I had the harmonic balancer and serpentine belt on my 1998 Malibu 3.1 V6 replaced a few weeks ago. I was
able to start the car an average of 7-11 times during an average day without any problems after the repair.
Then one morning the starting was a problem. It took several tries and giving a little gas to stay running.
Usually the turn of the key, and it would fire up and stay running as it should without the need to pump the gas.
My question, is it possible for the "crank position sensor" to become positioned wrong or become off aligned ,
yet still start up right for a few weeks? Thanks for any known answer.
|Highly unlikely the crank sensor position was changed. It is
possible the wires to it got disturbed. Have had a few with broken
wires near the senor. May just have carbon on the throttle plate,
in the idle air valve, or a leaking fuel pressure regulator or weak
Ok my car is turning over but will not start every once in a while I can get it to start for about two days I'm
thinking maybe the crank sensor I have a lot of anti freeze that is leaking all over that side of the engine my 98
Chevy malibu could the antifreeze leaking have anything to do with or is the crank sensor bad.
|The antifreeze should not be getting into the crank position
sensor. You need to check fuel pressure, and if you have spark
and fuel injector pulse while it is acting up. There are too many
things that can cause a no start condition and these basics need
to be checked first.
car cranks but wont start.
i took my 1998 chevy malibu to auto zone to get scanned
because my check engine light is on. The code was p0336,i was
told the crankshaft position senor was the problem. They told me
to check connector and wiring to senor, check trigger wheel for
OK my 1998 malibu v6 3.1 is doing the same thing, it will start sometimes right off and others it takes like 10 to
15 min for something to click on and it works. I got the ignition switch replaced because the mechanic said that
was the problem. Worked for a month and now back to the same thing. Now the mechanic says its a fuel
pressure regulator but the Autozone man thinks its a crank issue. Any ideas?
|If it does not crank over for 10-15 minutes, then it cannot be a
fuel pressure regulator (FPR). Could be a bad started. If it does
crank over, then could be many things- crank sensor, ignition
module, fuel pump, computer, etc. If the security light is on the
dash, may be a bad Passlock sensor- which is the ignition
cylinder- this is different from the ignition switch.
My 98 Malibu is having a no start issue. Got it scanned and no codes come up. I am not getting any spark
from the wires going to the spark plugs so I believe it might be a relay or the Crankshaft Position Sensor. I
could be wrong, I watched some videos saying that the passlock system may be the issue. I haven't had a
chance to check it out because the car is not at my home. If it is the Ignition Lock Housing that can go bad and
make the Passlock faulty then I may have to change it DORMAN PART #924-702 and reset the system to
accept the new Ignition Lock Housing Code. Any Ideas?
I forgot to mention that the engine does turn over but will not start. My comment was about the Crankshaft
Position Sensor. Ignition Lock Housing Passkey Issue. DORMAN PART #924-702.
Passkey Sensor is fine. No sparks to the spark plugs. :(
|The theft system disables fuel, not spark. You need to look at
that system, not the theft or security.
I also have a 98 Malibu that got the P0336 code for the crankshaft position sensor. Seeing as how there are
two sensors, is this code specific to a certain sensor, or do both need to be replaced?
My car was running fine until the day before yesterday it would not start we ended up getting a jump and it took
about 25 min before it started the next day it was fine all day when I had turned the car off and was just
listening to the radio for a few minutes went to go start it and the car wouldn't turn over. This time when we got
a jump it did not work... What do you think the problem is..?
|Simple, you have a bad battery.
i have a 1999 Chevrolet Malibu and i took it to auto zone to get it scanned. The code read crank sensor a
faulty. My question is which is a? I replaced the balancer and its been acting up since. It cranks but have to
give it a little gas and sometimes when driving and trying to make a pass it dont accelerate i have to ease off
gas and it slowly speeds up and when i get it cranked and let it idle it act like it want to cut off and sounds like
something fighting n the fuel tank. Can u help me please!
|What is the code number retrieved from the computer?
I have a 1997 Malibu, the other day it started and drove then just stopped while i was at a light. I had to restart
the car and drove a little and stopped again. Has new battery, full tank. Got it to the drive way it starts up but
when it is driven for a little while and at a light it will shut off. It doesn't idle or anything just shut off. Any ideas
what this can be, I am able to crank it and start it and it starts up but as soon as I attempt to drive it will shut
|Sounds like a bad ignition switch or ignition module. The switch
supplies power to most of the cars electrical systems. The
module controls spark to the spark plugs.
I have a 2000 Chevy Express 3500 that just died while driving.I replaced the cam sensor cap rotor button plugs
and spark plug wires. Now it turns over won't start. When I do try to start it will turn over good then drag down
then go back to turning over. Someone told me it was the crank sensor. Any ideas??
