    Hi There
    I am a newbie here so wasn't quite sure where to post this. I recently acquired an FR-V which I got cheap because the injector seals were blowing. A garage had tried to change them but couldn't because 3 were jammed. I managed to get them out and change the washers but since putting it back together again the car won't start. It turns over fine but just won't fire. The battery went completely flat during the ordeal and I am wondering if the ECU needs to be reset?. I am thinking that it is definitely a fuel problem. The injectors were numbered and marked and put back in original order.
    no fault codes are coming up which is strange
    Any help would be greatly appreciated.

    Did you put the earth cable back on ?

    Very likely that this is the issue !

    Actually can we ascertain if we are talking about a diesel or petrol engine here.

    In fact, if you add you car to the Club Garage, everyone will immediately be able to see what car you have as the details will appear at the bottom of all your posts.

    As Speedy says it may be worth going over your work just to check everything is connected again, but could also need the fuel system pressurising / primed to get the fuel through.

    Is Patrick still trying to work out if it's a diesel or petrol engine?

    Seriously, if its a diesel, then the injector pipework can take a surprisingly long time to purge the air out IF you don't first make use of the squeezy rubber bulb thing! Honda say to do this 40 (!) times before using the starter motor. When I refitted my injectors I got bored after around 25 pumps and just relied on the starter to pump the remaining air though and it took two bursts of around 30 seconds each before it fired up. And then it ran very roughly for some time while the remaining air was pumped through completely. The high pressure fuel pump has a very low flow rate, so on its own takes ages to shift the air.

    I initially answered it as if it were a petrol engine but when I reread the OP, I thought petrol injectors don't blow.

    So I think it's safe to assume that it's a diesel, in which case it's highly likely to the fuel pressure hasn't built up yet as @Bones126 and @Zebster have suggested.

    That engine is a rat's nest of connectors, sensors and actuators. Are you sure you haven't knocked something off,

    make sure you have no fuel leaks. quite often the nipples on the injectors come loose when cracking off the high pressure pipes. the nipples in question have a 13mm hex in there centre. you will need an open end 13mm spanner and give them a nip up to make sure.

    off to get the injectors tested tomorrow with the mechanic. he thinks they were damaged taking them out. I'm not so sure and go along with the theory that the fuel line needs looking at but can't convince him......

    Wouldn't the damage be obvious? Or did you unscrew the body to fit a puller? There is a ball that can fall out!

    yes, the tops were taken off and badly corroded injectors were pulled out with a sliding hammer arrangement. what does the ball do?

    the plot thickens. there are a number of small components that can easily be lost or broken when stripping down the tops of the injectors. not forgetting that these injectors are setup at factory with a code on the top of them for quantity amount. if you are to take any injector apart they need to be calibrated and checked by a specialist before re-fit. Honda does not recommend any injector should be re-used after taking them apart. you may need new injectors @peekaybee

    Having them tested is a good idea.

    it seems that two of them are knackered beyond economic repair :no:. a fantastic case of "if it isn't broke, don't fix it" Has anyone got any recommendations on where to go to get a replacement?
    cheers

    I can't recommend a specific supplier, but I'd definitely get refurbished ones (with calibration test data in the form of an updated 6-digit code) rather than unknown secondhand ones.

    o.k got them in now but its running quite roughly(but at least its running). Do the injectors need coding? the guy who checked them said that they don't, the mechanic says they do!

    Unless these are the original injectors that have simply been reassembled, then they DO need to be coded. The 6-digit code on the top surface of the injector needs to be written to the ECU using an HDS, Snap-On machine (with correct key) or something that'll write to this Bosch (EDC16) ECU.
