You seemed to have replaced quite a number of expensive items. Please check if the heating plugs are switching on as desired and cutting off. use a tester to confirm this. Next you will need to double check the parts you have changed, The fuel pump, the injectors. Have you replaced the fuel filters, have you checked the tank for any defective fuel, water or other solvents. check this out.
start the vehicle and allow it run idle for some time. check to test the engine after it had warmed up,if you notice roughness then check for the pump calibration. Assuming that the compression is good, there is no oil consumption, no fumes this should work out the solution. Hope my advice helps you. Good day

Cylinder misfire spark


how many miles on the odometer, mines 95k.
ah a v6, P0306 is #6 misfiring. 2.5L V6
300 is all 6 misfiring.... oops.
it is. for sure.
misfire is cause by many things, only 3 in physics, but many real world. (compression + spark +fuel rates)
i works this easy, way.
i have a full scan tool not just a code reader (near useless it)
i make sure my V6 (I have an 04) holds closed loop at idle and 2500 rpm. i f not , fix that first.
easy, it is. just look, bingo, Open loop, (out of control)
fueling is out of control.
but, first i do that tune up. in the manual, 60k , 120k, 180k, see?
do that first. , spark plugs dont last foreever nor filters.
then i replace both front 02 sensors at 100k miles. there design life.
V6 has 2 front sensors. (rear can , just sit and be ignored)
if it misfires. now, i toss a coin.
compression or fuel pressure.
i can do both in 30min flat but i toss coin lands on fuel.
i check fuel pressure and its.
60psi, fuel regulator is bad,
20psi, same, or bad pump or bad 12vdc to pump, 8v to pump is bad wiring.
one thing that helps is to find out if the engine is running too rich or too lean.
and if there are cracks in the exhuast near the 02 sensors.
i force the EFI rich and lean watching both 02 sensors in my scan tool
to see if i can force them lean or rich.
on the v6, we can introduce air leaks, to the plenum.
this will cause lean, and the o2 most react to my lean forcing
or its dead.
i can force richer, if i suspect lean or 02 shows lean, by
removing the Fuel pump regulator hose (vac) and plugging hose fast.
this causes the FPreg to go to high pressure. max.
causing RICH>
i watch the 02 and see it go rich, if not the 02 is bad or you have exhaust leaks, or dead cylinder causing the 02 to fib.
you have 2 banks, and both banks are running off 1 MAF
so you can look at both 02 sensors (front) B1S1 and B1S2
and see if both react the same. to my forcing's.

i dont think you have 3 bad cops out 6. no.
if any cylinder misfires on bank one, then bank 1 o2 goes nuts
same with the Bank 2. this can aid troubleshooting having 2 banks.
the MAF can not lie for 1 cyclinder nor one bank
the 02s can lie for each bank,
both are key to diagnosis.
let me give an example say
injector 1 leaks.
causing 301s
v6
246
135 left
this is your lay out.
my guess is its not lost compression (no test guess, mostly useless)
not 2 bad cops one on each side will cause 300s
not one bad cop. as other side would be ok.
not one bad injector.
my guess, is fuel pressure is way off.
but///???
or maf running lean (dirty, spary clean it 12inches away not close)
low fuel pressure
too high fuel pressure.

all comments are for engine with 60k mile service done,
60k, 12ok, etc.

93 7.3 ford started right up after putting on new solenoid. Thank you Mr. Turcotte....NOW!!! It started up a couple of times and would die after about 5 seconds...Then would crank and crank and nothing...


Hi again. My first guess here would be fuel pump. First check your oil level to see if the diaphram is busted and letting fuel into the crankcase. That's a dead giveaway of a bad pump.
Even if you don't find fuel in the oil, I would still crack loose a fitting on the high pressure side of the pump either at the pump or the injector pump and crank the engine to see if there is fuel pressure. If you have fuel pressure, then I'm probably not the right guy to help, as I have limited diesel experience. Other guys can chime in on this request--you don't have to enter another one to get their help.

Thanks again for using FixYa, Jeff

Renault espace 2.2dci 2001 keeps stopping while driving what could the problem be? is it the egr valve and does it need a new modified feed pipe as i have heard in another forum.thANKS FOR ANY HELP


It sounds like a fuel pressure fault. What diagnostic codes are coming up? These engine are bad for internal faults with injectors.When driving the leak off from the injector goes really high and fuel pressure is lost causing the cutting out. Would check leak off from injectors while driving.

Hi i'm fixing a renault clio 03 1.5 diesel, it wont start from cold and i'v noticed that the fuel pipes coming from the fuel filter on the battery tray to the diesel pump are full of air, this happens if...


seems you have a leak somewhere in the fuel system.check all lines for moisture from fuel. Leak could be anywhere between fuek tank and injectors. Check all fuel fittings, could even be a bad seal on fuel filter. An air leak is really hard to find at times. Patience is the key, may not be a real quick fix. Good luck

Deisel leeking out from under engine . what is the most likely fault? renault traffic van


Most common fault is a crack right where the high pressure fuel hose mates the injector, or where the hose mates the injector rail. Look for black stains at those points. should you find a leak, disassemble fuel hoses with care. They remain at a very high pressure even when the engine is turned off.

My suburban is not starting. i replaced the fuel pump since there was no fuel in the line. I tested and the pump was dead. the After installing a new pump car was working great for about 2 minutes then...


Try a fuel pressure test. I once put a brand new from the dealer fuel pump in a 4.3/ When I had pressure, I then replace the injector spider in the vortec engine, to the tune of 500 bucks. I then found out that 10psi was not enough to engage the injector. It had to be 51psi or better. I replace the pump again and it worked fine. It was a hard and expensive lesson. If you do not have a manual for the vehicle, stop by an Advance and check out a Hayes manual. Section 4 on the first page will give you the specks for the fuel system.

Hope this helps.

Renault megance Dci doesn't start in the morning - injection prob


look in fuel filter you are looking for metal fillings. i suspect you have a broken high rail pressure pump. if all ok.
check the pump to see if bosch or siemens.
if bosch can you hear a wine noise for 3 seconds, this is a lift pump.
if ok i suspect a faulty injector, this stick open.
poss the fuel regulator.
crank shaft sensor.

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
