Friends, Hello!
Sorry for my English - I am from Russia

I put the engine 4.3 (L35 from Blazer) and RMB 411 on boat
I'm hooked
- Starter (without a PCM, directly battery)
- alternator
- Crankshaft sensor
- Timer (distributor)
- MAP
- EGR
- Throttle
- Coolant temperature sensor
- Connector on the spider (injector). injector 6 pcs.


Engine tries to start
Filed the first two pulses to the injector. Then there is the pulse.
This is very similar to the anti-theft system (immobilizer).

Say to PCM 411 is anti-thief system (Pass Key, which powered by BSC).

Or the engine does not start due to other reasons?

Engine and PCM taken from two different cars

These PCM
serv.no. 12200411 DFNN

HDW NO.09386530

Thank you!!
