Chevy S10 help needed pls..

[Natesriv]

Thank god for Loan a tool! Love autozone right now. I hooked up a fuel pressure tester to the nipple next to the "spider" and I got 60psi when I primed the truck, then the pressure dropped to 55ish, when I go to crank the pressure jumps up to 60psi and continues to hold that while cranking. So really starting to think/feel injector pack is faulty, since I have spark and good pressure up to it. Thoughts?

that's what I've been saying all along

I'm only advising what I saw on Wheeler Dealers... I'm just wondering if that clogged injector(s) once it sits for a bit the particles settle..then when running they get pushed back to the injectors and boom...it bogs down again.

side note/thought...as much as I have been kicking over and pumping/hold gas peddle down, wouldnt I at least smell gas? Because I dont smell a thing after doing any of that for over 30min...

Holding the gas pedal to the floor while cranking puts the ECM in "clear flood mode" and turns the fuel injectors off.

I didnt do it all the time, only on a couple of starts..I did pour a bit more gas into the throttle body and it did start, after a few minutes of on and off cranks..it ran pretty rough,I had my foot on the peddle just enough to keep it from shutting down, when I went to give it just a little more gas it rough idled and shut down this was for about 1-2 minutes maybe, went to turn over and again only crank, poured a little more gas in again and this time it ran for about 15 secs then shut down again,still has some god awful smell.I took the top off and got access to the fuel injector pack...just what I feared, it the old style.. starting to think it never was replaced...

Check your intake manifold gasket. Also, if I am not mistaken the intake is plastic on these so check for warpage or cracks.

The symptoms are similar to an intake manifold gasket leak that occurred on my wife's Volvo 940 turbo. Though I think you are experiencing a combination of several things.

I also had a similar issue with my 97 Suburban, cause by warpage of the upper intake manifold being plastic.

ordered a BWD injector pack, only 170..best deal i could find. Also ordered a Fel Pro gasket pack to replace the top 3 o-rings. Finally got around to replacing the 3rd brake light, the stock one cracked in the middle and water was pouring in when it rained, Apparently standard cab is the norm and all after market 3rd brake lights are made only for the single cab, extended/extra cab trucks are pretty hosed unless it's just for the lens...i needed the whole thing...had to adapt the standard cab 3rd brake light, was a fun project...after i get this pig running I need to work on replacing rear drums and front disc brakes, needless to say I never replaced the rear drums....ever..and therefore wore the hell out of the fronts way faster and I guess I missed the point of no return on the rotors..those are hosed now also...Holy hell I blew stuff off way to long on my truck :-(

Any luck?

 

[xsonicLTZx]

Nothing yet, I missed the mailman today to sign for the Injectors, of course...having another one of those days..so I will pick it up tomorrow from post office and should have it back together by the afternoon...

 

[xsonicLTZx]

Fooooook, I throw my hands up....over it....I replaced the injectors, cleaned all gasket slots and mating service, took my time to put it back together...I primed the **** out of it..crank....crank...crank... did this for a few minutes...poured some gas in the throttle body, cranked again and after a couple mins of cranking, it fired up...held it at 1k rpms..it ran ruff and had tons of white smoke pouring out the exhaust...after a couple of mins it seemed like it was misfiring and my service engine soon light came up..then it shut off and all I can do is crank and no fire again......fk me and my luck.

 

[Natesriv]

Damn!

Are you sure you put the firing order back in the spots? (I'm sure you did...)

 

[xsonicLTZx]

yeah 2-4-6 from front to back pass side and 1-3-5 driver side front to back -_-. Doubled checked again, just in case...took out plug number one and it had some crude on it..not sure its enough to cause a no start..checking plug gap now also..

 

[xsonicLTZx]

re gaped to .060 according to factory rec. plug 1 had a little grim i cleaned it off.. plug 2 still looked pretty good, almost nothing on it. plugs 3-4-5-6 all had the same appearance, pretty close to plug one just minus the little bit of crud on it, but half of the electrode was dark in color along with the end part of the threads...I wiped them all clean and gaped, sprayed in starting fluid..cranked a bit then fired up..crap ton of white smoke and really ruff idle, held at 1k and revved it up to 1.5k and back down, still really ruff...then after a minute or so it runs super ruff, then shuts down...I am starting to wonder if maybe cylinder 2 is fooked? due to it looked the cleanest of the 6 plugs, like almost new still...I still cant understand how I was able to drive it around for a little bit and it ran normal I pull into my drive way and rev it up a bit just to get rpms up and it starts running ruff then shuts down and it never started normal again....

