Gu 2.8 hot start issue ?

[patrol2.8]

My gu has just started having this problem when its cold starts first time no problems but when its warm can take up to 5 goes at starting would i just need to get the new plate and o ring from nissan to fix this also thinking could be glow plugs as they may not have been changed since new i bought the car about 7 yrs ago from the original owners and it had been really well looked after never missed a service and book all stamped from the same dealer

This is a common problem on RD28 as the injector pump wears. Fitting the new cover plate should fix the starting issue for a while, it won't reverse the wear in the pump.

Glow plugs will cause difficult cold starting and cost a lot more than the $40 odd cover plate, do the cheap things first.

The cover plate is in a difficult to reach position on the side/bottom of the pump. You are basically working blind when taking it off and putting it back on. Positioning the O-ring is not easy to establish and mistakes are easily made. Use a mirror and a torch to check if the ring is properly positioned before tightening the bolts. Also, I suggest you put a tarp under the car when you work on this as it is easy to drop the ring, bolts, tools or plate when you're working in the blind and just on feel. The tarp will make it easy to find your parts back after you dropped them. (I found this on another forum, I've never worked on an RD28 myself).

You disconnect an emmissions control device and it blows less smoke................Ironic isn't it.

Not wrong there car is smoother to drive with these mods done cant say ive noticed any difference with fuel but then again there is a tent mounted uptop which will pretty much stay up there now i and did the fan simply because with a bull bar and spotlights the air flow to the scoop is interupted will eventually hook it up to a switch inside the car i figure better to try keep the air going through as cool as i can

For when you replace the plate, use some Vaseline to hold it into position.
