I have the fuel pump on it's own switch. I am pretty sure at this point it is cam timing. I tried starter fluid with the same results. A quick pop for a few rotations and then nothing.

I was finally able to get it to stumble for a few seconds and then nothing after. I'll get a pop when cranking like it's trying to start but then nothing. I talked briefly with a local tuner and he...

I haven't pulled all the plugs from the motor. They are all new and the headers make it a pain to remove them. I did pull a plug on each side and neither one of them are wet. I'm not 100% sure what...

Injectors disabled and using starting fluid it's still doing the same thing. I'm thinking I got something going on with the intake. There is fuel puddled where the map sensor plugs in. I don't think...

It's an ac Delco. It was reading 100 kpa after I swapped it a few days ago. I pulled it a little while ago and noticed it was wet with starter fluid and gas. Something has to be leaking in the intake...

What should my map sensor be reading? It's a brand new sensor.

Still looking for some advice here. All the plugs are sparking and my fuel pressure is at 58psi. It sounds like it wants to start when cranking and you can hear it releasing pressure when I stop...

I did write entire with the os upgrade. I will switch it back to manual. I'm still not sure how quickly the plug was supposed to pulse while starting. I can smell gas when trying to start it so the...

The stock file was for a manual. I am running a th350 so I thought I should change it to non elec auto. Engine>Idle>Airflow>Base running airflow>Idle Airflow does have data populated in the stock...

Here's the latest. I am now reading the IAT and MAP sensors. The OS is a 1 bar SD configuration. I believe I have made all the changes you have suggested but still can't get it to fire. I am not...

Thank you again for the info. I am not running MAF sensor. I found the stock tune for it and started over. I was able to change the OS and when I did that I was able to read RPMs. I will get to work...

I verified spark by pulling a plug and cranking. I could see spark but I felt like it wasn't pulsing like it should. I don't have a light. This was a running setup on ez efi before the computer went...

I'm new to tuning and looking for any input to help me get this buggy running. This is an LS1 with LS3 injectors and an unknown cam but believed to be 228/238 at 50 with 620 lift and 113 separation...

I was under the impression as log as the serial, vin, and ecu didn't change, it wouldn't require more credits.

I appreciate the info again. I may have lucked out on a stock tune. I went to the repository and downloaded the first stock one listed and it just so happens to have the same VIN and Serial as the...

Yes, this is the kind of info I was looking for. I bought this setup used and it did not come with the stock tune. I will need to figure out how to change the os on it. Right now it is not giving me...

I'm running the factory map sensor for an ls1. The crank position sensor has all the correct color wires green blk/ylw blue/WHT going to the correct pins on the ecu. Not sure what's going on with the...

LS1 Computer is not reading RPM's so no fuel or spark. Replaced the crank position sensor and checked all the wiring which looks good. Getting a signal from the CPS when I bump it that goes from 0 -...
