1984 Buick Riviera T-Type (one of 1153) $3000 116k miles. Sand gray firemist with gray leather interior, brown dash. 3.8L SFI turbo 4speed auto. Obtained from original owner with good documentation, extra parts, manuals, and “window sticker”. Only a very little rust, solid. I have/it came with...

I know another one of these but I have not found any previous situations like this. I replaced my cam sensor cap with the Caspers one with the light according to the instructions. I actually got some life out of the engine (first time this season). It barely idled for about 10s. Other starting...

Have been trying to get this 84 to run. What is the good values for the "B5" reference signal from ignition module to ECM look like using a volt meter? I know it is to vary but what range? Low to high? I have a constant 4.6V when turning the engine by hand. Crank sensor is good, cam sensor is...

What are the better/easier locations to tap for oil pressure and coolant temp. Photos please. What fittings are needed?

Checked for crank reference signal at PCM (A/B connector, socket B-5). When cranking there was a constant 11.4v not the expected 1-7v varying signal. What are the failure modes for this sensor? When I get a chance I was going to check the 3-way connector next.

Change to original PCM, sputtered for about 20-30 sec. then the same no start. Will hit a cylinder once in a while. Check eng light on (computer responding) Fuses ok, added another gallon of fresh fuel. Could not easily get to the injection 3way connector so just used a "Noid" light, never...

I have read that it is difficult to get a good replacement MAF for these cars. Has any one found a decent one?

Well actually had it running good, corrected many issues. Still have intermittent C14 (maybe PCM?) Shut it down, went on 2 week business trip. Went to start and drive it but batt was low (cranked slow). Charged the batt but now it is hard to start and won't idle and stay running. Lost learned...

Recently got this, had a bunch of maintenance done. Timing cover gaskets, coolant, hoses, oil/filter, trans fluid, valve cover gaskets, coolant temp sensor, some vac leaks fixed, intake tube crack patched. Just trying to get it to run right before anything else. Same engine as the Regal, just...
