Olds 1988 cutless ceira 80 of time it wont start unless you spray a shot of starting fluid the other 20 it will start some times it run irratic and some times it wont can you help you?

INSTALL A NEW FUEL FILTER FIRST. IF THAT DOESN'T WORK CHECK FOR FUEL PRESSURE WHEN YOU TURN THE IGNITION ON. THE PUMP RUNS FOR 10 SECONDS AT FIRST TO BUILD FUEL PRESSURE. IF NO PRESSURE IS THERE AFTER THE PUMP RUNS FOR 10 SECONDS REPLACE THE PUMP.


If you are getin gas an fire but still wont start why?

Don't know what your vehicle is but if it is fuel injected, it may have some fuel pressure but if it doesn't have the required amount of fuel pressure it isn't going to start. Do a fuel pressure test, you may have a bad fuel pump or bad fuel pressure regulator. Also check all the fuses. Also check the timing belt if it has one, it may have jumped or broke.

How to determine if fuel pump is working on 1988 Pontiac 6000.?

Get a can of throttle body cleaner.....spray throttle body cleaner into the throttle body.....open the blade and shoot some into the throttle body. Then try to start the car...if it starts, then you have a fuel delivery problem. Hook a fuel pressure gauge to the fuel rail and just turn the key on and see what pressure you get. If no pressure then it is either your fuel pump OR a clogged fuel filter. You can then put a new fuel filter on, test the pressure again and if still no pressure, you are pretty much looking at the fuel pump. If you get fuel pressure at the fuel rail and it still won't start then you probably have an injector problem.

Fuel pump is bad.


Why would a 92 Chevy blazer not start while getting fire and fuel coming out of the fuel pressure release when checked?

You may have some fuel pressure but not enough. Do a pressure test with a fuel pressure test gauge, it should have 41 to 47 psi to properly run the engine. Sorry, But that engine should have 9 to 13 LBS. of fuel pressure. No lower are higher are you will have problems.


When cold you have to pump accelerator many times before it starts What could be the problem?

pumping probably isn't helping if the truck has fuel injection. extended cold crank times are often caused by a bad cold start injector or the control for the injector. also if there is no fuel pressure (i.e. a fuel pressure regulator that is leaking back into the tank as the car sits), it will take awhile to start.

How do you install a new fuel pressure regulator for a 88 ford bronco 302?

Remove the fuel pump and relieve the fuel system pressure. Disconnect the fuel line then fix the fuel pressure gauge. Reconnect the fuse to the fuel pump and start the engine to check leakage. Tidy the surrounding of the fuel pressure regulator.


1996 4runner will turn over but not start try again several times it will start?

Most likely a fuel issue. Hook up a pressure tester on the fuel line and test it. It should come up to pressure immediately. If it takes a few seconds or longer then something is wrong.


2000 grand am and lately its been really hard to start it starts but it takes forever and when I'm driving at times it feels like something is pulling it back What could be the problem?

It could be a partially blocked air filter, fuel filter, fuel pressure regulator (if your vehicle has one) or low fuel pressure. Use a fuel line pressure gauge to see what the pressure is. You may need to look up the PROPER pressure for your vehicle, then compare it to the actual pressure. If it's low, check the fuel filter and/or fuel pump.

My 1993sable won't start has new fuel pump and new fuel 1ilter new fuel pressure regulator and no pressure on the fuel rail but it will start if you use starting fluid and run fine all day long?

try changing the fuel pressure regulator which is located on the front fuel rail. when you put the new one in make sure you put some lubricant on the o ring to keep from damaging it. Make sure the vacuum hose going to the fuel pressure regulator is good. The vacuum hoses wear/collapse and break - they can start acting up with just a leak and intermittent problem, but ultimately break all the way => no-start.