 

[xsonicLTZx]

what about this..i took the cap off and I looked at the rotor that is brand new and there is a burn mark, going from the bottom of the stem (that sticks out to make contact with the points) straight down, about an inch in length...there is a small hole at the bottom of the burn that can be seen from the inside of the rotor....

 

[xsonicLTZx]

umm yeah....replaced the cap and rotor with a new set...fired right up..but now I have a knock and white smoke.. -_- but it runs and holds an idle... not sure if its from all the **** i sprayed in the throttle body or if I may have lost a head gasket? I turned it off and turned it right back on with no issue..also have a service engine soon light on...think it might be due to the new fuel injectors....

 

[xsonicLTZx]

read around on the nets...maybe a hydro locked cylinder? any one have any experience with this? checked oil, looks clear as could be, I dont see anything out of the norm in my coolant either...and an FYI, i dumped the dexcool **** and put in reg green coolant. after i had to deal with the crap top gaskets and found a goopy pile of dex cool in one of the veins and decided id go with what didnt do that...Not sure if maybe this caused a gasket to fail..I dunno..that was roughly 20-30k miles ago before I let it sit for a year and a half.

 

[ss2000slp]

The service engine soon light is probably just a misfire code stored from running like sh*t. Local parts store can probably scan it for free just to make sure. As far as the smoke, it sounds like you've dumped a lot of crap down its throat recently. See if it clears up running for a while. Check the coolant level in the radiator and leave the cap off when you start it to see if you have bubble coming out.

 

[xsonicLTZx]

the white smoke reminds me when I did the seafoam treatment in my honda..I do get quite a bit of water coming out the exhaust pipe along with the smoke. But its clear. I also do notice a nice drip and air escaping out of a clamp just before the cat also. Thinking I might take that off and replace the bad gasket. I am just concerned about the knock I have now..Thinking about maybe a blocked up oil vein to one of the cylinders, I might try and get some of that lucas oil additive and give that a shot. When I rev it up it goes away, I dont see much in the way of metal flakes on the oil dip stick.

 

[xsonicLTZx]

pull the rad cap off and started no bubbles, oil is still clear even when running for 30min at least. fluids levels seemed all in the normal range...I think I over filled the oil, when looking at the stick its pretty far up over the top line..noticed a oil drip just before the cat where its leaking..going to pull oil plug and drain some oil out and pull the cat and see how fouled up that is...im sure this would be a cause of excessive white smoke? still have some smell of gas even after running for awhile. thinking about maybe pulling the top cover back off and see if its leaking gas out the fuel pressure regulator. I feel like im burning through more gas than I should be.

 

[xsonicLTZx]

riddle me this, opt to replace my spark plugs..I took 2-4 out, ends are dark black but the dark part is kinda sticky, not a dried burnt feel to it..took out number 6, almost as clean as new from when I took them out a day ago and wiped clean, but this time I look down in the well of the spark plug and I noticed a liquid at the base, i turned it over and popped it against my hand and had some gas come out....um wtf? thinking maybe I should remove all the top again and check my injectors or could this be a left over from all the fuel/gas starter I dumped in the throttle body...but would it of burnt off after I had it running for awhile? I dumped out id guess a quart and a half to drop the oil level back to about 75% of the stick.

 

[xsonicLTZx]

took the top back off and didn't notice anything out of the ordinary, I plugged the fuel line back in and cycled the fuel pump on and off a couple of times and i couldn't get any drips any where around the fuel injector, I felt the bleed off nipple of the fuel pressure regulator and it was dry. I noticed a pretty loud wooshing sound when i had my wife prime the fuel pump a couple of times though, I heard it in the cylinder holes, i am assuming that is the fuel shooting through the injector? I was kinda surprised to how loud it was.. normal?

 

[ss2000slp]

Sounds like you're having a great time with this truck. Before you put the new plugs in, disconnect the fuel pump relay and start the truck with the old plugs to burn out any excess fuel. Then install the new plugs and run it for a while. The fuel smell is a concern. Sure no leaks?
