    5.0 GXI C no start

    Update on this still ongoing issue. Pulled the ECM out and sent it to rebuilder. No problem found but also no surprise because it was running perfectly when I pulled it. Cleared multiple codes, all likely set when I was testing, unplugging things etc when the no start issue occurred. After...

    5.0 GXI C no start

    Also might add intermittently no double beep when key is turned on.

    5.0 GXI C no start

    Thank you! Specifically what I am looking for specifically is what F3 fuse (15amp) ignition feeds. It seems that it powers the ECM as well as the ignition circuits but that’s a guess. It will intermittently blow when key is turned on or even while running. All of the diagrams I have found show...

    5.0 GXI C no start

    Cranks no start. Intermittently blows 15 amp ignition fuse. Occasionally will try and start but almost always has no spark. Replaced, ignition module, coil, and crank sensor, no change. Crank sensor does read on tach when cranking. No codes. A wiring diagram might help. Suspect ECM failure.

    5.0 GXI intermittent severe misfire

    Starting last season I have had an anomaly that I haven’t been able pinpoint. It didn’t occur for most of many trips this summer but happened multiple times yesterday. Either upon start up or sometimes when putting into reverse and making a quick stop the normally great running port fuel...

    Tach inop

    After doing a partial engine overhaul my tach worked for a few minutes and then quit. Ive checked the power and ground supply to the tach, no problems there. The signal wire is intact and has good continuity to the connection at the coil. I have tried a different coil just because I happen to...

    5.7 GLi code 42 and tach inop

    After reinstalling my motor for an upper end rebuild etc it started right up and all appeared normal. I connected my code tool and set the base timing and locked down the distributor. I removed the code tool and started it back up. I noticed at that point that the tach which was definetely...

    Cylinder head replacement casting numbers

    I have one bad head on my 5.7L GLi. I am trying to locate a suitable core. Is there a cross reference guide of some sort that would help me to determine which casting numbers or part numbers would work ? Motor s/n T1298254 Motor model # 57FDPLKD Cyl head casting # 14096217

    Engine corrosion removal and prevention

    Well, what I thought was a case of burned exhaust valves is excalating as I've found to be a common senario with anything involving boat repair. Exhaust manifold gasket surface between riser and manifolds failed,(as Don so appropriatly pointed out, thanks Don). The trickle of cold salt water...

    Burned exhaust valves 5.7 GLi

    I had been noticing a bit of a rough idle for awhile but didnt worry too much about it as it was slight. After this weekend the rough idle turned into a pretty good lope. I did some testing on it and discovered that I have burnt exhaust valves on #4 and #6 cylinders. The exhaust manifolds and...

    Very strong RFI on VHF from sonar

    I have recently replaced my old chartplotter with a new Raymarine A57d. On my first outing everything worked perfectly and I was amazed at how well the unit worked. A few months later I was able to head out for my second trip since I had replaced the chartplotter. I was picking up a very strong...

    Prop suggestions

    After being advised to replace or repair the small dings and chips in my old prop I have decided to have that one fixed and use it as a spare. I have been out boating regularly for about 6 years now and have not had the need for a spare yet, but now that I am thinking about it not having one...

    trim gauge

    I have a 1997 seaswirl striper that has a bad trim guage. I am at a loss on how to determine what brand it is or where to find one. Any Ideas I would like to keep it at least somewhat matching with the other gauges and of course it has to be matched for resistance with the sender. I have the...

    Water drain plug Sx

    I finally got the water drain plug removed from my 97 SX drive. It was alot easier to remove with the pivot housing on the bench. The plastic nipple was cracked probably from previous freezing. The plug is pretty beat up after removing and I was trying to order a new one. The schematics that I...

    VP SX Trim cylinder pivot shaft

    Ive removed my drive every year for the last 5 years that I have owned my boat. My question is should it be extremely difficult to remove the pivot shaft for the trim cylinders ? Every year I have to beat it out with a slide hammer and it usually will be stuck to the last couple of inches. I...

    Sea water pump maintainence

    Just wondering what thoughts are on sea water pump preventative repair. I have a '97 VP Sx that has about 200 hours on a rebuild that was done right before I bought the boat. I have never done anything with the pump. The temp is always around 170 or so on the gauge. I have no reason to believe...

    VP SX drive drain plug siezed.

    Well pretty much like the title says. I cant seem to get the thing to turn at all. Ive tapped on it with the impact driver as much as I feel comfortable with. Ive still got somewhat of a slot left on the head but it is deteriorating quickly. Any Ideas would be appreciated.
