fuel in oil?

[flareside_thun]

If it's hard to start once it's been sitting for awhile, chances are the injectors are leaking and washing fuel down the cylinders.

DesertBen44 here also has a really good write up on installing a quality electric lift pump in the tech articles. It completely deletes the lift pump, and you use a small block chevy lift pump eliminator cover to cover the hole your now gone mechanical pump will leave, and in doing so you will completely eliminate the possibility of fuel getting into your crankcase from there (aside from IP seals). From what I think, I would consider doing that if you have the funding.

I am considering doing it to my truck in the future to see if it helps start better...

Heres the link:

BTW how is that pump holding up? How many miles have you thrown on it?

Hey man not sure if that was directed at me, but its holding up great! Only have about 6k miles on it (it was not my daily driver until recently). It is a seriously well built looking unit and I am sure it will hold up well! I am thinking about relocating it though; dont want it to bounce around too much offroading, might move it a foot over so its mounted to teh passenger fender where the factory jack sits and toss the jack in the toolbox. Not sure yet.

You actually have a jack under the hood mounted on the fender. Now that would be a sight to see, that's gotta be one in a million.

Any fuel in the valley pan can't et into the oil pan, there is a drain in the valley pan close to the firewall, it drains over the rear of the engine/bellhousing. It is possible for fuel to get into the oilpan from leaky injectors, had it happen to me, two were bad , a gallon in 780 miles.

ok so i still have not completed this project. everything that could go wrong has. but i am getting close. i have one last question i have been following the write up in the tech section and it is very good, but what if you are a moron and bought a five pin relay instead of the four and just now realized it after soldering a bunch of connections? will it still work, or am i going to have to redo this?

 

[asmith]

while looking into this relay problem, i found this link that gives lots of good information about realys. thought it would be helpful. http://www.mp3car.com/the-faq-emporium/117895-faq-relays-how-they-work-and-how-to-wire-it-up.html so it looks like if i just leave the one pin disconnected it will work. hope this helps everyone.

 

[OLDBULL8]

Yeah, the 5 pin works just like the 4 pin only difference is a 5 pin has the normally closed contact labled 87A.

once again i shoot myself in the foot. i put a hole in my fuel filter with a drill bit. trying to save time and rush something. lesson learned. I cant get a new one til tomorrow, so everything is sitting there, just cant start it to make sure it works. also just to make sure i did it right what wire to the fss do i hook to? i could not find a good picture of it. is it the one closer to the front of the truck or back?

also found some more issues with my truck, but i will explain that in a different thread.

The fuel shut off wire is the wire on top of the pump closest to the gear cover that the pump bolts up to. You can't mix up the two wires on top of the pump. they are differant size connecters. The back wire feeds power to the pump internal advance for cold startups.
