How are the Quad injectors set up on a car?
On your car the ECM is set up with two quad injector firing sequence. All even numbers and all odd numbers. It is rare that both would go out at the same time. The ECM grounds the injectors, so I would check for power going to the injectors first. This could be a fuse or a bad wire. One wire feeds power to the injectors until it reaches the engine.
Where do the injectors get their pulses from?
I borrowed a set of Noid lights at Autozone. They proved that there is no pulse going to any of the injectors. The injectors, or pulses to them, are definitely the problem. Do the injectors get their pulses from the module inside the distributor, or the ECM, or both?
Is there a fuse for all 4 injectors?
The schematic shows each set of 4 injectors has its own fuse as a power source with the key in the RUN position so I would verify that voltage is present at the injector plugs. The odds of both fuses being blown may be slim but it should not be ruled out.
Can a bad fuel injector cause a check engine light to come on?
A bad fuel injector can cause your 3.8L Buick (or Chevrolet, or Pontiac, or Oldsmobile) to idle rough, miss, and make the check engine light come on (if the vehicle is ODB II equipped, you could see misfire codes: P0300, P0301, P0302, P303, P0304, P0305, P0306). The good news is that testing for a bad fuel injector is super easy on the 3.8L GM V6.
How to test for bad fuel injectors on GM 3.8L?
The good news is that testing for a bad fuel injector is super easy on the 3.8L GM V6. There are many ways to test for a bad fuel injector and in this article I’ll present to you one of the simplest of all: verifying the resistance of the fuel injector with a multimeter.
Can a bad fuel injector cause an Oldsmobile to idle rough?
A bad fuel injector can cause your 3.8L Buick (or Chevrolet, or Pontiac, or Oldsmobile) to idle rough, miss, and make the check engine light come on (if the vehicle is ODB II equipped, you could see misfire codes: P0300, P0301, P0302, P303, P0304, P0305, P0306).
How do you test the resistance of a fuel injector?
Probe the male spade terminals of the fuel injector with the multimeter test leads to get an Ohms measurement. It doesn’t matter what color test lead you use to test either of the two fuel injector male spade terminals, the polarity of the leads is not important when testing the resistance (Ohms) of the fuel injectors.
