Just wanted to see for sure. You get power at the fuse level but the car won't stop without ether and when you are cranking you get no flashing lights on the injector noid lights?

alright guys here what i did today,
I tested the injector plugs for power. none at all. i get power to the fuses for the injectors. i took off my new distributor module and took it to oriellys to have it tested, i also had the old one tested. turns out the new module i bought was fried and the old one works great. so i took it home put it all back together and still, no fix. i also decided to change the coil out with another new one i had laying around. never used. and still no fix. after all this i tryied to clear the codes again and still nothing. i think my next step is to fork up the money for an obd 1 scanner because i dont think the pin trick is doing me any good. i do hear the fuel pump prime, and my fuel presure is good. im just not getting power to the injectors and i dont have the tool to check for volts at the tps.

yes. it will not start. it will crank like its so close, but will not start without starter fluid. it is a fact that i have no power to the injector harnesses so my injectors dont even get a chance to work

From what you are saying, the injectors only pulse AFTER it gets running? After all, the ether starts it and the engine is able to continue running after that.

IIRC, the TPS is adjustable. http://www.enduringautomotive.com/tps/
IDK. I'd use my scanner but you can try unplugging the battery or going to Autozone. Supposedly they tell you to unplug the battery and turn on the light or wait for 20 mins. Never verified that personally so IDK.

no, my injector harnesses are not working at all. when i start the car with starter fluid, it will run for a few seconds till the starter fluid is gone then it stalls. injectors never come on. only the cold start injector has power. the other 8 have nothing

Here is the Code interrogation instruction;

To Clear the codes on an 87 you can simply remove the Battery negative cable for a few seconds, and reattach.

I suppose that is one way of doing it since it is a rheostat. Not sure what values to tell you to get. 1 is 5V, the other is ground and the other one should be about 0.54V. Not sure how to set it by resistance.

OK. So now what we have is the car works except it doesn't get injector pulse either when it is cranking or running. It is the starter fluid that sustains it and when it is gone, no fuel.

Is the security light on? Is the gear in correct position? If the gearshift is out the system will not allow you to start. I would think that there would be a code if VATS disabled the car. Try cranking again in 15 minutes and see that the shifter is in neutral or park

yes now we are on the same page. but now it wont crank at all after checking it for codes this afternoon. when i checked for codes, the service engine light blinked 12s three times then the anti lock light came on, then the service light blinked 3 more 12s and now the car wont even crank. i tried to clear the code and the car still wont crank and the anti lock light is still on
