6-bolt crank no start

[spyderdrifter]

I recently found out my '95 gst had a 6-bolt swap done before I bought it. I've replaced/ repaired a lot of parts and still it won't start up. Those parts are as follows:
New battery
New starter
New cables for both
New plugs and wires
New ignition coils
New walbro fuel pump
New engine/ecu wire harness
New 1g cas (from '94 gst)
Newly fabricated wire harness for 1g cas
Re-pinned ecu injector pins
Swapped spark plug firing order

All fuses are good, all wire connections are good. I've triple checked all pinning and fabricated wire harnesses ffor accuracy and everything checks out. All timing marks were lined up at TDC for installation of 1g cas. Still not starting even with a jump. No CEL. I'm at a point of not knowing what else to do. I had my battery checked last night even though I've only had it a week and it had a good charge. I don't have my down pipe on since I removed it a while back to check something and never put it back. Don't think there'd be a back pressure issue for starting. Anyone have any ideas or seggestions?

Oh, sorry PainInTheAss to start cold. Ether = Starting fluid, about two dollars for a smaller can. I just sprayed for a couple seconds toward my throttle body. And yes, the temperature sensor can make it hard start, I'm actually going to check mine tomorrow.

ha ha ha.. I shoulda known what that meant. I'll get some starter fluid and check my temp sensor too, would be nice if something worked out. Thanks for the seggestions.

I just lost it, but I just read a thread.

A guy replaced all the coolant temperature sensors with 2g sensors on his 1g water neck/ t-stat housing. His hard start was fixed, and starts right up in the cold. I'm going to look into this tomorrow.

Nevermind found it.

I read through that thread but I'm not sure which gen water neck/ t-stat housing I have. I assume it's a 2g though. If you have a link to a pic of the 1g housing, that would be great. Once I figure it out, I'll just replace all the sensors to knock that out of the way. I can clearly tell, the previous owners of this eclipse didn't take good care of it at all.

I would do a compression test you can get the tester from most part stores. just pull a plug one at a time and screw in the tester open the throttle all the way and crank the engine over then read the guage they should all be within 2% of each other and over 90psi.

Does the compression test work even when the car isn't running? When I do it, how do I know what's wrong if the compression is wrong?

You want to do a compression test without the car running, it just needs to crank. disconnect the coil pack so you dont get spark and pull the mpi fuse or disconnect the fuel injectors so you dont get fuel. you dont want the car firing up on you. If you have a harbor freight near you they sell a good compression tester. its really simple to use.

heres a writeup and compression numbers you want to see http://www.vfaq.com/mods/wayback/compression.htm
