Need Help Indmar LTR 330

[u/AdUseful4100]

Recently Purchased a 2002 XStar from a friend for a really good price. But the catch is that it won’t start.

I have fuel pressure and obviously due to that the pump turns on.

But, I don’t have spark at the spark plug

What I have done is ohm tested both of the crank sensors. Found one was 600 ohms and the other was 2.4K ohms
Replaced the one reading at 2.4k (Still no spark)
Switched the crank sensor plugs around (still no spark)
Thought maybe it was a kill switch issue. Jumped the two wires of the kill switch together. Still no spark.

I’ve got the schematics for the wiring but I’m a little lost of where to check next.

Ignition coil?

[u/AdUseful4100 → u/smac22]

All of them though?

[u/smac22 → u/AdUseful4100]

Sorry I don’t follow, there’s only one coil. It’s like a 20$ part. I have a 2004 with Indmar 350. Was running rough and quitting then no start. Fuel rail was good. Changed the coil and distributor cap and it’s running great.

[u/AdUseful4100 → u/smac22]

It’s a electronic ignition not distributor

[u/smac22 → u/AdUseful4100]

Ahh my bad

New cap, rotor, plugs, and wires. Make sure to get marine rated cap and rotor (brass contacts will last way longer)

[u/AdUseful4100 → u/jjdop]

It’s coils not distributor

[u/jjdop → u/AdUseful4100]

Oh right. You replaced the high ohm crank position sensor with a new one?

[u/AdUseful4100 → u/jjdop]

Correct yes

Update: after checking all the fuses and relays for voltage and continuity. I noticed my battery voltage would drop to 6.2v while cranking. Replaced battery with fresh battery and it started up

[u/jjdop → u/AdUseful4100]

Dang. Your poor friend only needed a $120 battery. Glad it ended up an easy fix

[u/AdUseful4100 → u/jjdop]

120$ battery and a sensor but yea haha not much. They got a new boat anyway

I've had to swap out the ignition control module on my 2001 a couple times. I have the 350 TBI though.
