'95 350 TBI hard starting
'95 Prostar 350 TBI
My friend and I just got this boat, changed fuel filter, cleaned screen at the bottom of the fuel pump, changed spark plugs, added SeaFoam to fuel. She now runs great (would not even get on plane before cleaning screen of fuel pump) but sometimes after shutting it off it won't fire up. So I watched the injectors while cranking, no fuel spray. Then tried it again and it would only fire up WHEN RELEASING THE KEY, not while cranking. What could cause this?

bad ECT... pull the trans lock out button - give it a bit of throttle it will start...
common problem.. you can get it at NAPA. http://www.napaonline.com/Catalog/Ca...2SB_0331888455 you can test the old one.. table of resistance in the library... this is located on port side of engine near the last spark plug.

Some opinions on Chevy forums say its the ignition module, when hot it won't send a pulse signal to the injectors when cranking. Common Chevy problem, but I'll try the ECT first.

Haha, yep sharing ownership on this '95 190 with a couple that lives on the river.
It will live at their dock all summer so I can just buzz out there for slalom/barefoot sessions whenever I get the time and I don't need to tow the X-star out as often. And I won't cry if the boat gets dirty or dis-respected......it's certainly no '93 Limited that's for sure! 1/3 of the price. ![]()

I changed mine as well - if it's original it's prolly running hot.. prolly has a yellow dot which used to be white... yellow means it's been getting hot cuz the thermal paste is long gone.. mine had the very same issue but I changed it the ICM too this year - it's cheap as well.

Thanks Mike. I'll look at it tomorrow, might take it to Autozone and have it tested.
Def going to replace the ECT since it's so cheap. Somebody replaced the starter in this boat and we noticed the large positive post is loose inside the solenoid.....this might be an issue since the ECM gets power from that post too. Going to remove starter and clean/tighten everything up. New solenoid if needed.

Not to hijack, I'm having a similar issue:
1. After a cold start, it dies after running for a few seconds. Restarts no problem. 2. Once up to temp and shut off for a few minutes, hard to restart. Apply a bit of throttle and it starts right up. Can it be the same sensor?
