I would like to start off giving a brief intro on what I have done to my car so you guys may understand the height of my problems/thought process.
I bought a 91 miata thats harness had been on fire at some point, however it still ran. I found wires throught the harness to be burnt. So I picked up a 1.8l and a full harness from a 94 miata. Tore my car down and began the swap. I delted, or rerouted some of the wiring. The engine bay fuse box is now in dash, and I used a mil-spec connector to feed the wiring to the engine.
I removed the egr sensor from the assembly and it is sitting in the dash by the fuse box, the sensor that is suppose to keep fuel from boiling in the rail is also sitting in th dash, the sensor that goes to the charcoal canister is also plugged in in the dash. There are 2 other 2 pin connections that are placed really close to the charcoal canisters original location. I am not too sure of their fnctions right now but I dont believ them to be important to the engines opperation.
The ecu is an early 95 that used 4 pin coils, so I dont believe it to be a problem with the 94 harness.
To set the fp, I jumped the green wire and a ground from the diagnostic connector. Turned the ignition on, and adjusted the fpr to 45psi. I thought this would be a good starting point to get the car running.
I had problems getting the car to start, I had to give it gas for it to start, and it ran like ****. eventualy I kept playing with the cas and the tps to general points and started the car without depressing the gas pedal. The car starts and runs below 100rpm, if I let out the clutch it dies. My guess is along with the low rpm, the added weight is just too much for the engine. If I hold the clutch in, the car continues to run, and dies every so often.
I thought spark may be an issue, I pulled a wire off of the coil, were 4 is, cranked the engine and it sparked over to the coil bracket. I put it back on and pulled the wire off of the the second coil, cyl 3 and cranked the engine again. It didn't spark to the coil bracket.
At that time the battery was almost dead and decided to stop for the night. I would love to put another coil on and try it but I dont have any spare coils. The junkyards were I live dont have many miatas, the cheap ones dont have any. The more expensisve ones who might have one want $100.
So I was trying to think of the least expensive way to fix the coil problem, I have seen people use dodge neon coils on 1.6's but I haven't seen it done on a 1.8l. I am really looking for a cheaper alternative to the miata coils. Looking for something I could easily find at the junk yard tomorrow, or possibly even new from an auto parts store. I believe you can get the neon coil for $50 at autozone, and they have it avaliable.
Any and all help would be greatly appreciated, thanks guys.
Thought I would post pics of the dash fuse panel location with the sensors next to it, and a pic of the engine bay. Engien bay pic is old, everything else is of course hooked up now. Intake and everything else is on.
