Question about 1994 Chevrolet Cavalier

Replacing fuel pump in 94 Cavalier

My 94 Cavalier is cranking but won't turn over. I've been told I may need a new fuel pump. I just have a feeling that it may not be the answer. Are there other causes for this? If I need to replace the pump, can I access the gas tank under the back seat? It was very cold when this happened last week so I plugged in the block heater. It started about four hours later and ran fine for a week. Yesterday it wouldn't turn over again and plugging it in hasn't helped. Could the problem be a blocked fuel filter? Can a diagnostic test determine where the problem lies? I want an easy on the budget solution if possible.
Thanks!

If you haven't changed the filter in a long time change it. Diagnostics are very helpful but I'd change that filter first (you are not wasting $ if you have not done it because it is likely due for a change) With the key on, can you hear the pump running? If you can, that's a good thing.
good luck and post back if it works (or not)

94 olds silhouette new fuel pump still won t run cannot hear fuel pump ?


Is it an 94 or a 2004 Silhouette.You should hear a fuel pump when turning on the key (anytime after the key has been off for about 10 seconds) or whenever there is oil pressure.
If there is no fuel pump sound or fuel pressure when the key is turned on (this is the prime cycle) then crank the engine for at least 10 to 15 seconds to get oil pressure as this is the 2nd source of power to the pump and what powers the pump when driving.
Still no pump running?
Check fuse /wiring/connections/including ground.
Lastly..... New fuel pumps don't always work just because they are new,

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.

94 gmc sierra 4.3 v6 manual, won't turn over, can hear fuel pump start when accessories turned on..won't fire, girl who needs help


The first thing I would check is fuel pressure. This type of fuel injection requires a minimum fuel pressure in order to operate. If fuel pressure is as little as one psi below minimum the vehicle will not start. You can try squirting a couple of shots of carb spray into the air snorkel while somebody cranks the engine over. If the engine starts and then dies you now you fpdeffinetely have a fuel issue. If the engine still won't start check for spark. Let me know what you find. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

94 Yukon cranks but won't start on cold mornings.


I hope I can help you with your question I believe I can first and foremost if you're having trouble starting your car on cold mornings it's probably going to be a clogged fuel filter or bad fuel pump about to go out you're having symptoms as you described and then whenever you're at 55° things start to warm up and you can start your car okay the filter is so clogged up imagine that look looking like a blood vessel okay when you have a clog in it it doesn't allow the blood to flow freely feel the same way

Changed fuel pump i put a new battery in changed fuel relay switch and still wont start spryed startin fluid in air hose it will crank and imediatley die? what do i do i have tried everything people...


is the security light flashing when the key is turned on? if so you have a security issue and not a fuel pump problem. the ECM shuts off the fuel injectors so the car won't start. the ignition fire is still good so the car runs on starting fluid. check the light and then email me with more info.

I have a 94 chevy cavalier. and it wont start. the coil is fine and so is the spark plugs. and it does turn over when i crank it... i would pump the gas a couple of times and it would seem to try and start...


you need to check see if it is getting fuel sounds like a clogged fuel filter and when you pump the fuel peddle you are puttting it clear flood mood which may also be leaking fuel injectors and flooding the cylinders with fuel but most likely is a clogged fuel filter try spraying starter fluid in throttle body and if starts its clogged fuel filter
