Question about 1996 Chevrolet Blazer

1 Answer

The truck will not turn over if I put gas directly in to the air intake it will start and run fine I can restart it but if leave it off for a couple hours it will not turn over. originally I had a check engine light I put it on the computer and it gave me a code for MAF low I believe so I cleaned the MAF and have not had this code reappear so I?m guessing it?s the fuel pump Thanks in advance for your help

This sounds like you are losing the prime in the fuel pump. I would hook up a fuel pressure gauge to the fuel rail and after running the car, shut it down and see if the pressure drops over time. If the fuel pressure drops then replace the pump.

1991 ford tempo ran fine went to store it started fine and then just died

Likely a gas or spark problem. Spray starting fluid into the air intake while cranking it. If it then runs for a few seconds, it's a fuel problem-maybe the fuel pump, filter, or injector circuit. Check if gas is getting up to the engine.
Buy an inexpensive "spark tester" at a parts store, and check for spark- if no spark, the ignition circuit will need diagnosed- could be the ignition coil, maybe the electronic ignition module-several possibi9lities. Let me know what you find, or if other questions..

sometimes when you run out of gas you can pull up the dirt fromthe bottom of the tank and damage the pump one quick way to see if you have a pump or filter problem is to put gas directly into the carbuerator or throttle body if fuel injected you can try spraying starting fluid into the air intake also try heet in the fuel tank i hope one of these works for you also to make sure your fuel pump is running you can take off the gas cap have somebody turn the key to on (not start) and put your ear by the tube to hear iif the pump hums or runs this primes the prior to starting good luck

I ran outta gas on my 1998 chevy silverado v.6 vortec. i put more gas in it and pumped the accelerator a few times and it still wont start. how can i fix it is it simple

Best way to fix it when you run out of gas is this. Because you ran out of gas, means your fuel filter is out. When you run out of gas, you end of getting like a air blockage in the line. Now, professional way is to take fuel filter off and fill with gas and put back on, BUT i will tell you a back yard mechanic secret way. Is get a can of starting fluid ( you can get at any auto parts store) and while someone is in side the Pickup, have them ready to turn the key. You are outside with the hood up, and you will be spraying a little bit of the starting fluid in the air intake of directly in carb area ( if carborated) but just spray into air intake. Have them crank the engine, at same time you will spray starter fluid in air intake, just a couple of quick sprays. You will notice it will start and maybe die again. That is normal, you might have to do this a couple times to get things flowing. HOWEVER, what normally happens when you run out of gas, the fuel filter picks up all that junk that has been gathered in the bottom of fuel tank and it has clogged your filter. FOR SURE, if you replace your fuel filter, it will solve this problem. Thank You, and I hoped this helped you.

On my 2000 monte carol something attached to the top engine disconnects in two places when you try to start it... when you try to restart it it turns over but stalls out as soon as you leave off the gas....

Sounds like you have a bad motor mount , and the intake tube is disconnecting... causing air movement acroos the mass air flow meter to be reduced and thus cause the engine to enrichen so much your engine gets flooded...

Check the motor mounts... and the clip that holds the intake tube together... let us know if you need any further input

My ml320 v6 1999 sometimes runs badly and idles rough. if i turn off then on she will run fine but then next time the same. i have recently fitted a new air intake system.....someone suggested...

You can try disconnecting battery, but make sure to reset the computer on first restart by turning the wheel each way fully a couple of times.
Also another thing to consider is the Crankshaft position sensor, these start to fail but do not throw an engine computer code and after a while will not let the engine run.

Car won't start without adding gas to air intake then won't idle

Check the fuel filter, you may have clogged it when you filled the tank.
