d22 engine not firing

[stuart99]

morning all, im a new member thats struggling with my 2005 d22 yd25
the truck has done 110k and for a while it occasionally when driving takes what can be best described as a gulp of air giving a short splutter then back to normal, a month ago it decided not to start in the mornings so i fitted new glow plugs (our temp here is around +10deg) it still didnt want to start unless it was pre heated around 12 times or towed/bumped for about 10 meters, now it will not fire at all, i have checked that i have fuel up to the injectors and it pumps fine, this is where im struggling in knowing where to look next,, any help is most appriciated.. stu

Hey Stu, might be your MAP sensor or the crank angle sensor. If fuel is getting there and air's getting in, it's either a ratio or timing thing.
