ok guys, as you see i dont have to many post, i use the search button like crazy to find most of my answers.

that being said, heres the lowdown. just did a lq9 swap in 2000 rcsb. original motor was 5.3.

the engine has a 228/228 114lsa cam - other than that the bottom end is stock. heads are basiclly stock besides dual springs.

i have everything hooked up that i know of besides 02s.

i read 1slowz71's thread about his last motor swap issues,and my truck is doing basically the same thing- the motor will turn over, but acts like it is only trying to start on 2 cylinders. it will puff a little white smoke out every couple of times. i put a light on it to see if it was getting spark and it is, but when i pull the plug its not wet. im going to try and go get a fuel psi guage today to see what my pressure is like. but i ould think i have fuel because one of my fittings on the rail was loose and started leaking.

the first thing i need to start with is the grounds. i have read plenty of threads on this, but im just not understanding fully.

to start, how many grounds (from the harness only) are there behind the passenger side head? i only see one but everybody says theres 2?

 

Have the injectors been sitting with fuel in them? My swap wouldn't start because of them being clogged.

 

yea, they have been sitting since 07. anyway to clean them out?

 

i would think that you have to have power to them to open them up while cleaning right?

 

Cool vid Neil, gonna keep that in mind for the future

 

let me know you address and what beer you drink, i swappped the injectors with some stock ones i had and she fired up for the first time!!.

on to the second issue. once i changed the injectors 2 of them started leaking from the top of the injector. can i buy new Orings , or do i have to buy all new injectors?

biggest issue, the oil pressure is not moving on my guage, i also pulled the filler neck to see if i could see oil in there and didnt really seee any. any ideas?

 

You can get new o-rings at autozone/napa/advanced etc.

...obvious question, but did you put oil in it? Is there a big puddle of oil under the truck from a forgotten drain plug or filter?

 

yea theres oil in it, no drip no puddle.

 

Did you reuse the oil sending unit from your old engine? Take a valve cover off and turn it over a few times and see if you get any oil....it may make a mess so be warned.

Did you pull the pan before you swapped the engine in? Oil pickup may be clogged...

 

oil sending unit is new. and the motor was rebuilt by local shop so everything should be clean..
