If the 12 Volts are being supplied to the fuel pump, you have now 100% verified that the fuel pump is fried and needs to be replaced.Д¬ASE 2: If the fuel pressure gauge registered 35 PSI.

What you'll have to do to accomplish this is to attach a multimeter in Volts DC mode to the wire that supplies this voltage to the fuel pump and while a helper cranks the engine, verify that the fuel pump is getting this power. This is just to make sure that the fuel pump relay and fuse are OK and doing their job. Now, I'm going to make one more recommendation to you: Before you condemn the fuel pump as bad, check that the fuel pump is getting 12 Volts as the engine is cranking. This confirms that the cause of your 3.8L equipped GM car or mini-van is caused by a lack of fuel. Your fuel pressure gauge will register one of the two following results:ДЎ.) The fuel pressure gauge will register 35 PSI, orДў.) The fuel pressure gauge will register 0 PSI.Д¬ASE 1: If the fuel pressure gauge registered 0 PSI.

Your local parts house will have a fuel pressure gauge set to sell you, although you'll pay more for it and it won't be a professional grade tool (if that's what you're looking for). Whichever one you buy, it's an investment that will pay for itself many times over. The price difference depends on whether you're buying a non-professional technician grade tool or a professional technician grade tool. In all of the GM 3.8L V6 equipped vehicles, GM was kind enough to put a Schrader valve on the fuel injector rail where you can tap into the fuel system and check its performance with a fuel pressure test gauge.ДЄ fuel pressure gauge can cost you as little as $40 (US) or as much as $200 (US). All vehicles now use an electrical fuel pump to deliver fuel (under high pressure) to the fuel injectors and the best way to diagnose this fuel pump is with a fuel pressure gauge. Owning a fuel pressure gauge is now becoming a must. Which And Where To Buy A Fuel Pressure Gauge

You've sprayed starting fluid (or carburetor spray) into the throttle body and your car (or mini-van) started, even if only momentarily.ДЄlthough the above list is a not a very complete list of symptoms, the theme that runs thru' them, and any other related symptom, is that the engine will crank and crank, but not start.

You've done a fuel injector Noid Light test and all of the fuel injectors you tested are getting their activation signal.

So you know that the ignition system is not at fault.

All of the coil packs, sitting on top of the ignition control module (ICM), are creating and delivering spark to the spark plugs.

Well, there are a few other specific symptoms you'll see. I mentioned at the beginning of this tutorial that a bad fuel pump will cause your 3.8L equipped car or mini-van to вЂcrank but not startвЂ™. You'll be able to accomplish both tests, indicated in this article, without any unhappy consequences, if you're careful and use common sense. Take all necessary safety precautions and stay alert.

IMPORTANT: Gasoline and starting fluid are extremely flammable! Be very careful. You can find this tutorial in Spanish here: CГіmo Probar La Bomba de Combustible (GM 3.8L) (at: ).
