I bought a 99 with a blown engine for 1K. It overheated. Removed the interior. Al Angulo replaced the engine and radiator, We're not getting spark. Fuel pump works when bypassed, changed coil pack and PCM. Lights on the dash come on. Anything we're supposed to leave plugged in out of the wiring harness that you would normally not worry about in a 1.6? What are we missing??? Johnny

Ok im helping John with the car and here is what we have. He purchased the car NOT running. The radiator was cracked and the engine full of water. John gutted the interior down to the fire wall and had TC Design install a cage. I got the car and installed a replacement engine. When we went to start the car it didn’t start. I checked fuel pressure and spark, we have neither. The fuel pump realy is getting power and the main relay is getting power long story short is everything is getting power but the ECU wont command anything to activate. We replaced the coil pack, crank poison sensor, ECU. Ive jumped the fuel pump relay and got it to work but with no spark or active injectors it wont start. The dash is still out of the vehicle and there are at least 15 connectors that don’t have a home. One harness is cut off altogether, I think it might be the radio. We have the instrument panel plugged in and it is working. we are now thinking of a new harness. If any of you have built a 99 spec could you PM me? Any help would be great. AL

Just worked through a starting issue with no spark. The black rubber surrounding the orange plug had come forward and was keeping the connection from being made for the crank sensor.
Check the big fuses under the hood on the pass side?

big fuse is ok . Major problem is no injector drive. no ecu comands. Found out that everything runs through the instrument cluster. I am going to try a differant cluster. When I worked at Ford they are the same way, they wont start without the cluster pulged in. Keep your input coming we are going to figure this out. AL

You can run the car all day with out the cluster. Look at all your grounds. I would highly suspect the one just behind the passenger headlight on the top of the frame rail. It has 4 or five ground wires attached to a common block. These wires come from the fuse/relay panel that is located on the passenger wheel well.

There is a ground wire at the TB that if not connected will keep all of the motor functions in check. Everything else will work. Also check the ground under the TB that attaches to the support bracket between the upper and lower intake.

Just took a look at the ground wires behind the head light and its ok.

Check for continuity at the ground. It can look good and still not be. I had to cut the grounding block off and re-ground everything at that point to make it run. Chased my tail for three days.

Just random thoughts, have you looked for rpm thru the obdII connector with a scan tool? Have ya pinned out ecu power and ground inputs, how about looking for ac voltage on crank angle sensor input to ecu? I love my lab scope! ECU failures are rare on 99's Jim Locke

This will sound strange.. But put a good battery in the car, it can't be weak at at all. I have had numerous issues jumping these cars. I have never got my mind around what is going on, but no less than 5 times, a freshly charged battery installation solved my non start problem. Using the jump feature on the battery charger while it seemed to turn the cars over with no poblem, they would never start. Jim

Jim, what is going on is that the ecm needs x amount of volts to operate. With a weak battery or a starter that draws too much it doesn't leave enough going to the ecm to kick in.

Could it be that Charlie is correct regarding the slow crank thing and with the booster it could be different that is I know that some boosters on a high current setting will bleed some alternating current thru and hose up some processors. Maybe that is why no start on booster???

we put a new battery in it and it still wont start. Keep in mine we dont have ANY ECU comands, no fuel pump no spark, no energizing of the mail relay. The 3 ground wires from the ECU are grounded along with the one behind the RF head light. ECU has power to it and all fuses are a go.

Ok so im gonna put my two cents in...... Had this same problem with my 99. Turn the key, no fire and no fuel pump. The solution was to plug the big blue plug up under the dash and make sure you have all the plugs plugged up correctly and they click in! Try this and hope ya get it running!

The alarms don't just splice in, they have relays that cut several major power points in the car. Are all the relays removed? Are the wires that were cut to put the relays in repaired?
1. Does the power wire to the injectors have 12V on in when the engine is turning over and when the key is in the 'run' and 'start' positions? It is the white/blue wire that comes from the main relay. Also check the black/white wire that is shared between the two ignition coils.
2. Does the RED wire with the black stripe coming out of the ignition switch have 12V on it when the key is in 'run' position? Without this connection, the starter will engage, but there will be no spark nor injection. This is a very common wire to be cut when putting in an alarm.

Johnny sent me a picture of those relays and they are not mazda.... they look like part of the alarm system to me.
The key in my mind is that if the main relay isn't clicking when the key is turned to the RUN position, the black/white wire that activates the relay is cut (which is usually part of an alarm install).

Ok Ok we got it and now IT RUNS! It only took 500 man hours. It came down to some of the harness was missing. I know more about 99 Miatas then I ever want to know. Thank you all for your input. I just wasnt going to let this one beat me. AL

Hey i wasnt told either. It felt like a knife in my gut to see a part of the harness on the new one that the old one didnt have. I wont fall for that one again.

Hey, the car looked good for $1k. He said it was his commuter car. Over heated on the way to work. Had an oil change sticker from earlier this year. I should of known, always count how many wires are under the dash before you buy, next time. J~
