1997 FICHT J150ILEUC Hard to start.

J150ILEUC
Q-04283594

 

 

I have to advance the throttle to full and crank about 6 times before it finally catches then I can immediately revert to idle and all is good.   I can then turn off/on with no issues.  If I let sit for about 10 mins I have to go through process again.  Pumped bulb while starting with no apparent change.  Any common places to start looking that would lead to these symptoms?

Your 1997 was the first FICHT as it was made for the then 150 HP limit on bass boats for national tournaments.

 

Just a guess but it may be a voltage problem in getting the motor started where the ECU, ignition module, or the injectors do not receive enough power to operate. Some things to test and inspect are the regulator, stator, and system voltage during cranking. The first thing to do is to check compression, ignition, and sparkplug indexing, gap, and electrode wear. Sometimes moving the crankshaft position sensor closer to the flywheel helps, try closing the gap to 0.030"

 

If you do not have a trained technician to troubleshoot your motor, you will need a factory service manual and a laptop with the diagnostic software and some specialized tools to diagnose the engine.

Update.  Appears to be temp related.  Put in this morning cranked right up. Ran great.  Made about a 10 min run and fished for an hour made another run after about 10 min Into run felt a small surge during the run.  Fished for about 30 min.  Took a couple tries to start but didn't have to mess with throttle.  made another run. Fish 30 min then had to do the full throttle trick to start.

 

checked gap and was pretty much 030.

From your description about being temperature related, the ECU and/or the ignition module would be the likely suspects. Before condemning them, the rest of the system must be checked during those conditions when the motor will not start. Do not overlook the stator, wiring harness, or connectors that can cause problems when warmed up.  Also battery capacity and starter condition can affect proper cranking rpm which is needed to produce enough current from the alternator system to run the engine.

One more symptom that I noticed.  Reported RPMs appeared to climb also as the motor got worse.  In the morning all reported and worked as should.  Think it's around 5400rpm.  When motor became hard to start and we were heading back it's reporting 7k or a bit over.  Not erratic jumping around just seemed scaled up.

 

Is tach tied to ecu or related more to another component such as stator or ignition module or does this symptom not help narrow down any more?
