Can't make an injector squirt. Was trying the cold start valve and then read where it had to be cold...like real cold for California as it in the high 80's today and I see it's also connected to a temp sensor so it's no wonder why that was not squirting on start. I was thinking of it as a prime of sorts for a engine cold start.
Anyway I digress. The overall problem is I crank and nothing. I smell some fuel but no leaks. Ignition was testing using Pelican parts protocol and it all checked out. As soon as the wife get's back I will actually pull a plug and see for myself at the plug but it would seem all is well there so I'm looking at fuel. MPS ohm'd out and has tangerines new diaphragm in it. I pulled an injector and checked voltage at the 2 wire plug with the starter blazing away and I got minimal voltage. I believe it was under a volt. What should that be? Can I check the injector by applying a 12V supply to the two pins? It ohm'd out at 2.5 For the record, I primed the fuel system my applying 12V to the pump for a minute. I'm at 31 not 28 based on others who have a slightly larger displacement and that's spot on. My old problem of no 1.5 burst of the fuel pump has been fixed with another ECU. So, when that 1.5 second burst happens does it also open the injectors and prime the cylinders? So close and yet so far. Dave |

As mentioned.... 31 PSI on rail. Don't have a noid light but do get small doses of voltage at injectors. Screen in tank is brand new. I have fuel and great circulation in the system itself. Found one injector working sort of.
For ducks I'm going to try the Ammonia based window cleaner in my sonic cleaner unit for 30 minutes and then test with 9 volt that is actually 4.5 Ultimately will go the route mentioned above for the rebuild units. Basics are good. It's either fuel or fire and I have fire. thanks for all the posts. I will give an update hopefully positive. Dave |
