your 93 cavalier may have a fuel line blockage which prevents the fuel from gettin to the engine. first i would take off the fuel line to the injectors then have somebody crank the engine for like 2 seconds and if the fuel doesnt spit out of the fuel line or barely comes out then you have a fuel line blockage!
check your fuel pressure with a gauge and make sure its within specks, if its low, could be your regulator,
another option is your crankshaft position sensor, if this little unit is done, you get what u got!
you can check your fuel pressure without a gauge,on the fuel rail there is a release valve, looks like a bike tire valve, pop the cap, with safety in mind depress the stem, to c if fuel comes out, member this should b under pressure and may spray, now turn the key to the on position, listen for your fuel pump to kick on , then depress the fuel rail valve again, careful you dont want a gas bath!!!find out from a garage how much the pressure should b and use common sense, lil pressure lil fizz, big pressure big squirt!!! !!!Plugz!!
Not getting fuel or spark?
Possibly the crank sensor or the coil pack is dead. But with a dead crank sensor you also get no spark, no crank. No crank equals no fuel delivery.
i need to find location of fuel filter on 1993 Chevy cavalier
car has spark and fuel it will crank over but will not start
If you mean will crank, but no fire, then check for spark and fuel. If you mean will not crank, then check the wiring and the starter.
A BAD CRANK SENSOR WILL CAUSE NO SPARK AND NO PULSE SIGNAL TO FUEL INJECTORS a bad ignition module will cause no spark its located under the ignition coil trio pack
A 2003 Chevy Suburban will crank but not start if it has no spark or fuel. Checking for a clogged fuel filter or fouled spark plugs can help to resolve the problem.
Does it crank? do you have spark? fuel?
Crank position sensor could be the problem. Worth looking into.
No but, if the crank sensor goes bad you lose the fuel pump and spark.
Your missing spark or fuel.
Does it have compression, fuel, spark?
No, it is needed for spark and fuel timing.
the crankshaft pos sensor controls the relay switches which operate the fuel pump and the electricity supply to the coil causing no spark to reach the distributor YES
The fuel pump is located in the gas tank.
Check for spark by removing one plug; place it back in plug boot; lay on metal surface; have assistant crank engine; look for spark....... but I would suspect a fuel problem. GM has had their share of fuel pump problems; replace fuel filter; it is underneath car on frame under drivers seat then recheck starting; My guess your in tank fuel pump is on the way out... have it pressure tested......1930fcoupe
I'm thinking crank sensor.
No spark? No fuel?
Behind the gas tank.
Check to see if engine is getting fuel and spark
Timing chain is gone buddy
You need three things for the engine to run, compression, fuel and spark. You say you have fuel now check for spark.
Many possibilities. Fuel flow problem (fuel pump, clogged line, fuel injectors) Contaminated fuel. No spark or weak spark (bad plug, wires, electronic ignition module) No air flow (Clogged intake, clogged filter) Bad timing belt/chain (I can't remember which one a '93 has).
Have you checked for fuel and spark? Camshaft sensor and or crank sensor will cause that problem as well!
compression? bad/worn/broken timing chain..
