Fuel Rail system Pressure too low?

[Anonymous]

Hi all

I have a 2010 1.6 GTS petrol RCZ, and have had few problems with it in the past, mostly starting with "ENGINE FAULT REPAIR NEEDED" in amber, and engine limp mode. The underlying porblems have been various but solved by the garage so no probs for a while. The last problem I had was c 4 months ago where diagnostics were run and they gave me a report that said there was a missfire and knock on cylinders and advised me cylinders needed to be cleaned. I tried to book in to get the work done but they never got back to me and the problem just went - seemed to drive ok, so I left it.

Then the other day I had the dreaded "ENGINE FAULT REPAIR NEEDED" come up again, and the car went into engine limp mode, but it did not seem as severe as previous occassions. I bought at OBDII reader and it gave me the following codes:

P0087 Fuel Rail/system pressure too low
P2177 System too lean off idle bank 1
P1336 Manufacturer control
P1337 "
P1340 "


Since I read the car, the fault is till there but now it is keeping the fan on for a few mins after I turn the engine off. Any idea what the problem is, and how much it should cost to repair? Not sure other similar spec cars have these kinds of problems consistently but I am rather fed up with the hassle this one is giving me (previously have had timing belt issues - fixed, and of course sensor problems - replaced).



thanks

I had the P0087 error code on my 1.6THP. The garage tried running a fuel cleaner through it, replacing spark plugs, HT coils, even the timing chain and some related parts. It turned out to be the high pressure fuel pump. The car misfired badly when cold (when it requires more fuel) but was fine when it warmed up. The garage finally did a fuel pressure check and it was 5psi when it should have been 50psi. Maybe the fuel pressure check is the way to go?

Get it to a repair shop as soon as possible because as mentioned above if it is the fuel pump and you continue to drive it, you can expect damage to the engine. We had the high pressure fuel pump go out on ours and got it replaced immediately.
