SOURCE: The car cranks but won't start

Ok, check the following below--

1. Check the Ignition control Module for its operational value. it may be damaged.

2. Check the coils.
3. Check the plugs and wires.
4. Check the ECM/PCM/ECU(All represent the same device that is commonly known as the engine control computer)

Check these areas thoroughly for faults. I would also advise to replace the fuel filter and fuel pump as well.

Select start withignition switch and sometimes nothing happens. No other problems are seen. All other instrument indiations seem normal. Keep trying and, so far, it will start.

will or will not crank?
if no crank wiggle the gear selector cranking
or try cranking in neutral. (fresh contacts there)

nothing to me means it will not crank.
if A/T wiggle the shifter,
the park lock out will allow you to shift to neutral, hand brake set.
then crank.
if it wont crank now, try, jumper cable cranks next.

Not starting first time

I'm guessing by your brief description that it doesnt start first time but does after a couple of attempts? If so, i would start by looking at the tdc sensor located on the nearside of the engine bay, bolted ontop of the gearbox. This picks up a signal from the flywheel as it rotates on cranking which in turn sends a signal to injector computer. This is used to determine the position of the engine to ensure correct timing of fueling and firing. Sometimes a wiggle of the wire will determine the fault is definitely with the sensor and renault repair is for a new sensor and a modified loom.

If wiggling the wire doesnt work it could be a more serious fault i.e the injection computer is receiving a signal from the tdc sensor but in turn isnt outputting a signal to the fuel/ignition system or just a broken wire.

But hopefully a wiggle of the wire will determine the cheaper option

Hope this helps

1995 olds 88 3.8 L. Sometimes won,t start.Cranks and immediatly dies on 1 to 10 attempts.Once starts ,runs fine. already replaced crank pos. sensor. Can hear fuel pump prime up when key is on. No check...

check the ignition control module wires are shorting out? Try the wiggle test next time no start. wiggle the wires and see if it starts.This is a factory mechanic approved test procedure.

1998 ford explorer wont start

What does anti-theft light do when this happens with the key in the on position.Does it come on for a sec then turn off or does it flash rapidly? If it is flashing then anti-theft is not seeing your key for some reason.This could be a bad key or a transponder for the anti-theft.
Second thing it could be is maybe computer isn't seeing the crankshaft position sensor. When you first turn on the ignition your check engine light should come on.It should go out while cranking but if vehicle doesn't start after a few seconds of cranking,while the engine is cranking it should come back on. If it does then computer sees the crankshaft position sensor.If it does not come on while cranking then it does not see it and it will not start.If this is the case you can try and wiggle the wires to the sensor(it will be located next to the front crankshaft pulley and it reads the teeth on the back of the crankshaft pulley.
