Das Boat problem: Starboard motor won't start when warm.
 

This just started. When both engines on Das Boat are cold they start easily once both fuel pumps on each motor get the fuel up to 45psi. Now, after they are warm, the port engine will start easily but the starboard won't.

They are 541 BB Chebbies, TPI, and have the MEF-I Tune Port fuel injection and computer system. I'm thinking that it's vapor locking due to the fuel return line. What says OT?

:withstupid:

don't shut off the starboard engine. :slap:

Kinda hard to do that when I pull up to Whitey's Fish Camp for lunch.

don't go to Whitey's for lunch.....:slap:

or...don't start that engine until after lunch!

i have no idea how those engines work. :DAB:

Does it eventually start?
How long did it take to start?
What was for lunch?

poke a hole in the fuel lines to see if the vapor lock goes away

I ASSume one fuel pump per engine........ so to check pressure on the starbord engine.....after that, are you getting spark?? stick a timing light on one of the wires.......I ASSume an HEI dizzy and R U running injection?? if so need a scanner......if not, maybe check the voltages at your temp sensors to compare them.....air and water......

It'll start after I give it a shot of ether and then keep running like it's supposed to at proper RPM (idle at 1K rpm).

Eat a dick. I wouldn't trust your advice and wouldn't trust you to sit the right way on a toilet seat much less not be a ****ing piece of shit.

**** off. I hate you and hope you get the KungFlu a few times.

2x pumps per engine. One to get it from the tanks to the primary pump and the primary feeds the beast. Fuel pressure is measured by a guage with a tube running directly to it (them) off of the fuel rail.

Lotta lovin' in this response. :Jeff '79:

I say it only with sincerity and wholesome intentions in my little black heart that's probably 3 sizes too small. :yesnod:

That's no way to make friends.

I bet you still cash your new Presidents stimulus check :hurray:

Go back to your high horse over there in PR. Nobody really likes you here and it's been openly stated by many members.

Is the rail pressure bleeding off? Is there a start injector?

I think starboard got tired of trying to deliver your oft stated GPH fuel consumption and decided to go on strike. Tell her you're sorry and buy her a tank of 110 octane; maybe she'll forgive you. :D

Cool story bro.

Is it flooding? Does the BBC TPI ecm have a clear-flood mode you can try to eliminate that?