Yes, i could be the crank position sensor. Scan the computer for any codes and watch the RPM while cranking.
I HAVE A 1998 MALIBU, I HAD IT PUT ON THE MACHINE AT THE CHEVY DEALERSHIP AND THEY TOLD ME
THAT THE IGNITION MODULE,COIL PACK AND THE SPARK PLUG BOOT WAS BAD. I REPLACED ALL OF
THEM NOW IT SOUNDS LIKE THE STARTER IS GOING OUT IT JUST SPINS WHEN YOU TURN IT OVER DO
ANYONE HAVE ANY IDEA WHAT'S GOING ON.
My 1998 Chevrolet Malibu doesn't crank when i turn the key.
Who's right in this scenario?
Have a 1998 Chevy Malibu 6cyl. 4 speed.
The other day it over heated and stalled in the middle of a busy street. After about 45 minutes I tried to turn it
over. No problem.
We took it to a mechanic and who claimed it needed a new crankshaft relay (I'm guessing he meant position
sensor) Supposedly he replaced the part. We honestly have no idea...he won't give us the old part back or
anything. He told us right before we drive away. Oh by the way you need to keep water in it because you have
This morning before I left I put antifreeze in it and lull and behold after the engine ran for about 20 minutes, car
started overheating. Thought I'd try turning on the heater to see if it was just a simple thermostat issue. Sure
enough car's running red and no heat coming out of the heater.
Now he's claiming it's a water pump issue. Am I the only one thinking that there is an issue here? Can this
sensor cause these problems? I've personally not heard of that before but I could be wrong. Help.
|You have a blown headgasket. That is why the engine is
overheating, but you do not get heat from the vents. This causes
air pockets in the cooling system. The heater core cannot
transfer heat from air via the heater core. It must be coolant
without any air pockets..
|I have a 1999 Malibu. Love the little bugger but crank, crank, crank. Takes 30-40 sec. to start. For what ever
reason it (seems) to start better some times with a little pedal. Whats up with that.
|Check the throttle sensor and clean the throttle body plate and
bore real good. Change brands of gas.
|1998 Chevy Malibu won't start. I replaced crank sensor, coil pack and module. Could not get plug to fire when
trying to crank the car can you help me.
|Did you check all the fuses? Do you have crank RPM on a
scanner/ If not, check wiring from crank sensor to ignition module
for being burned on the EGR valve.
|1999 malibu cranks but won't start sometimes have no codes and see rpm on scan tool. Pulled the front three
plugs see no spark just as you leave off the key you'll see a spark. Put plugs back in starts right up. Have no
flashing anti theft light comes on and goes off. Have replaced the 3x crank sensor and ohm tested the wires
from the crank sensor to the ignition module. I have replaced the ignition switch fuel pump and filter, plugs and
wires. I also took the ignition coil to Autozone three times to have it checked and it tested good. What do you
think I should do next. Thank You.
|Ok, you say that you put the plugs back in and it starts right up?
If that doesn't happen to be the case, you might want to replace
the ignition module located underneath the coil packs. Also,
check crank sensor wiring for chafing on the engine block, as
that is a common problem. Other than that, maybe check to see
if you're getting a fuel injector pulse. Could be a faulty PCM, or
even a wiring issue.
|i replace the thermostat on my 1998 chevy malibu ls and it is still over heating and has no heat at all and is
giving me problems starting now too. Any suggestions appreciated and thankful for them thanks Lori.
|Look for the radiator fans to come on. If they are and there are
bubbles in the coolant, you have a blown rear head gasket.
|Cranks, but no start. Fuses and relays are good. Gas is being pumped when key is turned. No spark from
wires. Car cut off while driving now no start period. Don't have a scanner, engine light is not on. Someone
damage ignition cylinder during an attempt to steal it. Could it be the ignition switch even though when I turn the
key I'm getting fuel delivery? Or ignition coil, or ckp sensor?
|Is the theft light on? Yes, the ignition switch could have been
damaged, or wires around the ignition switch.
|I have a 1998 malibu 3.1 rips like crazy love it but my issue is when your foot is just touchin the pedal it starts to
hesitate and at a light it stalls usualy when its busy as hell any help or ideas will be appreciated
|I have a 2003 Malibu 3.1. Engine starts ok when it is cold and runs normal. When the engine warm it only starts
after 30 40 seconds cranking and runs ok. Any help or ideas will be appreciated.
|Check for low fuel pressure,vacuum leaks or more likely you
have a leaking fuel pressure regulator.
