Problems with cold starting after messing about with injectors.
I had the injectors out my 1993 Surf SSRX 2.4. Took me a while to dig down to them – air inlet manifolds off and also the glow plug spreader bar had to come out. Had injectors checked by a specialist – no problem so put them back in. Put truck back together – all seemed well. Still loads of black smoke but I’ll tackle that later on....
However now when I try to start it on a cold morning it really does not want to start – prior to messing about with the injectors it would start after 2-3 seconds of cranking – very good, now it takes a disconcerting 10 seconds before finally kicking into life. Funny thing is, if once started, I immediately turn off the ignition and then try to re-start the engine it fires up with no problem at all.
I suspected air in the fuel lines but this should self bleed – right?
Nothing else has changed on the engine – except maybe that I disturbed the glow plug when taking the injectors out? I had another look at the glow plugs the other night – had all the air inlet hoses/pipes off again and checked out the glowplug spreader bar – all seemed fine with the multimeter – the resistance between each glow plug and chassis is around 2.9ohms which seems reasonable considering what they are there to do. The spreader bar and connecting wire to the spreader bar are all insulated from chassis (except when they are connected to the glow plugs of course). When I turn the ignition on I see about 10volts DC between the glow plug wire (the wire that runs up through the inlet manifold castings) and the glow plug heads (this is without spreader bar on). However this 10volts remains even when the glow plug light on the dash goes out – is this normal?
I may have blown the big 80amp fuse in the fuse box but that looks ok at a glance – although I have not taken it out yet.
Finally - does anyone know what the black knob sitting on top of the throttle housing does - it attaches to a diaphragm which controls a very small flapper next to the main throttle flapper - but can't work out what it adjusts..?
Anyone got any ideas?
