Hi, I have a chevy 1999 silverado 1500 4.3 v6. I just replaced the fuel pump, new fuel filter and a sensor up by the injectors/carb., and still at times it wouldn't start. It would turn over but not start, a gas issue and maybe when it was cold. So I replaced the fuel pressure regulator. Well I can't get the metal gas lines to stay in place when I reinstall them back into the top of the spider assembly unit. I did notice there is a plastic sleeve and a metal washer and 2 o-rings inside the fuel port where the metal fuel line are inserted.

What is the proper way to install those 2 metal fuel line into the fuel ports on the top of the spider assembly unit? Plus how do I get those 2 plastic sleeves out of the fuel port they are down in there tight! Thanks.. Also there is a retainer clip that holds the lines down but it doesn't hold them down enough yet in the my case cause they leak fuel when I start the truck up.

You will need to do a fuel pump pressure leak-down test, the pump must not loose more than 5 PSI overnight, u will need a cheap fuel pressure test guage, the test port is on the fuel supply rail to the injectors on the intake manifold, it looks like a tire valve but metal with a plastic cap on it, u may be able to borrow this guage from Kragen, Autozone or a parts store like them, if not they are very cheap, less than $20 US. Run the engine with the test guage hooked up, turn off the engine and then check it in an hour or so, if it drops more than 5 PSI then u will need to replace the fuel pump in the gas tank. One note make sure the connection for the guage is tight with no leakage or the test is invalid. Please rate this solution.

Check your Fuel Lines and your Fuel Pump. (I just fixed a problem with my 2001 Isuzu Rodeo Fuel Return Line).

Also remember that in Rodeos, as soon as you turn your car key to turn the ignition on (just to make the dashboard lights go on) a certain amount of gasoline gets pumped to your engine in preparation of you turning the key all the way to crank the ignition and start the car. In other words, even before you turn the key all the way to crank the ignition, the Fuel Pump will pump some gasoline through the Fuel Lines to your engine (it will pump the gasoline for about 4 seconds then stop). So when you go to start your Rodeo, remember to turn the key with one continuos motion so that you start the ignition cranking while the gasoline is being actively pumped.

In addition, you should never turn the ignition lights on without turning the key all the way to start the engine. Doing so could cause that bit of gasoline that was pumped to start the engine to just sit there and create problems.

1991 ford bronco fuel pump wont shut off


The fuel pump should turn on for about 3-5 seconds when you turn the ignition switch to on. If the engine starts the pump should still continue to run, if you do not start the vehicle the pump will shut off. It sounds like your fuel pump relay is stuck. Sometimes they will stick on even with the key off. The relay should be located in the relay box, under the hood on the drivers side on the inner fender well. You can try tapping on the relays with a end of a screwdriver, etc. See if that does anything for you. If that doesn;t help I will have to look up some info. Been a while since I had issues with that .

1988 Trans Am will not start when ignition is turned all the way.


Take a test light to the small wire on the starter and have someone turn it to the start position. If the light lights up and the engine doesn't turn over, I would suspect the starter itself. If the test light doesn't light, try it in neutral and repeat test. If it still doesn't light up, it may be the PRNDL switch or the ignition switch itself.

My key doesn't turn in the ignition, its automatic and the shifter and wheel wont move either. Everything is locked how do I unlock it? help pls?


If turning the steering wheel to the left or right doesn't allow the key to turn, it sounds like your tumblers in the lock cylinder have failed. Unfortunately, there is no way to know when this is going to happen, but eventually, it happens. Not a real expensive fix. Replace the ignition/lock cylinder.

If oil pressure sending unit is bad will it stop fuel pump from working on a 2000 blazer


You should never try a pump without it being in fuel. It uses fuel for lubrication when it is running. If the vehicle doesn't start at all when you first crank it over it is not the oil pressure sender. If you just put the pump in you might want to turn the key off and on several times to cycle the pump then try to start it. If it doesn't start then check fuel filter or check fuel pressure at fuel rail in engine compartment. Is fuel pump cycling at all when the key is turned on? There is a problem with ignition switches on some of these blazers.

OK.....turn key ignition on....can hear fuel pump doing its thing.....try to start engine....engine turns over easy....it almost wants to start....like it coughs a bit....but just doesn't come to life....


Get a fuel gauge and check the pressure. Should be around 40. Spray some carb cleaner into intake and see if it runs a moment then you know if you have a fuel related problem. Reply mine has 310,000 miles on it.

My 94 Taurus will not turn over. Lights work...I replaced starter then ignition switch. Car will not turn over. It has a history of intermittent starting problems. It may or may not start. Now it...


They have a bad ignition problem. Its more than likely the ignition. Turn the key on, Then right below the ignition theres a hole. take a long skinny phillips screw driver and push it up through the hole and you will hit a release for the ignition. Push it up as you pull the ignition out. Then try to start the car with a flat head screwdriver. Write back if that doesn't work but i have a feeling it will.

My 2004 Pontiac Grand Am ignition switch all of a sudden with the key will not turn on or turn at all for that matter this has not happened before Why ?


It sounds like your telling us the key won't turn in the ignition anymore for some reason. If that is the case the problem is one or more of the tumblers in the ignition have fallen, if this is the case you will have to replace the ignition itself or at least the ignition core. If you mean the key turn but the vehicle doesn't start I would start by disabling the alarm system you installed to eliminate the starter kill switch as the source of the problem. Also, if this is the case try jumping the vehicle. If it turns over and starts with a jump your problem is the battery having a dead cell in it. It can have all the world but if you have a dead cell it doesn't have the amperage to turn the starter over.
