My 94 Thunderbird won't start until like the 4th crank, then it runs like a champ. It acts like it isn't getting any fuel. Please help!


You may be right on your hunch.
The fuel pump gets power from the pump relay for 3 seconds when you turn the key on, then no power until the engine starts. If the fuel pressure is low it could take several trys to get the pressure up to normal and the engine start.
A mechanic would check the pump relay and the fuel pressure with a gauge before and after cranking the engine.

Keeps stalling out


If it starts fine and idles fine but then stalls or doesn't have power when you juice it, it sounds like a fuel problem. It is unlikely a carb issue if it gets regular use and as long as its not sitting for long periods of time. I would first check the fuel filter. If that's fine, then I would check the vent hole on the gas cap (if you have one). If it is a gravity-fed fuel system and the vent hole on the gas cap is clogged with dirt, dust, and debris, then the gas will not flow to the carb fast enough and you'll get a very lean mixture. Sure, it will idle fine because the engine isn't demanding much fuel at idle, but when you open up the throttle it will stall because the air:fuel ratio will be too high (symptomatic of a lean mixture) Last thought: Dirty air filter Let me know if this helps

Turns over but won't fire


If a starter is able to crank the engine but it won't start you usually have either an electrical or fuel problem. It's also remotely possibly that it's compression.If an engine has proper fuel, spark and compression, it will start when you crank it. So your challange is to find out which part isn't working right. Start with fuel. Spray a little starting fluid into the air intake while someone tries to start the engine. If it starts briefly when you're spraying starting fluid, you probably have a fuel delivery problem. That could be injectors, fuel pump, fuel filter, relay, fuse... who knows what until you check into it.If it doesn't start with starting fluid, check the spark. Pull a plug wire and attach it to a spare sparkplug and set the plug on a solid metal part of the engine. Have a helper crank the engine while you watch the plug. If you have a good spark, it might just be out of timing.In any case, you'll need to start isolating the problem. Find out which part isn't working then you'll know what to replace/repair.

Starting problem, motor cranks but won't turn over


A common fault is air in the fuel system caused by a fuel pump failure or just a simple pin hole in the fuel pipe allowing air into the fuel instead of fuel.

I Have a 2006 pontiac G6 gt with the 3500 engine, The battery was removed positive side first and now after it was replaced the fuel pump isn't working, everything else seems fine but the pump...


You can't fix it yourself. It takes a scanner at your Local Dealership to do it. People do it, (new battery) everyday unaware that doing so can and usually does, arm the theft system and either kills the radio or the whole car. To me it's just another built-in defect that requires dealer assistance. It's a buzzkill I know, and it probably won't be long until car owners won't even have access to the engine compartment. Sorry.

I have a 1998 Chev Monte Carlo SS, The engine turns over but doesn't start. It seems to not be getting fuel but am not sure.


disconnect the hose that goes into the fuel injectors rail, put it into an empty coke bottle and ask for a friend to put the ignition switch in the on position. if there isn't gas going into the bottle, then you should check for the fuel pump relay and if it's ok then check the fuel pump. Check the fuel pump fuse too.

My 1999 masda 626 won't start. it turns over but acts like it isn't getting any fuel.


check relays/fuses first then the pump if you know how to test it
the pump is easy to test locate any fuel line unplug it tell a friend to make a quick one key turn if squirts fuel then pump is fine
but check the pump relay first to make sure and to begin with simplest
it seems you can tell it is the pump but you don`t know where to start
