420A No spark

[96Gs-T-Eclipse]

Ok so my problem is that I have no spark on my 99 eclipse gs turbo just dropped it in. It started right up 3 times on the third time it ran for 10-15 minutes then cut out. I'm not getting spark but I am getting injector pulse. I checked my cam and crank sensor I am getting signals and the both are good I checked my asd relay its good and working I checked my PCM its good checked my wiring its all good but as soon as I disconnect my cam sensor and it try's to start it gains spark again but still won't start my target magnet and timing are both good. I'm stuck in a hard spot I need help.

What plugs are you running with your N/T-->Turbo motor? Have you pulled them to see how they look? You could try testing your coils too.

+1 on the coils, also check out the ignitor.

^ Yea, That kinda sounds like the Coil. I know that if the coil is going out and it gets hot, you have to wait for it to cool down before it will crank again. Its happened to me before on my 95.

Coil pack is good I tested it on another 420a I even had 2 spares to try. Spark plugs are brand new ngk's and I'm not losing spark threw plugs or wires. Like I said as soon as I disconnect the cam sensor it regains spark. When I first put the motor in I had the vss and coil wires swapped. I swapped them back fired right up before doing this cutting out.

What are you using to tune the injectors with? Are you sure it is spark and not fuel that you are missing? running fine and then stopping could be a plug in the fuel system. The injectors may well be opening and closing but not spraying anything.

 

[96Gs-T-Eclipse]

I am indeed getting fuel the fuel leaks out of the manifold before the turbo when it doesn't spark and I had fire shoot out of the exhaust side of the turbo when I disconnect cam sensor and it actually gets spark also checked for fuel pressure and getting proper pressure and all 4 injectors are spraying I've gone threw a quarter tank of gas trying to get it to run

 

[NoHndlbrsRqrd]

And the tuning? I am assuming since you are a turbo conversion you have upgraded injectors and hence have to tune them somehow.

Is it possible that there are larger-than-factory injectors in there that are not tuned properly and are dumping excess fuel into the cylinders? Is it possible that an aftermarket fuel pump is installed without an upgraded fuel pressure regulator? I'm leaning more towards a fuel delivery issue than a spark issue...probably not getting spark if the plugs are drowning...

I'm not getting spark from the coil it has nothing to do with fuel I ran the same injectors on my stock engine for better starts for e-85 and had no problems with them and they are only 350cc fuel is not an issue yes I have drowned the plugs once and I waited for about 15 minutes and back to the same problem. I only get spark with cam sens disconnected but cam and crank sens are good just acting like they are not in sync with each other
