I put in the used ECM and that seems to have taken care of everything. It didn't look very promising. One of the connectors had part of the plastic broken off and several bent pins, but I straightened the pins enough to get the connector on. The transmission fault code must have been a glitch, it ...

I've checked everything else I can think of, so I bought a used ECM on ebay and should get it in a couple days. I'll have my fingers crossed when I put it in because I don't know what else to do if that doesn't work. Thanks for the suggestions.

Today I checked those ground busses and they both look clean and tight, wiggled the wires etc while cranking. No effect. Also, I cleaned and tightened the batt terminals as much as I can. No effect. Later, when I was hooking up a remote starter switch to test the injectors I noticed that the cooling ...

Thanks, I'll check those tomorrow.

1994 Bonneville SE. Last week while driving at highway speed the engine died. Cranks but doesn't fire. Fuel pump runs and there's pressure at the schrader valve. Spark looks good at the coil packs. When I tried to scan for codes my reader just showed "error-check connection". This is a '94, so it's ...

All joking aside, small animals find their way into the strangest of places in vehicles.


LOL. I hear that. Over the years I've had tons of mice, voles, even chipmunks in my cars. A '67 Lemans I have couldn't even run because of a mouse nest in the muffler. But in this case it's red squirrels ...

There are literally squirrel's nests clogging my squirrel cage and heater/ac blower motor. I have 2 1994 Bonnevilles. One has been parked outside, unused, most of the winter. When I started it recently the heater fan was extremely loud at first and later returned to normal. The other Bonn was parked ...

I took the Bonn to a couple GM dealerships today and neither one had an adequate handheld scanner, even though they assured me they could scan the codes after I explained about OBD 1.5. They wanted to charge quite a bit for a full diagnostic, with no guarantee that it would pinpoint the problem, so ...

Do you have a laptop/notebook?

I do have a laptop if there's some easy way to get the codes with it. You're right about the paper clip not working, this has the OBD 2 connector. Thanks for the replies.

About a week ago the "Service Engine Soon" light came on in my '94 SSE. I haven't driven it much since then, but it has stalled a few times and the torque converter doesn't lock up anymore. I haven't been able to find anyplace that can scan the OBD 1.5 codes. Does anyone know which scanners are ...
