so i rebuilt the motor....got it running ...i can drive it higher rpm it runs great....but at idle it misses....its throwing a cyc. 1 misfire and p0201 which is fuel injector number 1 circut condition....has anyone esle had this issue....an would re syncing the camshaft position sensor at the dealer fix this ....

 

Disconnect cyl 1 injector while idleing and see if it makes a difference in how it runs, and check injector resistance(cyl 1 and others for reference), and post results

 

Try what fox suggested. Also, you could swap the connectors between cyls 1 & 2 to see if the code still says cyl 1 (if it does, the problem is in the computer or wiring). If it now throws a code for cyl 2, the problem is the #1 injector (which it now thinks is cyl 2).

 

I have actually done that cyc 1 doesnt make a difference if its plugged in or not...if i swap ig to cyc 2 it throws both cyc 1&2 misfire

 

alright i checked the resistance on the injectors an this is what i got ...
1. 12.3
2. 14.2
3. 14.3
4. 14.4
5. 14.6
6. 14.8

 

another thing i checked to see if #1 injector was getting power with it idling an sure enough it does

 

try swapping the injectors and see if it moves to #2. if it does then replace your injectors.

 

I already swapped them out injector works fine in the #2 cylinder. I used a stethoscope to see if the #1 cylinder injector was clicking and its not used a test light to see if its got power while idling an it has power..... any suggestions

 

This is kind of a pita to do, and a two person job. But unbolt the fuel rail and remove it along wroth the injectors from the manifold (leaving the injectors in the rail), now take 6 soda bottles and put the injectors in them to catch the fuel, now with one person watching/analyzing the spray pattern and amount go and crank the engine over for about 10 seconds, then post back with results

-atomization equal between all 6?
-are all 6 spraying?
-is cyl 1 lacking in fuel delivery?

 

Also, if you notice a problem with an injector, try swapping some stuff like injector plugs to see if the problem follows

 

it has power what about a ground ?

 

just did that man...i have no fuel coming out of #1....an how do i check the ground

 

an ive swapped the #1 plug to #2 an it dont change anything

 

exact opposite way you check b4 for current

 

it is getting a ground it was pulsating the test light
