I replaced the rcm and I can see that it is closing. the strange thing is that there is no codes. I can hear the fuel pump and I wait till its stopped and then turn it. sometimes it starts .sometimes it doesn't. it has never completely stranded me but its embarrassing. if it threw a code at least I would have a starting point. if it was the ignition I don't think the points would close. I think it must be a wire.. crankcase wire possibly. it is possible that I have 4 faulty crank sensors but really..i think if it was a maf problem it would also affect driving ,. but I will look at that too. I think it would throw a code .
