I'm having some problems with my 54 Accord Tourer and I'm hoping someone can throw some light on it.
About a month ago my engine cut out when pulling from a side road which is on quite a steep slope and the glow plug light started flashing as air had somehow got into the fuel system. I tried manually priming the pump but couldn't get it to start so I called the AA. They primed it some more and after about 15 seconds of cranking the engine started and there were no warning lights showing so I didn't think any more of it.
About a week later I was pulling out of another side road (also on quite a steep slope) when the engine management light came on and the car went into limp mode.
I took the car to my local garage who gave me 3 fault codes:
P1384 glow plug circuit fault
P0087 Fuel rail / System pressure too low
P1065 fuel pressure lower than expected
The garage replaced the fuel filter with a genuine honda/bosch one but this didn't clear the fault codes and so they told me I may need either a fuel pump or a fuel rail and gave me Honda's prices. I paid them for their work and took the car back and since then further strangeness has happened.
Twice, once the engine has warmed up and has driven about 10 miles at high speed on the motorway (70mph) the engine would suddenly rev over 2000rpm and drive normally but the engine management light remained on.
Even more odd was that when I parked the car, left it for around 20 mins and came back to it the engine management light had switched off and the car drove normally. However when I've left the car overnight the engine management light has then come back on.
I can only think that something is happening when the engine warms up and revs to 2000 rpm for an extended period.
I've put some fuel additive in the fuel in case there was something in the fuel lines somewhere which was causing the problems but so far this hasn't helped.
I've read through all the different potential problems which may be causing it and I also wonder whether the initial fault and subsequent problems both happened on a steep slope have anything to do with what is wrong.
I'm considering doing one (or possibly more) of the following but I'm not sure which is best to start with considering I've seemingly ruled out the fuel filter already.
1 - Buying a brand new overpressure valve (like this one Bosch Honda Pressure Relief Valve F00R 001 166 | eBay
) and getting it fitted but otherwise not replacing the fuel rail or fuel pump
2 - Buying a used fuel rail system (like this one HONDA 2.2 Diesel Fuel Rail 0445214051 16610RBDE01 Civic CRV Accord | eBay
) and getting it fitted but not buying a new overpressure valve or fuel pump
3 - Buying a used fuel pump (like this one HONDA ACCORD/CIVIC/CRV 2.2 CDTI DIESEL INJECTOR PUMP | eBay
Therefore please can you give me some advice based on the strange way the fault seems to disappear at times but then keeps returning.
Thanks in advance
