Got a renault kangoo dci 1.5 van, had new thermostat fitted and problems started i.e turns over but won't fire - will after about 20 attempts then it starts fine all day. list of things checked or changed:- crankshaft sensor, fuel rail pressure sensor, 2 new batteries, starter motor, earth strap, injectors all good, glowplugs all good. had a new thermostat put on as blowers weren't working and thats when the problem started. Codes all come back as voltage. Any ideas?
My 2001 kangoo 665D went same way showing crank sensor fault one thing lead to another and 3garages later took it too Bury Motors BURY Where they found problem to be engine control unit overheating and the original fault been pressure valve which lead to other faults.My advice is don't do it yourself don't use your local nor back street garages they don't have the proper diagnostic equipment only main dealer does and also the engine control unit is none reprogrammable as to be replaced....
I need to know if i can put 3oo m 99 fuel pump in a 98 bravada

CLICK HERE for the injector schematic.
CLICK HERE for the Ignition schematic.
Since the PCM uses info gatheres from the crank and cam sensors to calculate ignition - and there are no OBD codes - in all likelihood, the PCM itself is bad.
The Ignition Module, also transmits to the PCM.
It appears after all your testing - that the PCM is at fault.
It does not error report on itself (unfortunately).
The ignition timing is controlled by the Powertrain Control Module (PCM). No adjustment is necessary (distributorless ignition) or possible.
Please see the following....
The ignition timing is controlled by the Powertrain Control Module (PCM). No adjustment is necessary or possible.
The engines covered by this manual are equipped with distributorless ignitions, ignition timing is controlled by the Powertrain Control Module (PCM), as applicable. No adjustments are possible. If ignition timing is not within specification, there is a fault in the engine control system. Diagnose and repair the problem as necessary.
Ignition timing is the measurement, in degrees of crankshaft rotation, of the point at which the spark plugs fire in each of the cylinders. It is measured in degrees before or after Top Dead Center (TDC) of the compression stroke.
Ideally, the air/fuel mixture in the cylinder will be ignited by the spark plug just as the piston passes TDC of the compression stroke. If this happens, the piston will be at the beginning of the power stroke just as the compressed and ignited air/fuel mixture forces the piston down and turns the crankshaft. Because it takes a fraction of a second for the spark plug to ignite the mixture in the cylinder, the spark plug must fire a little before the piston reaches TDC. Otherwise, the mixture will not be completely ignited as the piston passes TDC and the full power of the explosion will not be used by the engine.
The timing measurement is given in degrees of crankshaft rotation before the piston reaches TDC (BTDC). If the setting for the ignition timing is 10 BTDC, each spark plug must fire 10 degrees before each piston reaches TDC. This only holds true, however, when the engine is at idle speed. The combustion process must be complete by 23° ATDC to maintain proper engine performance, fuel mileage, and low emissions.
As the engine speed increases, the pistons go faster. The spark plugs have to ignite the fuel even sooner if it is to be completely ignited when the piston reaches TDC. Spark timing changes are accomplished electronically by the engine and ignition control computers.
If the ignition is set too far advanced (BTDC), the ignition and expansion of the fuel in the cylinder will occur too soon and tend to force the piston down while it is still traveling up. This causes pre ignition or -knocking and pinging-. If the ignition spark is set too far retarded, or after TDC (ATDC), the piston will have already started on its way down when the fuel is ignited. The piston will be forced down for only a portion of its travel, resulting in poor engine performance and lack of power.
Timing marks or scales can be found on the rim of the crankshaft pulley and the timing cover. The marks on the pulley correspond to the position of the piston in the No. 1 cylinder. A stroboscopic (dynamic) timing light is hooked onto the No. 1 cylinder spark plug wire (2.2L engine only, on the 2.4L engines, special adapters are needed) . Every time the spark plug fires, the timing light flashes. By aiming the light at the timing marks while the engine is running, the exact position of the piston within the cylinder can be easily read (the flash of light makes the mark on the pulley appear to be standing still). Proper timing is indicated when the mark and scale are in specified alignment.
WARNING
When checking timing with the engine running, take care not to get the timing light wires tangled in the fan blades and/or drive belts.
The engines covered by this manual are equipped with distributorless ignitions, ignition timing is controlled by the Powertrain Control Module (PCM), as applicable. No adjustments are possible. If ignition timing is not within specification, there is a fault in the engine control system. Diagnose and repair the problem as necessary.
Thanks for using FixYa!!
SOURCE: espace wont satrt with starter motor but starts on a bump or easy start!
sounds like the dreaded renault immobiliser ,in which case its dealer only as software encrypted.whats happening is the immobiliser is stopping it from starting when key is in start position cranking but it will go with a bump as starter motor key position not activated .try a wire from battery to small connector on starter motor .if it starts which i think it will then you know what to do ...old fashioned way with a push button.but are you getting prepared to lay the golden egg ???just in case

i had a similar problem and called the dealer during lunch hour. i talked to a mechanic, the distributor in these vehicles is plastic, and is prone to cracking.not just the cap but the body also, I have been taking the cap off and wiping the moisture out of the cap. or replacing the cap but the problem is I need a new distributor. just a cheep way to get rolling is cleaning the inside of the cap, especially when it is very damp or the outside temp changes alot during the day. good luck.
SOURCE: 95 Jaguar XJ6 will not start and No codes present?
During cranking @crk sensor u should see up to 1 ac volt. Also if cam position sensor is @ fault u may not get a code, internal fault. Cam sensors are not availible,but rebuild kit is availible. The engine has to be set to top dead center aligning mark on crank pulley & tab aswell as mark on cam sensor itself.
Testimonial: " It was the CAM Sensor! All is well and our Jaguar is back on the road!! THANKS!!!"
