My 99 d2 bosch wont start. It had been running perfectly I went to crank it last sat. morning, It cranks fine but wont start. I am getting fuel to the rail, (don't know the pressure) and I have spark, I have replaced the cps and checked the inertia switch along with checking all of the fuses, Ive also cleaned some of the grounds around the fuse box under the hood. I don't think my injectors are firing, anybody got a simple test for checking the injectors?
