Well i fixed the massive vacume leak i had and the valve problem i had. Turns out when i tightend the fuel rail the back drivers side injector wasnt seated all the way down and the rubber boot on the intake manifold was cracked almost in half. So i get in, turn the key and wait to hear the 2 second fuel pump prime and i get nothing. Try over and over and i get nothing.I know the motor should still turn over when the oil pressure switch sees oil pressure right? Well some jackass who had the car before me removed the plug that plugs into the oil pressure switch. Thats right theres nothing there, no plug no wires, nothing! Isnt this great?
So i tapped on all three relays because my crappy *** haynes book doesnt tell you what one it is and i got nothing still.
So does anyone know either
1, what one is the relay
2,where the hell the oil pressure switch wires go to, maybe i can find them and re run them to the switch.
3, any way i can re wire the fuel pump ?
Im getting close to putting this car up for sale after its done.

 

Is your SES light coming on when you put they key in the on position?

 

yep it comes on, im gonna go out and see if i got a code and test for power at the relay, i got some info from a search is this correct for a 85 2.8?
thin black/wjite wire=ground
green=key on
thick tan/white=fuel pump power(to pump)
thin orange=adl

 

actually I was just making sure your ECU/FP fuse wasn't blown.. common cause of no-prime.

EDIT: AAAAAAAAAAAAAAAAACK!!!!!!

Those wire colors are WRONG.

2.8 MPFI FP Relay Wiring:
Black/White: Ground
Orange: ECU/FP Fuse (20A near battery), Hot at all times
Tan/White: ECU Prime Output
Dark Green/White: ECU Prime Switch
Red: Fuel Pump Prime Input

Temporary hot-wire: Orange to Red

Oil Pressure Switch:
Orange: ECU/FP Fuse, Hot at all times
Tan: Fuel pump

 

thanks techsmurf, i just went out there and looked at the wires and was like wtf? now that i see your post i can see whats what. It turned out the relay wasnt putting out anything. I swiched it since i had a extra relay laying around. Now i have the 2 second hummer in the back again! Now a new battery and another oil change and i should be ok again.
BUT what about the oil pressure switch? I have no wires going to it, i know this is a safteything in case the fuel pump relay goes bad(like mine did) so the car wont shut off.Where can i find the wires? Maybe i can re run them? The two things by the oil filter have no wires on them, and no wires in sight that i could connect to them either.this has had to have been like this since i've owned the car because i didnt remove them

 

I just noticed i have like 10 qts of oil and motor flush in the motor. Maybe thats the hard to start problem? I added like 6 qts of oil and a can of the flush. I guess the pancake mix left from the blown head gasket diluted into the oil and made the level rise.I checked its all oil and flush, no coolant. It took 2 hours for all the crappy oil to come out when i first changed it after the gasket went so i know their had to be some still caked on the walls of the motor. So tomorrow i need to get a new battery and change the oil AGAIN.

 

You could aim a space heater at the oil pan for faster flow?

 

thanks ked but the oil is pretty thin now, i put in 5 30 with the flush , its thin and white from the left over pancake mix that was left in their.Theres just sooo much of it. like 10 qts! I dont know how the motor even trurned with all that in there.

 

Get back to us when it's changed..

 

reverse hydro lock anyone... :lala:

 

Note to people reading this: YES, folks. You can fill it up with oil to the point where the oil level is at the bottom of the pistons.. and no, it does NOT run like this.

 

are you saying pankake mix literally ? or referencing the motor flush? if its the first one, how did pancake mix get in your engine?

 

after the head gasket blew the oil turned to a panckae like mix. No pancake mix didnt leterally get into my motor.
When i first changed the oil i put 5 qts of 5w 30 and a can of flush, after it ran for awhile the oil level rose because it dilutted all the left over "pancake mix like oil" from inside the engine.I checked the oil. It has no gas or coolant in it. Its white from the left over crap that was in there.

 

How warm & how long did ya "restart" the engine?
Long enough to "warm engine" to the 195* temp?

 

nah not nearly long enough, can't tell you what temp it was at exacly because the air bubbles in the cooling system made my temp gauge jump all over. Like as soon as the pb blaster stopped burning off the exhaust i shut it off. I didnt wanna run it too long without changing the oil again.

 

IF ya can get the engine up in temp before ya change oil, do so.
That detail is to your advantage. I know ya combatting extreme cold, but ya now at this junction point & ya gotta go forward, correctly.
After I did my head swap, the oil was "fine", not the dance you are now doing in the cold outside.
By heating up the oil/engine ya MAY evaporate alot of the left over condensation, too.
Best thoughts

 

thankd for the idea ked but the engine is Extreamly full of oil, so full i dont wanna run it with all of that in there. Maybe ill drain some down to the full line then run it, then drain the rest.

