Took an led. A spare ecu pin and removed two of the injector pins. Tested both while cranking..... I have pulse... Sir... Fuel pump relay works and drops voltage, but i have to manually ground fpr pin while disconnected to do it.
I took a continuity beeper and checked fc to see if it delivered ground signal while cranking or putting over.. It never did... Tomorrow while residual fuel drains in and i get one good start i will disconnect the sta pin from the ecu so to trick it to turn on FC. This way the COR turns on so the pump will run full time but the ecu wont know its starting so hopefully i get the rpm's needed for the FC to signal.. I have not been able to find any info on what rpm the ecu actually gives thd order to send the fc signal, i need a donor to test this or ask ths community.
Also, i checked spark off of the main lead from the coil and it fired nice and hot very powerful spark indeed. Ive tested compression before and its all 168-170...
What does all this mean... Well, injectors are either clogged or just dont function. I will check resistance tomorrow to see, but i have a feeling they just jave sediment in them. Injector pulse- fuel pump operation - spark- compression -
