Also, don't just assume that because you've fitted new parts that you haven't been supplied with a faulty one! I've had a few injectors over the years returned as faulty. Only by examining the waveforms on a scope was I able to tell it was bad.
The garage will most likey have a scan tool that is capable of doing the injector pilot learn, SCV learn and the rail pressure valve counter reset, but I'd double check they have the equipment to do the injector coding! I have two high end scan tools and only Ford IDS allows me to code injectors!
By the way, don't go throwing parts at it without first of all diagnosing them. A quick voltage drop on the ignition switch would have ruled that out quicker than it took for you to order another one!
Would they work at all if injectors not coded.? i have same prob before and after new injectors, the old were coded def.
No im trying not to fix it by adding new parts now, already wasted money on that with new injectors and im dubious the old were not stil usable, i had a failed leakoff test and just bought new.!
Yes looked at live rail pressures and to my laymans eye they look OK. upto 20/25000 on start and ticks over about 23000, LOAD goes up loads adn eth rail pressure doesnt it just ten drops as van stalls.
