Too many cranks before start and fuel consumption

[charliebrown]

I apologise if this has been covered, did a quick search but would prefer to have a straight answer to my specific problem.

I've had my car for 6 months and when i just got it, it would crank once and start. Nowadays it's taking 3ish and sometimes even more, seems to be struggling to start. Would anyone be able to tell me what's going on?

And also my fuel consumption is now at 13-15L/100km even after replacing my broken thermostat. I thought changing it would let the car run at the right temp and fix the problem but it's still chewing hard. Now i've heard o2 sensors and fuel filters may be the culprit. Is there anything i can check myself without having to take the car to mechanics? Haven't got time and wallet getting real thin since i drive daily and tank only takes me 250km.

The car is 104xxx km, automatic, integra gsi. Heavy start-stop driving, giving it the occasional boot

Thanks for any help

this "Heavy start-stop driving, giving it the occasional boot"...

Have u done a service?

u already mentioned fuel filter, an o2, but also give it injector cleaner, give it some BP95 or 98 octane, that might improve ur mileage, but also change ur driving habits, that will most improve ur fuel mileage....

O2 sensor an fuel filter is easy to change, fuel filter just get it at repco, its like 1/3 of the price, and o2 sensor

As for changing em over, its relative straight foward, just crank the motor to remove all the fuel in the lines, so theres no pressure in the lines, than just unbolt away, and as for o2 sensor, heat up the manifold, wd40 spray it, soak it, than crack it open

All i've done since i bought the car is oil change and coolant change. Due for a minor 6 monthly service in June (probably delay til July since i got no time and money). I fill up BP ultimate ever since i've bought it. The car has not seen 91 or 95 from me.

Try new spark plugs

[charliebrown]

Any you recommend in particular? I don't know much about spark plugs but i've heard iridium is good or something? Only know of NGK brand

Bosch platinums ftw

got a multimeter? theyre like $8 on ebay, $15 at autobarn. Can come in handy. check your battery, alternator.
can also be your starter motor.

To check your alternator using the multimeter do this... make sure your lights, cd player etc are turned off. Rev your car to around 2000rpm, set the multimeter to DC voltage attach your multimeter to the battery terminals (red-positive. black-negative). Should read at around 14volts. If it reads under 12volts your alternator is crap.


as above o2 sensor and fuel filter is a cheap and easy fix.

prob dont get iridium... theyre great but pricey, its only a gsi. Maybe get bosch or NGK G-power

[dougie_504]

Get regular NGK's IMO. Iridium aren't worth the extra coin.

Bring your car around after exams, we'll take the plugs out and inspect/clean them. Will show you how.

[bennjamin]

if they are NGK coppers...dont clean them chuck them and replace with a new set. the part numbers i quoted above are from the NGK website - iridiums. You can get coppers for about $5-8 each. Part number is ZFR5F-11 I believe.
