My 2002 Rav4 struggles to start after it has been sat over night. on 2002 Toyota RAV4

My 2002 Rav4 D4D struggles to start after it has been sat over night, it starts eventually after 4 or five tries. Once it starts and warms up the problem disappears until it cools again. Whilst driving it struggles to pick up speed anything above 35/40 mph. Had the EGR valve removed and cleaned twice recently. OBD11 metere brings up fault P0627- fuel pump control circuit / open. Cleared code in case it was an old stored uncleared code but no change comes back with same. Also changed glow plugs recently.

you need to have it ck'd by your mech that code can be a issue beyond you. you mean spark plugs. yes ?
Hi thanks for the reply, its a diesel so its Glow plugs that I had recently changed!!
