2000 Harley Davidson flh, replaced cam sensor,& ignition module, still no spark. coil tested fine and even switched out coil with a known good one. crank sensor tested ok also. any ideas? @

Yes. First, in the fuse block under the hood check INJ A fuse and INJ B fuse. INJ A fuse is circuit 1039 which feeds the coil. If the fuse is OK, replace the coil electrical connector. I stock 2 of these at my dealership because they are needed quite often.
FYI P1351 is an ignition coil control circuit DTC.

Really silly questions now!
If it is an auto box! have you got in any gear other than Park??
Have you checked the immobiliser????
Crank angle sensor is ok?????
I've experienced problems with Jag's in the past! this sounds crazy but check that the coolant temp sender is not worn out and shorting on the bonnet liner! sounds crazy but this has hapened before! shorted out the entire ignition system!
Testimonial: "am trying to find out where the immobiliser is can you help please, auto box is in park, crank angle sensor is new,will check coolant sensor and advis"
SOURCE: 2003 chev malibu wont start due to lack of spark
That car has 2 crank sensors , did you replace both? One is at the front crank pulley and the other is behind and low on the engine block, above oil pan. Be sure the ICM (ign control module has a good ground, (black wire) it grounds at a bracket where the trans bolts to the engine approx at the 2 o'clock position.
Testimonial: "the check the ground was a good suggestion, i will do that at my first opportunity"

make sure your cap and rotor timing is correct double check spark plug routes (mistakes happen). maybe your timing is off in general.
SOURCE: I need a wiring diagram for a electronic ignition module.
If I understand correctly, Your bike has points in it now and you want to go to electronic ignition. If that's what you want to do, I would suggest that you go with one of the aftermarket ignition units. They're more versatile, costs less, and easier to install.
There are two types available. Your bike has a mechanical timing advance unit behind the points breaker plate. One type of electronic unit eliminates this mechanical part and makes the system truly maintenance free while the other type retains the mechanical advance unit and cost less. A prime example is Crane Cam's HI-1 unit that retains the mechanical advance and their HI-4 unit that eliminates it. Most bikes made after 1984 do not have the mechanical advance units. Since your bike does not have any of the original components left on it, I would suggest that you get one of the units that goes in the "nose cone" of the engine. It simply replaces the everything in there if you get the unit that does not use the mechanical advance. The Mechanical advance units are prone to wear and since no one ever services them, I'd suggest getting rid of it. You'll have to purchase a "timing cup" from Harley, costs about $20, a lot less than $100 bucks for needle bearing mechanical advance unit. Get the shorter screw that goes with it as well.
All you have to have with either unit is a "hot" wire going to the coil. The coil must have a primary resistance of somewhere around 3-4 ohms where a points type coil has a primary resistance of 4-6 ohms. To determine the resistance of your coil use a Digital Volt Ohm Meter and measure the resistance between the two small terminals on the coil. To wire the ignition units is usually just a two or three wire hookup that is very simple. They all come with wiring instructions.
Now, the next thing is whether you wish to stick with "dual fire" ignition or go to "single fire" ignition. Dual fire is the system that almost all Harley's come equipped with from the factory. In this type of system, both spark plugs fire when the pistons are top dead center. Since one piston is on the exhaust stroke, that spark is of no consequence and therefore is considered a 'wasted spark". In a "single fire" system, the spark plugs fire independently when each piston comes to TDC on the compression stroke. It requires either two coils or a "two in one" type coil. This added coil increases the cost of the system and to be honest with you, I cannot tell a difference between the two systems. With that in mind, I opt to go with the less expensive and simplier "dual fire" system.

Ok, this will get you started. Installing an electronic ignition system in an older Harley is easy to do. The difficult part is deciding which one to go with. Once you do that, no problem. If you have anymore questions, drop me a line at [email protected] .
To see how to hook up one of the units, go to their website and look for a "Technical" page. Go to that page and look for "installation Instructions". Print them out and it'll tell you everything you need to know. If not, I've got some different types of systems installation instructions that I can scan and send to you.
Good Luck
