How to change fuel pump in a 2000 Pontiac firebird


If the car starts and is not staying running I do not think it is the fuel pump. It is either your idle air control valve not allowing enough air to get into the engine as they can get clogged pretty easy with carbon. Or it could be your throttle position sensor not functioning correctly. The first one can be cleaned with regular carb cleaner and that may fix the problem,.

I have a 1986 GMC 1500 with a 5.0 and stock rochester carb. The truck will start but you must keep gassing it as it won't idle. It kicks off every time. Any suggestions on how to fix this cold natured


fast idle speed screw, works off the fast idle cam which the choke adjustment sets, it works together by linkages. This is the raised idle speed setting you need to keep a cold engine running. First you set the idle speed by the idle speed screw with engine at normal operating temperature. Then you set the linkage up so the cam is on a raised step, throttle will be held on that raised step. then you can turn the idle speed screw to get idle at about 1500-1800 rpm. Now when you start engine cold, choke will set the fast idle cam on that raised step- when engine starts and runs it should be running at your fast idle setting. That's how it supposed to work, you just have to get everything adjusted right. I hate carburetors, they never stay adjusted right. Considering their complexity and small mechanical parts, no wonder.

88 rx7 run but wont start


The FC3S is notorious for this and fueling issues. Check all ground points, battery cables and connections. Check the draw from the starter. If the voltage drops below 10V there is not enough power for the ignition, causing weak spark. It really needs to spin over 200rpm cranking. Pop starting does not necessarily mean the compression is good. You need to make sure it cranks fast enough to get a proper compression test with rotary tester, New NGK plugs, new NGK plug wires.

Did an engine tune up on a 1975 dodge v8 360 2bbl engine the battery does not keep enough charge to turn over and stay running


Is the charging system working? With the engine running at a fast idle and a voltmeter connected to the battery you should see readings of 14-14.5 volts.

89 dodge shadow. hard start. normal idle cold, fast idle warm. sometimes it wont start until i hear fuel pump activate.


Hello,
The car may be hard to start because it may need a normal tune-up. If the spark plugs are pretty used, they will slowly stop burning as much fuel because the spark slowly gets lesser and lesser. On a cold day the fuel is harder to ignite with a small amount of spark.
Normal idle when its cold means that your cars idle is probably too high. If you lower the idle, the choke on a cold day will keep the idle a little higher until the motor warms and then it will kick back off. If the idle is too high, it will run very rich, smothering itself with fuel, and causing the idle to stay low. When the car warms, its creating better spark when its warm, and with the idle being too high its running at a fast idle.
The car wont start sometimes can be the cause of a few things. If the ground is bad on the fuel pump, it wont make a good connection sometimes for when you turn the key on, the fuel pump dont pump the fuel to the engine. Another one can be that your accessory switch can be loose going to the fuel pump. I think its your ground though. Good luck! Hope this helps.
Have a nice day. -Steve

Wont stay started


Make sure there are no broken hoses on the intake manifold, or anywhere else under the hood. There are many hoses of many different sizes to be considered,, so check them all. Listen for rushing air, or a whistling sound. If you suspect an intake leak, briefly spraying small amounts of WD-40 ( without the long red straw attached) at a leak will change the speed of the idle....this would indicate that you are on the right track. A leak would cause a high idle, but maybe not enough power to keep the car running under load at low speed. As unwanted extra air is introduced into the manifold from any source, the fuel mixture can get leaned out causing a higher idle and a loss of power. Good luck.