 

Drain it all, add fresh... if it still looks like milkshake, I wouldn't trust it to protect my bearings.. but that's just me... then again, you've got the stuff there.. if it still feels like oil, drain to full, run, drain, refill..

 

the milkshakes been gone, this has a white tint to iit from the milkshake slime left over. Kinda like pouring milk in a glass, drinkin it then pouring water in the glass. Its as thin as oil so ill drain it as soon as the 6 inches of snow let me.

 

heres why my car is taking so long to get finished, every time i get almost done this happens. I just noticed how filthy my car is also. And why the hell did gm use this ugly color?

 

theirs no snow under the car, get to work j/k

 

I spoke with my parents in Poconos earlier today & I heard about that snow.
It does make the Philly streets look so attractive, it's amazing.
If ya really pissed at your car, see if it can be "moved" to be in way of snowplows & sue Philly Street Department!

 

im too late the plows already came down the street, great job they did aint it.

 

How about this for running hot. My car hasnt been even started in days and the temp gauge is at 250* I put the damn sensor in the rear of the pass side head too so im not taking it out, im just cutting the wire (yes i know watch out for the liquid inside) and putting a new gauge in with the sender in the drivers side head.

 

Did you put teflon tape (or some other sealant) on the threads of the fan switch sensor? If so, there might not be any ground. With engine temp at 230, you could unplug the fan switch sensor, and connect a test light between it and the battery's positive terminal, and the test light should light up.

 

there is no fan sensor., i took it out and installed the sensor for my manual temp gauge. I have a hayden adjustable fan switch wired to a relay so i didnt need any of the factory fan wires or sensor. (they didnt work anyway) .

 

Br()bert-

Having grown up in the snow of Minnesnowter- here's a bit of advice- bring the battery in the posh bachelor pad at night- warm batteries crank it better- and to warm up that oil? Get a metal pan, and old frying pan works- light some charcoal in it and get those coals hot (ah, make sure you do this outdoors and near the car, don't burn your hands- coals can be hot I have been told) and slide the pan under the oilpan of the engine. Throw a blanket over the front of the car if needed.

This will warm that oil right up!

If they're still hot roast some wieners later.

 

Thanks for the idea Eric. I have a brand new 700 cca amp battery behind me on the table, it still has the plastic covers over the daul terminals. The oil in the car now is pretty thin since i put 5 30 in it and a can of flush. The old oil from after the head gasket went was VERY thick. That left a thick residue inside the engine and as soon as i put the flush and 5 30 and flush in it diluted into the pan and raised the oil level way too high.

 

i found the wires for my oil pressure switch and the dash oil idoit lite hanging under my y pipe. the plug is toast so i cut and wired the switch untill i get a new plug!, im draining the overfilled oil and junk now.

 

wooohoooooooooooo!!! I changed the oil and the filter. And put the new battery in and after like 4 cranks(maybe it cranked 4 times because no oil at first? hasnt been started in like a week)it turned over and tapped like a ****. BUT IT TURNED OVER AND when i drove it around the block it had more power than it has ever had. I dont understand why since i only put a new head gasket in it and cleaned everything in the motor. Im gonna pay a mechanic to adjust the valves. No way in hell am i doing them again!After i turned it off i tried to turn it on again and it started right up! So me laying in slush changing oil in 25* weather with huge buses passing by my head paid off. :lala: :lala: Just called this garage around the corner from me and asked for a price for valve adjustment and the china man who works there tells me gm cars are "non valve adjustable" LOL news to me.

 

call another shop, hes an idiot. Most Gm engines are adjustable, some arnt (2.5l).

 

Woo!! Glad to see she's working. The extra power is probably a sign that head gasket was very unhappy.. maybe I'll have a similar result when I do mine.. though the fresh p/p heads might negate the concept of being able to tell where the power comes from.


... never, ever, ever go to that shop. All it takes is one stupid remark from a shop and as far as I'm concerned they're ignorant to the point of having no business under my hood.

 

As soon as he said that on the phone i said"ok thankyou, click" LOL.

 

Sorry the answer is CORRECT IF YA NEVER TOUCHED THE VALVES IN THE FIRST PLACE.
BUT now correct me, if ya metioned the fact you replaced head gasket & his answer was what said....

Go phone around.
Ask for hourly rate for mechaical work.
Then tell them ya switched head gasket, car runs, need their help in final valve adjustment.
That will get you a better answer.
Well Done!!

 

lol thats the thing, i told him i replaced the head gasket. I just went out and started it again, checked my oil, its SOOOOOOOOOOO clean
