help needed about a Cadillac seville 1977
I'm a brand new user of your forum and hope you'll be abble to help me
i own a 1977 Cadillac Seville oldsmobil engine 5.7 350 ci first injection
While driving I've set it on cruise control then the engine stopped
I've alredy checked a few things :
the gazoline in coming to the engine
spark at the spark plug
I've changed the gazoline filter and put a new battery
I've noticed that there is no electricity at the fuel injector
It's been a while I'm mashing up my brain and fingernails !!
Any clue guys ??
Check for a blown injection fuse, it will be marked INJ, you could have 2. if those check good then check if you get an injector pulse signal from the ECM, if you don't then the next step is to have the system checked and these old Caddies had their own way of accessing the system. Here is a page you can look at but it usually sends you to using the old Cadillac analyzer:http://www.cadillacseville.org/technical.html
