i cant figure out whats wrong i do somthing to it fix the problem but then another one comes up....
ok i did a motor swap d15 dpfi to d16 mpfi.....(91 si)
got the write ups...three that i found.. all basicly the same stuff...
rewired things like said in the write ups...
turned key over and will run but has a bit of sputter to it... put it in gear and it wants to die... which i looked at thought i fixed it so now it will run and sputter but will drive, only to 3500rpm..all of which will go away and come back.. wtf

so now i am not getting power ot the ecu.. fuses are good battery is charged. the car will turn over just will not start..WTF

not getting any thing on the ecu.not lights to show power no codes just the check engine light stays on...

now i have been given multiple ideas as to what is wrong

injectors bad
wrong year injectors
not getting fuel to them
wiring
codes that i have been getting 9 16 and 20 all go away and come back????

9 no 1 cylinder pos.. goes away and come back???
16 injectors more offten than 9
20 eclectical load which i changed my ground and went away..

this is a complete si motor with si dizzy and si computer(PM6)?? pulled the si harness from car at junk yard..from si.

i am not having luck with this car any help would be great if you need any more info please ask i will give it to you help!!!

 

Have you tried a known-good distributor? They're usually bad on junkyard engines.

Sputting while driving can be due to a lot of fuel or a bad ignition system, I'm pretty sure.

I did the same thing to my car about a week ago...my only problems is I blow alil more oil then usual...and I used to overheat....a new T-stat and radiator cap fixed that......

Im throwing a code 1(02 is bad) and 20 .....

How can I change my load on electricity......redo the negative battery terminal...I dont want my **** to get fried

BTW mine sputters too....ive been told with the MPFI swap...youll run hella rich so I think thats what its doing.....cant wait till I get a s AFC

 

if the motor came from a junkyard, more than likely it is bad unless your motor was a rebuilt motor was rebuilt
I would say more than likely, the motor is bad!
I mean it did start, so I am probably wrong, but I would never in my life buy a junk yard motor unless I was planning to rebuild it

 

my junk yard motor pulled me to 15.2 before I destroyed my car... it all depends on their integrity.

 

not junk yard motor from ex-friends car ran when took out of car!!!

i am thinking computer because of the diffrent codes and that they go away and come back..its ODD..but not sure..

in what oreder do your plug wires go? mine right now are 1324 is that right? i cant remember what order they cam off my motor.

i did replace the main and rod bearings..the motor does not smoke..it just gives codes at random.. and now the computer gets no power..WTF.

ireally dont know what to do now..

 

if the computer light stays on you have a bad ecu...

 

the wires go 1-3-4-2 in a clockwise manner. that maybe part of the problem. and the #1 cylinder mark is the C with a circle around it.

 

Yikes. You buy a junk yard engine its safe to say, You neeed to change over the basic, Dist,plugs,and that stuff. if it does not even turn try the starter

 

I've been trying to help him out with this, When he first got it together it was starting, but the idle was surging a little, and it wouldn't rev past 3500 rpm (this is when he was getting the codes). now it's not running at all, it's turning over, just not firing up. I'm thinking one of his wire splices has come loose or is touching another wire (original prob) but now that has fried the ECU. I haven't accually seen the car in person, but this is what I gathered from our IMs. anyone else have any other Ideas?

 

the rule of thumb for a car that won't start is:

1. check for spark. check all the spark plugs to see if they all spark. if they don't continue down this road.

2. check for fuel.

that should let you know where to start looking.

 

your problem is that your sparkplug wires are on wrong.

the have to be like this

Cylenders are: Passengers side 4-3-2-1 Drivers side

On distributor

Firewall 3-4 Radiator
1-2

thats why your car wont run right
