I have a 5.7 gsi pefs. it has 2 oil senders. The one you replaced goes to the gauge and detects what the pressure actually is. The other is just a switch too tell it there is pressure or not Basically a switch that grounds. See the two on the attached diagram.
On the wiring diagram for my 5.7 gsi pefs there is a pink wire in the harness that goes from distributor to the coil. I can find no information on what it does or how to check it. Does anyone know what happens if that goes bad? Or how to check it
Number 22 on the attached file
It goes in the DLC connector at the front of the engine. between the black and the black/white wires. I also bought the plug in shunt that I am thinking you have. (Plugs into distributor and has an alligator clip wire on it) That does not work on this engine. Mine is now resting in the back...
yes I did replace. The Cap and rotor have about 30 minutes on them, however the plugs are still the ones that I had in there when it was running rich. I had them out and they were a little black but nothing major that I could tell. Just a little black soot. I tested all the wires and they...
I have something somewhere I will dig it up. But yes you need to set base timing (8 btdc) I have the same motor. Instructions say to start the motor and then jump the black/blackwhite terminals with a paperclip. I have not started it with the jumper already in. My issue today is when I put...
Still struggling on my 2000 VP 5.7 gsi pefs. Finally got the correct injectors and seem to have resolved my rich condition. Now when I set the timing with the jumper it seems to search a little for idle and the timing mark moves a little back and forth. When I pull out the jumper and bring...
Any more luck? John (BoatsUnlimited) is not finding anything wrong with my mefi. He ran it for over an hour and even heated it to 140 degrees and nothing. I am so tired of chasing this I may switch as well. Stop spending good money after bad? I was hoping to use the new fuel pump I just...
Hmmmmm You are making me think I should have gone this direction. I will be VERY interested in how it works out. I thought a LOT more had to be replaced to make it work! I should have asked.
Anyone know of performance differences between TBI and swapping a 5.7GSi to Carb?
I'm with Lou C. I would have a look at the t-stat just to make sure. Normally I think impeller pieces would make it stick open and run cold but you never know what the little pieces of impeller will do if stuck in there.
I will let you know how it goes for me with John at Boats Unlimited. He actually takes these apart and replaces components on the inside. He has my mefe 3 now but is backlogged for a week. Bob at OBD is great but I think he is on the software/programming side and John evidently can do more...
No luck on the Mercruser cross match either. I need flexible lines but metal ends. They are pretty picky on the flexible tubing needed. Looks like a coast guard rated hose and some sort of fire resistant mesh. Volvo Penta does not make life easy that's for sure. I have never used the AN...
