    Also, my engine light is on and my doors no longer unlock with the press of the key pad or when manually unlocking/locking the doors. The adjustor for the driver's side seat doesn't work either.

Could be in the wiring, then, for those 2 sensors. I think they would both share the same 5 volt reference signal from the computer. When it stalls or goes into popcorn phase, a digital voltmeter (multi-meter) might help catch the missing signal, or it could be a poor connection for the ground for those two sensors, also. The ground connection would be known as an engine wire harness ground. But you can check the ground wire integrity at the sensor connector also.

To check the reference signal, ground voltmeter black lead to negative batt. terminal, and voltmeter red lead to sensor connector on the reference wire terminal (there's only 3 wires: reference (5 volt) wire, ground wire, and sensor signal wire to computer). Then turn key to ON. You should see very close to 5 volts at one of those terminals. If it had stalled and you had no signal, you would have to trace that wire back to the computer. By and by, you will probably need a wiring diagram.

Car won't start without a jump but battery okay

wont crank or wont start.??
no car starts , if it cant crank. (unless push starter (M/T magic)
that is not a trans sensor its the PRN switch.
ill answer for, wont CRANK !
it wont crank even with a good battery (charged) or jump started.
1: bad start
2: bad wires to same.
so hot wire the starter small wire, the key start line is tiny.
cranks. , starter good, no crank starter bad or cables bad.
if it cranks hot wired, then the key line is dead.
easy, huh?

I have a 97 Buick lesabre it'll die while driving the temp, battery, and oil pressure lights all come on it usually takes the car up to an hour to start. After stopped oil pressure will go to 20-25 but...

this issue sounds like u have a bad ignition control module,located directly under ur coilpak. thats wat they do wen they get hot aftr driving a while, shut off while driving(u must b loosing spark to ur plugs)an restarting wen cooled off. one way to check this for urself would b to purchase a spark checker at autozone or pepboys fairly inexpensive, an wen ur car dies, open the hood remove one sparkplug wire install tester between plug an wire, or wire an a good ground an have someone crank engine while u look at the tester bulb,if it lights up an pulses uspark is good,if it doesnt lite up at all while cranking engine ur spark is gone an thats ur problem possibly crank a sensor or the ignition module we mentioned earlier. try mounting the spark checker before the engine dies so u know wat a good spark will look like on that checker..... hope this helps good luck

No spark,replaced pcm,crank sensors,coil pack,still nothing,Bo spark

try checking the wires from the crank sensor to where ever they run because if this wire runs over the top of the engine you may find the insulation has gone hard and cracked so the wires inside the insulation have touched together ,you would be surprised how often i get this problem

My 1998 gmc envoy 130,000 has failed inspection. i had 1 sensor replace,oil filter,air filter, ac spark plug,ignition wire set, and ignition coil all replace. code#p0302 n p0453 seem to be my problem....

remove the spark plug and see if it is wet. See if it smells like gas. Put the plug in the plug wire and crank the car to see if it sparks. If so, get a compression gauge and screw it into the plug hole and crank the engine. Good compression 100lbs or better. If good suspect injector.

My car is not getting any spark from the coil


1. At the coils, check for battery voltage at the Red wires while cranking, the Black wires should be less than 0.05 volts while cranking. Pin 3 at the coils (each wire color at the #3 pin are different) using a scope watch for a 3 - 4 volt pulse signal while cranking. Red wire - battery voltage, Black wire is a ground and the White wire is the signal circuit

2. If there is no pulse signal to the power transistors, using a scanner check the POS counts (Position) should be 179 - 181 while cranking. If inconsistent, check the signal plate (flywheel/flex plate) for damaged teeth. If there is an RPM signal and the POS counts are correct, this crankshaft sensor is good.

3. On the front of the engine, mounted on the oil pan is the crankshaft sensor (REF) reference. Check the AC voltage while cranking, should be a clean sine wave that indicates the Top Dead Center (TDC) position of each piston. White and Black wires in a 2 pin connector

4. Check the Camshaft (phase) sensor AC voltage output. This sensor should also be a clean sine wave. This sensor detects cylinder number. This sensor is located in the front cover facing the cam gear. White and Black wires in a 2 pin connector.
