2000 5.7 gsi problem

[SD2600]

Ok I think we have it licked, as it turns out my dash tach calc was way off. We went off the computer and what we thoughts was 3300 rpm was it hitting the rev limiter at about 5100...,. Sometimes the simple things r overlooked..... I took it out in the bay and the first key Crank didn’t want to turn over.... I gave it some neutral throttle and it caught.... idled out and it preformed awesome through all rpm ranges.... back on the trailer and Home.... on the muffs the first key bump didn’t want to start it, again with a lil neutral throttle and it caught and idled at 600 and sounded as it should for the motor flush.... I don’t wanna be greedy but shouldn’t a tbi not need any throttle to start?

also if anyone else needs to source the connectors for the J terminals. obd diagnostics had them, and bob is awesome to work with as i have dealt with him twice testing my mefi3

also important to note, we cleaned the high pressure pump as it had a lil debris in the low pressure side. changed the plugs, manifold and riser on the port side, mech though there might be a lil h20 intrusion...

This is unreal, we been chasing our tails all this time. No one could hear or feel the difference between 3300 easy cruise rpm and wide open 5100 rpm.

Honestly the motor did not sound like it was running at 5k I was kinda supprised

Not sure if I should start another thread but I still have yet to take the boat out and not break down...

so today I had a planned fishing trip.. drop the boat in fire it up with a bump of the key and all is well.. I start to motor out just in gear.. maybe 5 knots and I see the temp climb... gets a lil got so I shut it down and drop anchor

while it’s cooling down I pull the brand new impeller.. looks great.. no leaks. Good o ring.. and the new bearing spins.. the housing is also new and free of grooves..

i fire it back up and the temp climbs at idle so I shut it down and call a tow...

back at the house I replace the thermostat o ring and gasket.. I also pull the drive and inspect the hose and plastic fitting that the h20 is pulled from...

i pulled the intake hose to the impeller and back flowed with a hose and water flowed out the drive.

With the hoses off the manifolds I start it on the hose... a few min pass and h20 flows out both hoses.. I shut it down. Connected the hoses to the manifolds and fired it...

ran for 25 min at idle on the hose and the temp is solid at 170

take it back to the bay and before I can get it to the dock the temp climbs.. I shut it down.. wait 5 min fire it up give it a lil neutral rev and the temp settles at 170... I say what the hell take it out if the no wake zone and get it on plane.. after 3-4 min I drop back to neutral... temp imidiately climbs... I shut it down and call a tow

i didn’t shoot it with a temp gun but both risers are hot to touch..

frustrated, defeated... but happy I made it home safe and got to give my two boys a bubble bath tonight..

Yes I would start another thread, there will not be many wanting to read thru all the post to get to this issue
