Catch?
cranks fast
starts every time.
idles fine hot or cold , or both? hot idle not too fast.
i race engine , in park and neutral, I can hit 3500 rpm easy, can you.
i release brakes, (brakes are not packed in ICE , are they?)
I select 1gear or reverse (A/T or m/t)
the car moves or dont move, which is it, my guess catch = no move at all.
I try to drive, i look at RPM and MPH
RPM moves up and MPH track.
track means they both move in a linear progression.
RPM rises and for all RPM increases MPH also increases.
does it?
if all that works then we have an engine power issue.
weak on hills?

Why wont my 1996 ford explorer start it turns over but wont start


You need to determine whether or not it is getting fuel and spark. It needs both to start. Remove one plug wire and hold it close to the engine while someone cranks it over. There should be spark from the plug wire. If there is spark, you will have a fuel supply issue. Possible fuel pump/relay/wiring/fuel filter/injectors not working to name a few. If no spark, possible crank sensor/ignition module/wiring.

Cherokee revs up wont start


Your description is too vague to give specific advise. However, if you are stating that the engine turns over when you turn the key but it wont run, then you want to check a few possibilities. Fuel, Spark, compression. Make sure the engine is getting fuel. Then check for spark at one of the plug wires. Then check cylinder compression. No fuel can be a fuel pump, plugged filter, or pump electrical connection, like pump relay or wires. Spark problem can be ignition coil, coil pack, distributor module, distributor points. Compression can be piston rings, valves, head gasket. This is not everything, but it may help you!

Fuel pressure spark car wont start


code p0341 refers to cam shaft position sensor(CMP)sensor A bank1---range/performance problem===causes--insecure sensor/ rotor---air gap---wiring---CMP sensor.. I would pay attention to the sensor and the possible causes as listed because the timing of the engine is related to the position of the cam shaft. Timing is computer controlled and will not be "off" unless the CPU cannot get a definite position of the piston to set the timing

still could have a fault in crank sensor wiring ,,, you need to plug in diagnostic tool when it wont start and see if you have a engine revs reading ,,, also check if fuel is getting to the engine ,,,, that car also has immobiliser so try spare key to see if problem goes away ,,,,,, wont get codes on that age group unless problem happens when driveing

It was running fine and then all of a suddun its running rough, it wont shift over and the engine light is blinking.. its a custom 2001 buik century. we need to fix the car so we can get back and forfth to...


flashing engine light means engine misfire. let car idle and mist the plug wires down with water, rev the engine up and down and look for little sparks jumping from the wires. and arcing wires can cause problems. before changing any bad wires check the coil packs where the wires plug in the three small boxes on the top back of motor. they are three packs with two wires each. one pack at a time take the two wires off to reveal the coil towers. have an assistant start the motor and make sure the spark goes from tower to tower. repeat on remaining two packs. if the spark goes straight down the tower the coil needs replaced. if there is no spark, the coil needs replaced.

Hyundai Accent intermittent jerking


Revs.
As for the issue of the idle revs, that's perfectly normal. When it's cold outside, every car is supposed to have a higher rev in order to warm up the engine quickly. In more advanced cars, the computer wont even allow the engine to shift into overdrive when it's cold outside in order to avoid extreme engine stress and damage. When it's warm outside, the engine doesn't need to idle high because the engine is already at a good operating temperature. Not much will be needed to get it to the right temperature.
Intermittent Jerking

There is a long list of things that could cause intermittent jerking. I'm going to name all of them for you, but your best best would be to go to a mechanic and have them do an inspection.
Clogged PCV Valve (Possibly if you don't get your oil changes on time, sign of a tune up)
Bad DIstributor Cap (not likely at 140,000 miles)
Clogged fuel filter (Very likely, usually done with tune up)
Bad Fuel Pump (Not so likely)
Defective ECM (also not likely)
Vacuum hoses/leak (not likely but possible)
MAS (Mass Airflow Sensor--not likely but possible)
Fuel INjectors (if so, sign of a needed tune up)
Faulty Spark Plug Wires (not likely if tune up is recent)
Faulty O2 Sensors (possibly)

Clogged Catalytic Converter (Possible)
~Hope this helps
