Might have to replace Distributor pick up coil. Did you check to see if it had spark when you try turning it over? You can pull a wire off and either use a spark tester which is about $10.00 at the parts store or use a paper clicp to bend it and put it in the spark plug boot and touch on a metal objcet while turning the engine over. Could be the Idle air control valve, try unplugging MAP sensor. Did you see if you have moisture inside of your distributor cap?

Your Question:I was driving my 95 blazer on the freeway and it felt like it was running out of gas fuel was low but not out I got off the freeway it died at the stop sign and it and has not start senc

You could pour a little fuel at the intake. But, in order to know for sure you need to check for correct fuel pressure and volume. Check to see if you have spark at the spark plugs, also. Need to diagnose properly to save from having to buy anything you don't need to buy.

disconnect the fuel line at the fuel filter or the fuel rail which ever is easier to get too, then try to start the car if it sprays fuel it is not the pump if it does not then you know it is the pump.

Engine dies instantly on freeway

There are many things that will cause a vehicle to quit. Lack of fuel and lack of spark are the 2 most common problems. A few possible issues here. Fuel pump, fuel filter, open wire circuit to the fuel pump, bad ignition module, ignition coil, distributor pickup coil, open wire circuits in ignition, relays. Need to eliminate either no fuel or no spark first then go from there.

I have a 1985 Chevy C/30 pick-up with a 7.4L 454. Truck has been running fine and about a week ago I was driving down the freeway and the motor backfired and and lost power and eventually died. I stopped...

85 with TBI only needs 13lbs of fuel pressure. verify that the fuel filter is clean. there is no easy way to ck fuel pressure, special adapters are needed, I dont have info here at home but there should be a relay for the pump, on the firewall and the oil pressure switch also powers the pump. did you replace the pump trying to fix this problem or did you just mention it to help troubleshoot the problem? verify that the fuel pump wiring has a good ground, should have been a eyelet that bolted to the frame..when you initially turn the key on, you should hera the fuel pump power up for 2 seconds, then go off, after the engine starts, the power for the pump goes through the oil pressure switch.

I have a 99 jeep grand cherokee and i put gas in it and drove a 1/2 mile and it stopped accelerating and would not start for 20 minutes now it will start but could this be the fuel pump? All of the...

Cant say if its the fuel pump but how a filter works is when the flow stops the sediment will settle off the filter. If enough sediment is in the filter you will fell power loss after driving for awile.Now if you werent having issues before this doing freeway speeds or gunning it around town I wouldnt suspect a filter from just driving around town. If it were a filter on a vehicle your age it would set a check engine light for running lean,
Now its pretty typical for a fuel pump to stop then work later when it cools off.
If your still experimenting look at the fuel pump realy under the hood in the fuse box and if you have a lookalike like a the horn or ac relay then swith one with the fuel pum relay.

02 yukon died on freeway electric problem or fuel

When you said checked the fuel filter, did you mean changed the filter?? And does the Battery hold 12 volts?? Check the battery to make sure it has 12 volts. If you have a second car, take the alternator off and bring it to a auto parts store like Auto Zone and they can test it free of charge and battery too. Change the fuel filter, if both are good then check all the fuses and relay, Pay attention to the fuel pump fuse and ECM fuse. If everything has is good then it's going to be a bad fuel pump, which is located in the gas tank. That requires to dropping the tank to get to the fuel pump. Good luck and hope this helps.
