serial 581295 This is a 2004 k21 motor, with a no run [no spark from any coil pack) situation. I have no schematic or wire diagrams for this specific (Komatsu, 2004 lpg k21) truck, but have checked the signal wires from the crank and cam sensors back to the ECM, (assuming the ECM inputs are the same pins on other forklift brands with 2004 K21, which they sure do appear to be) and all the fuses and relays I could find. what I don't know is where the other wires in the crank sensor circuit run, (which relay, etc...) if anyone has the schematic for this model series (lpg, coil packs), and any diagrams showing where things may be, and/or a 'legend' for the relays (which one does what), I would sure appreciate the assistance.
Thanks in advance

Fact of the week
The dot-com bubble, a period of large and rapid investments in internet-based companies, peaked in 2000 and saw the Nasdaq Composite index rise by 579%. Then the bubble imploded. As the value of tech stocks plummeted, cash-strapped internet start-ups became worthless and collapsed.
