Listen for your fuel pump to kick on or the cat could be clogged. You can have some one hit the cat a few times then try starting it. If u turn the key and everything comes on but it still won't start an wont crank over then tap on the starter then try starting it.

Timing chains on 3800 engines do not go bad. The older 3.8 1987 back did. You need to put a crank sensor on it first also check the ign. module under coil pack for green gel that may be coming out of it. Clean the all three battery cables and replace the two bolts too. My 1990 lesabre 3800 has 295000 miles on its timing chain.

What are the symtoms of timing chain failer Does it turn off while driving or motor shakes.


If the timing belt were broken, the car would not be driving at all. If those codes weren't confused with another symptom it could be the car needs a tune up. You should think of when the last time plugs, wires, air filter were replaced. If they're pretty new, it could mean a cracked cam shaft sprocket has the engine out of time. Honestly, a full tune up would be cheaper than paying a mechanic to tear down and close up the engine. Good luck!

1989 jeep grand wagoneer 360 how do i test bad crankshaft position sensor


double posted, now with 360, 5.9L V8 fact.
great.
and has no such sensor.
its a CARB car
with ICM , spark magic box. , NO ECU /PCM brain in car
there for no CKP sensors.. sorry?

if you dont know what is there, photo it and post it
so others can see what is missing or wrong, from factory day 1 build.

i google for you
rockauto shows no such part in 360
alldata.com same
hell. even the 90s the same.
see it here.
all schematics

if engine wont start. even with test fuel, check spark
see the spark section below, under ignition.

http://oljeep.com/gw/elec/GW_wiring-1990.html

the distributor has cam sensor. not crank.
it called today, CMP, cam sensor
this sensor sends signals to the ICM the ICM then makes spark
buy driving the coil,
the CMP is more like Points, simulation, and lasts near for ever.

the 89 4L has a CKP (crank sensor) and is know to fail on brand new cars. (you need to tune it to make work , back in 88/89) at flywheel.
ask me how in know./././??


360 spark
CMP >>>>> ICM>>>> COIL>>> Dizzy cap>>> spark plugs.
this is the chain of events.
the DIZZY does the ADVANCING with ICM. totally. on this car.

2003 kia sedona replaced crankshaft position sensor 6months ago would start again same code plus p0431,0335,0300,o303,0302. replaced sensor still gives a hard code sensors bad. tightened timing belt ,...


first why and how did you tighten the timing belt. if was loose should just replace the timing belt that belt runs the timing.the code po335 is your crank position sensor and it is coming up the engine is fight to keep the timing. replace the timing belt. the codes po300,po302.po303 are for a rarandom misfire. when was the last tune up. change the sparks plugs

DTC P0016 - Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.

The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together. If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 code will set.

Symptoms of a P0016 will or may include:
Malfunction Indicator Lamp (MIL) illumination
The engine may run but with reduced performance
The engine may crank but not start
The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged
The engine may start and run, but poorly

Causes may include:
Timing chain stretched, or timing belt skipped a tooth due to wear
Misalignment of timing belt/chain
Tone ring on crankshaft slipped/broken
Tone ring on camshaft slipped/broken
Bad crank sensor
Bad cam sensor
Damaged wiring to crank/cam sensor
Timing belt/chain tensioner damaged

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.

The crankshaft sensor is part of the primary ignition system and functions as the "trigger".

The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together. If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 code will set.

Symptoms of a P0016 will or may include:
* Malfunction Indicator Lamp (MIL) illumination
* The engine may run but with reduced performance
* The engine may crank but not start
* The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged
* The engine may start and run, but poorly

Causes may include:
* Timing chain stretched, or timing belt skipped a tooth due to wear
* Misalignment of timing belt/chain
* Tone ring on crankshaft slipped/broken
* Tone ring on camshaft slipped/broken
* Bad crank sensor
* Bad cam sensor
* Damaged wiring to crank/cam sensor
* Timing belt/chain tensioner damaged

Possible Solutions:
1. First, visually inspect the cam and crank sensors and their harnesses for damage. If you notice broken/frayed wires, repair and recheck.
2. If you have access to a scope, check the cam and crank patterns. If a pattern is missing, suspect a bad sensor or a slipping tone ring. Remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings for proper alignment and make sure they're not loose or damaged or that they haven't sheared the key that aligns them. If they are properly installed, replace the sensor.
3. If the signal appears normal, then check the timing chain/belt for proper alignment. If it's misaligned, check for a damaged tensioner that may have allowed the chain/belt to slip a tooth or several teeth. Also check that the belt/chain isn't stretched. Repair and recheck.

Other crank sensor codes include P0017, P0018, P0019, P0335, P0336, P0337, P0338, P0339, P0385, P0386, P0387, P0388, and P0389.

Hope helps.

My egr vaulv i dnt knw how to change it on my crown vic


It unbolts from the throttle body and the pipe is screwed into it. But are you sure you need one. They rarely go bad. Usually if you have a check engine light on for the egr valve it is because of a bad DPFE sensor or a plugged passage in the throttle body.

. Have it checked for a trouble code. It seems like a sensor problem. ( Idle position , crankshaft position, camshaft position sensors could be bad. Also the EGR valve could be bad. with a caode you can narrow it down a bit.
