Should be able to start it up this weekend. Trans, drive and clutch bleed. All the gauges are working. I need to finish the fuel tank parameters for the segment swap. Last little bits are the evap and a rubber boot to cover the shifter hole.

 

 

 

A couple pics too. It's throwing a Cam sensor high code so I need to figure that out. When I was putting it together I used the truck cam sensor and it might be different then the LS1 sensor.

 

Couple things im working on,


A few quick details

I picked up a 98 firebird ls1/m6 roller. I purchased a 98 harness for the M6 and performed a 99+ ecu pin swap.

I started the car for the 1st time the other day. It started up and would idle erratically and die. After a few starts I got a P0343 code. I was able to pull it out of the garage and before I could drive it back in it stalled. After repeated attempts to start it, the motor would turn over and after letting off the key would make a thud sound, kind of like it was trying to fire out of sequence. It did eventually start up and I pulled it up my drive way. For fear of loosing a rod through the block, I have not attempted to start it again.

In the mean time I replaced the cam sensor and tested those wires to the ecu for continuity. All wires tested good and showed a value of .003. I double checked all wires at the ecu to ensure the pins were swapped correctly and double checked my grounds.

I did order a fuel rail mounted pressure gauge before I go any further.

The motor is an lq9 with l92 heads and ls3 intake and injectors. The motor was running great when pulled from my other vehicle back in December. I also pulled the valley cover. The cam is centered and the cam gear is not loose.

I wanted to see if anyone else experienced the same issues or had advice. I did read a lot of threads related to cam issues but it seems everyone asks but will not post if they successfully fixed the issue.


today I posted this:

I got a hold of a fuel rail pressure tester. I have 55psi strong. I cranked it up and she started strong. After going in to open loop the fuel trims all shot to 20%+ but my o2's are sitting near open air at the end of the collectors currently. The P0343 was gone but now I have P0342. I am going to get the exhaust ran before I keep trouble shooting.

I wonder of the codes could be software related? I did a fuel segment swap from a van but also did the engine and trans segment swap from another 02 fbody that showed ls1/ m6. Maybe I need to swap the engine OS back to the original. Any ideas?

I found this thread below so I may swap the wires and see if that fixes my issue. I have a 98 harness and got rid of the test port connectors.

 

Cam sensor issue fixed. When I installed the engine harness the cam sensor connector was not completely the same as the 99+. I used my cam sensor that was already in my engine and it was from an 04 silverado. I had swapped out the connectors and didn't realize the 98 connector had A and C switched because 98 fbody's had a jumper connector on the cam wires where it crossed.

Dammit, problems going away!

 

I ordered speed engineering 3" duels over the rear axles. Great price with pan hard bar relocation kit. Kit is very nice, not too thin. Will be installed Monday and I should be able to drive it.

 

On the way to the exhaust shop this morning.

 

I was able to drive her back from the exhaust shop but my tune definitely needs work. I had to unplug the maf to keep the trims from maxing out. After the maf was failed she stayed under 10% on the LTFT's. Also base running airflow. Most time I came to a stop she stalled out. It was still a pleasure to drive and was night and day compared to the Jimmy.

Used the speed engineering kit with stainless works headers. I picked up the headers used for a decent price. As of right now no problems at all with clearance but I will use BMR or Strano springs later.

 

How is the car performing ? What kind of power is it putting down ?

 

Updates

 

nothing yet, just moved to a house with a decent shop. The kmember has a bent locator pin which is messing with exhaust and drive shaft. Once I get my shop set up ill fix that and start messing with it.

It currently pulls very hard 3k and up

 

Ok, I got the k-member centered up and its straight. I installed a new steering rack. I haven't been able to work on this much this year. I am growing tired of projects. Id like to sell it with all the extra parts I have. Figure ill empty my garage and get a finished car later. as far as extra parts I have extra fenders, doors and most of the ebony interior panels.

If someone is interested, send me a pm. The trans was recently rebuilt and the motor has less then 50k on it.

 

I had someone go on a test drive a while back. He kept asking why I haven't finished the small bits. Kind of motivated me again. The front suspension has all new bushings and ball joints. I need some rear lower control arms and she gets an alignment.

Been working on my tune. The VE is close.
