Question about Cars & Trucks
The engine will turn over but want start no spark at the spark plugs boots should there be a RPM signal on the dash when cranking? i don't see no signal.
The tachometer works from the pulse generated for the spark in the ECM or in the ignition control module
the meter is extremely unreliable at cranking speed so at best the needle may flicker at anything under 150 rpms cranking speed
no spark can be from
cam/crank position sensor problems
broken timing belt / chain
ignition control module
run the fault codes to get an idea of the area of failure
