reconnected it, the motor turns over but no fuel is...

Thermostat housing Thanks, it's been a real pain trying to track down all the parts. The housing points up at an angle (30-45deg)and towards the valve covers. Standard for Chevy 350 Ken

different than the '87 I imagine so. Try putting this intake together from scratch. There use to be a Holley and Edlebrock intake on this engine. Talk about a learning experience. Ken

84 intake picture I hope this is large enough to see the detail. Excuse the mess, this is a work in progress. Ken

TBs balanced Vigman, Front TB was drawing to much VAC as you suscpected. Checked it with my vac gauge. The rear barely moved the needle, and the front registered over 10 ". Adjusted the front TB until it read the same as the rear on the VAC gauge, then attached the mannometer and adjusted...

All unused vacuume Ports Plugged I'm thinking now that I screwed up the throttle linkage adjustment. I've got to reread the instructions again. If I'm correct, the throttle linkage should be completely out of the picture when the TBs are adjusted. I'm not sure now that this was the case...

Mannometer tests Yes, the picture you included is essentially the same as what I have. Mine is mounted on wood. As per the instructions, I started on the rear (drivers side) TB. It measured 2" of water. Adjusted it to 6" as per the instructios. Did the same tests with the front (passenger...

Mannometer Problems Yes, used the center port on both throttle bodies. As I said, the rear showed 2" when I hooked it up and was able to adjust it to 6" without issue. The front was done the same way, but it sucked the water right out of the tube. Should the screw be backed out on the front...

Problem Balancing TBs Seated the IACs Hooked up home made Mannometer to rear TB and it was measuring 2". Adjusted to 6" and it significantly improved performance and picked up the rpm. Heres the problem. Hooked up the mannometer to the front TB, and it sucked all the water out. What's...

ALDL?? I feel stupid for asking, but what is it and where is it? Ready to balance my TBs and need this info. Couldn't find any reference to this in my Service manual. Ken

I just bought a new roof panel from Generation Ropof Panels, and here is what the guy said about mounting a new panel. (said if you don't do it this way, it will rattle) Make sure front locator pins are not tight. (The front bolt holes move until the locator pin is tightened) Mount the top and...

Good News Replaced CTS & found the shorting wire. Results: Car starts without touching the throttle & idles on it's own. IACs are now seated and working. Runs pretty smooth, but still a little sluggish when you tap the throttle. Balancing the TBs and rechecking the timing should finish the...

I feel your pain Hey, that guy got to my 84 vette as well. 1. replaced the CF Intake with a caburator and Edlebrock intake. (destroyed a holley when he forgot that the holley wouldn't handle the pressure from the fuel pump) 2. Disconnected or cut most of the engine compartment wiring harness...

AOL Vigman, I don't use AOL or instant messaging. Never tried it. Do you have to be a member of AOL? Ken
