hey, my name is mike.I love my rx-7 to death buy im having quite a bit of trouble with it and i need some help. i bought a 86 gxl with a bad motor. took it out ( as you can tell by the picture)and threw in a "new" used motor with a claimed 60k and took off all emissons.



i was having a fuel issue with the front rotor not getting enough gas and the rear getting too much. so i swapped out injectors and now im getting gas to both rotors but it wont start. im getting spark but nothing.



ive tried to deflood it by pulling plugs and fuse and flooring it while i crank untill there is no more gas coming out. but then when i crank it again. no start. plugs are wet. compression sounds great. i have no idea what to do. any help would be really nice.

 

I suppose you might try new plugs. Other than that, maybe battery is tired. How's the cranking speed? Gas is reasonably fresh?

 

Did you check compression on the new motor?

 

gas is new. just put some more in the other day with some premix. idk how fast cranking speed is. i have no other rx7 starter to compare it too. compression sounded great. has all chugs and all pluses are very strong. i do not have a compression tester thou. i should be getting new plugs on tuesday and the battery was fully charged

 

Have you tried hooking any of the emissions stuff back up at least to the computer to see if that might be your problem?

 

That won't make a difference.



Check compression (with a compression tester), replace plugs, and don't floor it when starting (that's a function that works in the S5 cars, not the S4).

 

do you know your coils are good?

 

the plugs spark. they ark to the manifold when i test them

 

any ideas?

 

good ideas were given- did you check compression?



how old is the battery? Batteries can do funny things, even if they are charged they may not start a car, I have had bad cells cause a new battery not to start the car, but its probably something that is not hooked up properly- triple check everything and dont overlook the basics like firing order and other simple things.
