Long story short…we get to our campsite at Lake Powell 30 miles from the marina, set up camp and then go out to do some boarding. Engine starts fine, we idle about 100 feet away from our anchor and the engine sputters and dies. We end up being blessed by some VERY GENEROUS pontoon boaters towing us all the way back to the marina the next day! They used their entire afternoon to help us. He wouldn’t take a dime for his trouble.
Symptom…and it never changed. The engine cranks but shows no signs of starting.
First, I thought the fuel we added at camp somehow water got in the cans. We pumped out 10 gallons from the bottom of the fuel tank through the sender hole.
Next, I bypassed the lanyard switch by shorting the two wires together.
I have circuit breakers and fuses on my dual battery ACR (automatic charging relay) and they were all fine.
The fuel pump was running and pressure at the rails was ~55 psi. When we tried to start the engine it bounced from 50-60 psi.
I pulled each spark plug and added one mL of fuel to each cylinder through the plug hole. I don’t know if this is OK, but I was desperate.
I did not know of a way to check the injectors so I’m not sure if they were sending fuel into the cylinders. If you could point me in the direction of some good ways to check them, I’m all for it. I don’t recall the smell of gas when I removed the spark plugs but since I was adding gas...
The circuit breaker on the engine was not popped and I checked for continuity across the bolts on the rear. All good.
I had a spare cap, rotor and ignition control module. Swapped them in various combinations.
I checked the spark using a wire off one cylinder with a spare spark plug touching a ground wire and I had a strong spark.
I swapped the three relays (Fuel pump, ignition, ECU I believe are their functions) to see if one was bad. Fuel pump primed to ~55 psi and nothing changed.
I looked at the three 15 amp fuses for the relays and they all looked good.
I looked at electrical connections. I never found corroded leads.
I pulled the two large connectors off the ECU and they all looked in good order.
All gauges, stereo, lights, pumps, etc work as normal.
I don’t know if there are any trouble codes stored. Since the engine wouldn’t start, the “Check Engine” light isn’t any help. I am going to search for codes tomorrow using the procedure mikeg205 posted in #9 of this thread:
To me it seems like there's a bad connection, a blown fuse, or a broken circuit, I just don't know where to look.
We must have tried starting it 60-70 times but nothing changed. I had two good batteries but the Interstate battery for the engine never lost power. We enjoyed using the house battery to listen to music on our 6-hour tow back to the marina.
Any help would be great. We are hoping to take it on another out of town trip in two weeks and I don't trust others working on my boat nor that they can be timely this time of year.
