Default my car wont start i need help??? :/

how do chaps, my car wont go

it turns over fine, good spark & fuel, it has a crank position sensor in the dizzy does'nt it? dont know if anyone is familer or known problom????

fuel pump is werrrrrrinnng away so i think thats ok, i have a walbro 255ltr per hour one on order anyway!

what can i check? i'm a bit stuck but need to persevere & get her going! it was running fine i feel somat may have broken down in the system somewhere

i have changed plugs & regapped them to just less than 1mm, new leads dizzy cap & rotor, fuel filter, it was running fine before changing these items but it was difficult to start, seemed as though fuel was'nt getting through or the spark was'nt igniting, but i've checked these & they seem ok, i have a multimeter to do other checks but i'm not sure where to start??????? any help is appreciated

i have'nt ran the ecu self diagnose yet as i'm unsure how to do it

Right chaps the car is now running but a bit on the rough side, i think the timing is out! i'm buying a timing gun 2moro so that can be sorted fairly easily!

trouble is it runs ok if a bit lumpy when warm but when starting from cold its rubbish it takes at least 5 minutes of cranking the engine over until it catches then it's like its missing on some cylinders then as the car warms up it smooths out but it takes at least 10-15mins of driving for it too feel normal-ish???

any ideas chaps

water temp sensor makes it richer on cold start.

i'll give that a go! it was runnig quite good before the boost pip broke, then i fixed that & the temp sender, gave it a proper service of all service items & fluids & now have starting troubles, i gotta crack this & go for a spin with a full tank of fuel

i want to start fitting my new components intercooler/boost controller (new-one) 255ltr pump & a few other bits & give it a good velet inside & out!

dear me!
