Blown timing caused by sucking up some of that there drink? If you hydrolocked the engine - even to a slight degree, you may have bent/twisted some internals pretty bad when the cylinders tried to compress on some water. I would say to leave it parked out in the sun for the next couple of days and then try to get it to kick over. Let it dry out completely. But I have a niggling little gremlin in the back of my head that says you may have found a way to kill a Blazer.

Rent or buy a fuel injection "noid light" and plug it into the CPI injector harness on the lower driver's side of the upper intake. If it flashes, you have injector pulse. If it does nothing, well - something's not right indeed. Check also for a working fuel pump, and of course, check fuel pressure at the test port on the driver's side rear of the upper plenum. There will be a red test lead with a round lug on the fender well on the driver's side of the truck. Jumping that to +12v battery current will force the pump to prime and run, regardless of fuses, relays and oil pressure switch. I am really hoping that after she sits for a few days, she'll kick right over. Good luck man... you'll need it.

EDIT: If you have tried and failed to start the truck, your battery may be too low to get full prime on the fuel system. Charge the battery overnight @ 2 amps or use a donor/helper battery and jumpers to assist. I am sure others will come along with ideas on what to try next.

thanks for you help where is this test lead that you speek of i cant seem to see it?

[wolfox]

Driver's side fender well, it will be red. Mine's faded to a flamingo pink, being an older truck too - but it will just look like a loose wire hanging out there in space between the side of your ABS/brake booster assemly and the fender well. It will have a large, circular lug on it's end to facillitate jumping it to any 12v source, as long as it shares a ground with the truck. Have an assistant with you to listen for the 'whirrrr" of the pump in the tank. Since this test lug bypasses *everything* in the truck's electronic layout to power the pump, if the pump does not spin, you may have sucked in water and seized it up. If it spins, then I would wonder if you do have a little more water than usual in the tank. Also of note, change your rear differential oil. The breather for that is up against the belly of the truck and if you got stuck deep and long enough for the axles to cool, the rear diffy may be filled with water too.

k thanks she was only in the water for 4 -5 mins top and just the front end went in I will look for the lead the pump is working gitting good pressure.

Will this lead open the injector ports??

Thanks for the help ill send you a video when i get it running again
( I hope)

[wolfox]

No, this only checks the most basic functionality of the pump. It will not cycle the injection system...that's controlled by your ECM. If your sensors and ECM are working properly, a noid light will determine if you're getting a pulse to fire the injector. Naturally, no injector pulse, no running. :P I am hoping that the ECM also did not get drowned. It may have to just sit and dry out for a few days before she'll kick over again. The magic brain box of these trucks or any vehicle do not work well when they have water sloshing in them.

*Bump*

Any luck at all, srcq? Does your beast live? Still stringing up the kites to attract lightning?

[srcg]

still workin on it thinking it may be the fuel pressure regulator.
Checked the pressure and i'm just getting a dribble I have loan of a guage tommorow we will see



Do you know if I can post a vid clip on here for others to see what not to do?

[wolfox]

Yeah, but you will have to host it on another site and then post the link here for others if you want to share.
