View Full Version : How do you pull codes from a 1994 ecu?
This is on a 350 tbi indmar/mastercraft. It has been my experience that this can usually be done with a jumper and a lightbulb or vom, but the Clymer manual I bought doesn't give this information. Can anyone help?
Thanks in advance...
Do search here- it has been posted many times. Why do you think you need to find them?

Where do you live? Take it in to your local dealer and they can probably pull them for you.
Thanks Jim. Found it. If you get a chance maybe you could take a look at my post "Looses rpm after several minutes of running" (at wot). It's on page 2 now. TIA
Start by checking the fuel pressure while you're out. If it starts to drop, it's probably a bad pump. if it doesn't drop, it could be a clogged vent line. A leaky fuel pressure regulator hose or vacuum leak could cause problems, too. I made an adaptor for measuring pressure on non-Shrader fuel lines myself, from parts I bought at NAPA. You could also look for a shop that makes up fuel lines, with the crimped on fittings. Don't cheese on this- if a rubber hose and clamps are used, it's not going to last long. Once that's done, you can attach a gauge to the fitting and read your pressure.
I haven't heard of injectors that became slow to react over time. A dirty ground on the block could cause problems but until it's tested, it would be hard to say exactly what the symptoms would be.
Thanks for the help, Jim. and everyone else, too. With fall comming up and forced ot at work, it may be a while before I get to try anything, but at least now I have some information to work with.
