Rocket111 trike
Hi folks got a rocket trike 2005 plate. Parked it up next day wouldn’t start, looking for a bit of advice. Used tuneecu and got an error code (p1552) coolant fan sensor. Reset ecu but bike won’t start, already replaced all fuses, relays, crankshaft sensor, batteries, starter solenoid checked all the usual stuff, plugs, fuel, fuel pump etc, turning over but not firing up, about ready to torch it, lol. any advice would be appreciated

Fan sensor should not be a reason for not starting, , little more info would help, does it crank? click? gauges sweep? does it have battery power? the gurus will chime in shortl im sure:)

Is it cranking over fast or slow?
A spray of starting fluid might narrow it down whether gas or spark.
A test light hooked to bat pos and probed at coils or injector ground will tell u if ecm is grounding them.
Seems like u r going to have a lot of spare parts.
