View Full Version : 99 Deville Northstar-New fuel pump, but wont start

Fuel pump was going out and then eventually died. I replaced the fuel pump, but car wont start. The fuel pressure is good, injectors are good, spark is good. Any ideas?

Just did this job over the weekend. Not to be a smart arse but one of those things you listed as good, are not! How do you know your fuel pressure's good, checked it with a fuel pressure gauge. Can you hear the pump run. How do you know the sparks good? You Air Fuel and Spark thats it. Any codes?
