How to do a fuel pressure test on 2009 chevy cobalt

There is a shrader valve on the fuel rail. You can hook a guage to it and cycle the fuel pump with the key. Shrader valve looks like a tire valve stem. Should have a plastic cap on it and most are on drivers side.

My 1990 olds cutlass supreme will not stay running it has fuel and has spark. It will start then dies immediately. Any tips has brand new fuel pump

It could still be a fuel problem. The only way to be certain is to put a fuel pressure tester on it. Autozone may rent or loan fuel pressure gauges. Easy to hook up to the shrader valve on the engine fuel rail and test fuel pressure. With key on, pressure must be over 40 psi, 40-44psi is what is called for. If pressure drops below 40 after it starts, then you know it was a fuel problem. Either the fuel filter is clogged, or the pump quits because the oil pressure switch is faulty. That switch is tied into the pump circuit, keeps the pump running after the engine is running.

If fuel pressure stays good, maybe problem is in the ignition system. Have the Ignition Control Module tested, also the crank position sensor.

My 1996 Jeep all of a sudden just quits while riding down the road and oftentimes backfires.

you are going to have to check for fuel pressure, usually cars only backfire when they are running lean. Push in on the shrader valve on the fuel rail, and have someone crank it for a second to see if you have fuel. Also check for spark.

Im trying to che ck the fuel pump under the hood by a hose going into the motor. which hose would i be looking for? i have a 2000 dodge stratus.

You should have a shrader valve that you can hook up a gauge to. If you dont then even if you have pressure by opening a line you wont know if its enough. . Also if you find the shrader, should have a cap on it, cycle the key and then push the shrader in. If no squirt then the pump isnt working. It may be a bad pump or it may have lost its power source. Could be a fuse or broken wire somewhere

99 gmc safari van,wont start,no fuel pressure to the filter

Do you hear pump cycle (hum) when you turn key to on position?
Take air intake hose of front of throttle body & spray WD-40 inside throttle body with plate open for a couple of seconds, then see if it will start & run for a second or 2. If it fires up for a short time, it is fuel related problem. Perhaps autoparts store lends or rents fuel pressure gauges, which will confirm if pump is working or not.

03 Chev 1500HD Ran out of gas. now wont start

I had this same problem and first i took it to the chevy dealer and they charged me 2500 bucks to change a bunch of stuff that didn't fix the problem this included the starter and O2 sensors and a computer board. To say the least i feel like they took me to the cleaners and didn't fix it anyways. The same problem happened again and i took it to my local mechanic and he said all it was, was a 20 amp fuse under the hood and charged me 10 buck to fix it. I'm not sure which fuse it was. But i would start there.
